Andrey Konovalov 688abddcfa BACKPORT: FROMGIT: kasan, vmalloc, arm64: mark vmalloc mappings as pgprot_tagged 
(Backport: conflicts due to adjacent lines changed;
 add pgtable.h include to arch/arm64/include/asm/vmalloc.h.)

HW_TAGS KASAN relies on ARM Memory Tagging Extension (MTE).  With MTE, a
memory region must be mapped as MT_NORMAL_TAGGED to allow setting memory
tags via MTE-specific instructions.

Add proper protection bits to vmalloc() allocations.  These allocations
are always backed by page_alloc pages, so the tags will actually be
getting set on the corresponding physical memory.
