Subject: [PATCH v2 0/2] Remove unneeded MKTME detection

Changes in v2:
- Print the phys_addr bits reduction when BIOS enables MKTME (Kai)
- Remove init of keyid_bits (Kirill)
- Pick up Acked-by tags (Kirill, Kai)
- Update Patch 1 commit message phys addr bits note
- Rebase to latest tiptree
- Add note in this cover letter saying patches are independent

Link to v1: 
https://lore.kernel.org/all/cover.1713929290.git.alison.schofield@intel.com/


Begin original cover letter:
 
MKTME detection was added in anticipation of full kernel support
that never followed. Aside from just good housekeeping, this
cleanup is inspired by users who are confused by the TME/MKTME
messaging during boot.

The first patch cleans up the TME & MKTME detection code and the
second patch removes the unused pconfig code. There are no
dependencies between the 2 patches. The code that Patch 2 removes
is not used anywhere, not even pre-Patch 1.

Testing was done on a platform supporting MKTME using the BIOS
option to enable/disable MKTME prior to boot.

Alison Schofield (2):
  x86/cpu: Remove useless work in detect_tme_early()
  x86/pconfig: Remove unused MKTME pconfig code
