Reverting these commits was reported to solve the problem for Alexander. Despite the reason for these commits, NUMA balancing is not the direct source of the problem. split_huge_page() expects the anon_vma lock to be exclusive to serialise the whole split operation. Ordinarily it is expected that the anon_vma lock would only be required when updating the avcs but THP also uses the anon_vma rwsem for collapse and split operations where the page lock or compound lock cannot be used (as the page is changing from base to THP or vice versa) and the page table locks are insufficient. This patch takes the anon_vma lock for write to serialise against parallel split_huge_page as THP expected before the conversion to rwsem.

Commit 5a505085 ("mm/rmap: Convert the struct anon_vma::mutex to an rwsem") turned anon_vma mutex to rwsem. However, the properly annotated nested locking in mm_take_all_locks() has been converted from mutex_lock_nest_lock(&anon_vma->root->mutex, &mm->mmap_sem); to down_write(&anon_vma->root->rwsem); which is incomplete, and causes the false positive report from lockdep below. Annotate the fact that mmap_sem is used as an outter lock to serialize taking of all the anon_vma rwsems at once no matter the order, using the down_write_nest_lock() primitive.

Currently free_all_bootmem_core ignores that node_min_pfn may be not multiple of BITS_PER_LONG. Eg commit 6dccdcbe ("mm: bootmem: fix checking the bitmap when finally freeing bootmem") shifts vec by lower bits of start instead of lower bits of idx. Also if (IS_ALIGNED(start, BITS_PER_LONG) && vec == ~0UL) assumes that vec bit 0 corresponds to start pfn, which is only true when node_min_pfn is a multiple of BITS_PER_LONG. Also loop in the else clause can double-free pages (e.g. with node_min_pfn == start == 1, map[0] == ~0 on 32-bit machine page 32 will be double-freed). This bug causes the following message during xtensa kernel boot: bootmem::free_all_bootmem_core nid=0 start=1 end=8000 BUG: Bad page state in process swapper pfn:00001 page:d04bd020 count:0 mapcount:-127 mapping: (null) index:0x2 page flags: 0x0() Call Trace: bad_page+0x8c/0x9c free_pages_prepare+0x5e/0x88 free_hot_cold_page+0xc/0xa0 __free_pages+0x24/0x38 __free_pages_bootmem+0x54/0x56 free_all_bootmem_core$part$11+0xeb/0x138 free_all_bootmem+0x46/0x58 mem_init+0x25/0xa4 start_kernel+0x11e/0x25c should_never_return+0x0/0x3be7 The fix is the following: - always align vec so that its bit 0 corresponds to start - provide BITS_PER_LONG bits in vec, if those bits are available in the map - don't free pages past next start position in the else clause.

The current calculation in pfn_to_bitidx assumes that (pfn - zone->zone_start_pfn) >> pageblock_order will return the same bit for all pfn in a pageblock. If zone_start_pfn is not aligned to pageblock_nr_pages, this may not always be correct. Consider the following with pageblock order = 10, zone start 2MB: pfn | pfn - zone start | (pfn - zone start) >> page block order ---------------------------------------------------------------- 0x26000 | 0x25e00 | 0x97 0x26100 | 0x25f00 | 0x97 0x26200 | 0x26000 | 0x98 0x26300 | 0x26100 | 0x98 This means that calling {get,set}_pageblock_migratetype on a single page will not set the migratetype for the full block. Fix this by rounding down zone_start_pfn when doing the bitidx calculation. For our use case, the effects of this bug were mostly tied to the fact that CMA allocations would either take a long time or fail to happen. Depending on the driver using CMA, this could result in anything from visual glitches to application failures. Signed-off-by:Laura Abbott <lauraa@codeaurora.org> Acked-by:

The tricky problem is this check: if (i++ >= max) icc (mis)optimizes this check as: if (++i > max) The check now becomes a no-op since max is MAX_ARG_STRINGS (0x7FFFFFFF). This is "allowed" by the C standard, assuming i++ never overflows, because signed integer overflow is undefined behavior. This optimization effectively reverts the previous commit 362e6663 ("exec.c, compat.c: fix count(), compat_count() bounds checking") that tries to fix the check. This patch simply moves ++ after the check. Signed-off-by:

when run the folloing command under shell, it will return error sh/$ echo 1 > /proc/sys/vm/compact_memory sh/$ sh: write error: Bad address After strace, I found the following log: ... write(1, "1\n", 2) = 3 write(1, "", 4294967295) = -1 EFAULT (Bad address) write(2, "echo: write error: Bad address\n", 31echo: write error: Bad address ) = 31 This tells system return 3(COMPACT_COMPLETE) after write data to compact_memory. The fix is to make the system just return 0 instead 3(COMPACT_COMPLETE) from sysctl_compaction_handler after compaction_nodes finished. Signed-off-by:

