Gleb Natapov	64a7ec0668	KVM: Fix unneeded instruction skipping during task switching. There is no need to skip instruction if the reason for a task switch is a task gate in IDT and access to it is caused by an external even. The problem is currently solved only for VMX since there is no reliable way to skip an instruction in SVM. We should emulate it instead.

KVM: Fix unneeded instruction skipping during task switching.

There is no need to skip instruction if the reason for a task switch
is a task gate in IDT and access to it is caused by an external even.
The problem  is currently solved only for VMX since there is no reliable
way to skip an instruction in SVM. We should emulate it instead.

KVM: SVM: Move EFER and MSR constants to generic x86 code

MSR_EFER_SVME_MASK, MSR_VM_CR and MSR_VM_HSAVE_PA are set in KVM
specific headers. Linux does have nice header files to collect
EFER bits and MSR IDs, so IMHO we should put them there.

While at it, I also changed the naming scheme to match that
of the other defines.

(introduced in v6)

KVM: SVM: move svm.h to include/asm

svm.h will be used by core code that is independent of KVM, so I am
moving it outside the arch/x86/kvm directory.
