Here is the context:

https://bugzilla.redhat.com/show_bug.cgi?id=494469

The kvm patch is from May 12 2009 and was merged into mainline Linux.

Merging this gPXE patch would require checking that other instances of
sti in gPXE are unaffected, or adding the workaround there too.  Right
now I'm not sure that all codepaths in gPXE are unaffected and this
patch only fixes romprefix.S.
