git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup From Tony Lindgren: Removal of unused omap defines via Paul Walmsley <paul@pwsan.com>: This series removes the currently-unused PRCM macros from arch/arm/mach-omap2. Basic test logs are available at: http://www.pwsan.com/omap/testlogs/drop_unused_prcm_macros_v3.11-rc/20130721211401/ Once, years ago, we thought that it would be good to document the PRCM register bits in the Linux codebase. Most folks in the broader community did not have access to the same documentation, so we thought that they might be able to use these bits to fix bugs and improve the code. We were also able to autogenerate most of these macros, so it was thought that defining them in advance would reduce the risk of error, inconsistencies, and merge conflicts caused when patch sets incrementally defined them by hand. Well, nice thoughts. But the first rationale was rendered partially obsolete when TI started to release public TRM documentation PDFs at some point in the OMAP3 timeframe. (Despite their weaknesses, TI's public OMAP TRMs remain the most useful public documentation available for any ARM Linux SoC -- at least to the extent of my knowledge.) And then the current Linux development tropism towards development-by-negative-diffstat obliterated the remainder of the above two philosophies. So, for the few, the masochistic, out there who wish to continue developing TI PRCM code, I would ask that you resurrect any additionally-needed macros from these commits, rather than writing them manually. Purely for the sake of a pleasant atavism, perhaps; the way one appreciates a used bookstore, or a video rental store... And thanks to the upstream maintainers for being patient while we adjust. * tag 'omap-for-v3.12/cleanup-unused-defines' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP5: PRM/CM: Cleanup unused header ARM: OMAP4: PRM/CM: Cleanup unused header ARM: OMAP3: PRM/CM: Cleanup unused header ARM: OMAP2: PRM/CM: Cleanup unused header Signed-off-by: Olof Johansson <olof@lixom.net>

Pull drm fix from Dave Airlie: "Just a quick fix that a few people have reported, be nice to have in asap" The drm tree seems to be very confused about 64-bit divides. Here it uses a slow 64-by-64 bit divide to divide by a small constant. Oh well. Doesn't look performance-critical, just stupid. * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: drm/radeon: fix 64 bit divide in SI spm code
2013-08-04tmpfs: fix SEEK_DATA/SEEK_HOLE regressionHugh Dickins1-1/+2
Commit 46a1c2c7ae53 ("vfs: export lseek_execute() to modules") broke the tmpfs SEEK_DATA/SEEK_HOLE implementation, because vfs_setpos() converts the carefully prepared -ENXIO to -EINVAL. Other filesystems avoid it in error cases: do the same in tmpfs.
