The patch titled
x86: add MCE resume
has been added to the -mm tree. Its filename is
x86-add-mce-resume.patch
Patches currently in -mm which might be from [EMAIL PROTECTED] are

From: Shaohua Li <[EMAIL PROTECTED]>
It's widely seen a MCE non-fatal error reported after resume. It seems MCE
resume is lacked under ia32. This patch tries to fix the gap.
