Subject: [patch 03/24] x86/entry/64: Reorder idtentries
Date: Tue, 25 Feb 2020 23:16:09 +0100 [thread overview]
Message-ID: <20200225222648.485203436@linutronix.de> (raw)
In-Reply-To: 20200225221606.511535280@linutronix.de
Move them all together so verifying the cleanup patches for binary
equivalence will be easier.
