[PATCH v2 0/3] KVM: Fix and clean up kvm_vcpu_map[_readonly]() usages

[Peter Fang]

kvm_vcpu_map() and kvm_vcpu_map_readonly() are declared to take a gpa_t
in kvm_host.h when they're supposed to take a gfn_t. First fix the
function prototypes, and then refactor them to correctly take a gpa_t,
reducing boilerplate gpa->gfn conversions at all call sites.

No actual harm has been done yet as all of the call sites are correctly
passing in a gfn.

No functional change intended. All changes are compile-tested on x86 and
ppc, which are the current users of these APIs.

---

v1 -> v2:
  - Rebased on top of latest kvm.git#master
  - As suggested by Yosry, refactor the APIs to reduce boilerplate code
    at call sites
