Alexey Khoroshilov 9494849e53 ath9k_htc: fix data race between request_firmware_nowait() callback and suspend()
ath9k_hif_usb_probe() requests firmware asynchronically and
there is some initialization postponed till firmware is ready.
In particular, ath9k_hif_usb_firmware_cb() callback initializes
hif_dev->tx.tx_buf and hif_dev->tx.tx_pending lists.

At the same time, ath9k_hif_usb_suspend() iterates that lists through
ath9k_hif_usb_dealloc_urbs(). If suspend happens before request_firmware_nowait()
callback is called, it can lead to oops.

Similar issue could be in ath9k_hif_usb_disconnect(), but it is prevented
using hif_dev->fw_done completion and HIF_USB_READY flag. The patch extends
this approach to suspend() as well.

Found by Linux Driver Verification project (linuxtesting.org).

Larry Finger bcfb879432 rtlwifi: Initialize power-setting callback for USB devices
Commit a269913c5 entitled "rtlwifi: Rework rtl_lps_leave() and
rtl_lps_enter() to use work queue" has two bugs for USB drivers.
Firstly, the work queue in question was not initialized. Secondly,
the callback routine used by this queue is contained within the
file used for PCI devices. As a result, it is not available for
architectures without PCI hardware.

Linus Torvalds 54be820019 Merge branch 'slab/for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/linux
Pull slab update from Pekka Enberg:
 "Highlights:

  - Fix for boot-time problems on some architectures due to
    init_lock_keys() not respecting kmalloc_caches boundaries
    (Christoph Lameter)

  - CONFIG_SLUB_CPU_PARTIAL requested by RT folks (Joonsoo Kim)

  - Fix for excessive slab freelist draining (Wanpeng Li)

  - SLUB and SLOB cleanups and fixes (various people)"

I ended up editing the branch, and this avoids two commits at the end
that were immediately reverted, and I instead just applied the oneliner
fix in between myself.

Now, this uses SLUB pretty much unmodified, but as it is the -rt kernel
with CONFIG_PREEMPT_RT set, spinlocks are mutexes, although they do
disable migration. But the SLUB code is relatively lockless, and the
spin_locks there are raw_spin_locks (not converted to mutexes), thus I
believe this bug can happen in mainline without -rt features. The -rt
patch is just good at triggering mainline bugs ;-)

Anyway, looking at where this crashed, it seems that the page variable
can be NULL when passed to the node_match() function (which does not
check if it is NULL). When this happens we get the above panic.

As page is only used in slab_alloc() to check if the node matches, if
it's NULL I'm assuming that we can say it doesn't and call the
__slab_alloc() code. Is this a correct assumption?

Linus Torvalds 9663398a09 ARM: SoC fixes for 3.11-rc
This is our first set of fixes from arm-soc for 3.11.
  - A handful of build and warning fixes from Arnd
  - A collection of OMAP fixes
  - defconfig updates to make the default configs more useful for real use
    (and testing) out of the box on hardware.
 
 And a couple of other small fixes. Some of these have been recently
 applied but it's normally how we deal with fixes, with less bake time
 in -next needed.

Oleg Nesterov e9a17bd73a llist: llist_add() can use llist_add_batch()
llist_add(new, head) can simply use llist_add_batch(new, new, head),
no need to duplicate the code.

This obviously uninlines llist_add() and to me this is a win. But we
can make llist_add_batch() inline if this is desirable, in this case
gcc can notice that new_first == new_last if the caller is llist_add().

Oleg Nesterov fb4214db50 llist: fix/simplify llist_add() and llist_add_batch()
1. This is mostly theoretical, but llist_add*() need ACCESS_ONCE().

   Otherwise it is not guaranteed that the first cmpxchg() uses the
   same value for old_entry and new_last->next.

2. These helpers cache the result of cmpxchg() and read the initial
   value of head->first before the main loop. I do not think this
   makes sense. In the likely case cmpxchg() succeeds, otherwise
   it doesn't hurt to reload head->first.

   I think it would be better to simplify the code and simply read
   ->first before cmpxchg().

This is unlikely path, it is not that this change can improve

Hannes Frederic Sowa 307f2fb95e ipv6: only static routes qualify for equal cost multipathing
Static routes in this case are non-expiring routes which did not get
configured by autoconf or by icmpv6 redirects.

To make sure we actually get an ecmp route while searching for the first
one in this fib6_node's leafs, also make sure it matches the ecmp route
assumptions.

v2:
a) Removed RTF_EXPIRE check in dst.from chain. The check of RTF_ADDRCONF
   already ensures that this route, even if added again without
   RTF_EXPIRES (in case of a RA announcement with infinite timeout),
   does not cause the rt6i_nsiblings logic to go wrong if a later RA
   updates the expiration time later.

v3:
a) Allow RTF_EXPIRES routes to enter the ecmp route set. We have to do so,
   because an pmtu event could update the RTF_EXPIRES flag and we would
   not count this route, if another route joins this set. We now filter
   only for RTF_GATEWAY|RTF_ADDRCONF|RTF_DYNAMIC, which are flags that
   don't get changed after rt6_info construction.

The usual straighforward failure to check for dma_mapping_error after a map
operation is completed.

This patch should fix it, the reporter wandered off after filing this bz:
https://bugzilla.redhat.com/show_bug.cgi?id=954170

and I don't have hardware to test, but the fix is pretty straightforward, so I
figured I'd post it for review.
