From aca6ca10974aa78adfb47291722ce851160213e4 Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 15 Jun 2006 20:28:03 +0100 Subject: [PATCH] [ARM] Gather common sigframe saving code into setup_sigframe() Gather the common sigmask savbing code inside setup_sigcontext(), and rename the function setup_sigframe(). Pass it a sigframe structure.
