Hi Don,

Thanks for following up. All the patches are now in.

I am working on a few new NMI issues so I'll be sending out a few patches
in a day or so. I've committed one critical fix to our 2.6.32 tree and am now
working on forward-porting it to tip/master:

http://git.chromium.org/gitweb/?p=chromiumos/third_party/kernel.git;a=commitdiff;h=2a825f5f38f24e655dd655253eaaa5a82460a43e;hp=09ecdd5b43b9df930efd51a3fe317c18907a6c2d

Regards,
Mandeep
