The memblock_alloc_base() function tries to allocate a memory up to the
limit specified by its max_addr parameter and panics if the allocation
fails. Replace its usage with memblock_phys_alloc_range() and make the
callers check the return value and panic in case of error.

The __memblock_alloc_base() function tries to allocate a memory up to
the limit specified by its max_addr parameter. Depending on the value
of this parameter, the __memblock_alloc_base() can is replaced with the
appropriate memblock_phys_alloc*() variant.

The memblock_phys_alloc_try_nid() function tries to allocate memory from
the requested node and then falls back to allocation from any node in
the system. The memblock_alloc_base() fallback used by this function
panics if the allocation fails.
Replace the memblock_alloc_base() fallback with the direct call to
memblock_alloc_range_nid() and update the memblock_phys_alloc_try_nid()
callers to check the returned value and panic in case of error.

Since only the virtual address of allocated blocks is used, lets use
functions returning directly virtual address.
Those functions have the advantage of also zeroing the block.

Patch series "Refine memblock API", v2.
Current memblock API is quite extensive and, which is more annoying,
duplicated. Except the low-level functions that allow searching for a
free memory region and marking it as reserved, memblock provides three
(well, two and a half) sets of functions to allocate memory.
There are several overlapping functions that return a physical address
and there are functions that return virtual address. Those that return
the virtual address may also clear the allocated memory. And, on top of
all that, some allocators panic and some return NULL in case of error.
This set tries to reduce the mess, and trim down the amount of memblock
allocation methods.
Patches 1-10 consolidate the functions that return physical address of
the allocated memory
Patches 11-13 are some trivial cleanups
Patches 14-19 add checks for the return value of memblock_alloc*() and
panics in case of errors. The patches 14-18 include some minor
refactoring to have better readability of the resulting code and patch
19 is a mechanical addition of
if (!ptr)
panic();
after memblock_alloc*() calls.
And, finally, patches 20 and 21 remove panic() calls memblock and
_nopanic variants from memblock.
This patch (of 21):
The allocation of the page tables memory in openrics uses
memblock_phys_alloc() and then converts the returned physical address to
virtual one. Use memblock_alloc_raw() and add a panic() if the
allocation fails.

Pull integrity updates from James Morris:
"Mimi Zohar says:
'Linux 5.0 introduced the platform keyring to allow verifying the IMA
kexec kernel image signature using the pre-boot keys. This pull
request similarly makes keys on the platform keyring accessible for
verifying the PE kernel image signature.
Also included in this pull request is a new IMA hook that tags tmp
files, in policy, indicating the file hash needs to be calculated.
The remaining patches are cleanup'"

First: Ted, Jaegeuk, and I have decided to add me as a co-maintainer for
fscrypt, and we're now using a shared git tree. So we've updated
MAINTAINERS accordingly, and I'm doing the pull request this time.
The actual changes for v5.1 are:
- Remove the fs-specific kconfig options like CONFIG_EXT4_ENCRYPTION and
make fscrypt support for all fscrypt-capable filesystems be controlled
by CONFIG_FS_ENCRYPTION, similar to how CONFIG_QUOTA works.
- Improve error code for rename() and link() into encrypted directories.
- Various cleanups.

The client IMC events are freerunning counters. They still use the
old event encoding format (0x1 for data_read and 0x2 for data write).
The counter bit width is calculated by common code, which assume that
the standard encoding format is used for the freerunning counters.
Error bit width information is calculated.
The patch intends to convert the old client IMC event encoding to the
standard encoding format.
Current common code uses event->attr.config which directly copy from
user space. We should not implicitly modify it for a converted event.
The event->hw.config is used to replace the event->attr.config in
common code.
For client IMC events, the event->attr.config is used to calculate a
converted event with standard encoding format in the custom
event_init(). The converted event is stored in event->hw.config.
For other events of freerunning counters, they already use the standard
encoding format. The same value as event->attr.config is assigned to
event->hw.config in common event_init().

