2008-08-18x86: fix i486 suspend to disk CR4 oopsDavid Fries
arch/x86/power/cpu_32.c __save_processor_state calls read_cr4() only a i486 CPU doesn't have the CR4 register. Trying to read it produces an invalid opcode oops during suspend to disk. Use the safe rc4 reading op instead. If the value to be written is zero the write is skipped. arch/x86/power/hibernate_asm_32.S done: swapped the use of %eax and %ecx to use jecxz for the zero test and jump over store to %cr4. restore_image: s/%ecx/%eax/ to be consistent with done: In addition to __save_processor_state, acpi_save_state_mem, efi_call_phys_prelog, and efi_call_phys_epilog had checks added (acpi restore was in assembly and already had a check for non-zero). There were other reads and writes of CR4, but MCE and virtualization shouldn't be executed on a i486 anyway. Signed-off-by: David Fries <david@fries.net> Acked-by: H.

2008-02-09x86 PM: rename 32-bit files in arch/x86/powerRafael J. Wysocki
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.
