Joshua Hunt a1ee1932aa watchdog: don't run proc_watchdog_update if new value is same as old
While working on a script to restore all sysctl params before a series of
tests I found that writing any value into the
/proc/sys/kernel/{nmi_watchdog,soft_watchdog,watchdog,watchdog_thresh}
causes them to call proc_watchdog_update().

  NMI watchdog: enabled on all CPUs, permanently consumes one hw-PMU counter.
  NMI watchdog: enabled on all CPUs, permanently consumes one hw-PMU counter.
  NMI watchdog: enabled on all CPUs, permanently consumes one hw-PMU counter.
  NMI watchdog: enabled on all CPUs, permanently consumes one hw-PMU counter.

There doesn't appear to be a reason for doing this work every time a write
occurs, so only do it when the values change.

Aaro Koskinen 4c11e554fb drivers/firmware/broadcom/bcm47xx_nvram.c: fix incorrect __ioread32_copy
Commit 1f330c3279 ("drivers/firmware/broadcom/bcm47xx_nvram.c: use
__ioread32_copy() instead of open-coding") switched to use a generic
copy function, but failed to notice that the header pointer is updated
between the two copies, resulting in bogus data being copied in the
latter one.  Fix by keeping the old header pointer.

The patch fixes totally broken networking on WRT54GL router (both LAN and
WLAN interfaces fail to probe).

Luis R. Rodriguez b0f84ac352 ia64: define ioremap_uc()
All architectures now need ioremap_uc(), ia64 seems defines this already
through its ioremap_nocache() and it already ensures it *only* uses UC.

This is needed since v4.3 to complete an allyesconfig compile on ia64,
there were others archs that needed this, and this one seems to have
fallen through the cracks.

Linus Torvalds 45cb5230f8 VFIO updates for v4.6-rc1
Various enablers for assignment of Intel graphics devices and future
 support of vGPU devices (Alex Williamson).  This includes
 
  - Handling the vfio type1 interface as an API rather than a specific
    implementation, allowing multiple type1 providers.
 
  - Capability chains, similar to PCI device capabilities, that allow
    extending ioctls.  Extensions here include device specific regions
    and sparse mmap descriptions.  The former is used to expose non-PCI
    regions for IGD, including the OpRegion (particularly the Video
    BIOS Table), and read only PCI config access to the host and LPC
    bridge as drivers often depend on identifying those devices.
    Sparse mmaps here are used to describe the MSIx vector table,
    which vfio has always protected from mmap, but never had an API to
    explicitly define that protection.  In future vGPU support this is
    expected to allow the description of PCI BARs that may mix direct
    access and emulated access within a single region.
 
  - The ability to expose the shadow ROM as an option ROM as IGD use
    cases may rely on the ROM even though the physical device does not
    make use of a PCI option ROM BAR.

Add a new pseudo-board, within the existing SH boards/machine-vectors
framework, which does not represent any actual hardware but instead
requires all hardware to be described by the device tree blob provided
by the boot loader. Changes made are thus non-invasive and do not risk
breaking support for legacy boards.

New hardware, including the open-hardware J2 and associated SoC
devices, will use device free from the outset. Legacy SH boards can
transition to device tree once all their hardware has device tree
bindings, driver support for device tree, and a dts file for the
board.

It is intented that, once all boards are supported in the new
framework, the existing machine-vectors framework should be removed
and the new device tree setup code integrated directly.

Rich Felker 45624ac389 sh: remove arch-specific localtimer and use generic one
The code being removed was copied from arm, where the corresponding
code was removed in 2013. The only functional change should be that
the rating of the dummy local timer changes from 400 to 100.

Rich Felker 3623d13821 sh: provide unified syscall trap compatible with all SH models
Historically SH-2 Linux (and originally uClinux) used a syscall
calling convention incompatible with the established SH-3/4 Linux ABI.
This choice was made because the trap range used by the existing ABI,
0x10-0x17, overlaps with the hardware exception/interrupt trap range
reserved by SH-2, and in particular, with the SH-2A divide-by-zero and
division-overflow exceptions.

Despite the documented syscall convention using the low bits of the
trap number to signal the number of arguments the kernel should
expect, no version of the kernel has ever used this information, nor
is it useful; all of the registers need to be saved anyway. Therefore,
it is possible to pick a new trap number, 0x1f, that is both supported
by all existing SH-3/4 kernels and unassigned as a hardware trap in
the SH-2 range. This makes it possible to produce SH-2 application
binaries that are forwards-compatible with running on SH-3/4 kernels
and to treat SH as a unified platform with varying ISA support levels
rather than multiple gratuitously-incompatible platforms.

This patch adjusts the range checking SH-2 and SH-2A kernels make for
the syscall trap to accept the range 0x1f-0x2f rather than just
0x20-0x2f. As a result, trap 0x1f now acts as a syscall for all SH
models.

