cpumask: Use accessors for cpu_*_mask: mips

2009-09-24T00:04:48+00:00

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

cpumask: arch_send_call_function_ipi_mask: mips

2009-09-24T00:04:45+00:00

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.

MIPS: Add arch generic CPU hotplug

2009-06-24T17:34:40+00:00

Each platform has to add support for CPU hotplugging itself by providing
suitable definitions for the cpu_disable and cpu_die of the smp_ops
methods and setting SYS_SUPPORTS_HOTPLUG_CPU.  A platform should only set
SYS_SUPPORTS_HOTPLUG_CPU once all it's smp_ops definitions have the
necessary changes.  This patch contains the changes to the dummy smp_ops
definition for uni-processor systems.

Parts of the code contributed by Cavium Inc.

MIPS: Build fix - include into all smp_processor_id() users.

2009-06-24T17:34:39+00:00

Some of the were relying into smp.h being dragged in by another header
which of course is fragile.   uses smp_processor_id()
only in macros and including smp.h there leads to an include loop, so
don't change cpu-info.h.

MIPS: Make a needlessly global symbol static in arch/mips/kernel/smp.c

2009-03-30T12:49:45+00:00

The variable cpu_callin_map is needlessly defined global, so let's
make it static now.

Build-tested using malta_defconfig.

cpumask: centralize cpu_online_map and cpu_possible_map

2008-12-13T10:49:41+00:00

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.
