Subject: [patch part-III V2 01/23] x86/traps: Split trap numbers out in a seperate header
Date: Mon, 09 Mar 2020 00:14:11 +0100 [thread overview]
Message-ID: <20200308231718.541278188@linutronix.de> (raw)
In-Reply-To: 20200308231410.905396057@linutronix.de
From: Thomas Gleixner <tglx@linutronix.de>
So they can be used in ASM code. For this it is also necessary to convert
them to defines. Will be used for the rework of the entry code.
