This patch-set fixes various KVM bugs, mainly in the emulator. Each patch is
independent, except for patches 15-16 (which are intended to fix a single bug).
Patch 19 ist not a real fix for bug but improves the behavior of KVM when it
cannot handle a certain guest behavior.
Some previous fixes were found to be incomplete or faulty. Patches 18,20
handle these cases.
Thanks for reviewing the patches. A separate patch-set which deals with
__lienarize (emulator) related bugs would follow.
