Subject: [patch 08/10] x86/entry/32: Remove the 0/-1 distinction from exception entries
Date: Tue, 25 Feb 2020 22:36:44 +0100	[thread overview]
Message-ID: <20200225220216.933457250@linutronix.de> (raw)
In-Reply-To: <20200225213636.689276920@linutronix.de>

Nothing cares about the -1 "mark as interrupt" in the errorcode anymore. Just
use 0 for all excpetions which do not have an errorcode consistently.
