[REVIEW][PATCH 1/6] signal/sparc: Move EMT_TAGOVF into the generic siginfo.h

From: Eric W. Biederman
Date: Tue Sep 25 2018 - 13:19:53 EST


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.
