[ 02/56] kernel/signal.c: use __ARCH_HAS_SA_RESTORER instead of SA_RESTORER

[Greg Kroah-Hartman]

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>

commit 522cff142d7d2f9230839c9e1f21a4d8bcc22a4a upstream.

__ARCH_HAS_SA_RESTORER is the preferred conditional for use in 3.9 and
later kernels, per Kees.
