Subject: [ 01/56] signal: Define __ARCH_HAS_SA_RESTORER so we know whether to clear sa_restorer
Date: Tue, 2 Apr 2013 15:49:28 -0700 [thread overview]
Message-ID: <20130402224712.037884059@linuxfoundation.org> (raw)
In-Reply-To: <20130402224711.840825715@linuxfoundation.org>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Hutchings <ben@decadent.org.uk>
Vaguely based on upstream commit 574c4866e33d 'consolidate kernel-side
struct sigaction declarations'.
flush_signal_handlers() needs to know whether sigaction::sa_restorer
is defined, not whether SA_RESTORER is defined. Define the
__ARCH_HAS_SA_RESTORER macro to indicate this.
