[PATCH 0/4] Refactor vcpu creation flow of x86 arch

When reading the vcpu creationg flow of vmx, I find it hard to follow since it
mixes the data structure allocation and initilization together.

This series tries to make the vcpu creation flow more clear that first
allocating data structure and then initializing them. In this way, it helps
move FPU allocation to generic x86 code (Patch 4).

This series intends to do no functional change. I just tested it with
kvm_unit_tests for vmx since I have no AMD machine at hand.

Xiaoyao Li (4):
KVM: VMX: rename {vmx,nested_vmx}_vcpu_setup functions
KVM: VMX: Setup MSR bitmap only when has msr_bitmap capability
KVM: X86: Refactor kvm_arch_vcpu_create
KVM: X86: Make vcpu's FPU allocation a common function
