Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon: "Given that my availability next week is likely to be poor, here are three arm64 fixes to resolve some issues introduced by features merged last week. I was going to wait until -rc1, but it doesn't make much sense to sit on fixes. Fix some fallout introduced during the merge window: - Build failure when PM_SLEEP is disabled but CPU_IDLE is enabled - Compiler warning from page table dumper w/ 48-bit VAs - Erroneous page table truncation in reported dump" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: mm: dump: don't skip final region arm64: mm: dump: fix shift warning arm64: psci: Fix build breakage without PM_SLEEP
