Linus Torvalds accefff5b5 ARM: SoC updates for OMAP GenPD
These are additional updates for the power domain support on OMAP,
 moving to an implementation based on device tree information instead of
 SoC specific code. This is the latest step in the ongoing process for
 moving code out of arch/arm/mach-omap2.
 
 I kept this separate from the other driver changes since it touches
 code in multiple areas.
 
 There is one conflict in the dra7.dts file, which adds another node
 in a different branch. Watch out for adding the trailing '};'
 both times.

Linus Torvalds 48c1c40ab4 ARM: SoC drivers for v5.11
There are a couple of subsystems maintained by other people that
 merge their drivers through the SoC tree, those changes include:
 
  - The SCMI firmware framework gains support for sensor notifications
    and for controlling voltage domains.
 
  - A large update for the Tegra memory controller driver, integrating
    it better with the interconnect framework
 
  - The memory controller subsystem gains support for Mediatek MT8192
 
  - The reset controller framework gains support for sharing pulsed
    resets
 
 For Soc specific drivers in drivers/soc, the main changes are
 
  - The Allwinner/sunxi MBUS gets a rework for the way it handles
    dma_map_ops and offsets between physical and dma address spaces.
 
  - An errata fix plus some cleanups for Freescale Layerscape SoCs
 
  - A cleanup for renesas drivers regarding MMIO accesses.
 
  - New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
 
  - New SoC specific drivers for Aspeed AST2600 LPC bus control
    and SoC identification.
 
  - Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
    and SDX55.
 
  - A rework of the TI AM33xx 'genpd' power domain support to use
    information from DT instead of platform data
 
  - Support for TI AM64x SoCs
 
  - Allow building some Amlogic drivers as modules instead of built-in
 
 Finally, there are numerous cleanups and smaller bug fixes for
 Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
 Renesas, and Xilinx SoCs.
 
 There is a trivial conflict in the cedrus driver, with two branches
 adding the same CEDRUS_CAPABILITY_H265_DEC flag, and another trivial
 remove/remove conflict in linux/dma-mapping.h.

Linus Torvalds 9805529ec5 ARM: device tree updates for 5.11
Across all platforms, there is a continued move towards DT schema for
 validating the dts files. As a result there are bug fixes for mistakes
 that are found using these schema, in addition to warnings from the
 dtc compiler.
 
 As usual, many changes are for adding support for additional on-chip
 and on-board components in the machines we already support.
 
 The newly supported SoCs for this release are:
 
  - MStar Infinity2M, a low-end IP camera chip based on a dual-core
    Cortex-A7, otherwise similar to the Infinity chip we already support.
    This is also known as the SigmaStar SSD202D, and we add support for
    the Honestar ssd201htv2 development kit.
 
  - Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller
    (BMC), in the same family as the NPCM750. This gets used in the Ampere
    Altra based "Fii Kudo" server and the Quanta GSJ, both of which are
    added as well.
 
  - Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own
    Brahma-B53 CPU. Support is also added for the Asus ROG Rapture
    GT-AC5300 high-end WiFi router based on this chip.
 
  - Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores,
    meant for faster Chromebooks and tablets. It gets added along with
    its reference design.
 
  - Mediatek MT6779 (Helio P90) is a high-end phone chip from last year's
    generation, also added along with its reference board.  This one is
    still based on Cortex-A75/A55.
 
  - Mediatek MT8167 is a version of the already supported MT8516 chip,
    both based on Cortex-A35. It gets added along with the "Pumpkin"
    single board computer, but is likely to also make its way into low-end
    tablets in the future.
 
 For the already supported chips, there are a number of new boards.
 Interestingly there are more 32-bit machines added this time than
 64-bit. Here is a brief list of the new boards:
 
  - Three new Mikrotik router variants based on Marvell Prestera
    98DX3236, a close relative of the more common Armada XP
 
  - A reference board for the Marvell Armada 382
 
  - Three new servers using ASpeed baseboard management controllers,
    the actual machines being from Bytedance, Facebook and IBM,
    and one machine using the Nuvoton NPCM750 BMC.
 
  - The Galaxy Note 10.1 (P4) tablet, using an Exynos 4412.
 
