Subject: [PATCH v7 27/31] x86/mm: Make INVPCID type macros available to assembly
Date: Fri, 14 Nov 2025 16:14:24 +0100 [thread overview]
Message-ID: <20251114151428.1064524-7-vschneid@redhat.com> (raw)
In-Reply-To: <20251114150133.1056710-1-vschneid@redhat.com>
A later commit will introduce a pure-assembly INVPCID invocation, allow
assembly files to get the type definitions.
