On 32-bit machines, we can't divide 64-bit integers: drivers/gpu/drm/arm/malidp_crtc.o: In function `malidp_crtc_atomic_check': malidp_crtc.c:(.text.malidp_crtc_atomic_check+0x3c0): undefined reference to `__aeabi_uldivmod' malidp_crtc.c:(.text.malidp_crtc_atomic_check+0x3dc): undefined reference to `__aeabi_uldivmod' This calls the div_u64 function explicitly instead.

When downscaling, mclk needs to be sufficiently higher than pxlclk in order to be able to fetch the higher-resolution data and produce output pixels. When not scaling, or when upscaling, mclk can be equal to pxlclk. Since the driver doesn't control mclk, just ensure that the requirement is satisfied with the current clock rate. Signed-off-by:

Add gamma via the DRM GAMMA_LUT/GAMMA_LUT_SIZE CRTC properties. The expected LUT size is 4096 in order to produce as accurate a set of segments as possible. This version uses only the green channel's gamma curve to set the hardware curve on DP550/650. For the sake of simplicity, it uses the same table of coefficients for all 3 curves on DP500.

Seeing the kunmap_atomic dma_buf_ops share the same name with a macro in highmem.h, the former can be aliased if any dma-buf user includes that header. I'm personally trying to include highmem.h inside scatterlist.h and this breaks the dma-buf code proper. Christoph Hellwig suggested [1] renaming it and pushing this patch ASAP. To maintain consistency I've renamed all four of kmap* and kunmap* to be map* and unmap*. (Even though only kmap_atomic presently conflicts.)

Pull ftrace fix from Steven Rostedt: "While rewriting the function probe code, I stumbled over a long standing bug. This bug has been there sinc function tracing was added way back when. But my new development depends on this bug being fixed, and it should be fixed regardless as it causes ftrace to disable itself when triggered, and a reboot is required to enable it again. The bug is that the function probe does not disable itself properly if there's another probe of its type still enabled. For example: # cd /sys/kernel/debug/tracing # echo schedule:traceoff > set_ftrace_filter # echo do_IRQ:traceoff > set_ftrace_filter # echo \!do_IRQ:traceoff > /debug/tracing/set_ftrace_filter # echo do_IRQ:traceoff > set_ftrace_filter The above registers two traceoff probes (one for schedule and one for do_IRQ, and then removes do_IRQ. But since there still exists one for schedule, it is not done properly. When adding do_IRQ back, the breakage in the accounting is noticed by the ftrace self tests, and it causes a warning and disables ftrace" * tag 'trace-v4.11-rc5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Fix removing of second function probe

Pull nvdimm fixes from Dan Williams: "A small crop of lockdep, sleeping while atomic, and other fixes / band-aids in advance of the full-blown reworks targeting the next merge window. The largest change here is "libnvdimm: fix blk free space accounting" which deletes a pile of buggy code that better testing would have caught before merging. The next change that is borderline too big for a late rc is switching the device-dax locking from rcu to srcu, I couldn't think of a smaller way to make that fix. The __copy_user_nocache fix will have a full replacement in 4.12 to move those pmem special case considerations into the pmem driver. The "libnvdimm: band aid btt vs clear poison locking" commit admits that our error clearing support for btt went in broken, so we just disable it in 4.11 and -stable. A replacement / full fix is in the pipeline for 4.12 Some of these would have been caught earlier had DEBUG_ATOMIC_SLEEP been enabled on my development station. I wonder if we should have: config DEBUG_ATOMIC_SLEEP default PROVE_LOCKING ...since I mistakenly thought I got both with PROVE_LOCKING=y.

Normal pathname lookup doesn't allow empty pathnames, but using AT_EMPTY_PATH (with name_to_handle_at() or fstatat(), for example) you can trigger an empty pathname lookup. And not only is the RCU lookup in that case entirely unnecessary (because we'll obviously immediately finalize the end result), it is actively wrong. Why? An empth path is a special case that will return the original 'dirfd' dentry - and that dentry may not actually be RCU-free'd, resulting in a potential use-after-free if we were to initialize the path lazily under the RCU read lock and depend on complete_walk() finalizing the dentry.

The patch 554bfece ("parisc: Fix access fault handling in pa_memcpy()") reimplements the pa_memcpy function. Unfortunatelly, it makes the kernel unbootable. The crash happens in the function ide_complete_cmd where memcpy is called with the same source and destination address. This patch fixes a few bugs in pa_memcpy: * When jumping to .Lcopy_loop_16 for the first time, don't skip the instruction "ldi 31,t0" (this bug made the kernel unbootable) * Use the COND macro when comparing length, so that the comparison is 64-bit (a theoretical issue, in case the length is greater than 0xffffffff) * Don't use the COND macro after the "extru" instruction (the PA-RISC specification says that the upper 32-bits of extru result are undefined, although they are set to zero in practice) * Fix exception addresses in .Lcopy16_fault and .Lcopy8_fault * Rename .Lcopy_loop_4 to .Lcopy_loop_8 (so that it is consistent with .Lcopy8_fault) Cc: <stable@vger.kernel.org> # v4.9+ Fixes: 554bfece ("parisc: Fix access fault handling in pa_memcpy()") Signed-off-by:
