From 7d4fdc19fc134f69f3711c14e63caef56aee0f2a Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 15 Jun 2006 20:13:25 +0100 Subject: [PATCH] [ARM] Merge sigcontext and sigmask members of sigframe ucontext contains both the sigcontext and sigmask structures, and is also used for rt signal contexts. Re-use this structure for non-rt signals.
