Subject: Merge the edge and level gpe handlers into one (now possible since the
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=7fb99a85d17e8a0581a9c7752a1a345a772e02d1;p=openbsd

Merge the edge and level gpe handlers into one (now possible since the
gpe structure tells us whether the gpe is edge or level)
