[PATCH 01/24] KVM: nSVM: fix condition for filtering async PF

[PATCH 01/24] KVM: nSVM: fix condition for filtering async PF

[Paolo Bonzini]

Async page faults have to be trapped in the host (L1 in this case),
since the APF reason was passed from L0 to L1 and stored in the L1 APF
data page.  This was completely reversed: the page faults were passed
to the guest, a L2 hypervisor.

[PATCH 02/24] KVM: nSVM: leave ASID aside in copy_vmcb_control_area

[Paolo Bonzini]

Restoring the ASID from the hsave area on VMEXIT is wrong, because its
value depends on the handling of TLB flushes.  Just skipping the field in
copy_vmcb_control_area will do.
