      fix incorrect NR_FREE_PAGES accounting (appears like memory leak) · ef6c5be6
      Dave Hansen authored
      There have been some 3.7-rc reports of vm issues, including some kswapd
      bugs and, more importantly, some memory "leaks":
      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

      ARM - OMAP: ads7846: fix pendown debounce setting · 0a0d6285
      Igor Grinberg authored
      Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
      pendown GPIO debounce time setting by the below sequence:
      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
      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
      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.

      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.

      The thing is that team_dev_queue_xmit() returns NET_XMIT_* or -E*.
      bc_trasmit() should return true in case all went well. So use ! to get
      correct retval from team_dev_queue_xmit() result.

      xen/netfront: handle compound page fragments on transmit · f36c3747
      Ian Campbell authored
      An SKB paged fragment can consist of a compound page with order > 0.
      However the netchannel protocol deals only in PAGE_SIZE frames.
      Handle this in xennet_make_frags by iterating over the frames which
      make up the page.
      This is the netfront equivalent to 6a8ed462 for netback.

      John W. Linville says:
      This is a batch of fixes intended for 3.7...
      Included are two pulls.  Regarding the mac80211 tree, Johannes says:
      "Please pull my mac80211.git tree (see below) to get two more fixes for
      3.7. Both fix regressions introduced *before* this cycle that weren't
      noticed until now, one for IBSS not cleaning up properly and the other
      to add back the "wireless" sysfs directory for Fedora's startup scripts."
      Regarding the iwlwifi tree, Johannes says:
      "Please also pull my iwlwifi.git tree, I have two fixes: one to remove a
      spurious warning that can actually trigger in legitimate situations, and
      the other to fix a regression from when monitor mode was changed to use
      the "sniffer" firmware mode."
      Also included is an nfc tree pull.  Samuel says:
      "We mostly have pn533 fixes here, 2 memory leaks and an early unlocking fix.
      Moreover, we also have an LLCP adapter linked list insertion fix."
      On top of that, a few more bits...  Albert Pool adds a USB ID
      to rtlwifi.  Bing Zhao provides two mwifiex fixes -- one to fix
      a system hang during a command timeout, and the other to properly
      report a suspend error to the MMC core.  Finally, Sujith Manoharan
      fixes a thinko that would trigger an ath9k hang during device reset.
