Linus Torvalds 4c4a5c99af ARM: SoC: late updates
This is some material that we picked up into our tree late. Most of it
 are smaller fixes and additions, some defconfig updates due to recent
 development, etc.
 
 Code-wise the largest portion is a series of PM updates for the at91
 platform, and those have been in linux-next a while through the at91
 tree before we picked them up.

Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm

Pull ARM updates from Russell King:
 "ARM development updates:

   - more unified assembly conversions for clang

   - drop obsolete -mauto-it assembler option

   - remove arm_memory_present in preference to the generic version

   - remove unused asm/limits.h header

   - vdso linker update

  We tried to make the assembler warn if unified syntax was not used,
  but unfortunately older versions of GCC warn, so the commit had to be
  reverted"

Russell King b752bb405a Revert "ARM: 8846/1: warn if divided syntax assembler is used"
This reverts commit e8c24bbda7.

GCC 4.7, which is still permitted, emits code using the original
syntax.  This means we end up with lots of assembler warnings when
building with a currently-supported version of gcc.

Revert the commit (with fixups to keep the follow-on -mauto-it
change) to avoid these warnings.

Stephen Boyd 62e59c4e69 clk: Remove io.h from clk-provider.h
Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.

I also reordered a couple includes when they weren't alphabetical and

that driver doesn't use clk consumer APIs.

Masahiro Yamada 2e0168a714 ARM: mark setup_machine_tags() stub as __init __noreturn
This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common
place.  We need to eliminate potential issues beforehand.

If it is enabled for arm, Clang build results in the following modpost
warning:

  WARNING: vmlinux.o(.text+0x1124): Section mismatch in reference from the function setup_machine_tags() to the function .init.text:early_print()
  The function setup_machine_tags() references the function __init early_print().
  This is often because setup_machine_tags lacks a __init annotation or the annotation of early_print is wrong.

Arnd Bergmann be167862ae ARM: prevent tracing IPI_CPU_BACKTRACE
Patch series "compiler: allow all arches to enable
CONFIG_OPTIMIZE_INLINING", v3.

This patch (of 11):

When function tracing for IPIs is enabled, we get a warning for an
overflow of the ipi_types array with the IPI_CPU_BACKTRACE type as
triggered by raise_nmi():

  arch/arm/kernel/smp.c: In function 'raise_nmi':
  arch/arm/kernel/smp.c:489:2: error: array subscript is above array bounds [-Werror=array-bounds]
    trace_ipi_raise(target, ipi_types[ipinr]);

This is a correct warning as we actually overflow the array here.

This patch raise_nmi() to call __smp_cross_call() instead of
smp_cross_call(), to avoid calling into ftrace.  For clarification, I'm
also adding a two new code comments describing how this one is special.

The warning appears to have shown up after commit e7273ff49a ("ARM:
8488/1: Make IPI_CPU_BACKTRACE a "non-secure" SGI"), which changed the
number assignment from '15' to '8', but as far as I can tell has existed
since the IPI tracepoints were first introduced.  If we decide to
backport this patch to stable kernels, we probably need to backport
e7273ff49a as well.

[yamada.masahiro@socionext.com: rebase on v5.1-rc1]

Mike Rapoport 350e88bad4 mm: memblock: make keeping memblock memory opt-in rather than opt-out
Most architectures do not need the memblock memory after the page
allocator is initialized, but only few enable ARCH_DISCARD_MEMBLOCK in the
arch Kconfig.

Replacing ARCH_DISCARD_MEMBLOCK with ARCH_KEEP_MEMBLOCK and inverting the
logic makes it clear which architectures actually use memblock after
system initialization and skips the necessity to add ARCH_DISCARD_MEMBLOCK
to the architectures that are still missing that option.

Linus Torvalds 8148c17b17 This is the bulk of the GPIO changes for the v5.2 kernel cycle:
Core changes:
 - The gpiolib MMIO driver has been enhanced to handle two direction
   registers, i.e. one register to set lines as input and one register
   to set lines as output. It turns out some silicon engineer thinks
   the ability to configure a line as input and output at the same
   time makes sense, this can be debated but includes a lot of analog
   electronics reasoning, and the registers are there and need to
   be handled consistently. Unsurprisingly, we enforce the lines to
   be either inputs or outputs in such schemes.
 - Send in the proper argument value to .set_config() dispatched to
   the pin control subsystem. Nobody used it before, now someone
   does, so fix it to work as expected.
 - The ACPI gpiolib portions can now handle pin bias setting (pull up
   or pull down). This has been in the ACPI spec for years and we
   finally have it properly integrated with Linux GPIOs. It was based
   on an observation from Andy Schevchenko that Thomas Petazzoni's
   changes to the core for biasing the PCA950x GPIO expander actually
   happen to fit hand-in-glove with what the ACPI core needed.
   Such nice synergies happen sometimes.
 
 New drivers:
 - A new driver for the Mellanox BlueField GPIO controller. This is
   using 64bit MMIO registers and can configure lines as inputs
   and outputs at the same time and after improving the MMIO library
   we handle it just fine. Interesting.
 - A new IXP4xx proper gpiochip driver with hierarchical interrupts
   should be coming in from the ARM SoC tree as well.
 
