  ACPI: tables: Print MULTIPROC_WAKEUP when MADT is parsed (2024-06-17 17:46:28 +0200)

----------------------------------------------------------------
- Unrelated x86/cc changes queued here to avoid ugly cross-merges and
  conflicts:

   - Carve out CPU hotplug function declarations into a separate header
     with the goal to be able to use the lockdep assertions in a more
     flexible manner

   - As a result, refactor cacheinfo code after carving out a function
     to return the cache ID associated with a given cache level

   -  Cleanups

- Add support to be able to kexec TDX guests. For that

   - Expand ACPI MADT CPU offlining support

   - Add machinery to prepare CoCo guests memory before kexec-ing into a new
     kernel

   - Cleanup, readjust and massage related code

----------------------------------------------------------------
