    Use the accessors rather than frobbing bits directly (the new versions
    are const).

    We're weaning the core code off handing cpumask's around on-stack.
    This introduces arch_send_call_function_ipi_mask(), and by defining
    it, the old arch_send_call_function_ipi is defined by the core code.

    We also take the chance to wean the implementations off the
    obsolescent for_each_cpu_mask(): making send_ipi_mask take the pointer
    seemed the most natural way to ensure all implementations used
    for_each_cpu.

  • 98a79d6a5   cpumask: centralize cpu_online_map and cpu_possible_map ... Browse Code »

    Impact: cleanup

    Each SMP arch defines these themselves. Move them to a central
    location.

    Twists:
    1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a
    CONFIG_INIT_ALL_POSSIBLE for this rather than break them.

    2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'.
    Those archs simply have phys_cpu_present_map replaced everywhere.

    3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky
    so I just manipulate them both in sync.

    4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map'
    declarations.

  • 97dcb82de   [MIPS] Define MIPS_CPU_IRQ_BASE in generic header ... Browse Code »

    The irq_base for {mips,rm7k,rm9k}_cpu_irq_init() are constant on all
    platforms and are same value on most platforms (0 or 16, depends on
    CONFIG_I8259). Define them in asm-mips/mach-generic/irq.h and make
    them customizable. This will save a few cycle on each CPU interrupt.

    A good side effect is removing some dependencies to MALTA in generic
    SMTC code.

    Although MIPS_CPU_IRQ_BASE is customizable, this patch changes irq
    mappings on DDB5477, EMMA2RH and MIPS_SIM, since really customizing
    them might cause some header dependency problem and there seems no
    good reason to customize it. So currently only VR41XX is using custom
    MIPS_CPU_IRQ_BASE value, which is 0 regardless of CONFIG_I8259.

    Testing this patch on those platforms is greatly appreciated. Thank
    you.

    Further incorporation of generic irq framework. Replacing __do_IRQ()
    by proper flow handler would make the irq handling path a bit simpler
    and faster.

    * use generic_handle_irq() instead of __do_IRQ().
    * use handle_level_irq for obvious level-type irq chips.
    * use handle_percpu_irq for irqs marked as IRQ_PER_CPU.
    * setup .eoi routine for irq chips possibly used with handle_percpu_irq.
