Subject: [patch 01/24] x86/traps: Split trap numbers out in a seperate header
Date: Tue, 25 Feb 2020 23:16:07 +0100	[thread overview]
Message-ID: <20200225222648.285655538@linutronix.de> (raw)
In-Reply-To: 20200225221606.511535280@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.
