[GIT PULL] KVM/ARM fixes for 4.4-rc4

[Marc Zyngier]

Hi Paolo,

This pull request contains a number of fixes for 4.4-rc4 (or -rc5 if
we already missed the boat).

The first part is a very nice catch from Pavel, who noticed that we
were not dealing very well (if at all) with the aliasing between two
registers.

The last patch from Ard is a fix for a fix that was merged in
-rc3. Hopefully we got it right this time.

Please pull!
