[kvm-unit-tests,00/16] kvm-unit-tests: set of fixes and new tests

Message

This is set of fixes and new unit tests that I developed for the
KVM unit tests.

I also did some work to separate the SVM code into a minimal
support library so that you could use it from an arbitrary test.

Best regards,

Maxim Levitsky (16):
  x86: make irq_enable avoid the interrupt shadow
  x86: add few helper functions for apic local timer
  svm: use irq_enable instead of sti/nop
  svm: make svm_intr_intercept_mix_if/gif test a bit more robust
  svm: use apic_start_timer/apic_stop_timer instead of open coding it
  x86: Add test for #SMI during interrupt window
  x86: Add a simple test for SYSENTER instruction.
  svm: add nested shutdown test.
  svm: move svm spec definitions to lib/x86/svm.h
  svm: move some svm support functions into lib/x86/svm_lib.h
  svm: add svm_suported
  svm: move setup_svm to svm_lib.c
  svm: move vmcb_ident to svm_lib.c
  svm: rewerite vm entry macros
  svm: introduce svm_vcpu
  add IPI loss stress test