Stephen Boyd ea17c9d868 sh: Use generic clkdev.h header
The generic header file is almost equivalent to the SH one. The
only difference is that the SH one supports allocating clkdev
lookups early using bootmem allocators instead of the slabs. From
what I can tell using visual inspection, the slab is initialized
before any clkdev allocation is made under arch/sh. So let's
remove the arch specific clkdev.h header and use the generic one
instead.

Takashi Iwai 222bde0388 ALSA: hda - Fix mutex deadlock at HDMI/DP hotplug
The recent change in HD-audio HDMI/DP codec driver for allowing the
dynamic PCM binding introduced a new spec->pcm_mutex.  One of the
protected area by this mutex is hdmi_present_sense().  As reported by
Intel CI tests, unfortunately, the new mutex causes a deadlock when
the hotplug/unplug is triggered during the codec is in runtime
suspend.  The buggy code path is like the following:

  hdmi_unsol_event() -> ...
    -> hdmi_present_sense()
==>     ** here taking pcm_mutex
      -> hdmi_present_sense_via_verbs()
        -> snd_hda_power_up_pm() -> ... (runtime resume calls)
          -> generic_hdmi_resume()
            -> hdmi_present_sense()
==>           ** here taking pcm_mutex again!

As we can see here, the problem is that the mutex is taken before
snd_hda_power_up_pm() call that triggers the runtime resume.  That is,
the obvious solution is to move the power up/down call outside the
mutex; it is exactly what this patch provides.

The patch also clarifies why this bug wasn't caught beforehand.  We
used to have the i915 audio component for hotplug for all Intel chips,
and in that code path, there is no power up required but the
information is taken directly from the graphics side.  However, we
recently switched back to the old method for some old Intel chips due
to regressions, and now the deadlock issue is surfaced.

Remove the livepatch module notifier in favor of directly enabling and
disabling patches to modules in the module loader. Hard-coding the
function calls ensures that ftrace_module_enable() is run before
klp_module_coming() during module load, and that klp_module_going() is
run before ftrace_release_mod() during module unload. This way, ftrace
and livepatch code is run in the correct order during the module
load/unload sequence without dependence on the module notifier call chain.

Put all actions in complete_formation() that are performed after
module->state is set to MODULE_STATE_COMING into a separate function
prepare_coming_module(). This split prepares for the removal of the
livepatch module notifiers in favor of hard-coding function calls to
klp_module_{coming,going} in the module loader.

The complete_formation -> prepare_coming_module split will also make error
handling easier since we can jump to the appropriate error label to do any
module GOING cleanup after all the COMING-actions have completed.

Linus Torvalds 8759957b77 libnvdimm for 4.6
1/ Asynchronous address range scrub:
 Given the capacities of next generation persistent memory devices a
 scrub operation to find all poison may take 10s of seconds.  We want
 this scrub work to be done asynchronously with the rest of system
 initialization, so we move it out of line from the NFIT probing, i.e.
 acpi_nfit_add().
 
 2/ Clear poison:
 ACPI 6.1 introduces the ability to send "clear error" commands to the
 ACPI0012:00 device representing the root of an "nvdimm bus".  Similar to
 relocating a bad block on a disk, this support clears media errors in
 response to a write.
 
 3/ Persistent memory resource tracking:
 A persistent memory range may be designated as simply "reserved" by
 platform firmware in the efi/e820 memory map.  Later when the NFIT
 driver loads it discovers that the range is "Persistent Memory".  The
 NFIT bus driver inserts a resource to advertise that "persistent"
 attribute in the system resource tree for /proc/iomem and
 kernel-internal usages.
 
 4/ Miscellaneous cleanups and fixes:
 Workaround section misaligned pmem ranges when allocating a struct page
 memmap, fix handling of the read-only case in the ioctl path, and clean
 up block device major number allocation.

Linus Torvalds 6968e6f832 - Most attention this cycle went to optimizing blk-mq request-based DM
(dm-mq) that is used exclussively by DM multipath.
 
   - A stable fix for dm-mq that eliminates excessive context switching
     offers the biggest performance improvement (for both IOPs and
     throughput).
 
   - But more work is needed, during the next cycle, to reduce spinlock
     contention in DM multipath on large NUMA systems.
 
 - A stable fix for a NULL pointer seen when DM stats is enabled on a DM
   multipath device that must requeue an IO due to path failure.
 
 - A stable fix for DM snapshot to disallow the COW and origin devices
   from being identical.  This amounts to graceful failure in the face of
   userspace error because these devices shouldn't ever be identical.
 
 - Stable fixes for DM cache and DM thin provisioning to address crashes
   seen if/when their respective metadata device experiences failures
   that cause the transition to 'fail_io' mode.
 
 - The DM cache 'mq' policy is now an alias for the 'smq' policy.  The
   'smq' policy proved to be consistently better than 'mq'.  As such
   'mq', with all its complex user-facing tunables, has been eliminated.
 
 - Improve DM thin provisioning to consistently return -ENOSPC once the
   thin-pool's data volume is out of space.
 
