Subject: [PATCH v6 0/2] Two x86 fixes

Hi,

This is the v6 of two x86 fixes.

1) x86/delay: Fix the wrong Assembly constraint in delay_loop() function.
2) x86/MCE/AMD: Fix memory leak when `threshold_create_bank()` fails.

## Changelog

v6:
  - Remove unnecessary Cc tags.
  - Undo the stable mark for patch 1.
  - Update commit message, emphasize the danger when the compiler
    decides to inline the function.
  - Fix the Fixes tag sha1 in patch 1.
  - Change the helper function name to __threshold_remove_device().

v5:
  - Mark patch #1 for stable.
  - Commit message improvement for patch #1 and #2.
  - Fold in changes from Yazen and Alviro (for patch #2).

v4:
  - Address comment from Greg, sha1 commit Fixes only needs
    to be 12 chars.
  - Add the author of the fixed commit to the CC list.

v3:
  - Fold in changes from Alviro, the previous version is still
    leaking @bank[n].

v2:
  - Fix wrong copy/paste.
