Rafael J. Wysocki 2b5b09b3b5 [PATCH] swsusp: Change pm_ops handling by userland interface
Make the userland interface of swsusp call pm_ops->finish() after
enable_nonboot_cpus() and before resume_device(), as indicated by the recent
discussion on Linux-PM (cf.
http://lists.osdl.org/pipermail/linux-pm/2006-November/004164.html).

This patch changes the SNAPSHOT_PMOPS ioctl so that its first function,
PMOPS_PREPARE, only sets a switch turning the platform suspend mode on, and
its last function, PMOPS_FINISH, only checks if the platform mode is enabled.
This should allow the older userland tools to work with new kernels without
any modifications.

The changes here only affect the userland interface of swsusp.
