Subject: [patch V3 02/20] x86/extable: Get rid of redundant macros
Date: Wed, 8 Sep 2021 15:29:13 +0200 (CEST) [thread overview]
Message-ID: <20210908132525.023659534@linutronix.de> (raw)
In-Reply-To: 20210908130922.118265849@linutronix.de
No point in defining the identical macros twice depending on C or assembly
mode. They are still identical.
