c288ea6798 gpio updates for v5.17 
- new testing module: gpio-sim that is scheduled to replace gpio-mockup
 - initial changes aiming at converting all GPIO drivers to using the fwnode
   interface and limiting any references to OF symbols to gpiolib-of.c
 - add support for Tegra234 and Tegra241 to gpio-tegra186
 - add support for new models (SSD201 and SSD202D) to gpio-msc313
 - add basic support for interrupts to gpio-aggregator
 - add support for AMDIF031 HID device to gpio-amdpt
 - drop support for unused platforms in gpio-xlp
 - cleanup leftovers from the removal of the legacy Samsung Exynos GPIO driver
 - use raw spinlocks in gpio-aspeed and gpio-aspeed-sgpio to make PREEMPT_RT
   happy
 - generalize the common 'ngpios' device property by reading it in the core
   gpiolib code so that we can remove duplicate reads from drivers
 - allow line names from device properties to override names set by drivers
 - code shrink in gpiod_add_lookup_table()
 - add new model to the DT bindings for gpio-vf610
 - convert DT bindings for tegra devices to YAML
 - improvements to interrupt handling in gpio-rcar and gpio-rockchip
 - updates to intel drivers from Andy (details in the merge commit)
 - some minor tweaks, improvements and coding-style fixes all around the
   subsystem

Pull gpio updates from Bartosz Golaszewski:
 "The gpio-sim module is back, this time without any changes to
  configfs. This results in a less elegant user-space interface but I
  never got any follow-up on the committable items and didn't want to
  delay this module for several more months.

  Other than that we have support for several new models and some
  support going away. We started working on converting GPIO drivers to
  using fwnode exclusively in order to limit references to OF symbols to
  gpiolib-of.c exclusively. We also have regular tweaks and improvements
  all over the place.

  Summary:

   - new testing module: gpio-sim that is scheduled to replace
     gpio-mockup

   - initial changes aiming at converting all GPIO drivers to using the
     fwnode interface and limiting any references to OF symbols to
     gpiolib-of.c

   - add support for Tegra234 and Tegra241 to gpio-tegra186

   - add support for new models (SSD201 and SSD202D) to gpio-msc313

   - add basic support for interrupts to gpio-aggregator

   - add support for AMDIF031 HID device to gpio-amdpt

   - drop support for unused platforms in gpio-xlp

   - cleanup leftovers from the removal of the legacy Samsung Exynos
     GPIO driver

   - use raw spinlocks in gpio-aspeed and gpio-aspeed-sgpio to make
     PREEMPT_RT happy

   - generalize the common 'ngpios' device property by reading it in the
     core gpiolib code so that we can remove duplicate reads from
     drivers

   - allow line names from device properties to override names set by
     drivers

   - code shrink in gpiod_add_lookup_table()

   - add new model to the DT bindings for gpio-vf610

   - convert DT bindings for tegra devices to YAML

282aa44c21 spi: Updates for v5.17 
This has mostly been a quiet release for the SPI subsystem, almost all
 cleanups and fixes to existing drivers.  A couple of changes that stand
 out:
 
  - Cleanups and support for version specific features in the DesignWare
    controller.
  - Removal of support for Netlogic devices from the XLP driver, the
    platform had previously been removed by MIPS so the support couldn't
    be used.
  - Conversion of several DT bindings to YAML format.

fef8dfaea9 regulator: Updates for v5.17 
This has been a fairly quiet release for the regulator API, the main
 thing has been the addition of helpers for interrupt handling from Matti
 Vaittinen. We do also have support for quite a few new devices and
 included in here is a platform/x86 patch series for Intel INT3472 ACPI
 devices which this is a dependency for the TPS68470 driver.
 
  - Helpers for trivial interrupt notifications, making it easier for
    drivers to handle error interrupts.
  - Support for Dialog DA914x, Maxim MAX2008x, Qualcomm PM8826, PMG1100,
    and PM8450 and TI TPS68470

RISC-V: Use SBI SRST extension when available 
The SBI SRST extension provides a standard way to poweroff and
reboot the system irrespective to whether Linux RISC-V S-mode
is running natively (HS-mode) or inside Guest/VM (VS-mode).

