2013-02-04sanitize rt_sigaction() situation a bitAl Viro1-0/+6
Switch from __ARCH_WANT_SYS_RT_SIGACTION to opposite (!CONFIG_ODD_RT_SIGACTION); the only two architectures that need it are alpha and sparc. The reason for use of CONFIG_... instead of __ARCH_... is that it's needed only kernel-side and doing it that way avoids a mess with include order on many architectures.

2013-02-03Merge branch 'delete-wanrouter' of ↵David S. Miller3-264/+4
git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux Paul Gortmaker says: ==================== The removal of wanrouter code was originally listed in the (now gone) feature removal file since May 2012, and an RFC of the deletion was posted[1] in late 2012. The overall concept was given an OK, but defconfig contamination, build failures, etc. meant that it didn't quite make it into mainline for 3.8. Since that time, Dan discovered (via code audit) a runtime bug that proves nobody has been using this for over four years[2]. With that new information, I think it makes sense for someone to follow through on Joe's original RFC and get this done for the 3.9 release. In addition to resolving the build failures of the RFC by keeping stub headers, this also splits the change into two parts, just like the token ring removal did. Part #1 decouples the mainline kernel from the expired subsystem, and part #2 does the large scale deletion of the subsystem content. The advantage of the above, is that a "git blame" will never lead you to a 4000+ line deletion commit. The large scale deletion will never show up in a "git blame" and hence the same advantages that we get from the "--irreversible-delete" in the review stage of "git format-patch" are also embedded into the git history itself. This may seem like a moot point to some, but for those who spend a considerable amount of time data mining in the git history, this is probably worth doing. I have done build tests of all[mod/yes]config for both the stage 1 (Makefile and Kconfig) and stage 2 (full driver delete) as a sanity check, and the issues with the previously posted RFC should be gone. Speaking of "--irreversible-delete" -- these patches were created with that option, so if you want to use them locally, you are going to have to pull (location below) the content instead of doing a "git am" of the mailed out content.

2013-02-02cpufreq: Simplify __cpufreq_remove_dev()Viresh Kumar1-5/+9
__cpufreq_remove_dev() is called on multiple occasions: cpufreq_driver unregister and cpu removals. Current implementation of this routine is overly complex without much need. If the cpu to be removed is the policy->cpu, we remove the policy first and add all other cpus again from policy->cpus and then finally call __cpufreq_remove_dev() again to remove the cpu to be deleted. Haahhhh.. There exist a simple solution to removal of a cpu: - Simply use the old policy structure - update its fields like: policy->cpu, etc. - notify any users of cpufreq, which depend on changing policy->cpu Hence this patch, which tries to implement the above theory. It is tested well by myself on ARM big.LITTLE TC2 SoC, which has 5 cores (2 A15 and 3 A7). Both A15's share same struct policy and all A7's share same policy structure.

2013-02-01slab: Use common kmalloc_index/kmalloc_size functionsChristoph Lameter2-80/+12
Make slab use the common functions. We can get rid of a lot of old ugly stuff as a results. Among them the sizes array and the weird include/linux/kmalloc_sizes file and some pretty bad #include statements in slab_def.h. The one thing that is different in slab is that the 32 byte cache will also be created for arches that have page sizes larger than 4K. There are numerous smaller allocations that SLOB and SLUB can handle better because of their support for smaller allocation sizes so lets keep the 32 byte slab also for arches with > 4K pages.

2013-02-01wanrouter: delete now orphaned header content, files/driversPaul Gortmaker3-264/+4
The wanrouter support was identified earlier as unused for years, and so the previous commit totally decoupled it from the kernel, leaving the related wanrouter files present, but totally inert. Here we take the final step in that cleanup, by doing a wholesale removal of these files. The two step process is used so that the large deletion is decoupled from the git history of files that we still care about. The drivers deleted here all were dependent on the Kconfig setting CONFIG_WAN_ROUTER_DRIVERS. A stub wanrouter.h header (kernel & uapi) are left behind so that drivers/isdn/i4l/isdn_x25iface.c continues to compile, and so that we don't accidentally break userspace that expected these defines.
