Subject: [PATCH v3 18/19] KVM: selftests: Replace "u64 nested_paddr" with "gpa_t l2_gpa"
Date: Mon, 20 Apr 2026 14:20:03 -0700	[thread overview]
Message-ID: <20260420212004.3938325-19-seanjc@google.com> (raw)
In-Reply-To: <20260420212004.3938325-1-seanjc@google.com>

In x86's nested TDP APIs, use the appropriate gpa_t typedef and rename
variables from nested_paddr to l2_gpa to match KVM x86's nomenclature.

No functional change intended.
