cea15c2 ("KVM: Move KVM context switch into own function") split

problems due to a label). This patch folds them back together again
and adds
the __noclone attribute to prevent the label from being duplicated.
That won't work on gcc versions that didn't have __noclone yet.
Noclone is fairly recent
(4.5 or 4.4)
Are the gcc versions that don't have noclone susceptible to cloning?
I believe the problem can happen due to inlining already
