2009-09-24cpumask: Use accessors for cpu_*_mask: mipsRusty Russell
Use the accessors rather than frobbing bits directly (the new versions are const). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com>
2009-09-24cpumask: arch_send_call_function_ipi_mask: mipsRusty Russell
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.

2009-07-03MIPS: CMP: activate CMP supportTim Anderson
Most of the CMP support was added before, this mostly correct compile problems but adds a platform specific translation for the interrupt number based on cpu number. Signed-off-by: Tim Anderson <tanderson@mvista.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-06-24MIPS: Build fix - include <linux/smp.h> into all smp_processor_id() users.Ralf Baechle
Some of the were relying into smp.h being dragged in by another header which of course is fragile. <asm/cpu-info.h> uses smp_processor_id() only in macros and including smp.h there leads to an include loop, so don't change cpu-info.h. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-12-13cpumask: change cpumask_scnprintf, cpumask_parse_user, cpulist_parse, and ↵Rusty Russell
cpulist_scnprintf to take pointers. Impact: change calling convention of existing cpumask APIs Most cpumask functions started with cpus_: these have been replaced by cpumask_ ones which take struct cpumask pointers as expected. These four functions don't have good replacement names; fortunately they're rarely used, so we just change them over.

2008-12-13cpumask: centralize cpu_online_map and cpu_possible_mapRusty Russell
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.
