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

2009-03-24T09:02:46+00:00

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)

x86: cpu_emergency_svm_disable() function

2008-12-31T14:52:30+00:00

This function can be used by the reboot or kdump code to forcibly
disable SVM on the CPU.

KVM: SVM: move has_svm() code to asm/virtext.h

2008-12-31T14:52:29+00:00

Use a trick to keep the printk()s on has_svm() working as before. gcc
will take care of not generating code for the 'msg' stuff when the
function is called with a NULL msg argument.

x86: cpu_emergency_vmxoff() function

2008-12-31T14:52:29+00:00

Add cpu_emergency_vmxoff() and its friends: cpu_vmx_enabled() and
__cpu_emergency_vmxoff().

x86: asm/virtext.h: add cpu_vmxoff() inline function

2008-12-31T14:52:29+00:00

Unfortunately we can't use exactly the same code from vmx
hardware_disable(), because the KVM function uses the
__kvm_handle_fault_on_reboot() tricks.

KVM: VMX: move cpu_has_kvm_support() to an inline on asm/virtext.h

2008-12-31T14:52:28+00:00

It will be used by core code on kdump and reboot, to disable
vmx if needed.
