Hi Linus,

Could you please pull the changes below? There are a few arm64 fixes
that turned up during the merging window or just before it opened. They
are based on top of the arm64-upstream tag I sent last week. There is a
near conflict in arch/arm64/Kconfig but it seems that git is smart
enough to figure it out. Thanks.

The following changes since commit d54170812ef1c80e0fa3ed3e554a0bbfc2920d9d:

  arm64: fix .idmap.text assertion for large kernels (2023-02-20 18:23:35 +0000)

  arm64: kaslr: don't pretend KASLR is enabled if offset < MIN_KIMG_ALIGN (2023-02-28 11:21:04 +0000)

----------------------------------------------------------------
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.