The SBI SRST extension is available in the SBI v0.3 specification.
(Refer, https://github.com/riscv/riscv-sbi-doc/releases/tag/v0.3.0-rc1)

This patch extends Linux RISC-V SBI implementation to detect
and use SBI SRST extension.

c47db13bdf dt-bindings: clock: samsung: extend Exynos7 bindings with UFS 
The UFS for Exynos7 SoC clock controller requires additional input
clocks for the FSYS1 clock controller.  Update the bindings to reflect
this, at least in theory.  In practice, these input clocks are ignored,
so it is rather adjusting of bindings to existing DTS, without affecting
any real users.  I understand that is not how it should be done,
though...

382778edc8 xdp: check prog type before updating BPF link 
The bpf_xdp_link_update() function didn't check the program type before
updating the program, which made it possible to install any program type as
an XDP program, which is obviously not good. Syzbot managed to trigger this
by swapping in an LWT program on the XDP hook which would crash in a helper
call.

Fix this by adding a check and bailing out if the types don't match.

Merge tag 'printk-for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux

Pull printk updates from Petr Mladek:

 - Remove some twists in the console registration code. It does not
   change the existing behavior except for one corner case. The proper
   default console (with tty binding) will be registered again even when
   it has been removed in the meantime. It is actually a bug fix.
   Anyway, this modified behavior requires some manual interaction.

 - Optimize gdb extension for huge ring buffers.

 - Do not use atomic operations for a local bitmap variable.

 - Update git links in MAINTAINERS.

Pull workqueue updates from Tejun Heo:

 - The code around workqueue scheduler hooks got reorganized early 2019
   which unfortuately introdued a couple subtle and rare race conditions
   where preemption can mangle internal workqueue state triggering a
   WARN and possibly causing a stall or at least delay in execution.

   Frederic fixed both early December and the fixes were sitting in
   for-5.16-fixes which I forgot to push. They are here now. I'll
   forward them to stable after they land.

 - The scheduler hook reorganization has more implicatoins for workqueue
   code in that the hooks are now more strictly synchronized and thus
   the interacting operations can become more straight-forward.

   Lai is in the process of simplifying workqueue code and this pull
   request contains some of the patches.

68514dacf2 select: Fix indefinitely sleeping task in poll_schedule_timeout() 
A task can end up indefinitely sleeping in do_select() ->
poll_schedule_timeout() when the following race happens:

  TASK1 (thread1)             TASK2                   TASK1 (thread2)
  do_select()
    setup poll_wqueues table
    with 'fd'
                              write data to 'fd'
                                pollwake()
                                  table->triggered = 1
                                                      closes 'fd' thread1 is
                                                        waiting for
    poll_schedule_timeout()
      - sees table->triggered
      table->triggered = 0
      return -EINTR
    loop back in do_select()

But at this point when TASK1 loops back, the fdget() in the setup of
poll_wqueues fails.  So now so we never find 'fd' is ready for reading
and sleep in poll_schedule_timeout() indefinitely.

Treat an fd that got closed as a fd on which some event happened.  This
makes sure cannot block indefinitely in do_select().

Another option would be to return -EBADF in this case but that has a
potential of subtly breaking applications that excercise this behavior
and it happens to work for them.  So returning fd as active seems like a
safer choice.

4353594eb0 PCI: Use DWORD accesses for LTR, L1 SS to avoid erratum 
Some devices have an erratum such that they only support DWORD accesses to
some registers.  E.g., this Bayhub O2 device ([VID:DID] = [0x1217:0x8621])
only supports DWORD accesses to LTR latency registers and L1 PM substates
control registers:

  https://github.com/rajatxjain/public_shared/blob/main/OZ711LV2_appnote.pdf

The L1 PM substate control registers are DWORD sized, and hence their
access in the kernel is already DWORD sized, so we don't need to do
anything for them.

However, the LTR registers being WORD sized, are in need of a solution.
Convert the WORD sized accesses to these registers into DWORD sized
accesses while saving and restoring them.
