Subject: [REVIEW][PATCH 1/6] signal/sparc: Move EMT_TAGOVF into the generic siginfo.h
Date: Tue, 25 Sep 2018 19:19:01 +0200 [thread overview]
Message-ID: <20180925171906.19683-1-ebiederm@xmission.com> (raw)
In-Reply-To: <87h8idv6nw.fsf@xmission.com>
When moving all of the architectures specific si_codes into
siginfo.h, I apparently overlooked EMT_TAGOVF. Move it now.
Remove the now redundant test in siginfo_layout for SIGEMT
as now NSIGEMT is always defined.
