    Pull percpu consistent-ops changes from Tejun Heo:
    "Way back, before the current percpu allocator was implemented, static
    and dynamic percpu memory areas were allocated and handled separately
    and had their own accessors. The distinction has been gone for many
    years now; however, the now duplicate two sets of accessors remained
    with the pointer based ones - this_cpu_*() - evolving various other
    operations over time. During the process, we also accumulated other
    inconsistent operations.

    This pull request contains Christoph's patches to clean up the
    duplicate accessor situation. __get_cpu_var() uses are replaced with
    with this_cpu_ptr() and __this_cpu_ptr() with raw_cpu_ptr().

    Unfortunately, the former sometimes is tricky thanks to C being a bit
    messy with the distinction between lvalues and pointers, which led to
    a rather ugly solution for cpumask_var_t involving the introduction of
    this_cpu_cpumask_var_ptr().

    This converts most of the uses but not all. Christoph will follow up
    with the remaining conversions in this merge window and hopefully
    remove the obsolete accessors"

    2

    When a CPU enters a low power state, the contents of the GICv3/4 system
    registers are lost. They need to be saved and restored if required.

    For now, since most of the GICv3 register are set some initial values and
    not modified at runtime, it is better to re-initialise rather than saving
    and restoring them. It may need to be saved and restored in future if
    required.

    This patch adds a notifier to disable the redistributor(if allowed) and
    Group1 interrupts when powering down the processor and to re-initialise
    the system registers on wakeup.

    2

    Currently gic_enable_redist configures the redistributors to never
    assert WakeRequest signal. However when powering down the processors
    with wake-up enabled(i.e suspend), we need to configure it to assert
    that signal.

    This patch extends gic_enable_redist so that the redistributor can be
    configure to assert WakeRequest and hold interrupts as pending. This is
    useful in suspending the processors.

    This patch also adds check to make sure GICR_WAKER is accessible when
    configuring it.

    This is just enough to let pm_clk_*() enable the functional clock, and
    manage it for suspend/resume, if present.
    Before, it was assumed enabled by the bootloader or reset state.

    To prevent the clock from being disabled while the module is needed for
    wake-up, implement irq_chip.irq_set_wake(), which increments/decrements
    the clock's enable_count when needed.

    This patch adds support for the Level-2 interrupt controller
    hardware found in Broadcom Set Top Box System-on-a-Chip devices. This
    interrupt controller is implemented using a single enable register.

    This interrupt controller is always present on the platforms supported
    by the irq-brcmstb-l2 driver, hence the reason why both are compiled
    using the same Kconfig symbol.

    [jac] removed the following warning:
    drivers/irqchip/irq-bcm7120-l2.c: In function 'bcm7120_l2_intc_irq_handle':