  - The usual set of 32-bit i.MX industrial/embedded hardware:
    * Protonic WD3 (tractor e-cockpit)
    * Kamstrup OMNIA Flex Concentrator (smart grid platform)
    * Van der Laan LANMCU (food storage)
    * Altesco I6P (vehicle inspection stations)
    * PHYTEC phyBOARD-Segin/phyCORE-i.MX6UL baseboard
 
  - DH electronics STM32MP157C DHCOM, a PicoITX carrier board
    for the aleady supported DHCOM module
 
  - Three new Allwinner SoC based single-board computers:
    * NanoPi R1 (H3 based)
    * FriendlyArm ZeroPi (H3 based)
    * Elimo Initium SBC (S3 based)
 
  - Ouya Game Console based on Nvidia Tegra 3
 
  - Version 5 of the already supported Zynq Z-Turn MYIR Board
 
  - LX2162AQDS, a reference platform for NXP Layerscape
    LX2162A, which is a repackaged 16-core LX2160A
 
  - A series of Kontron i.MX8M Mini baseboard/SoM versions
 
  - Espressobin Ultra, a new variant of the popular Armada 3700 based board,
 
  - IEI Puzzle-M801, a rackmount network appliance based on
    Marvell Armada 8040
 
  - Microsoft Lumia 950 XL, a phone
 
  - HDK855 and HDK865 Hardware development kits for Qualcomm
    sm8250 and sm8150, respectively
 
  - Three new board variants of the "Trogdor" Chromebook
    (sc7180)
 
  - New board variants of the Renesas based "Kingfisher" and
    "HiHope" reference boards
 
  - Kobol Helios64, an open source NAS appliance based on Rockchips
    RK3399
 
  - Engicam PX30.Core, a SoM based on Rockchip PX30, along with
    a few carrier boards.
 
 There is one conflict in mt6577_auxadc.txt, which got replaced in
 another tree and modified here, the modification is already part of
 the new file.

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v5.11 kernel.

  Drivers, drivers and drivers. Not a single core change.

  Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot
  SoCs.

  As part of the modularization attempt, I applied one patch affecting
  the firmware subsystem as a functional (not syntactic/semantic)
  dependency and then it blew up in our face, so I had to revert it,
  bummer. It will come in later, through that subsystem, I guess.

  New drivers:

   - New driver for the Microchip Serial GPIO "SGPIO".

   - Qualcomm SM8250 LPASS (Low Power Audio Subsystem) GPIO driver.

  New subdrivers:

   - Intel Lakefield subdriver.

   - Intel Elkhart Lake subdriver.

   - Intel Alder Lake-S subdriver.

   - Qualcomm MSM8953 subdriver.

Mark Rutland 870d16757b arm64: make _TIF_WORK_MASK bits contiguous
We need the bits of _TIF_WORK_MASK to be contiguous in order to to use
this as an immediate argument to an AND instruction in entry.S.

We happened to change these bits in commits:

  b5a5a01d8e ("arm64: uaccess: remove addr_limit_user_check()")
  192caabd4d ("arm64: add support for TIF_NOTIFY_SIGNAL")

which each worked in isolation, but the merge resolution in commit:

  005b2a9dc8 ("Merge tag 'tif-task_work.arch-2020-12-14' of git://git.kernel.dk/linux-block")

happened to make the bits non-contiguous.

Fix this by moving TIF_NOTIFY_SIGNAL to be bit 6, which is contiguous
with the rest of _TIF_WORK_MASK.

Otherwise, we'll get a build-time failure as below:

   arch/arm64/kernel/entry.S: Assembler messages:
   arch/arm64/kernel/entry.S:733: Error: immediate out of range at operand 3 -- `and x2,x19,#((1<<1)|(1<<0)|(1<<2)|(1<<3)|(1<<4)|(1<<5)|(1<<7))'
   scripts/Makefile.build:360: recipe for target 'arch/arm64/kernel/entry.o' failed

Merge tag 'tif-task_work.arch-2020-12-14' of git://git.kernel.dk/linux-block

Pull TIF_NOTIFY_SIGNAL updates from Jens Axboe:
 "This sits on top of of the core entry/exit and x86 entry branch from
  the tip tree, which contains the generic and x86 parts of this work.

  Here we convert the rest of the archs to support TIF_NOTIFY_SIGNAL.

  With that done, we can get rid of JOBCTL_TASK_WORK from task_work and
  signal.c, and also remove a deadlock work-around in io_uring around
  knowing that signal based task_work waking is invoked with the sighand
  wait queue head lock.

  The motivation for this work is to decouple signal notify based
  task_work, of which io_uring is a heavy user of, from sighand. The
  sighand lock becomes a huge contention point, particularly for
  threaded workloads where it's shared between threads. Even outside of
  threaded applications it's slower than it needs to be.

