Subject: [PATCH 0/5] KVM: x86: Fix exit handler and emulation bugs

This series of patches fixes various scenarios in which KVM does not follow x86
specifications.  Patches #4 and #5 are related; they reflect a new revision of
the previously submitted patch that dealt with the wrong masking of registers
in long-mode. Patch #3 is a follow-up to the previously sumbitted patch that
fixed the wrong reserved page table masks. Patches #3 and #5 were not tested in
a manner that actually checks the modified behavior. Not all the pathes in
patch #4 were tested.

Thanks for reviewing the patches.

  KVM: x86: Mark bit 7 in long-mode PDPTE according to 1GB pages support
