Subject: [PATCH v4 0/2] Two x86 fixes

Hi,

Two fixes for x86 arch.

## Changelog

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.

## Short Summary

Patch 1, fixes the wrong asm constraint in delay_loop function.

Fortunately, the constraint violation that's fixed by patch 1 doesn't
yield any bug due to the nature of System V ABI. Should we backport
this?

Patch 2, fixes memory leak in mce/amd code.
