[PATCH] swsusp: Change code ordering in disk.c
Change the ordering of code in kernel/power/disk.c so that device_suspend() is
called before disable_nonboot_cpus() and platform_finish() is called after
enable_nonboot_cpus() and before device_resume(), as indicated by the recent
discussion on Linux-PM (cf.
http://lists.osdl.org/pipermail/linux-pm/2006-November/004164.html).
The changes here only affect the built-in swsusp.
