Hi tglx and all,
Can you please take a look at this patchset (3 patches in total)?

IMO it's better for the 3 patches to go through the tip.git tree, but if you
(the x86 maintainers) have no objection, the patches can also go through
Saha Levin's Hyper-V tree, because the dependent patches have landed
in Linus's tree now.

Thanks,
-- Dexuan
