2009-06-10KVM: Fix unneeded instruction skipping during task switching.Gleb Natapov
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.

2009-03-24KVM: SVM: Move EFER and MSR constants to generic x86 codeAlexander Graf
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.

2008-12-31KVM: SVM: move svm.h to include/asmEduardo Habkost
svm.h will be used by core code that is independent of KVM, so I am moving it outside the arch/x86/kvm directory. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
