3a6ab5c Thierry Reding14 December 2018, 22:17:24 UTCscripts/spdxcheck.py: always open files in binary mode The spdxcheck script currently falls over when confronted with a binary file (such as Documentation/logo.gif). To avoid that, always open files in binary mode and decode line-by-line, ignoring encoding errors. One tricky case is when piping data into the script and reading it from standard input. By default, standard input will be opened in text mode, so we need to reopen it in binary mode. The breakage only happens with python3 and results in a UnicodeDecodeError (according to Uwe).

f1733a1 Qian Cai14 December 2018, 22:17:20 UTCcheckstack.pl: fix for aarch64 There is actually a space after "sp," like this, ffff2000080813c8: a9bb7bfd stp x29, x30, [sp, #-80]! Right now, checkstack.pl isn't able to print anything on aarch64, because it won't be able to match the stating objdump line of a function due to this missing space. Hence, it displays every stack as zero-size. After this patch, checkpatch.pl is able to match the start of a function's objdump, and is then able to calculate each function's stack correctly.

61c6de6 Piotr Jaroszynski14 December 2018, 22:17:14 UTCfs/iomap.c: get/put the page in iomap_page_create/release() migrate_page_move_mapping() expects pages with private data set to have a page_count elevated by 1. This is what used to happen for xfs through the buffer_heads code before the switch to iomap in commit 82cb14175e7d ("xfs: add support for sub-pagesize writeback without buffer_heads"). Not having the count elevated causes move_pages() to fail on memory mapped files coming from xfs. Make iomap compatible with the migrate_page_move_mapping() assumption by elevating the page count as part of iomap_page_create() and lowering it in iomap_page_release(). It causes the move_pages() syscall to misbehave on memory mapped files from xfs. It does not not move any pages, which I suppose is "just" a perf issue, but it also ends up returning a positive number which is out of spec for the syscall. Talking to Michal Hocko, it sounds like returning positive numbers might be a necessary update to move_pages() anyway though (https://lkml.kernel.org/r/20181116114955.GJ14706@dhcp22.suse.cz). I only hit this in tests that verify that move_pages() actually moved the pages. The test also got confused by the positive return from move_pages() (it got treated as a success as positive numbers were not expected and not handled) making it a bit harder to track down what's going on.

8ace22b Yongkai Wu14 December 2018, 22:17:10 UTChugetlbfs: call VM_BUG_ON_PAGE earlier in free_huge_page() A stack trace was triggered by VM_BUG_ON_PAGE(page_mapcount(page), page) in free_huge_page(). Unfortunately, the page->mapping field was set to NULL before this test. This made it more difficult to determine the root cause of the problem. Move the VM_BUG_ON_PAGE tests earlier in the function so that if they do trigger more information is present in the page struct.

5b52609 Mike Rapoport14 December 2018, 22:16:50 UTCalpha: fix hang caused by the bootmem removal The conversion of alpha to memblock as the early memory manager caused boot to hang as described at [1]. The issue is caused because for CONFIG_DISCTONTIGMEM=y case, memblock_add() is called using memory start PFN that had been rounded down to the nearest 8Mb and it caused memblock to see more memory that is actually present in the system. Besides, memblock allocates memory from high addresses while bootmem was using low memory, which broke the assumption that early allocations are always accessible by the hardware. This patch ensures that memblock_add() is using the correct PFN for the memory start and forces memblock to use bottom-up allocations.

28adac6 Daniel Vetter10 December 2018, 10:30:01 UTCMAINTAINERS: Daniel for drm co-maintainer lkml and Linus gained a CoC, and it's serious this time. Which means my no 1 reason for declining to officially step up as drm maintainer is gone, and I didn't find any new good excuse. I chatted with a few people in private already, and the biggest concern is that I mislay my community hat and start running around with my intel hat only. Or some other convenient abuse of trust. That's why this patch doesn't just need a lot of acks that mean "yeah seems fine to me", but a lot of acks that mean "yeah we'll tell you when you're over the line and usurp you from that comfy chair if you don't get it". Which I think we've been done a fairly good job here at dri-devel in general, but better to be clear. Rough idea is that I'll do this for maybe 2-3 years, helping Dave figure out a group model for drm overall. And getting the tooling and infrastructure for that off the ground. Then step down again because some other shiny thing that needs chasing. Of course as plans tend to do, this one will probably pan out a bit different in reality.

