  • 00024be96   x86: Fix resume from suspend when CONFIG_CC_STACKPROTECTOR ... Browse Code »

    Patch 08687aec71bc9134fe336e561f6did877bacf74fc0a (x86: unify
    power/cpu_(32|64).c) renamed cpu_32.c to cpu.c, but did not update
    the special compilation flags for the file for the new name.

    This patch fixes the compilation flags, and therefore fixes resume
    from suspend on my Acer Aspire One.

    [rjw: The regression from 2.6.30 fixed by this patch is tracked as
    http://bugzilla.kernel.org/show_bug.cgi?id=13661]

    This is the last unification step. Here we do remove one of the files
    and rename the left one as cpu.c, as both are now the same.
    Also update power/Makefile, telling it to build cpu.o, instead of
    cpu_(32|64).o

  • 9b7b89efa   x86: disable stack-protector for __restore_processor_state() ... Browse Code »

    The __restore_processor_state() fn restores %gs on resume from S3. As
    such, it cannot be protected by the stack-protector guard since %gs will
    not be correct on function entry.

    There are only a few other fns in this file and it should not negatively
    impact kernel security that they will also have the stack-protector
    guard removed (and so it's not worth moving them to another file).

    Without this change, S3 resume on a kernel built with
    CONFIG_CC_STACKPROTECTOR_ALL=y will fail.

  • ef8b03fab   x86 PM: consolidate suspend and hibernation code ... Browse Code »

    Move the hibernation-specific code from arch/x86/power/suspend_64.c
    to a separate file (hibernate_64.c) and the CPU-handling code to
    cpu_64.c (in line with the corresponding 32-bit code).

    Simplify arch/x86/power/Makefile .
