Pull arm64 fixes from Will Deacon:
 "A mixture of compiler/static checker resolutions and a couple of MTE
  fixes:

   - Avoid erroneously marking untagged pages with PG_mte_tagged

   - Always reset KASAN tags for destination page in copy_page()

   - Mark PMU header functions 'static inline'

   - Fix some sparse warnings due to missing casts"

* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
  arm64: mte: Do not set PG_mte_tagged if tags were not initialized
  arm64: Also reset KASAN tag if page is not PG_mte_tagged
  arm64: perf: Mark all accessor functions inline
  ARM: perf: Mark all accessor functions inline
  arm64: vdso: Pass (void *) to virt_to_page()
  arm64/mm: mark private VM_FAULT_X defines as vm_fault_t
