Subject: [PATCH kvm-unit-tests v2 0/3] svm: INIT test and test_run on selected vcpu

INIT intercept test and the ability to execute test_run
on a selected vcpu

Changes from v1:

1) Incorporated feedback:
	- DR6/DR7/CR2/DEBUGCTL should not be need.
	- HSAVE should be set to a different page for each vCPU
	- The on_cpu to set EFER should be in setup_svm
	- The on_cpu to set cr0/cr3/cr4 should be in setup_vm.

2) Execute tests on selected vcpu using on_cpu_async so the tests
may use the on_cpu functions without causing an ipi_lock deadlock.

3) Added additional test svm_init_startup_test which inits the vcpu and
restarts with sipi.

Cathy Avery (3):
  svm: Add ability to execute test via test_run on a vcpu other than
    vcpu 0
  svm: INIT and STARTUP ipi test
  svm: INIT intercept test
