      Revert "bdi: add a user-tunable cpu_list for the bdi flusher threads" · 9360b536
      Linus Torvalds authored
      This reverts commit 8fa72d23.
      
      People disagree about how this should be done, so let's revert this for
      now so that nobody starts using the new tuning interface.  Tejun is
      thinking about a more generic interface for thread pool affinity.

      Merge branch 'for-3.8/core' of git://git.kernel.dk/linux-block · 60da5bf4
      Linus Torvalds authored
      Pull block layer core updates from Jens Axboe:
       "Here are the core block IO bits for 3.8.  The branch contains:
      
         - The final version of the surprise device removal fixups from Bart.
      
         - Don't hide EFI partitions under advanced partition types.  It's
           fairly wide spread these days.  This is especially dangerous for
           systems that have both msdos and efi partition tables, where you
           want to keep them in sync.
      
         - Cleanup of using -1 instead of the proper NUMA_NO_NODE
      
         - Export control of bdi flusher thread CPU mask and default to using
           the home node (if known) from Jeff.
      
         - Export unplug tracepoint for MD.
      
         - Core improvements from Shaohua.  Reinstate the recursive merge, as
           the original bug has been fixed.  Add plugging for discard and also
           fix a problem handling non pow-of-2 discard limits.
      
        There's a trivial merge in block/blk-exec.c due to a fix that went
        into 3.7-rc at a later point than -rc4 where this is based."
      
      * 'for-3.8/core' of git://git.kernel.dk/linux-block:
        block: export block_unplug tracepoint
        block: add plug for blkdev_issue_discard
        block: discard granularity might not be power of 2
        deadline: Allow 0ms deadline latency, increase the read speed
        partitions: enable EFI/GPT support by default
        bsg: Remove unused function bsg_goose_queue()
        block: Make blk_cleanup_queue() wait until request_fn finished
        block: Avoid scheduling delayed work on a dead queue
        block: Avoid that request_fn is invoked on a dead queue
        block: Let blk_drain_queue() caller obtain the queue lock
        block: Rename queue dead flag
        bdi: add a user-tunable cpu_list for the bdi flusher threads
        block: use NUMA_NO_NODE instead of -1
        block: recursive merge requests
        block CFQ: avoid moving request to different queue

      Linus Torvalds authored
      Pull DRM updates from Dave Airlie:
       "This is the one and only next pull for 3.8, we had a regression we
        found last week, so I was waiting for that to resolve itself, and I
        ended up with some Intel fixes on top as well.
      
        Highlights:
         - new driver: nvidia tegra 20/30/hdmi support
         - radeon: add support for previously unused DMA engines, more HDMI
           regs, eviction speeds ups and fixes
         - i915: HSW support enable, agp removal on GEN6, seqno wrapping
         - exynos: IPP subsystem support (image post proc), HDMI
         - nouveau: display class reworking, nv20->40 z compression
         - ttm: start of locking fixes, rcu usage for lookups,
         - core: documentation updates, docbook integration, monotonic clock
           usage, move from connector to object properties"

      sched: numa: Fix build error if CONFIG_NUMA_BALANCING && !CONFIG_TRANSPARENT_HUGEPAGE · 221392c3
      Mel Gorman authored
      Michal Hocko reported that the following build error occurs if
      CONFIG_NUMA_BALANCING is set without THP support
      
        kernel/sched/fair.c: In function ‘task_numa_work’:
        kernel/sched/fair.c:932:55: error: call to ‘__build_bug_failed’ declared with attribute error: BUILD_BUG failed
      
      The problem is that HPAGE_PMD_SHIFT triggers a BUILD_BUG() on
      !CONFIG_TRANSPARENT_HUGEPAGE. This patch addresses the problem.
