From d313d4e72df38c1f6f7af9a0c4a101fd94541244 Mon Sep 17 00:00:00 2001 From: Paul Bolle Date: Sat, 9 Jun 2012 23:04:01 +0200 Subject: parisc: remove unused compat_rt_sigframe.h header Nothing uses compat_rt_sigframe.h anymore. Commit f671c45df23005692daa200aba768c642fb14ef2 ("[PARISC] Arch-specific compat signals") removed all includes of that header. It also basically copied that entire header verbatim into signal32.h. It seems it was just forgotten to also remove compat_rt_sigframe.h from the tree. Remove that header now.
