[GIT PULL] x86/mm for 6.9

[Dave Hansen]

Hi Linus,

Please pull some x86/mm changes for 6.9.  The three changes are quite
diverse.  No real common themes across them.

There is an extra merge in here from Ingo after 6.8-rc1.  I believe
there were some early 6.8 bugs that were complicating testing x86/mm
and the merge made thing easier.

  x86/mm/cpa: Warn for set_memory_XXcrypted() VMM fails (2024-02-22 14:25:41 -0800)

----------------------------------------------------------------
 * Add a warning when memory encryption conversions fail.  These
   operations require VMM cooperation, even in CoCo environments
   where the VMM is untrusted.  While it's _possible_ that memory
   pressure could trigger the new warning, the odds are that a
   guest would only see this from an attacking VMM.
 * Simplify page fault code by re-enabling interrupts unconditionally
 * Avoid truncation issues when pfns are passed in to
   pfn_to_kaddr() with small (<64-bit) types.
