Subject: [PATCH v4 02/18] coco/tdx: Rename MSR access helpers
Date: Mon, 29 Jun 2026 08:55:28 +0200	[thread overview]
Message-ID: <20260629065544.3643253-3-jgross@suse.com> (raw)
In-Reply-To: <20260629065544.3643253-1-jgross@suse.com>

In order to avoid a name clash with some general MSR access helpers
after a future MSR infrastructure rework, rename the TDX specific
helpers.