  Roman Gershman <romger@amazon.com> reported that his networked
  workload dropped from 1.6M QPS at 80% CPU to 1.0M QPS at 100% CPU
  after io_uring was changed to use TIF_NOTIFY_SIGNAL. The time was all
  spent hammering on the sighand lock, showing 57% of the CPU time there
  [1].

  There are further cleanups possible on top of this. One example is
  TIF_PATCH_PENDING, where a patch already exists to use
  TIF_NOTIFY_SIGNAL instead. Hopefully this will also lead to more
  consolidation, but the work stands on its own as well"

Linus Torvalds 7a932e5702 asm-generic: cross-architecture timer cleanup
This cleans up two ancient timer features that were never completed in
 the past, CONFIG_GENERIC_CLOCKEVENTS and CONFIG_ARCH_USES_GETTIMEOFFSET.
 
 There was only one user left for the ARCH_USES_GETTIMEOFFSET variant
 of clocksource implementations, the ARM EBSA110 platform. Rather than
 changing to use modern timekeeping, we remove the platform entirely as
 Russell no longer uses his machine and nobody else seems to have one
 any more.
 
 The conditional code for using arch_gettimeoffset() is removed as
 a result.
 
 For CONFIG_GENERIC_CLOCKEVENTS, there are still a couple of platforms
 not using clockevent drivers: parisc, ia64, most of m68k, and one
 Arm platform. These all do timer ticks slighly differently, and this
 gets cleaned up to the point they at least all call the same helper
 function. Instead of most platforms using 'select GENERIC_CLOCKEVENTS'
 in Kconfig, the polarity is now reversed, with the few remaining ones
 selecting LEGACY_TIMER_TICK instead.

Thomas Gleixner 4083a281e3 alpha: replace bogus in_interrupt()
in_interrupt() is true for a variety of things including bottom half
disabled regions.  Deducing hard interrupt context from it is dubious at
best.

Use in_irq() which is true if called in hard interrupt context.  Otherwise
calling irq_exit() would do more harm than good.

Pull execve updates from Eric Biederman:
 "This set of changes ultimately fixes the interaction of posix file
  lock and exec. Fundamentally most of the change is just moving where
  unshare_files is called during exec, and tweaking the users of
  files_struct so that the count of files_struct is not unnecessarily
  played with.

  Along the way fcheck and related helpers were renamed to more
  accurately reflect what they do.

  There were also many other small changes that fell out, as this is the
  first time in a long time much of this code has been touched.

  Benchmarks haven't turned up any practical issues but Al Viro has
  observed a possibility for a lot of pounding on task_lock. So I have
  some changes in progress to convert put_files_struct to always rcu
  free files_struct. That wasn't ready for the merge window so that will
  have to wait until next time"

Pull power management updates from Rafael Wysocki:
 "These update cpufreq (core and drivers), cpuidle (polling state
  implementation and the PSCI driver), the OPP (operating performance
  points) framework, devfreq (core and drivers), the power capping RAPL
  (Running Average Power Limit) driver, the Energy Model support, the
  generic power domains (genpd) framework, the ACPI device power
  management, the core system-wide suspend code and power management
  utilities.

  Specifics:

   - Use local_clock() instead of jiffies in the cpufreq statistics to
     improve accuracy (Viresh Kumar).

   - Fix up OPP usage in the cpufreq-dt and qcom-cpufreq-nvmem cpufreq
     drivers (Viresh Kumar).

   - Clean up the cpufreq core, the intel_pstate driver and the
     schedutil cpufreq governor (Rafael Wysocki).

   - Fix up error code paths in the sti-cpufreq and mediatek cpufreq
     drivers (Yangtao Li, Qinglang Miao).

   - Fix cpufreq_online() to return error codes instead of success (0)
     in all cases when it fails (Wang ShaoBo).

   - Add mt8167 support to the mediatek cpufreq driver and blacklist
     mt8516 in the cpufreq-dt-platdev driver (Fabien Parent).

   - Modify the tegra194 cpufreq driver to always return values from the
     frequency table as the current frequency and clean up that driver
     (Sumit Gupta, Jon Hunter).

   - Modify the arm_scmi cpufreq driver to allow it to discover the
     power scale present in the performance protocol and provide this
     information to the Energy Model (Lukasz Luba).

   - Add missing MODULE_DEVICE_TABLE to several cpufreq drivers (Pali
     Rohár).

