      The previous two suspend related fixes both fix the same issue
      so only one of them (the newer one) is actually needed.

      As reported by Chris, both commits
              b403125d "ARM: rockchip: fix undefined instruction of reset_ctrl_regs"
              0ea001d3 "ARM: rockchip: disable dapswjdp during suspend"
      actually fix the same issue and b403125d is the older one, which got
      superseded by 0ea001d3
      
      . Therefore revert the obsolete one again.

      ARM: EXYNOS: Fix dereference of ERR_PTR returned by of_genpd_get_from_provider · 0b7dc0ff
      Krzysztof Kozlowski authored
      ERR_PTR was dereferenced during sub domain parsing, if parent domain
      could not be obtained (because of invalid phandle or deferred
      registration of parent domain).
      
      The Exynos power domain code checked whether
      of_genpd_get_from_provider() returned NULL and in that case it skipped
      that power domain node. However this function returns ERR_PTR or valid
      pointer, not NULL.

      ARM: EXYNOS: Don't try to initialize suspend on old DT · e5cbec61
      Julien Grall authored
      Since commit 8b283c02
      
       ("ARM: exynos4/5: convert pmu wakeup to
      stacked domains"), a suspend/resume is not supported on old DT.
      
      Although, rather than printing a warning and continue to boot, the
      kernel will segfault just after:

      This is happening because pmu_base_addr is only initialized when the
      PMU is an interrupt controller. It's not the case on old DT.

      ARM: dts: Add keep-power-in-suspend to WiFi SDIO node for Peach Boards · b2706879
      Javier Martinez Canillas authored
      
      
      The Marvell mwifiex driver prevents the system to enter into a suspend
      state if the card power is not preserved during a suspend/resume cycle.
      
      So Suspend-to-RAM and Suspend-to-idle is failing on Exynos5800 Peach Pi
      and Exynos5420 Peach Pit Chromebooks.
      
      Add the keep-power-in-suspend Power Management property to the SDIO/MMC
      node so the mwifiex suspend handler doesn't fail and the system is able
      to enter into a suspend state.

      drm: Zero out invalid vblank timestamp in drm_update_vblank_count. · fdb68e09
      Mario Kleiner authored
      Since commit 844b03f2
      
       we make
      sure that after vblank irq off, we return the last valid
      (vblank count, vblank timestamp) pair to clients, e.g., during
      modesets, which is good.
      
      An overlooked side effect of that commit for kms drivers without
      support for precise vblank timestamping is that at vblank irq
      enable, when we update the vblank counter from the hw counter, we
      can't update the corresponding vblank timestamp, so now we have a
      totally mismatched timestamp for the new count to confuse clients.
      
      Restore old client visible behaviour from before Linux 3.17, but
      zero out the timestamp at vblank counter update (instead of disable
      as in original implementation) if we can't generate a meaningful
      timestamp immediately for the new vblank counter. This will fix
      this regression, so callers know they need to retry again later
      if they need a valid timestamp, but at the same time preserves
      the improvements made in the commit mentioned above.

      Pull user-namespace fix from Eric Biederman:
       "Eric Windish recently reported a really bug that allows mounting fresh
        copies of proc and sysfs when it really should not be allowed.  The
        code attempted to verify that proc and sysfs were fully visible but
        there is a test missing to ensure that the root of the filesystem is
        visible.  Doh!
      
        The following patch fixes that.
      
        This fixes a containment issue that the docker folks are seeing"

       "Two patches from the irq departement:
      
         - a simple fix to make dummy_irq_chip usable for wakeup scenarios
      
         - removal of the gic arch_extn hackery.  Now that all users are
           converted we really want to get rid of the interface so people wont

      m32r: make flush_cpumask non-volatile. · 1a9f064f
      Rusty Russell authored
      
      
      We cast away the volatile, but really, why make it volatile at all?
      We already do a mb() inside the cpumask_empty() loop.

      Eric W. Biederman authored
      
      
      This fixes a dumb bug in fs_fully_visible that allows proc or sys to
      be mounted if there is a bind mount of part of /proc/ or /sys/ visible.
