  • Rather than #define the options manually in the architecture code, add
    Kconfig options for them and select them there instead. This also allows
    us to select the compat IPC version parsing automatically for platforms
    using the old compat IPC interface.

  • There's a small group of odd looking includes in smc37c669.c. These
    includes appear to be if zero-ed out ever since they were added to the
    tree (in v2.1.89). Their purpose is unclear to me. Perhaps they were
    used in someones build system. Whatever their purpose was, nothing else
    uses something comparable. This entire if zero-ed out block might as well
    be removed.

  • The fixups are executed once the pci-device is found which is during
    boot process so __init seems fine as long as the platform does not
    support hotplug.

    However it is possible to remove the PCI bus at run time and have it
    rediscovered again via "echo 1 > /sys/bus/pci/rescan" and this will call
    the fixups again.

  • Does block_sigmask() + tracehook_signal_handler(); called when
    sigframe has been successfully built. All architectures converted
    to it; block_sigmask() itself is gone now (merged into this one).

    I'm still not too happy with the signature, but that's a separate
    story (IMO we need a structure that would contain signal number +
    siginfo + k_sigaction, so that get_signal_to_deliver() would fill one,
    signal_delivered(), handle_signal() and probably setup...frame() -
    take one).

  • Pull smp hotplug cleanups from Thomas Gleixner:
    "This series is merily a cleanup of code copied around in arch/* and
    not changing any of the real cpu hotplug horrors yet. I wish I'd had
    something more substantial for 3.5, but I underestimated the lurking
    horror..."

    Fix up trivial conflicts in arch/{arm,sparc,x86}/Kconfig and
    arch/sparc/include/asm/thread_info_32.h

  • Historical prepare_to_copy() is mostly a no-op, duplicated for majority of
    the architectures and the rest following the x86 model of flushing the extended
    register state like fpu there.

    Remove it and use the arch_dup_task_struct() instead.

  • Rather than requiring architectures that use gpiolib but don't have any
    need to define anything custom to copy an asm/gpio.h provide a Kconfig
    symbol which architectures must select in order to include gpio.h and
    for other architectures just provide the trivial implementation directly.

    This makes it much easier to do gpiolib updates and is also a step towards
    making gpiolib APIs available on every architecture.

    For architectures with existing boilerplate code leave a stub header in
    place which warns on direct inclusion of asm/gpio.h and includes
    linux/gpio.h to catch code that's doing this. Direct inclusion of
    asm/gpio.h has long been deprecated.

  • We always need to pass the last sample period to
    perf_sample_data_init(), otherwise the event distribution will be
    wrong. Thus, modifiyng the function interface with the required period
    as argument. So basically a pattern like this:

    perf_sample_data_init(&data, ~0ULL);
    data.period = event->hw.last_period;

    will now be like that:

    perf_sample_data_init(&data, ~0ULL, event->hw.last_period);

    Avoids unininitialized data.period and simplifies code.
