 "A few fixes for problems discovered during the 3.6 cycle.

  Of particular note, are fixes to the thin target's discard support,
  which I hope is finally working correctly; and fixes for multipath
  ioctls and device limits when there are no paths."

Andrea Arcangeli 99a1300e1d thp: avoid VM_BUG_ON page_count(page) false positives in __collapse_huge_page_copy
Speculative cache pagecache lookups can elevate the refcount from
under us, so avoid the false positive. If the refcount is < 2 we'll be
notified by a VM_BUG_ON in put_page_testzero as there are two
put_page(src_page) in a row before returning from this function.

  The host controller bugfix was reported in older kernels as being
  pretty easy to trigger, and has been tested by Red Hat and their

  now, I just cherry-picked them out to get to you in time for the 3.6

Eric Dumazet 69b08f62e1 net: use bigger pages in __netdev_alloc_frag
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.

Nicolas Dichtel bc9259a8ba inetpeer: fix token initialization
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.

Narendra K 68b3f28c11 qlcnic: Fix scheduling while atomic bug
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 012dc19a45
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.