The memmove span covers from (next+1) to the end of the array, and the index of next is (i+1), so the index of (next+1) is (i+2). So the size of remaining array elements is (type->cnt - (i + 2)). Since the remaining elements of the memblock array are move forward by one element and there is only one additional element caused by this bug. So there won't be any write overflow here but read overflow. It may read one more element out of the array address if the array happens to be full. Commonly it doesn't matter at all but if the array happens to be located at the end a memblock, it may cause a invalid read operation for the physical address doesn't exist. There are 2 *happens to be* here, so I think the probability is quite low, I don't know if any guy is haunted by this bug before. Mostly I think it's user-invisible. Signed-off-by:

This was leading to a strange behaviour when using the fbcon driver on top of this one: the letters were in the right order, but each letter had a vertical symmetry. This was because the addressing was right for the byte, but the addressing of each individual bit was inverted. Signed-off-by:

Hugh Dickins pointed out that migrate_misplaced_transhuge_page() does not check page_count before migrating like base page migration and khugepage. He could not see why this was safe and he is right. The potential impact of the bug is avoided due to the limitations of NUMA balancing. The page_mapcount() check ensures that only a single address space is using this page and as THPs are typically private it should not be possible for another address space to fault it in parallel. If the address space has one associated task then it's difficult to have both a GUP pin and be referencing the page at the same time. If there are multiple tasks then a buggy scenario requires that another thread be accessing the page while the direct IO is in flight. This is dodgy behaviour as there is a possibility of corruption with or without THP migration. It would be While we happen to be safe for the most part it is shoddy to depend on such "safety" so this patch checks the page count similar to anonymous pages. Note that this does not mean that the page_mapcount() check can go away. If we were to remove the page_mapcount() check the the THP would have to be unmapped from all referencing PTEs, replaced with migration PTEs and restored properly afterwards. Signed-off-by:

In some cases, free_irq_cpu_rmap() is called while holding a lock (eg rtnl). This can lead to deadlocks, because it invokes flush_scheduled_work() which ends up waiting for whole system workqueue to flush, but some pending works might try to acquire the lock we are already holding. This commit uses reference-counting to replace irq_run_affinity_notifiers(). It also removes irq_run_affinity_notifiers() altogether.

The latest change to allow trace options to be set on the command line also broke the trace_options file. The zeroing of the last byte of the option name that is echoed into the trace_option file was removed with the consolidation of some of the code. The compare between the option and what was written to the trace_options file fails because the string holding the data written doesn't terminate with a null character. A zero needs to be added to the end of the string copied from user space. Signed-off-by:Steven Rostedt <rostedt@goodmis.org>

It's a bit big but its mostly exynos license fix ups and I'd rather not hold those up since its legally stuff. Radeon has a couple of fixes from dma engine work, TTM is just a locking fix, and dma-buf fix has been hanging around and I finally got a chance to review it." * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: (30 commits) drm/ttm: fix fence locking in ttm_buffer_object_transfer drm/prime: drop reference on imported dma-buf come from gem drm/radeon: add quirk for d3 delay during switcheroo poweron for apple macbooks drm/exynos: move finish page flip to a common place drm/exynos: fimd: modify condition in fimd resume drm/radeon: fix DMA CS parser for r6xx linear copy packet drm/radeon: split r6xx and r7xx copy_dma functions drm/exynos: Use devm_clk_get in exynos_drm_gsc.c drm/exynos: Remove redundant NULL check in exynos_drm_gsc.c drm/exynos: Remove explicit freeing using devm_* APIs in exynos_drm_gsc.c drm/exynos: Use devm_clk_get in exynos_drm_rotator.c drm/exynos: Remove redundant NULL check in exynos_drm_rotator.c drm/exynos: Remove unnecessary devm_* freeing APIs in exynos_drm_rotator.c drm/exynos: Use devm_clk_get in exynos_drm_fimc.c drm/exynos: Remove redundant NULL check drm/exynos: Remove explicit freeing using devm_* APIs in exynos_drm_fimc.c drm/exynos: Use devm_kzalloc in exynos_drm_ipp.c drm/exynos: fix gem buffer allocation type checking drm/exynos: remove needless parenthesis. drm/exynos: fix incorrect interrupt induced by m2m operation. ...
