Sean Christopherson f98c1e7712 KVM: VMX: Add proper cache tracking for CR4 ... Move CR4 caching into the standard register caching mechanism in order to take advantage of the availability checks provided by regs_avail. This avoids multiple VMREADs and retpolines (when configured) during nested VMX transitions as kvm_read_cr4_bits() is invoked multiple times on each transition, e.g. when stuffing CR0 and CR3. As an added bonus, this eliminates a kvm_x86_ops hook, saves a retpoline on SVM when reading CR4, and squashes the confusing naming discrepancy of "cache_reg" vs. "decache_cr4_guest_bits". No functional change intended.