It wasn't realized until it became clear that userspace response to the event raced with the actual state change that the event was meant to notify about. Fix this by first updating internal thin-pool state to reflect what the DM event is being issued about. This fixes a long-standing racey/buggy userspace device-mapper-test-suite 'resize_io' test that would get an event but not find the state it was looking for -- so it would just go on to hang because no other events caused the test to reevaluate the thin-pool's state.

6323817 Brian Norris05 December 2018, 18:16:57 UTCRevert "drm/rockchip: Allow driver to be shutdown on reboot/kexec" This reverts commit 7f3ef5dedb146e3d5063b6845781ad1bb59b92b5. It causes new warnings [1] on shutdown when running the Google Kevin or Scarlet (RK3399) boards under Chrome OS. Presumably our usage of DRM is different than what Marc and Heiko test. We're looking at a different approach (e.g., [2]) to replace this, but IMO the revert should be taken first, as it already propagated to -stable.

Commit '88ba95bedb79 ("backlight: pwm_bl: Compute brightness of LED linearly to human eye")' allows the possibility to compute a default brightness table when there isn't the brightness-levels property in the DT. Unfortunately the changes made broke the pwm backlight for the non-DT boards. Usually, the non-DT boards don't pass the brightness levels via platform data, instead, it sets the max_brightness in their platform data and the driver calculates the level without a table. The offending patch assumed that when there is no brightness levels table we should create one, but this is clearly wrong for the non-DT case. After this patch the code handles the DT and the non-DT case taking in consideration also if max_brightness is set or not.

e30fbc3 Michael Chan09 December 2018, 12:01:02 UTCbnxt_en: Fix _bnxt_get_max_rings() for 57500 chips. The CP rings are accounted differently on the new 57500 chips. There must be enough CP rings for the sum of RX and TX rings on the new chips. The current logic may be over-estimating the RX and TX rings. The output parameter max_cp should be the maximum NQs capped by MSIX vectors available for networking in the context of 57500 chips. The existing code which uses CMPL rings capped by the MSIX vectors works most of the time but is not always correct. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

c0b8cda Michael Chan09 December 2018, 12:01:01 UTCbnxt_en: Fix NQ/CP rings accounting on the new 57500 chips. The new 57500 chips have introduced the NQ structure in addition to the existing CP rings in all chips. We need to introduce a new bnxt_nq_rings_in_use(). On legacy chips, the 2 functions are the same and one will just call the other. On the new chips, they refer to the 2 separate ring structures. The new function is now called to determine the resource (NQ or CP rings) associated with MSIX that are in use. On 57500 chips, the RDMA driver does not use the CP rings so we don't need to do the subtraction adjustment.

75720e6 Michael Chan09 December 2018, 12:01:00 UTCbnxt_en: Keep track of reserved IRQs. The new 57500 chips use 1 NQ per MSIX vector, whereas legacy chips use 1 CP ring per MSIX vector. To better unify this, add a resv_irqs field to struct bnxt_hw_resc. On legacy chips, we initialize resv_irqs with resv_cp_rings. On new chips, we initialize it with the allocated MSIX resources.

804fba4 Michael Chan09 December 2018, 12:00:59 UTCbnxt_en: Fix CNP CoS queue regression. Recent changes to support the 57500 devices have created this regression. The bnxt_hwrm_queue_qportcfg() call was moved to be called earlier before the RDMA support was determined, causing the CoS queues configuration to be set before knowing whether RDMA was supported or not. Fix it by moving it to the right place right after RDMA support is determined. Fixes: 98f04cf0f1fc ("bnxt_en: Check context memory requirements from firmware.")
