Subject: [PATCH v3 03/19] KVM: selftests: Use gpa_t for GPAs in Hyper-V selftests
Date: Mon, 20 Apr 2026 14:19:48 -0700	[thread overview]
Message-ID: <20260420212004.3938325-4-seanjc@google.com> (raw)
In-Reply-To: <20260420212004.3938325-1-seanjc@google.com>

From: David Matlack <dmatlack@google.com>

Fix various Hyper-V selftests to use gpa_t for variables that contain
guest physical addresses, rather than gva_t.  In practice, the bugs are
benign as both gva_t and gpa_t are u64 typedefs, i.e. gpa_t and gva_t are
interchangeable from a functional perspective, the code is just confusing.

No functional change intended.

[sean: call out that both are u64 typedefs]