 - Improve DM core to properly handle error propagation if
   bio_integrity_clone() fails in clone_bio().

David Daney b7d3e3d3d2 net: thunderx: Don't leak phy device references on -EPROBE_DEFER condition.
It is possible, although unlikely, that probing will find the
phy_device for the first LMAC of a thunder BGX device, but then need
to fail with -EPROBE_DEFER on a subsequent LMAC.  In this case, we
need to call put_device() on each of the phy_devices that were
obtained, but will be unused due to returning -EPROBE_DEFER.

Also, since we can break out of the probing loop early, we need to
explicitly call of_node_put() outside of the loop.

Locking ppp_mutex must be done before dereferencing file->private_data,
otherwise it could be modified before ppp_unattached_ioctl() takes the
lock. This could lead ppp_unattached_ioctl() to override ->private_data,
thus leaking reference to the ppp_file previously pointed to.

v2: lock all ppp_ioctl() instead of just checking private_data in
    ppp_unattached_ioctl(), to avoid ambiguous behaviour.

Hi Rob, David:
PATCH[1/9-2/9]: ====>
net: arc_emac: make the rockchip emac document more compatible
net: arc_emac: add phy reset is optional for device tree

The patches change the rockchip emac document for more compatible and
Add the phy reset property for document.

Hi David
PATCH[3/9]: ====>
net: arc_emac: support the phy reset for emac driver

The emac didn't work on kylin board since in some case the clocks parent changed.
The kylin hardware connects the phy reset pin, we should use it with real world.
As the previous patch discuss on https://patchwork.kernel.org/patch/8186801/

And as sergei/Heiko suggestions on
https://patchwork.kernel.org/patch/8564571/

Hi David
PATCH[4/9]: ====>
net: arc: trivial: cleanup the emac driver

The first time to look the emac drivers, I think that have to cleanup the drivers with scripts.
Although it's the trivial things, in order to be more read.

- Add the Cc people
- As Sergei comments, the original name is better, so
  %s/reset-gpios/phy-reset-gpios
- Add the Cc people.
- Caused the build error since the missing include head file.
- %s/reset/phy-reset to match the device tree.
- Add the Cc people
- Add the Cc people.
- Add the Cc people.
- Add the Cc people.
- Add the Cc people.
- Add the Cc people.
- rename reset-gpio to phy-reset-gpios.
- change the commit.
- remove the pcfg_output_high, that's really not needed for emac.
- Add the Cc people.
- Fixes the 'zhengxing' to 'Xing Zheng'.

Changes in v2:
- change the commit and remove the repeat the name 'rockchip'.
- %s/phy-reset-gpios/reset-gpios
- As the pervious version, Sergei and Heiko comments on
  https://patchwork.kernel.org/patch/8564571/.
- Nevermind, add signed-off since Heiko the original patch,
  refer the Heiko's test patch on
  a943c58878
  :)
- As the robot notice the build error since overflow in implicit
  constant conversion.
- rename phy-reset-gpio to reset-gpios.

Xing Zheng af671e7bd9 ARM: dts: rockchip: add to support emac for rk3036 SoCs
This patch adds the emac device node for rk3036 SoCs.
We need to let mac clock under the DPLL which is able to provide
the accurate 50MHz what mac_ref need, since that will cause some
unstable things if the cpufreq is working.

Heiko Stuebner 2c6fae2501 clk: rockchip: associate SCLK_MAC_PLL and disable reparenting on rk3036
The emac needs constant and very specific rate but the possible PLL-sources
are very limited, so we expect the PLL source to be set manually on per
board and don't want it to get changed in an automatic way later.
So add the necessary clock-id and disable reparenting on set_rate calls.

Xing Zheng f7e180222b clk: rockchip: add clock-id for rk3036 emac pll source clock
Suitable PLLs for the emac on the rk3036 are difficult to find
and one of them is the (continuously changing) APLL. So in most
cases it will be necessary to select a PLL manually.
So add a clock-id for it.

Caesar Wang 663713eb47 net: arc: trivial: cleanup the emac driver
This patch will make the driver more readability

The emac has the error and warnings if you run
'scripts/checkpatch.pl -f --subjective xxx' to check.

Let's clean up such trivial details.

Caesar Wang 1bddd96cba net: arc_emac: support the phy reset for emac driver
This patch adds to support the emac phy reset.

Different boards may require different phy reset duration. Add property
phy-reset-duration for emac driver, so that the boards that need
a longer reset duration can specify it in their device tree.

Caesar Wang 8700eee627 net: arc_emac: add phy reset is optional for device tree
This patch adds the following property for arc_emac.

1) phy-reset-gpios:
The phy-reset-gpio is an optional property for arc emac device tree boot.
Change the binding document to match the driver code.

2) phy-reset-duration:
Different boards may require different phy reset duration. Add property
phy-reset-duration for device tree probe, so that the boards that need
a longer reset duration can specify it in their device tree.

Anyway, we can add the above property for arc emac.
