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
