      Merge branch 'rwonce/rework' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux · 4152d146
      Linus Torvalds authored 
      Pull READ/WRITE_ONCE rework from Will Deacon:
 "This the READ_ONCE rework I've been working on for a while, which
  bumps the minimum GCC version and improves code-gen on arm64 when
  stack protector is enabled"

[ Side note: I'm _really_ tempted to raise the minimum gcc version to
  4.9, so that we can just say that we require _Generic() support.

  That would allow us to more cleanly handle a lot of the cases where we
  depend on very complex macros with 'sizeof' or __builtin_choose_expr()
  with __builtin_types_compatible_p() etc.

  This branch has a workaround for sparse not handling _Generic(),
  either, but that was already fixed in the sparse development branch,
  so it's really just gcc-4.9 that we'd require.   - Linus ]

      Linus Torvalds authored 
      Pull more power management updates from Rafael Wysocki:
 "These are operating performance points (OPP) framework updates mostly,
  including support for interconnect bandwidth in the OPP core, plus a
  few cpufreq changes, including boost support in the CPPC cpufreq
  driver, an ACPI device power management fix and a hibernation code
  cleanup.

  Specifics:

   - Add support for interconnect bandwidth to the OPP core (Georgi
     Djakov, Saravana Kannan, Sibi Sankar, Viresh Kumar).

   - Add support for regulator enable/disable to the OPP core (Kamil
     Konieczny).

   - Add boost support to the CPPC cpufreq driver (Xiongfeng Wang).

   - Make the tegra186 cpufreq driver set the
     CPUFREQ_NEED_INITIAL_FREQ_CHECK flag (Mian Yousaf Kaukab).

   - Prevent the ACPI power management from using power resources with
     devices where the list of power resources for power state D0 (full
     power) is missing (Rafael Wysocki).

   - Annotate a hibernation-related function with __init (Christophe
     JAILLET)"

  cpufreq: dt: Add support for interconnect bandwidth scaling
  opp: Update the bandwidth on OPP frequency changes