Pull io_uring IO interface from Jens Axboe:
"Second attempt at adding the io_uring interface.
Since the first one, we've added basic unit testing of the three
system calls, that resides in liburing like the other unit tests that
we have so far. It'll take a while to get full coverage of it, but
we're working towards it. I've also added two basic test programs to
tools/io_uring. One uses the raw interface and has support for all the
various features that io_uring supports outside of standard IO, like
fixed files, fixed IO buffers, and polled IO. The other uses the
liburing API, and is a simplified version of cp(1).
This adds support for a new IO interface, io_uring.
io_uring allows an application to communicate with the kernel through
two rings, the submission queue (SQ) and completion queue (CQ) ring.
This allows for very efficient handling of IOs, see the v5 posting for
some basic numbers:
https://lore.kernel.org/linux-block/20190116175003.17880-1-axboe@kernel.dk/
Outside of just efficiency, the interface is also flexible and
extendable, and allows for future use cases like the upcoming NVMe
key-value store API, networked IO, and so on. It also supports async
buffered IO, something that we've always failed to support in the
kernel.
Outside of basic IO features, it supports async polled IO as well.
This particular feature has already been tested at Facebook months ago
for flash storage boxes, with 25-33% improvements. It makes polled IO
actually useful for real world use cases, where even basic flash sees
a nice win in terms of efficiency, latency, and performance. These
boxes were IOPS bound before, now they are not.
This series adds three new system calls. One for setting up an
io_uring instance (io_uring_setup(2)), one for submitting/completing
IO (io_uring_enter(2)), and one for aux functions like registrating
file sets, buffers, etc (io_uring_register(2)). Through the help of
Arnd, I've coordinated the syscall numbers so merge on that front
should be painless.
Jon did a writeup of the interface a while back, which (except for
minor details that have been tweaked) is still accurate. Find that
here:
https://lwn.net/Articles/776703/
Huge thanks to Al Viro for helping getting the reference cycle code
correct, and to Jann Horn for his extensive reviews focused on both
security and bugs in general.
There's a userspace library that provides basic functionality for
applications that don't need or want to care about how to fiddle with
the rings directly. It has helpers to allow applications to easily set
up an io_uring instance, and submit/complete IO through it without
knowing about the intricacies of the rings. It also includes man pages
(thanks to Jeff Moyer), and will continue to grow support helper
functions and features as time progresses. Find it here:
git://git.kernel.dk/liburing
Fio has full support for the raw interface, both in the form of an IO
engine (io_uring), but also with a small test application (t/io_uring)
that can exercise and benchmark the interface"

Core changes:
- The big change this time around is the irqchip handling in
the qualcomm pin controllers, closely coupled with the
gpiochip. This rework, in a classic fall-between-the-chairs
fashion has been sidestepped for too long. The Qualcomm
IRQchips using the SPMI and SSBI transport mechanisms have
been rewritten to use hierarchical irqchip. This creates
the base from which I intend to gradually pull support for
hierarchical irqchips into the gpiolib irqchip helpers to
cut down on duplicate code. We have too many hacks in the
kernel because people have been working around the missing
hierarchical irqchip for years, and once it was there,
noone understood it for a while. We are now slowly adapting
to using it. This is why this pull requests include changes
to MFD, SPMI, IRQchip core and some ARM Device Trees
pertaining to the Qualcomm chip family. Since Qualcomm have
so many chips and such large deployments it is paramount
that this platform gets this right, and now it (hopefully)
does.
- Core support for pull-up and pull-down configuration, also
from the device tree. When a simple GPIO chip support a
"off or on" pull-up or pull-down resistor, we provide a
way to set this up using machine descriptors or device tree.
If more elaborate control of pull up/down (such as
resistance shunt setting) is required, drivers should be
phased over to use pin control. We do not yet provide a
userspace ABI for this pull up-down setting but I suspect
the makers are going to ask for it soon enough. PCA953x
is the first user of this new API.
- The GPIO mockup driver has been revamped after some
discussion improving the IRQ simulator in the process.
The idea is to make it possible to use the mockup for
both testing and virtual prototyping, e.g. when you do
not yet have a GPIO expander to play with but really
want to get something to develop code around before
hardware is available. It's neat. The blackbox testing
usecase is currently making its way into kernelci.
- ACPI GPIO core preserves non direction flags when updating
flags.
- A new device core helper for devm_platform_ioremap_resource()
is funneled through the GPIO tree with Greg's ACK.
New drivers:
- TQ-Systems QTMX86 GPIO controllers (using port-mapped
I/O)
- Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
- AMD G-Series PCH (Platform Controller Hub) GPIO driver.
- Fintek F81804 & F81966 subvariants.
- PCA953x now supports NXP PCAL6416.
Driver improvements:
- IRQ support on the Nintendo Wii (Hollywood) GPIO.
- get_direction() support for the MVEBU driver.
- Set the right output level on SAMA5D2.
- Drop the unused irq trigger setting on the Spreadtrum
driver.
- Wakeup support for PCA953x.