 Driver enhancements:
 - The PCA053x driver handles the CAT9554 GPIO expander.
 - The PCA053x driver handles the NXP PCAL6416 GPIO expander.
 - Wake-up support on PCA053x GPIO lines.
 - OMAP now does a nice asynchronous IRQ handling on wake-ups by
   letting everything wake up on edges, and this makes runtime PM
   work as expected too.
 
 Misc:
 - Several cleanups such as devres fixes.
 - Get rid of some languager comstructs that cause problems when
   compiling with LLVMs clang.
 - Documentation review and update.

Viresh Kumar df24014abe cpufreq: Call transition notifier only once for each policy
Currently, the notifiers are called once for each CPU of the policy->cpus
cpumask. It would be more optimal if the notifier can be called only
once and all the relevant information be provided to it. Out of the 23
drivers that register for the transition notifiers today, only 4 of them
do per-cpu updates and the callback for the rest can be called only once
for the policy without any impact.

This would also avoid multiple function calls to the notifier callbacks
and reduce multiple iterations of notifier core's code (which does
locking as well).

This patch adds pointer to the cpufreq policy to the struct
cpufreq_freqs, so the notifier callback has all the information
available to it with a single call. The five drivers which perform
per-cpu updates are updated to use the cpufreq policy. The freqs->cpu
field is redundant now and is removed.

Linus Torvalds ea5aee6d97 We have a couple new features and changes in the core clk framework this time
around because we've finally gotten around to fixing some long standing issues.
 There's still work to do though, so this PR is largely laying down the
 foundation for all the driver changes to come in the next merge window.
 
 The first problem we're alleviating is how parents of clks are specified. With
 the new method, we should see lots of drivers migrate away from the current
 design of string comparisons on the entire clk tree to a more direct method
 where they can use clk_hw pointers or more localized names specified in DT or
 via clkdev. This should reduce our reliance on string comparisons for all the
 topology description logic that we've been using for years and hopefully speed
 some things up while avoiding problems we have with generating clk names.
 
 Beyond that we also got rid of the CLK_IS_BASIC flag because it wasn't really
 helping anyone and we introduced big-endian versions of the basic clk types so
 that we can get rid of clk_{readl,writel}(). Both of these are things that
 driver developers have tried to use over the years that I typically bat away
 during code reviews because they're not useful. It's great to see these two
 things go away so maintainers can save time not worrying about these things.
 
 On the driver side we got the usual collection of new SoC support and
 non-critical fixes and updates to existing code. The big topics that stand out
 are the new driver support for Mediatek MT8183 and MT8516 SoCs, Amlogic Meson8b
 and G12a SoCs, and the SiFive FU540 SoC. The other patches in the driver pile
 are mostly fixes for things that are being used for the first time or additions
 for clks that couldn't be tested before because there wasn't a consumer driver
 that exercised them. Details are below and also in the sub-maintainer tags.
 
 Core:
  - Remove clk_readl() and introduce BE versions of basic clk types
  - Rewrite how clk parents can be specified to allow DT/clkdev lookups
  - Removal of the CLK_IS_BASIC clk flag
  - Framework documentation updates and fixes
 
 New Drivers:
  - Support for STM32F769
  - AT91 sam9x60 PMC support
  - SiFive FU540 PRCI and PLL support
  - Qualcomm QCS404 CDSP clk support
  - Qualcomm QCS404 Turing clk support
  - Mediatek MT8183 clock support
  - Mediatek MT8516 clock support
  - Milbeaut M10V clk controller support
  - Support for Cirrus Logic Lochnagar clks
 
 Updates:
  - Rework AT91 sckc DT bindings
  - Fix slow RC oscillator issue on sama5d3
  - Mark UFS clk as critical on Hi-Silicon hi3660 SoCs
  - Various static analysis fixes/finds and const markings
  - Video Engine (ECLK) support on Aspeed SoCs
  - Xilinx ZynqMP Versal platform support
  - Convert Xilinx ZynqMP driver to be struct oriented
  - Fixes for Rockchip rk3328 and rk3288 SoCs
  - Sub-type for Rockchip SoCs where mux and divider aren't a single register
  - Remove SNVS clock from i.MX7UPL clock driver and bindings
  - Improve i.MX5 clock driver for i.MX50 support
  - Addition of ADC clock definition for Exynos 5410 SoC (Odroid XU)
  - Export a new clock for the MBUS controller on the A13
  - Allwinner H6 fixes to support a finer clocking of the video and VPU engines
  - Add g12a support in the Amlogic axg audio clock controller
  - Add missing PCI USB clock on Rensas RZ/N1
  - Add Z2 (Cortex-A53) clocks on Rensas R-Car E3 and RZ/G2E
  - A new helper DIV64_U64_ROUND_CLOSEST() in <linux/math64.h>
  - VPU and Video Decoder clocks on Amlogic Meson8b
  - Finally remove the wrong ABP Meson8b clock id
  - Add Video Decoder, PCIe PLL, and CPU Clocks on Amlogic G12A
  - Re-expose SAR_ADC_SEL and CTS_OSCIN on Amlogic G12A AO clock controller
  - Un-expose some Amlogic AXG-Audio input clocks IDs

Pull audit updates from Paul Moore:
 "We've got a reasonably broad set of audit patches for the v5.2 merge
  window, the highlights are below:

   - The biggest change, and the source of all the arch/* changes, is
     the patchset from Dmitry to help enable some of the work he is
     doing around PTRACE_GET_SYSCALL_INFO.

