       "Here are two USB bugfixes for your 3.6-rc7 tree.
      
        The OHCI fix has been reported a number of times and is a regression
        from 3.5, and the patch that causes the regression was on the way to
        the -stable trees before I was reminded (again) that this fix needed
        to get to your tree soon.
      
        The host controller bugfix was reported in older kernels as being
        pretty easy to trigger, and has been tested by Red Hat and their
        customers.
      
        Both have been in the usb-next branch in the -next tree for a while
        now, I just cherry-picked them out to get to you in time for the 3.6
        release.

      net: use bigger pages in __netdev_alloc_frag · 69b08f62
      Eric Dumazet authored
      We currently use percpu order-0 pages in __netdev_alloc_frag
      to deliver fragments used by __netdev_alloc_skb()
      
      Depending on NIC driver and arch being 32 or 64 bit, it allows a page to
      be split in several fragments (between 1 and 8), assuming PAGE_SIZE=4096
      
      Switching to bigger pages (32768 bytes for PAGE_SIZE=4096 case) allows :
      
      - Better filling of space (the ending hole overhead is less an issue)
      
      - Less calls to page allocator or accesses to page->_count
      
      - Could allow struct skb_shared_info futures changes without major
        performance impact.
      
      This patch implements a transparent fallback to smaller
      pages in case of memory pressure.
      
      It also uses a standard "struct page_frag" instead of a custom one.

      inetpeer: fix token initialization · bc9259a8
      Nicolas Dichtel authored
      When jiffies wraps around (for example, 5 minutes after the boot, see
      INITIAL_JIFFIES) and peer has just been created, now - peer->rate_last can be
      < XRLIM_BURST_FACTOR * timeout, so token is not set to the maximum value, thus
      some icmp packets can be unexpectedly dropped.
      
      Fix this case by initializing last_rate to 60 seconds in the past.

      qlcnic: Fix scheduling while atomic bug · 68b3f28c
      Narendra K authored
      In the device close path, 'qlcnic_fw_destroy_ctx' and
      'qlcnic_poll_rsp' call msleep. But  'qlcnic_fw_destroy_ctx' and
      'qlcnic_poll_rsp' are called with 'adapter->tx_clean_lock' spin lock
      held resulting in scheduling while atomic bug causing the following
      trace.
      
      I observed that the commit 012dc19a
      from John Fastabend addresses a similar issue in ixgbevf driver.
      Adopting the same approach used in the commit, this patch uses mdelay
      to address the issue.