   - Clean up the CPPC cpufreq driver (Ionela Voinescu).

   - Fix NVMEM_IMX_OCOTP dependency in the imx cpufreq driver (Arnd
     Bergmann).

   - Rework the poling interval selection for the polling state in
     cpuidle (Mel Gorman).

   - Enable suspend-to-idle for PSCI OSI mode in the PSCI cpuidle driver
     (Ulf Hansson).

   - Modify the OPP framework to support empty (node-less) OPP tables in
     DT for passing dependency information (Nicola Mazzucato).

   - Fix potential lockdep issue in the OPP core and clean up the OPP
     core (Viresh Kumar).

   - Modify dev_pm_opp_put_regulators() to accept a NULL argument and
     update its users accordingly (Viresh Kumar).

   - Add frequency changes tracepoint to devfreq (Matthias Kaehlcke).

   - Add support for governor feature flags to devfreq, make devfreq
     sysfs file permissions depend on the governor and clean up the
     devfreq core (Chanwoo Choi).

   - Clean up the tegra20 devfreq driver and deprecate it to allow
     another driver based on EMC_STAT to be used instead of it (Dmitry
     Osipenko).

   - Add interconnect support to the tegra30 devfreq driver, allow it to
     take the interconnect and OPP information from DT and clean it up
     (Dmitry Osipenko).

   - Add interconnect support to the exynos-bus devfreq driver along
     with interconnect properties documentation (Sylwester Nawrocki).

   - Add suport for AMD Fam17h and Fam19h processors to the RAPL power
     capping driver (Victor Ding, Kim Phillips).

   - Fix handling of overly long constraint names in the powercap
     framework (Lukasz Luba).

   - Fix the wakeup configuration handling for bridges in the ACPI
     device power management core (Rafael Wysocki).

   - Add support for using an abstract scale for power units in the
     Energy Model (EM) and document it (Lukasz Luba).

   - Add em_cpu_energy() micro-optimization to the EM (Pavankumar
     Kondeti).

   - Modify the generic power domains (genpd) framwework to support
     suspend-to-idle (Ulf Hansson).

   - Fix creation of debugfs nodes in genpd (Thierry Strudel).

   - Clean up genpd (Lina Iyer).

   - Clean up the core system-wide suspend code and make it print driver
     flags for devices with debug enabled (Alex Shi, Patrice Chotard,
     Chen Yu).

   - Modify the ACPI system reboot code to make it prepare for system
     power off to avoid confusing the platform firmware (Kai-Heng Feng).

   - Update the pm-graph (multiple changes, mostly usability-related)
     and cpupower (online and offline CPU information support) PM
     utilities (Todd Brandt, Brahadambal Srinivasan)"

Linus Torvalds ee249d30fa Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov:

 - support for inhibiting input devices at request from userspace. If a
   device implements open/close methods, it can also put device into low
   power state. This is needed, for example, to disable keyboard and
   touchpad on convertibles when they are transitioned into tablet mode

 - now that ordinary input devices can be configured for polling mode,
   dedicated input polling device implementation has been removed

 - GTCO tablet driver has been removed, as it used problematic custom
   HID parser, devices are EOL, and there is no interest from the
   manufacturer

 - a new driver for Dialog DA7280 haptic chips has been introduced

 - a new driver for power button on Dell Wyse 3020

 - support for eKTF2132 in ektf2127 driver

 - support for SC2721 and SC2730 in sc27xx-vibra driver

 - enhancements for Atmel touchscreens, AD7846 touchscreens, Elan
   touchpads, ADP5589, ST1232 touchscreen, TM2 touchkey drivers

 - fixes and cleanups to allow clean builds with W=1

    for some time expecting applications to periodically busy poll
 
  - AF_XDP: improve efficiency by more batching and hindering
            the adjacency cache prefetcher
 
  - af_packet: make packet_fanout.arr size configurable up to 64K
 
  - tcp: optimize TCP zero copy receive in presence of partial or unaligned
         reads making zero copy a performance win for much smaller messages
 
  - XDP: add bulk APIs for returning / freeing frames
 
  - sched: support fragmenting IP packets as they come out of conntrack
 
  - net: allow virtual netdevs to forward UDP L4 and fraglist GSO skbs
 
 BPF:
 
  - BPF switch from crude rlimit-based to memcg-based memory accounting
 
  - BPF type format information for kernel modules and related tracing
    enhancements
 
