[PATCH 0/3] KVM: Clean up guest/host cache read/write code

[Sean Christopherson]

Minor cleanup to fix the underlying crustiness that led to an uninitialized
variable warning reported by Barret.

The first two patches are tagged with Fixes:, but I don't know that they're
actually worth backporting to stable.  Functionally, everthing works, it's
just a bit weird and AFAICT not what is intended.  It might be preferable
to take Barret's patch[*] first and only mark that for stable, as it fixes
the immediate issue without revamping __kvm_gfn_to_hva_cache_init().

Sean Christopherson (3):
  KVM: Check for a bad hva before dropping into the ghc slow path
  KVM: Clean up __kvm_gfn_to_hva_cache_init() and its callers
  KVM: Return immediately if __kvm_gfn_to_hva_cache_init() fails
