Subject: [PATCH v2 0/3] KVM: Fix and clean up kvm_vcpu_map[_readonly]() usages
Date: Tue, 7 Apr 2026 17:11:27 -0700 [thread overview]
Message-ID: <20260408001137.3290444-1-peter.fang@intel.com> (raw)
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
