2012-10-28percpu-rw-semaphores: use rcu_read_lock_schedMikulas Patocka1-4/+4
Use rcu_read_lock_sched / rcu_read_unlock_sched / synchronize_sched instead of rcu_read_lock / rcu_read_unlock / synchronize_rcu. This is an optimization. The RCU-protected region is very small, so there will be no latency problems if we disable preempt in this region. So we use rcu_read_lock_sched / rcu_read_unlock_sched that translates to preempt_disable / preempt_disable. It is smaller (and supposedly faster) than preemptible rcu_read_lock / rcu_read_unlock.

2012-10-28percpu-rw-semaphores: use light/heavy barriersMikulas Patocka1-13/+7
This patch introduces new barrier pair light_mb() and heavy_mb() for percpu rw semaphores. This patch fixes a bug in percpu-rw-semaphores where a barrier was missing in percpu_up_write. This patch improves performance on the read path of percpu-rw-semaphores: on non-x86 cpus, there was a smp_mb() in percpu_up_read. This patch changes it to a compiler barrier and removes the "#if defined(X86) ..." condition.

2012-10-19iio: Add some helper macros for unit conversionLars-Peter Clausen1-0/+16
Some datasheets use a different unit to specify the channel scale than what IIO expects it to be. This patch adds two helper macros which allow to convert units commonly used in datasheets to IIO units: * acceleration: g -> meter / second**2 * angular velocity: degree (/ second) -> rad (/ second) This makes it much more convenient to specify and also easier to verify a channel's scale attribute.

Pull media fixes from Mauro Carvalho Chehab: "Media fixes for: - one Kconfig fix patch; - one patch fixing DocBook breakage due to the drivers/media UAPI changes; - the remaining UAPI media changes (DVB API). I'm aware that is is a little late for the UAPI renames for the DVB API, but IMHO, it is better to merge it for 3.7, due to two reasons: 1) There is a major rename at 3.7 (not only uapi changes, but also the entire media drivers were reorganized on 3.7, in order to simplify the Kconfig logic, and easy drivers selection, especially for hybrid devices). By confining all those renames there at 3.7 it will cause all the harm at for media developers on just one shot. Stable backports upstream and at distros will likely welcome it as well, as they won't need to check what changed on 3.7 and what was postponed for on 3.8. 2) The V4L2 DocBook Makefile creates a cross-reference between the media API headers and the specs. This helps us _a_lot_ to be sure that all API improvements are properly documented. Every time a header changes from one place to another, DocBook/media/Makefile needs to be patched.

2012-10-17UAPI: Remove empty non-UAPI Kbuild filesDavid Howells18-17/+0
Remove non-UAPI Kbuild files that have become empty as a result of UAPI disintegration. They used to have only header-y lines in them and those have now moved to the Kbuild files in the corresponding uapi/ directories. Possibly these should not be removed but rather have a comment inserted to say they are intentionally left blank. This would make it easier to add generated header lines in future without having to restore the infrastructure. Note that at this point not all the UAPI disintegration parts have been merged, so it is likely that more empty Kbuild files will turn up. It is probably necessary to make the files non-empty to prevent the patch program from automatically deleting them when it reduces them to nothing. Signed-off-by: David Howells <dhowells@redhat.com>

2012-10-16FRV: Fix linux/elf-fdpic.hDavid Howells1-0/+51
It seems I accidentally switched the guard on linux/elf-fdpic.h from #ifdef __KERNEL__ to #ifndef __KERNEL__ when attempting to expand the guarded region to cover the elf_fdpic_params struct when doing the UAPI split - with the result that the struct became unavailable to kernel code. Move incorrectly guarded bits back to the kernelspace header. Whilst we're at it, the __KERNEL__ guards can be deleted as they're no longer necessary.

Pull UAPI disintegration for include/linux/{,byteorder/}*.h from David Howells: "The patches contained herein do the following: (1) Remove kernel-only stuff in linux/ppp-comp.h from the UAPI. I checked this with Paul Mackerras before I created the patch and he suggested some extra bits to unexport. (2) Remove linux/blk_types.h entirely from the UAPI as none of it is userspace applicable, and remove from the UAPI that part of linux/fs.h that was the reason for linux/blk_types.h being exported in the first place. I discussed this with Jens Axboe before creating the patch. (3) The big patch of the series to disintegrate include/linux/*.h as a unit. This could be split up, though there would be collisions in moving stuff between the two Kbuild files when the parts are merged as that file is sorted alphabetically rather than being grouped by subsystem. Of this set of headers, 17 files have changed in the UAPI exported region since the 4th and only 8 since the 9th so there isn't much change in this area - as one might expect. It should be pretty obvious and straightforward if it does come to fixing up: stuff in __KERNEL__ guards stays where it is and stuff outside moves to the same file in the include/uapi/linux/ directory. If a new file appears then things get a bit more complicated as the "headers +=" line has to move to include/uapi/linux/Kbuild. Only one new file has appeared since the 9th and I judge this type of event relatively unlikely. (4) A patch to disintegrate include/linux/byteorder/*.h as a unit.
