* sh: delete __cpuinit usage from all sh filesPaul Gortmaker2013-07-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/sh uses of the __cpuinit macros from all C files. Currently sh does not have any __CPUINIT used in assembly files.

* sh: Tidy CPU probing and fixup section annotations.Paul Mundt2010-04-211-3/+1
| | | | | | | | This does a detect_cpu_and_cache_system() -> cpu_probe() rename, tidies up the unused return value, and stuffs it under __cpuinit in preparation for CPU hotplug. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Track the CPU family in sh_cpuinfo.Paul Mundt2009-08-151-0/+2
| | | | | | | | | | This adds a family member to struct sh_cpuinfo, which allows us to fall back more on the probe routines to work out what sort of subtype we are running on. This will be used by the CPU cache initialization code in order to first do family-level initialization, followed by subtype-level optimizations. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
