      Only compile time tested, noticed nv50_fence_create was never used,
      so fix this. This will probably fix vblank on nv50 cards.
      
      Hopefully this is still in time for 3.7 final release.

      fix incorrect NR_FREE_PAGES accounting (appears like memory leak) · ef6c5be6
      Dave Hansen 提交于
      There have been some 3.7-rc reports of vm issues, including some kswapd
      bugs and, more importantly, some memory "leaks":
      
      	http://www.spinics.net/lists/linux-mm/msg46187.html
      	https://bugzilla.kernel.org/show_bug.cgi?id=50181
      
      Commit 1fb3f8ca ("mm: compaction: capture a suitable high-order page
      immediately when it is made available") took split_free_page() and
      reused it for the compaction code.  It does something curious with
      capture_free_page() (previously known as split_free_page()):
      
        int capture_free_page(struct page *page, int alloc_order,
        ...
                __mod_zone_page_state(zone, NR_FREE_PAGES, -(1UL << order));
      
        -       /* Split into individual pages */
        -       set_page_refcounted(page);
        -       split_page(page, order);
        +       if (alloc_order != order)
        +               expand(zone, page, alloc_order, order,
        +                       &zone->free_area[order], migratetype);
      
      Note that expand() puts the pages _back_ in the allocator, but it does
      not bump NR_FREE_PAGES.  We "return" 'alloc_order' worth of pages, but
      we accounted for removing 'order' in the __mod_zone_page_state() call.
      
      For the old split_page()-style use (order==alloc_order) the bug will not
      trigger.  But, when called from the compaction code where we
      occasionally get a larger page out of the buddy allocator than we need,
      we will run in to this.
      
      This patch simply changes the NR_FREE_PAGES manipulation to the correct
      'alloc_order' instead of 'order'.
      
      I've been able to repeatedly trigger this in my testing environment.
      The amount "leaked" very closely tracks the imbalance I see in buddy
      pages vs.  NR_FREE_PAGES.  I have confirmed that this patch fixes the
      imbalance

      ARM - OMAP: ads7846: fix pendown debounce setting · 0a0d6285
      Igor Grinberg 提交于
      Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
      pendown GPIO debounce time setting by the below sequence:
      
        gpio_request_one()
        gpio_set_debounce()
        gpio_free()
      
      It also revealed a bug in the OMAP GPIO handling code which prevented
      the GPIO debounce clock to be disabled and CORE transition to low power
      states.
      
      Commit c9c55d92 (gpio/omap: fix off-mode bug: clear debounce settings on
      free/reset) fixes the OMAP GPIO handling code by making sure that the
      GPIO debounce clock gets disabled if no GPIO is requested from current
      bank.
      
      While fixing the OMAP GPIO handling code (in the right way), the above
      commit makes the gpio_request->set_debounce->free sequence invalid as
      after freeing the GPIO, the debounce settings are lost.
      
      Fix the debounce settings by moving the debounce initialization to the
      actual GPIO requesting code - the ads7846 driver.

      Igor Grinberg 提交于
      Some platforms need the pendown GPIO debounce time setting programmed.
      Since the pendown GPIO is handled by the driver, the debounce time
      should also be handled along with the pendown GPIO request.