  - BPF implement task local storage for BPF LSM
 
  - allow the FENTRY/FEXIT/RAW_TP tracing programs to use bpf_sk_storage

 Drivers:
 
  - mlx5: make use of the new auxiliary bus to organize the driver internals
 
  - mlx5: more accurate port TX timestamping support
 
  - mlxsw:

         APIs and have the drivers write a full IRQ handler, slight growth
 	of driver code should be compensated by the simpler API which
 	also allows shared IRQs
 
  - add common code for handling netdev per-cpu counters
 
  - move TX packet re-allocation from Ethernet switch tag drivers to

Mike Rapoport 5d6ad668f3 arch, mm: restore dependency of __kernel_map_pages() on DEBUG_PAGEALLOC
The design of DEBUG_PAGEALLOC presumes that __kernel_map_pages() must
never fail.  With this assumption is wouldn't be safe to allow general
usage of this function.

Moreover, some architectures that implement __kernel_map_pages() have this
function guarded by #ifdef DEBUG_PAGEALLOC and some refuse to map/unmap
pages when page allocation debugging is disabled at runtime.

As all the users of __kernel_map_pages() were converted to use
debug_pagealloc_map_pages() it is safe to make it available only when
DEBUG_PAGEALLOC is set.

Mike Rapoport fcd353a314 m68k: deprecate DISCONTIGMEM
DISCONTIGMEM was intended to provide more efficient support for systems
with holes in their physical address space that FLATMEM did.

Yet, it's overhead in terms of the memory consumption seems to
overweight the savings on the unused memory map.

For a ARAnyM system with 16 MBytes of FastRAM configured, the memory
usage reported after page allocator initialization is

  Memory: 23828K/30720K available (3206K kernel code, 535K rwdata, 936K rodata, 768K init, 193K bss, 6892K reserved, 0K cma-reserved)

and with DISCONTIGMEM disabled and with relatively large hole in the memory
map it is:

  Memory: 23864K/30720K available (3197K kernel code, 516K rwdata, 936K rodata, 764K init, 179K bss, 6856K reserved, 0K cma-reserved)

Moreover, since m68k already has custom pfn_valid() it is possible to
define HAVE_ARCH_PFN_VALID to enable freeing of unused memory map.  The
minimal size of a hole that can be freed should not be less than
MAX_ORDER_NR_PAGES so to achieve more substantial memory savings let
m68k also define custom FORCE_MAX_ZONEORDER.

With FORCE_MAX_ZONEORDER set to 9 memory usage becomes:

  Memory: 23880K/30720K available (3197K kernel code, 516K rwdata, 936K rodata, 764K init, 179K bss, 6840K reserved, 0K cma-reserved)

Mike Rapoport 6b2ad8d763 m68k/mm: make node data and node setup depend on CONFIG_DISCONTIGMEM
The pg_data_t node structures and their initialization currently depends on
!CONFIG_SINGLE_MEMORY_CHUNK. Since they are required only for DISCONTIGMEM
make this dependency explicit and replace usage of
CONFIG_SINGLE_MEMORY_CHUNK with CONFIG_DISCONTIGMEM where appropriate.

The CONFIG_SINGLE_MEMORY_CHUNK was implicitly disabled on the ColdFire MMU
variant, although it always presumed a single memory bank. As there is no
actual need for DISCONTIGMEM in this case, make sure that ColdFire MMU
systems set CONFIG_SINGLE_MEMORY_CHUNK to 'y'.

Mike Rapoport 050b2da268 arc: use FLATMEM with freeing of unused memory map instead of DISCONTIGMEM
Currently ARC uses DISCONTIGMEM to cope with sparse physical memory address
space on systems with 2 memory banks. While DISCONTIGMEM avoids wasting
memory on unpopulated memory map, it adds both memory and CPU overhead
relatively to FLATMEM. Moreover, DISCONTINGMEM is generally considered
deprecated.

The obvious replacement for DISCONTIGMEM would be SPARSEMEM, but it is also
less efficient than FLATMEM in pfn_to_page() and page_to_pfn() conversions.
Besides it requires tuning of SECTION_SIZE which is not trivial for
possible ARC memory configuration.

Since the memory map for both banks is always allocated from the "lowmem"
bank, it is possible to use FLATMEM for two-bank configuration and simply
free the unused hole in the memory map. All is required for that is to
provide ARC-specific pfn_valid() that will take into account actual
physical memory configuration and define HAVE_ARCH_PFN_VALID.

