dc5fa46568 This is the bulk of pin control changes for the v5.5 kernel 
series:
 
 Core changes:
 
 - Avoid taking direct references to device tree-supplied
   device names: these may changed at runtime under certain
   circumstances to kstrdup them.
 
 GPIO related:
 
 - Work is ongoing to move to passing the irqchip along as a
   templated struct gpio_irq_chip when adding a standard
   gpiolib-based irqchip to a GPIO controller, a few patches
   in this cycle switches a few pin control drivers over to
   using this method.
 
 New hardware support:
 
 - Intel Lightning Mountain SoC pin controller and GPIO
   support, a first Intel platform to use device tree rather
   than ACPI to configure the system. News reports says that
   this SoC is a network processor.
 
 - Qualcomm MSM8976 and MSM8956
 
 - Qualcomm PMIC GPIO now also supports PM6150 and PM6150L
 
 - Qualcomm SPMI MPP and SPMI GPIO for PM8950 and PMI8950
 
 - Rockchip RK3308
 
 - Renesas R8A77961
 
 - Allwinner Meson-A1
 
 Driver improvements:
 
 - get_multiple and set_multiple support for the AT91-PIO4 driver.
 
 - Convert Qualcomm SSBI GPIO to use the hierarchical IRQ helpers
   in the GPIOlib irqchip.

Merge tag 'pinctrl-v5.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for v5.5.

  It is pretty much business as usual, the most interesting thing I
  think is the pin controller for a new Intel chip called Lightning
  Mountain, which is according to news reports some kind of embedded
  network processor and what is surprising about it is that Intel have
  decided to use device tree to describe the system rather than ACPI
  that they have traditionally favored.

  Core changes:

   - Avoid taking direct references to device tree-supplied device
     names: these may changed at runtime under certain circumstances to
     kstrdup them.

  GPIO related:

   - Work is ongoing to move to passing the irqchip along as a templated
     struct gpio_irq_chip when adding a standard gpiolib-based irqchip
     to a GPIO controller, a few patches in this cycle switches a few
     pin control drivers over to using this method.

3f1b210a7f sound updates for 5.5-rc1 
There have been some significant changes in the core side, both for
 ALSA and ASoC, while lots of development have been seen in SOF, as
 well as many small fixes/improvements for ASoC codecs and platforms.
 Below is a highlight in this cycle:
 
 Core:
 - The unification of PCM vmalloc buffer allocation helpers into the
   standard API
 - Clean up of the default PCM mmap handling for vmalloc & SG-buffer
 - Fix potential races at ALSA timer open
 - A few new PCM API extensions; just preliminary core changes, the
   actual changes in drivers will be merged in 5.6
 - Continued ASoC componentization works; now almost everything is a
   common ASoC component object.  A lot of refactoring and
   simplification have been done along with it.
 
 ASoC:
 - Many fixes to the Sound Open Firmware (SOF) code
 - Wake on voice support for Chromebooks
 - SPI support and trigger word detection for RT5677
 - New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
   with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770
 
 HD-audio:
 - Improved Intel DSP configuration / probe code for SOF
 - Plumbing the legacy HD-audio driver with Intel SOF HDMI
 - DP-MST support for Nvidia HDMI codecs
 - Realtek quirks cleanups and new additions as usual
 
 Others:
 - Lots of refactoring and cleanups for FireWire; period-size sharing,
   h/w IRQ interval configuration, clock recovery improvements, etc
 - USB-audio: Scarlett mixer quirks
 - Cleanups of PCM calls in various drivers (including media and USB)
   to adapt the core API changes

Pull power management updates from Rafael Wysocki:
 "These include cpuidle changes to use nanoseconds (instead of
  microseconds) as the unit of time and to simplify checks for disabled
  idle states in the idle loop, some cpuidle fixes and governor updates,
  assorted cpufreq updates (driver updates mostly and a few core fixes
  and cleanups), devfreq updates (dominated by the tegra30 driver
  changes), new CPU IDs for the RAPL power capping driver, relatively
  minor updates of the generic power domains (genpd) and operation
  performance points (OPP) frameworks, and assorted fixes and cleanups.

  There are also two maintainer information updates: Chanwoo Choi will
  be maintaining the devfreq subsystem going forward and Todd Brandt is
  going to maintain the pm-graph utility (created by him).

  Specifics:

   - Use nanoseconds (instead of microseconds) as the unit of time in
     the cpuidle core and simplify checks for disabled idle states in
     the idle loop (Rafael Wysocki)

   - Fix and clean up the teo cpuidle governor (Rafael Wysocki)

   - Fix the cpuidle registration error code path (Zhenzhong Duan)

   - Avoid excessive vmexits in the ACPI cpuidle driver (Yin Fengwei)

   - Extend the idle injection infrastructure to be able to measure the
     requested duration in nanoseconds and to allow an exit latency
     limit for idle states to be specified (Daniel Lezcano)

   - Fix cpufreq driver registration and clarify a comment in the
     cpufreq core (Viresh Kumar)

   - Add NULL checks to the show() and store() methods of sysfs
     attributes exposed by cpufreq (Kai Shen)

   - Update cpufreq drivers:
      * Fix for a plain int as pointer warning from sparse in
        intel_pstate (Jamal Shareef)
      * Fix for a hardcoded number of CPUs and stack bloat in the
        powernv driver (John Hubbard)

      * CPU speed bin detection fix for sun50i (Ondrej Jirman)

   - Appoint Chanwoo Choi as the new devfreq maintainer.