Since commit ad67b74d24 ("printk: hash addresses printed with %p"),
the virtual memory layout printed during boot up contains "ptrval"

Instead of changing the printing to "%px", and leaking virtual memory
layout information again, just remove the printing completely, cfr.

All interesting information (actual section sizes) is already printed by

Page fault handlers are supposed to return VM_FAULT codes, but some
drivers/file systems mistakenly return error numbers. Now that all
drivers/file systems have been converted to use the vm_fault_t return
type, change the type definition to no longer be compatible with 'int'.
By making it an unsigned int, the function prototype becomes
incompatible with a function which returns int. Sparse will detect any
attempts to return a value which is not a VM_FAULT code.
VM_FAULT_SET_HINDEX and VM_FAULT_GET_HINDEX values are changed to avoid
conflict with other VM_FAULT codes.

There are several early memory allocations in arch/ code that use
memblock_phys_alloc() to allocate memory, convert the returned physical
address to the virtual address and then set the allocated memory to
zero.
Exactly the same behaviour can be achieved simply by calling
memblock_alloc(): it allocates the memory in the same way as
memblock_phys_alloc(), then it performs the phys_to_virt() conversion
and clears the allocated memory.
Replace the longer sequence with a simpler call to memblock_alloc().

The pte_alloc_one_kernel() function allocates a page using
__get_free_page(GFP_KERNEL) when mm initialization is complete and
memblock_phys_alloc() on the earlier stages. The physical address of
the page allocated with memblock_phys_alloc() is converted to the
virtual address and in the both cases the allocated page is cleared
using clear_page().
The code is simplified by replacing __get_free_page() with
get_zeroed_page() and by replacing memblock_phys_alloc() with
memblock_alloc().

and then convert this address to the virtual one, use appropriate

There is a small functional change in the allocation of then
NODE_DATA(). Instead of panicing if the local allocation failed, the
non-local allocation attempt will be made.

Patch series "memblock: simplify several early memory allocation", v4.
These patches simplify some of the early memory allocations by replacing
usage of older memblock APIs with newer and shinier ones.
Quite a few places in the arch/ code allocated memory using a memblock
API that returns a physical address of the allocated area, then
converted this physical address to a virtual one and then used memset(0)
to clear the allocated range.
More recent memblock APIs do all the three steps in one call and their
usage simplifies the code.
It's important to note that regardless of API used, the core allocation
is nearly identical for any set of memblock allocators: first it tries
to find a free memory with all the constraints specified by the caller
and then falls back to the allocation with some or all constraints
disabled.
The first three patches perform the conversion of call sites that have
exact requirements for the node and the possible memory range.
The fourth patch is a bit one-off as it simplifies openrisc's
implementation of pte_alloc_one_kernel(), and not only the memblock
usage.
The fifth patch takes care of simpler cases when the allocation can be
satisfied with a simple call to memblock_alloc().
The sixth patch removes one-liner wrappers for memblock_alloc on arm and
unicore32, as suggested by Christoph.
This patch (of 6):
There are a several places that allocate memory using memblock APIs that
return a physical address, convert the returned address to the virtual
address and frequently also memset(0) the allocated range.
Update these places to use memblock allocators already returning a
virtual address. Use memblock functions that clear the allocated memory
instead of calling memset(0) where appropriate.
The calls to memblock_alloc_base() that were not followed by memset(0)
are replaced with memblock_alloc_try_nid_raw(). Since the latter does
not panic() when the allocation fails, the appropriate panic() calls are
added to the call sites.

