[PATCH 0/4] KVM: x86: Collect host state snapshots into a struct

[Sean Christopherson <seanjc@google.com>]

Add a global "kvm_host" structure to hold various host values, e.g. for
EFER, XCR0, raw MAXPHYADDR etc., instead of having a bunch of one-off
variables that inevitably need to be exported, or in the case of
shadow_phys_bits, are buried in a random location and are awkward to use,
leading to duplicate code.

Sean Christopherson (4):
  KVM: x86: Add a struct to consolidate host values, e.g. EFER, XCR0,
    etc...
  KVM: SVM: Use KVM's snapshot of the host's XCR0 for SEV-ES host state
  KVM: x86/mmu: Snapshot shadow_phys_bits when kvm.ko is loaded
  KVM: x86: Move shadow_phys_bits into "kvm_host", as "maxphyaddr"