   - Update the devfreq core:
      * Check NULL governor in available_governors_show sysfs to prevent
        showing wrong governor information and fix a race condition
        between devfreq_update_status() and trans_stat_show() (Leonard
        Crestez)
      * Add new 'interrupt-driven' flag for devfreq governors to allow
        interrupt-driven governors to prevent the devfreq core from
        polling devices for status (Dmitry Osipenko)
      * Improve an error message in devfreq_add_device() (Matthias
        Kaehlcke)

   - Update devfreq drivers:

0bcd776272 x86/iopl: Make 'struct tss_struct' constant size again 
After the following commit:

  05b042a194: ("x86/pti/32: Calculate the various PTI cpu_entry_area sizes correctly, make the CPU_ENTRY_AREA_PAGES assert precise")

'struct cpu_entry_area' has to be Kconfig invariant, so that we always
have a matching CPU_ENTRY_AREA_PAGES size.

This commit added a CONFIG_X86_IOPL_IOPERM dependency to tss_struct:

  111e7b15cf: ("x86/ioperm: Extend IOPL config to control ioperm() as well")

Which, if CONFIG_X86_IOPL_IOPERM is turned off, reduces the size of
cpu_entry_area by two pages, triggering the assert:

  ./include/linux/compiler.h:391:38: error: call to ‘__compiletime_assert_202’ declared with attribute error: BUILD_BUG_ON failed: (CPU_ENTRY_AREA_PAGES+1)*PAGE_SIZE != CPU_ENTRY_AREA_MAP_SIZE

Simplify the Kconfig dependencies and make cpu_entry_area constant
size on 32-bit kernels again.

2be7d348fe Revert "vfs: properly and reliably lock f_pos in fdget_pos()" 
This reverts commit 0be0ee7181.

I was hoping it would be benign to switch over entirely to FMODE_STREAM,
and we'd have just a couple of small fixups we'd need, but it looks like
we're not quite there yet.

While it worked fine on both my desktop and laptop, they are fairly
similar in other respects, and run mostly the same loads.  Kenneth
Crudup reports that it seems to break both his vmware installation and
the KDE upower service.  In both cases apparently leading to timeouts
due to waitinmg for the f_pos lock.

There are a number of character devices in particular that definitely
want stream-like behavior, but that currently don't get marked as
streams, and as a result get the exclusion between concurrent
read()/write() on the same file descriptor.  Which doesn't work well for
them.

The most obvious example if this is /dev/console and /dev/tty, which use
console_fops and tty_fops respectively (and ptmx_fops for the pty master
side).  It may be that it's just this that causes problems, but we
clearly weren't ready yet.

Because there's a number of other likely common cases that don't have
llseek implementations and would seem to act as stream devices:

  /dev/fuse		(fuse_dev_operations)
  /dev/mcelog		(mce_chrdev_ops)
  /dev/mei0		(mei_fops)
  /dev/net/tun		(tun_fops)
  /dev/nvme0		(nvme_dev_fops)
  /dev/tpm0		(tpm_fops)
  /proc/self/ns/mnt	(ns_file_operations)
  /dev/snd/pcm*		(snd_pcm_f_ops[])

and while some of these could be trivially automatically detected by the
vfs layer when the character device is opened by just noticing that they
have no read or write operations either, it often isn't that obvious.

Some character devices most definitely do use the file position, even if
they don't allow seeking: the firmware update code, for example, uses
simple_read_from_buffer() that does use f_pos, but doesn't allow seeking
back and forth.

We'll revisit this when there's a better way to detect the problem and
fix it (possibly with a coccinelle script to do more of the FMODE_STREAM
annotations).

Pull x86 iopl updates from Ingo Molnar:
 "This implements a nice simplification of the iopl and ioperm code that

  permissive mode, while trapping CLI/STI/POPF/PUSHF uses in user-space
  if they change the interrupt flag.

  This implements that feature, with testing facilities and related

[ "Simplification" may be an over-statement. The main goal is to avoid
  the cli/sti of iopl by effectively implementing the IO port access
  parts of iopl in terms of ioperm.

  This may end up not workign well in case people actually depend on

     EXCEPTION_TABLE into the RO_DATA area, where they belong on most
     architectures. (Kees Cook)

   - Switch the x86 linker fill byte from x90 (NOP) to 0xcc (INT3), to
     trap jumps into the middle of those padding areas instead of
     sliding execution. (Kees Cook)

   - A thorough cleanup of symbol definitions within x86 assembler code.
     The rather randomly named macros got streamlined around a
     (hopefully) straightforward naming scheme:

        SYM_START(name, linkage, align...)
        SYM_END(name, sym_type)

        SYM_FUNC_START(name)
        SYM_FUNC_END(name)

        SYM_CODE_START(name)
        SYM_CODE_END(name)

        SYM_DATA_START(name)
        SYM_DATA_END(name)

     etc - with about three times of these basic primitives with some
     label, local symbol or attribute variant, expressed via postfixes.

     No change in functionality intended. (Jiri Slaby)

   - Misc other changes, cleanups and smaller fixes"

a86f69d334 spi: Updates for v5.5 
Lots of stuff going on in the core for SPI this time around, the two big
 changes both being around time in different forms:
 
  - A rework of delay times from Alexandru Ardelean which makes the ways
    in which they are specified more consistent between drivers so that
    what's available to clients is less dependent on the hardware
    implementation.
  - Support for PTP timestamping of transfers from Vladimir Oltean,
    useful for use with precision clocks with SPI control interfaces.
  - Big cleanups for the Atmel, PXA2xx and Zynq QSPI drivers.