     To be honest, including this in the audit tree is a bit of a
     stretch, but it does help move audit a little further along towards
     proper syscall auditing for all arches, and everyone else seemed to
     agree that audit was a "good" spot for this to land (or maybe they
     just didn't want to merge it? dunno.).

   - We can now audit time/NTP adjustments.

   - We continue the work to connect associated audit records into a
     single event"

Linus Torvalds e0dccbdf5a Staging / IIO driver patches for 5.2-rc1
Here is the big staging and iio driver update for 5.2-rc1.
 
 Lots of tiny fixes all over the staging and IIO driver trees here, along
 with some new IIO drivers.
 
 Also we ended up deleting two drivers, making this pull request remove a
 few hundred thousand lines of code, always a nice thing to see.  Both of
 the drivers removed have been replaced with "real" drivers in their
 various subsystem directories, and they will be coming to you from those
 locations during this merge window.
 
 There are some core vt/selection changes in here, that was due to some
 cleanups needed for the speakup fixes.  Those have all been acked by the
 various subsystem maintainers (i.e. me), so those are ok.
 
 We also added a few new drivers, for some odd hardware, giving new
 developers plenty to work on with basic coding style cleanups to come in
 the near future.
 
 Other than that, nothing unusual here.
 
 All of these have been in linux-next for a while with no reported
 issues, other than an odd gcc warning for one of the new drivers that
 should be fixed up soon.

Merge tag 'pidfd-v5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull pidfd updates from Christian Brauner:
 "This patchset makes it possible to retrieve pidfds at process creation
  time by introducing the new flag CLONE_PIDFD to the clone() system
  call. Linus originally suggested to implement this as a new flag to
  clone() instead of making it a separate system call.

  After a thorough review from Oleg CLONE_PIDFD returns pidfds in the
  parent_tidptr argument. This means we can give back the associated pid
  and the pidfd at the same time. Access to process metadata information
  thus becomes rather trivial.

  As has been agreed, CLONE_PIDFD creates file descriptors based on
  anonymous inodes similar to the new mount api. They are made
  unconditional by this patchset as they are now needed by core kernel
  code (vfs, pidfd) even more than they already were before (timerfd,
  signalfd, io_uring, epoll etc.). The core patchset is rather small.
  The bulky looking changelist is caused by David's very simple changes
  to Kconfig to make anon inodes unconditional.

  A pidfd comes with additional information in fdinfo if the kernel
  supports procfs. The fdinfo file contains the pid of the process in
  the callers pid namespace in the same format as the procfs status
  file, i.e. "Pid:\t%d".

  To remove worries about missing metadata access this patchset comes
  with a sample/test program that illustrates how a combination of
  CLONE_PIDFD and pidfd_send_signal() can be used to gain race-free
  access to process metadata through /proc/<pid>.

  Further work based on this patchset has been done by Joel. His work
  makes pidfds pollable. It finished too late for this merge window. I
  would prefer to have it sitting in linux-next for a while and send it
  for inclusion during the 5.3 merge window"

Linus Torvalds 9bff9dfc51 spi: Updates for v5.2
One small feature was added this release but the bulk of the diffstat
 and the changelog comes from the fact that several older drivers got
 some fairly hefty reworks and a couple of new drivers were added:
 
  - Support for detailed control of timing around chip selects from
    Sowjanya Komatineni.
  - A big set of fixes and imrovements for the Tegra114 driver from
    Sowjanya Komatineni.
  - A big simplification of the GPIO driver from Andrey Smirnov.
  - DMA support and fixes for the Freescale LPSPI driver from Clark Wang.
  - Fixes and optimizations for the bcm2835aux from Martin Sparl.

Merge tag 'spi-v5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "One small feature was added this release but the bulk of the diffstat
  and the changelog comes from the fact that several older drivers got
  some fairly hefty reworks and a couple of new drivers were added:

   - Support for detailed control of timing around chip selects from
     Sowjanya Komatineni.

   - A big set of fixes and imrovements for the Tegra114 driver from
     Sowjanya Komatineni.

   - A big simplification of the GPIO driver from Andrey Smirnov.

   - DMA support and fixes for the Freescale LPSPI driver from Clark
     Wang.

   - Fixes and optimizations for the bcm2835aux from Martin Sparl.

   - New drivers for Mediatek MT7621 (graduated from staging) and Zynq
     QSPI"

[ This is a so-called "evil merge" that additionally removes a warning
  due to an unused variable 'i' introduced by commit 1dfbf334f1 ("spi:
  ep93xx: Convert to use CS GPIO descriptors")     - Linus ]
