x86 PM: rename 32-bit files in arch/x86/power
Rename cpu.c, suspend.c and swsusp.S in arch/x86/power to cpu_32.c, hibernate_32.c and hibernate_asm_32.S, respectively, and update the purpose and copyright information in these files. Update the Makefile in arch/x86/power to reflect the above changes. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Pavel Machek <pavel@ucw.cz> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

8 * image could very well be data page in "new" image, and overwriting
9 * your own stack under you is bad idea.
