   - Fix possible NULL pointer dereference in the ACPI processor scaling
     initialization code introduced by a recent cpufreq update (Rafael
     Wysocki).

   - Fix possible deadlock due to suspending cpufreq too late during
     system shutdown (Rafael Wysocki).

     its PM-runtime counterpart to fix an issue with missing delay on
     transitions from D3cold to D0 during system resume from
     suspend-to-idle on some systems (Rafael Wysocki).

   - Drop Dell XPS13 9360 from the LPS0 Idle _DSM blacklist to make it
     use suspend-to-idle by default (Mario Limonciello).

It seems that global pcc_data[pcc_ss_id] can be freed in
acpi_cppc_processor_exit(), but we may later reference this value, so
NULLify it when freed.

Also remove the useless setting of data "pcc_channel_acquired", which
we're about to free.

 "The main thing here is a long-awaited workaround for a CPU erratum on

  Cavium/Marvell.

  At the moment, the workaround is unconditionally enabled for affected
  CPUs at runtime but we may add a command-line option to disable it in
  future if performance numbers show up indicating a significant cost
  for real workloads.

  Summary:

   - Work around Cavium/Marvell ThunderX2 erratum #219

   - Fix regression in mlock() ABI caused by sign-extension of TTBR1 addresses

      由 Linus Torvalds 提交于 
      Pull input fixes from Dmitry Torokhov:
 "The main change is that we are reverting blanket enablement of SMBus
  mode for devices with Elan touchpads that report BIOS release date as
  2018+ because there are older boxes with updated BIOSes that still do
  not work well in SMbus mode.

  We will have to establish whitelist for SMBus mode it looks like"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Revert "Input: elantech - enable SMBus on new (2018+) systems"
  Input: synaptics-rmi4 - avoid processing unknown IRQs
  Input: soc_button_array - partial revert of support for newer surface devices
  Input: goodix - add support for 9-bytes reports
  Input: da9063 - fix capability and drop KEY_SLEEP

      coccinelle: api/devm_platform_ioremap_resource: remove useless script · 283ea345
      由 Alexandre Belloni 提交于 
      While it is useful for new drivers to use devm_platform_ioremap_resource,
this script is currently used to spam maintainers, often updating very
old drivers.  The net benefit is the removal of 2 lines of code in the
driver but the review load for the maintainers is huge.  As of now, more
that 560 patches have been sent, some of them obviously broken, as in:

 https://lore.kernel.org/lkml/9bbcce19c777583815c92ce3c2ff2586@www.loen.fr/

Remove the script to reduce the spam.
