The patch titled
i386 mce: check capability
has been removed from the -mm tree. Its filename was
i386-mce-check-capability.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: i386 mce: check capability
From: "Joachim Deguara" <joachim.deguara@xxxxxxx>
Currently the i386 architecture checks the family for mce capability and this
removes that and uses the CPUID information. Tested on a K8 revE and a
family10h processor.
This eliminates checking of a set AMD procesor family if mce is
allowed and relies on the information being in CPUID.
