Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
- In copy_highpage(), only reset the tag of the destination pointer if
KASAN_HW_TAGS is enabled so that user-space MTE does not interfere
with KASAN_SW_TAGS (which relies on top-byte-ignore).
- Remove warning if SME is detected without SVE, the kernel can cope
with such configuration (though none in the field currently).
- In cfi_handler(), pass the ESR_EL1 value to die() for consistency
with other die() callers.
- Disable HUGETLB_PAGE_OPTIMIZE_VMEMMAP on arm64 since the pte
manipulation from the generic vmemmap_remap_pte() does not follow the
required ARM break-before-make sequence (clear the pte, flush the
TLBs, set the new pte). It may be re-enabled once this sequence is
sorted.
- Fix possible memory leak in the arm64 ACPI code if the SMCCC version
and conduit checks fail.
- Forbid CALL_OPS with CC_OPTIMIZE_FOR_SIZE since gcc ignores
-falign-functions=N with -Os.
- Don't pretend KASLR is enabled if offset < MIN_KIMG_ALIGN as no
randomisation would actually take place.
