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.
