m32r: delete __cpuinit usage from all m32r files

2013-07-14T23:36:55Z

The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) are flagged as __cpuinit -- so if we remove the __cpuinit from arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the arch/m32r uses of the __cpuinit macros from all C files. Currently m32r does not have any __CPUINIT used in assembly files.

ARCH: drivers remove __dev* attributes.

2013-01-03T23:57:13Z

This fixes up all of the smaller arches that had __dev* markings for their platform-specific drivers. CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

m32r: convert cpumask api

2011-05-27T00:12:32Z

We plan to remove cpus_xx() old cpumask APIs later. Also, we plan to change mm_cpu_mask() implementation, allocate only nr_cpu_ids, thus *mm_cpu_mask() is dangerous operation. Then, this patch convert them. Signed-off-by: KOSAKI Motohiro Cc: Hirokazu Takata Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

cpumask: centralize cpu_online_map and cpu_possible_map

2008-12-13T10:49:41Z

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.