The resulting kernel image configured with defconfig + HIGHMEM=y is
smaller:

  $ size a/vmlinux b/vmlinux
     text    data     bss     dec     hex filename

Mike Rapoport 4f5b0c1789 arm, arm64: move free_unused_memmap() to generic mm
ARM and ARM64 free unused parts of the memory map just before the
initialization of the page allocator. To allow holes in the memory map both
architectures overload pfn_valid() and define HAVE_ARCH_PFN_VALID.

Allowing holes in the memory map for FLATMEM may be useful for small
machines, such as ARC and m68k and will enable those architectures to cease
using DISCONTIGMEM and still support more than one memory bank.

Move the functions that free unused memory map to generic mm and enable
them in case HAVE_ARCH_PFN_VALID=y.

Mike Rapoport 5e545df329 arm: remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL
ARM is the only architecture that defines CONFIG_ARCH_HAS_HOLES_MEMORYMODEL
which in turn enables memmap_valid_within() function that is intended to
verify existence  of struct page associated with a pfn when there are holes
in the memory map.

However, the ARCH_HAS_HOLES_MEMORYMODEL also enables HAVE_ARCH_PFN_VALID
and arch-specific pfn_valid() implementation that also deals with the holes
in the memory map.

The only two users of memmap_valid_within() call this function after
a call to pfn_valid() so the memmap_valid_within() check becomes redundant.

Remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL and memmap_valid_within() and rely

Mike Rapoport 214496cb18 ia64: make SPARSEMEM default and disable DISCONTIGMEM
SPARSEMEM memory model suitable for systems with large holes in their
phyiscal memory layout. With SPARSEMEM_VMEMMAP enabled it provides
pfn_to_page() and page_to_pfn() as fast as FLATMEM.

Make it the default memory model for IA-64 and disable DISCONTIGMEM which
is considered obsolete for quite some time.

Mike Rapoport ea34f78f3d ia64: forbid using VIRTUAL_MEM_MAP with FLATMEM
Virtual memory map was intended to avoid wasting memory on the memory map
on systems with large holes in the physical memory layout. Long ago it been
superseded first by DISCONTIGMEM and then by SPARSEMEM. Moreover,
SPARSEMEM_VMEMMAP provide the same functionality in much more portable way.

As the first step to removing the VIRTUAL_MEM_MAP forbid it's usage with
FLATMEM and panic on systems with large holes in the physical memory
layout that try to run FLATMEM kernels.

Mike Rapoport 03e92a5e09 ia64: remove custom __early_pfn_to_nid()
The ia64 implementation of __early_pfn_to_nid() essentially relies on the
same data as the generic implementation.

The correspondence between memory ranges and nodes is set in memblock
during early memory initialization in register_active_ranges() function.

The initialization of sparsemem that requires early_pfn_to_nid() happens
later and it can use the memblock information like the other architectures.

Mike Rapoport 36d40290c8 alpha: switch from DISCONTIGMEM to SPARSEMEM
Patch series "arch, mm: deprecate DISCONTIGMEM", v2.

It's been a while since DISCONTIGMEM is generally considered deprecated,
but it is still used by four architectures.  This set replaces
DISCONTIGMEM with a different way to handle holes in the memory map and
marks DISCONTIGMEM configuration as BROKEN in Kconfigs of these
architectures with the intention to completely remove it in several
releases.

While for 64-bit alpha and ia64 the switch to SPARSEMEM is quite obvious
and was a matter of moving some bits around, for smaller 32-bit arc and
m68k SPARSEMEM is not necessarily the best thing to do.

On 32-bit machines SPARSEMEM would require large sections to make section
index fit in the page flags, but larger sections mean that more memory is
wasted for unused memory map.

Besides, pfn_to_page() and page_to_pfn() become less efficient, at least
on arc.

So I've decided to generalize arm's approach for freeing of unused parts
of the memory map with FLATMEM and enable it for both arc and m68k.  The
details are in the description of patches 10 (arc) and 13 (m68k).

This patch (of 13):

Enable SPARSEMEM support on alpha and deprecate DISCONTIGMEM.

The required changes are mostly around moving duplicated definitions of
page access and address conversion macros to a common place and making sure
they are available for all memory models.

The DISCONTINGMEM support is marked as BROKEN an will be removed in a
couple of releases.

Don't allow splitting of vm_special_mapping's.  It affects vdso/vvar
areas.  Uprobes have only one page in xol_area so they aren't affected.

Those restrictions were enforced by checks in .mremap() callbacks.
