   stable): reverting the flushing of the SME hardware state along with
   the thread flushing and making sure we have the correct vector length
   before reallocating.

 - An ACPI/IORT fix to avoid skipping ID mappings whose "number of IDs"
   is 0 (the spec reports the number of IDs in the mapping range minus
   1).

      Revert "mm,memblock: reset memblock.reserved to system init state to prevent UAF" · c442a957
      Mike Rapoport (IBM) authored 
      This reverts commit 9e46e4dc

.

kbuild reports a warning in memblock_remove_region() because of a false
positive caused by partial reset of the memblock state.

Doing the full reset will remove the false positives, but will allow
late use of memblock_free() to go unnoticed, so it is better to revert
the offending commit.

      mm/mempolicy: Take VMA lock before replacing policy · 6c21e066
      Jann Horn authored 
      

mbind() calls down into vma_replace_policy() without taking the per-VMA
locks, replaces the VMA's vma->vm_policy pointer, and frees the old
policy.  That's bad; a concurrent page fault might still be using the
old policy (in vma_alloc_folio()), resulting in use-after-free.

Normally this will manifest as a use-after-free read first, but it can
result in memory corruption, including because vma_alloc_folio() can
call mpol_cond_put() on the freed policy, which conditionally changes
the policy's refcount member.

This bug is specific to CONFIG_NUMA, but it does also affect non-NUMA
systems as long as the kernel was built with CONFIG_NUMA.
