9c2e881945 KVM: selftests: hyperv_svm_test: Introduce L2 TLB flush test
Enable Hyper-V L2 TLB flush and check that Hyper-V TLB flush hypercalls
from L2 don't exit to L1 unless 'TlbLockCount' is set in the Partition
assist page.

26b516bb39 x86/hyperv: KVM: Rename "hv_enlightenments" to "hv_vmcb_enlightenments"
Now that KVM isn't littered with "struct hv_enlightenments" casts, rename
the struct to "hv_vmcb_enlightenments" to highlight the fact that the
struct is specifically for SVM's VMCB.

No functional change intended.

68ae7c7bc5 KVM: SVM: Add a proper field for Hyper-V VMCB enlightenments
Add a union to provide hv_enlightenments side-by-side with the sw_reserved
bytes that Hyper-V's enlightenments overlay.  Casting sw_reserved
everywhere is messy, confusing, and unnecessarily unsafe.

No functional change intended.

381fc63ac0 KVM: selftests: Move "struct hv_enlightenments" to x86_64/svm.h
Move Hyper-V's VMCB "struct hv_enlightenments" to the svm.h header so
that the struct can be referenced in "struct vmcb_control_area".
Alternatively, a dedicated header for SVM+Hyper-V could be added, a la
x86_64/evmcs.h, but it doesn't appear that Hyper-V will end up needing
a wholesale replacement for the VMCB.

No functional change intended.

3d5f8d0378 KVM: selftests: Drop unused SVM_CPUID_FUNC macro
Drop SVM_CPUID_FUNC to reduce the probability of tests open coding CPUID
checks instead of using kvm_cpu_has() or this_cpu_has().

29f557d553 KVM: selftests: nSVM: Update 'struct vmcb_control_area' definition
There's a copy of 'struct vmcb_control_area' definition in KVM selftests,
update it to allow testing of the newly introduced features.

Add the basic infrastructure needed to test AMD nested SVM.
This is largely copied from the KVM unit test infrastructure.
