2017-05-19drm/pl111: Register the clock divider and use it.Eric Anholt5-24/+163
This is required for the panel to work on bcm911360, where CLCDCLK is the fixed 200Mhz AXI41 clock. The rate set is still passed up to the CLCDCLK, for platforms that have a settable rate on that one. v2: Set SET_RATE_PARENT (caught by Linus Walleij), depend on COMMON_CLK. v3: Mark the clk_ops static (caught by Stephen).

2017-05-18drm: drop drm_[cm]alloc* helpersMichal Hocko26-122/+128
Now that drm_[cm]alloc* helpers are simple one line wrappers around kvmalloc_array and drm_free_large is just kvfree alias we can drop them and replace by their native forms. This shouldn't introduce any functional change.

2017-05-18drm: replace drm_[cm]alloc* by kvmalloc alternativesMichal Hocko1-78/+0
drm_[cm]alloc* has grown their own kvmalloc with vmalloc fallback implementations. MM has grown kvmalloc* helpers in the meantime. Let's use those because it a) reduces the code and b) MM has a better idea how to implement fallbacks (e.g. do not vmalloc before kmalloc is tried with __GFP_NORETRY). drm_calloc_large needs to get __GFP_ZERO explicitly but it is the same thing as kvmalloc_array in principle.

2017-05-15drm/dp: Wait up all outstanding tx waitersChris Wilson1-3/+3
As we can have multiple tx in the queue, with individual waiters, make sure that all are woken when any state changes (so that we are sure the right owner of the txmsg is woken).

2017-05-15drm/dp: Read the tx msg state once after checking for an eventChris Wilson1-4/+4
Both as an exercise to document that we are reading the state outside of the appropriate mutex and to ensure that we only read the value once before the multiple comparisons, use READ_ONCE.

Finally, OOM happens. The problem is that get_scan_count determines nr_to_scan with eligible zones so although priority drops to zero, it couldn't reclaim any pages if the LRU contains mostly ineligible pages. get_scan_count: size = lruvec_lru_size(lruvec, lru, sc->reclaim_idx); size = size >> sc->priority; Assumes sc->priority is 0 and LRU list is as follows. N-N-N-N-H-H-H-H-H-H-H-H-H-H-H-H-H-H-H-H (Ie, small eligible pages are in the head of LRU but others are almost ineligible pages) In that case, size becomes 4 so VM want to scan 4 pages but 4 pages from tail of the LRU are not eligible pages. If get_scan_count counts skipped pages, it doesn't reclaim any pages remained after scanning 4 pages so it ends up OOM happening. This patch makes isolate_lru_pages try to scan pages until it encounters eligible zones's pages. [akpm@linux-foundation.org: clean up mind-bending `for' statement.

2017-05-13mm, thp: copying user pages must schedule on collapseDavid Rientjes1-4/+3
We have encountered need_resched warnings in __collapse_huge_page_copy() while doing {clear,copy}_user_highpage() over HPAGE_PMD_NR source pages. mm->mmap_sem is held for write, but the iteration is well bounded. Reschedule as needed.
