* sparc: drop use of extern for prototypes in arch/sparc/include/asmSam Ravnborg2014-05-1879-706/+711
| | | | | | | | | | | Drop extern for all prototypes and adjust alignment of parameters as required after the removal. In a few rare cases adjust linelength to conform to maximum 80 chars, and likewise in a few rare cases adjust alignment of parameters to static functions.

* sparc32: drop tadpole specific codeSam Ravnborg2014-05-184-135/+0
| | | | | | | | | | | | | tadpole.c assigned cpu_pwr_save based on the current configuration. The rest of the tadpole.c file was only used if cpu_pwr_save was dereferenced. But this variable was never dereferenced - and I went back to a 2.6.12 kernel to check (from June 2005) - and not even then was it used. Drop this code as it has not been in use for ~10 years.

* sparc64: remove cast from output constraints in math asm statementsSam Ravnborg2014-05-181-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | The following asm statements generated a sparse warning: asm("addcc \n\t" : "=r" (((USItype)(r2))) warning: asm output is not an lvalue When asking on the sparse mailing list Linus replyed: " Those casts to (USItype) are all pointless to begin with (since the values are of that type already!) and they mean that the expression isn't something you can assign to (lvalue). " In the math emulation code drop all casts in the output parts of the asm statements. This fixes a lot of "warning: asm output is not an lvalue" sparse warnings in math_64.c.

Instead, the correct and race-free way of performing the callback registration is: cpu_notifier_register_begin(); for_each_online_cpu(cpu) init_cpu(cpu); /* Note the use of the double underscored version of the API */ __register_cpu_notifier(&foobar_cpu_notifier); cpu_notifier_register_done(); Fix the sysfs code in sparc by using this latter form of callback registration.

Naturally, there are places where vfs rules don't fit and nasty hacks, such as credential switching or lock dance interleaving inode mutex and cgroup_mutex with object serial number comparison thrown in to decide whether the operation is actually necessary, needed to be employed. After conversion to kernfs, internal object lifetime and locking rules are mostly isolated from vfs interactions allowing shedding of several nasty hacks and overall simplification. This will also allow implmentation of operations which may affect multiple cgroups which weren't possible before as it would have required nesting i_mutexes. - Various simplifications including dropping of module support, easier cgroup name/path handling, simplified cgroup file type handling and task_cg_lists optimization. - Prepatory changes for the planned unified hierarchy, which is still a patchset away from being actually operational. The dummy hierarchy is updated to serve as the default unified hierarchy. Controllers which aren't claimed by other hierarchies are associated with it, which BTW was what the dummy hierarchy was for anyway. - Various fixes from Li and others. This pull request includes some patches to add missing slab.h to various subsystems. This was triggered xattr.h include removal from cgroup.h. cgroup.h indirectly got included a lot of files which brought in xattr.h which brought in slab.h.