together with fixes from Borislav Petkov"
* 'x86-boot-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/boot/compressed/64: Do not read legacy ROM on EFI system
x86/boot: Correct RSDP parsing with 32-bit EFI
x86/kexec: Fill in acpi_rsdp_addr from the first kernel
x86/boot: Fix randconfig build error due to MEMORY_HOTREMOVE
x86/boot: Fix cmdline_find_option() prototype visibility
x86/boot/KASLR: Limit KASLR to extract the kernel in immovable memory only
x86/boot: Parse SRAT table and count immovable memory regions
x86/boot: Early parse RSDP and save it in boot_params
x86/boot: Search for RSDP in memory
x86/boot: Search for RSDP in the EFI tables
x86/boot: Add "acpi_rsdp=" early parsing
x86/boot: Copy kstrtoull() to boot/string.c
x86/boot: Build the command line parsing code unconditionally
Notable changes:
- Enable THREAD_INFO_IN_TASK to move thread_info off the stack.
- A big series from Christoph reworking our DMA code to use more of the generic
infrastructure, as he said:
"This series switches the powerpc port to use the generic swiotlb and
noncoherent dma ops, and to use more generic code for the coherent direct
mapping, as well as removing a lot of dead code."
- Increase our vmalloc space to 512T with the Hash MMU on modern CPUs, allowing
us to support machines with larger amounts of total RAM or distance between
nodes.
- Two series from Christophe, one to optimise TLB miss handlers on 6xx, and
another to optimise the way STRICT_KERNEL_RWX is implemented on some 32-bit
CPUs.
- Support for KCOV coverage instrumentation which means we can run syzkaller
and discover even more bugs in our code.
And as always many clean-ups, reworks and minor fixes etc.

This contains the vast majority of the RISC-V patches for this merge
window. It includes:
* A handful of cleanups to our kernel prints, most of which are things I
should have caught the first time.
* We now provide an HWCAP that contains the ISA extensions that all
enabled processors support, as supposed to just looking at the first
enabled processor.
* We no longer spin forever waiting for all harts to boot.
* A fixmap implementation, which is coupled to some cleanups in our MM
code.
The only outstanding patches I know of right now are Vincent Chen's
patches to fix c.ebreak handling in the kernel, the v2 of which was
posted this morning. I'd like those in the MW, but I didn't want to
hold up everything else. The patch set is based on top of my last fixes
submission, but I've tested it with a conflict-free merge from v5.0.
I'm doing this rather than my "just go rebase everything" flow due to a
discussion with Linus, but if I misunderstood then just let me know and
I'll do something else. It's also the first time I've taken a PR into
my own tree, so let me know if I screwed that one up.
I've used my standard testing flow (QEMU in Fedora), but now that we're
starting to get the kernel in better shape I think it's time to impose
some more testing here -- specifically I'm going to require that patches
boot on the HiFive Unleashed because we're getting to the point where we
can actually expect that to work. I haven't done that for this tag, but
I'm going to do it for future ones.
I know the board is a bit expensive and not everyone has one, but if
I've sent you a free one and your patches break the boot then I'm going
to yell at you :). If you don't have one then please indicate how you
tested in your cover letter, and if you have a board then please add
your Tested-by to patches if they work for your testing flow.
