ARM: pm: make MULTI_CPU and !MULTI_CPU resume paths the same
Eliminate the differences between MULTI_CPU and non-MULTI_CPU resume paths, making the saved structure identical irrespective of the way the kernel was configured. Acked-by: Frank Hofmann <frank.hofmann@tomtom.com> Tested-by: Kevin Hilman <khilman@ti.com> Acked-by: Jean Pihet <j-pihet@ti.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
