Merge tag 'arm64-fixes' of git://git./linux/kernel/git/arm64/linux

Pull arm64 fixes from Will Deacon:
 "Summary below, but it's all reasonably straightforward. There are some
  more fixes on the horizon, but nothing disastrous yet.

  Summary:

   - Fix build when KASLR is enabled but CONFIG_ARCH_RANDOM is not set

   - Fix context-switching of SSBS state on systems that implement it

   - Fix spinlock compiler warning introduced during the merge window

   - Fix incorrect header inclusion (linux/clk-provider.h)

   - Use SYSCTL_{ZERO,ONE} instead of rolling our own static variables

   - Don't scream if optional SMMUv3 PMU irq is missing

   - Remove some unused function prototypes"
