Linus Torvalds 39ce4395c3 arm64 fixes:
- 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.
