2009-03-16cpumask: use mm_cpumask() wrapper: sparcRusty Russell
Makes code futureproof against the impending change to mm->cpu_vm_mask. It's also a chance to use the new cpumask_ ops which take a pointer (the older ones are deprecated, but there's no hurry for arch code). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-03-16cpumask: prepare for iterators to only go to nr_cpu_ids/nr_cpumask_bits.: sparcRusty Russell
Impact: cleanup, futureproof In fact, all cpumask ops will only be valid (in general) for bit numbers < nr_cpu_ids. So use that instead of NR_CPUS in various places. This is always safe: no cpu number can be >= nr_cpu_ids, and nr_cpu_ids is initialized to NR_CPUS at boot.

2009-03-16cpumask: Use accessors code: sparcRusty Russell
Impact: use new API Use the accessors rather than frobbing bits directly. Most of this is in arch code I haven't even compiled, but it is mostly straightforward. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com>

2008-12-04sparc: prepare kernel/ for unificationSam Ravnborg
o sparc32 files with identical names to sparc64 renamed to <name>_32.S o introduced a few Kconfig helpers to simplify Makefile logic o refactored Makefile to prepare for unification - use obj-$(CONFIG_SPARC32) for sparc32 specific files - use <name>_$(BITS) for files where sparc64 has a _64 variant - sparc64 directly include a few files where sparc32 builds them, refer to these files directly (no BITS) - sneaked in -Werror as used by sparc64 o modified sparc/Makefile to use the new names for head/init_task Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.
