Pull DEFINE_PCI_DEVICE_TABLE removal from Bjorn Helgaas:
"Part two of the PCI changes for v3.17:
- Remove DEFINE_PCI_DEVICE_TABLE macro use (Benoit Taine)
It's a mechanical change that removes uses of the
DEFINE_PCI_DEVICE_TABLE macro. I waited until later in the merge
window to reduce conflicts, but it's possible you'll still see a few"

====================
pull request: wireless 2014-08-14
Please pull this batch of fixes intended for the 3.17 stream...
Arend van Spriel brings two brcmfmac fixes, one which fixes a memory
leak and one which corrects some merge damage.
Emmanuel Grumbach fixes Linus's iwlwifi firmware-related log spam.
Rickard Strandqvist does some proper NULL termination after a call
to strncpy.
Ronald Wahl corrects a carl9170 problem with sending URBs with the
wrong endpoint type (resulting in log spam).

xgene_enet_get_ring_size() returns a negative value in case of an error,
but its only caller in xgene_enet_create_desc_ring() currently uses the
return value directly as u32. Instead, check for a negative value first and
error out in case. Also move the call to xgene_enet_get_ring_size() before
devm_kzalloc() so we don't need to free anything in the error path.
This fixes the following issue reported by the Coverity Scanner:
** CID 1231336: Improper use of negative value (NEGATIVE_RETURNS)

There is no need to init .owner field.
Based on the patch from Peter Griffin <peter.griffin@linaro.org>
"mmc: remove .owner field for drivers using module_platform_driver"
This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."

Pull device tree updates from Grant Likely:
"The branch contains the following device tree changes the v3.17 merge
window:
Group changes to the device tree. In preparation for adding device
tree overlay support, OF_DYNAMIC is reworked so that a set of device
tree changes can be prepared and applied to the tree all at once.
OF_RECONFIG notifiers see the most significant change here so that
users always get a consistent view of the tree. Notifiers generation
is moved from before a change to after it, and notifiers for a group
of changes are emitted after the entire block of changes have been
applied
Automatic console selection from DT. Console drivers can now use
of_console_check() to see if the device node is specified as a console
device. If so then it gets added as a preferred console. UART
devices get this support automatically when uart_add_one_port() is
called.
DT unit tests no longer depend on pre-loaded data in the device tree.
Data is loaded dynamically at the start of unit tests, and then
unloaded again when the tests have completed.

Pull block driver changes from Jens Axboe:
"Nothing out of the ordinary here, this pull request contains:
- A big round of fixes for bcache from Kent Overstreet, Slava Pestov,
and Surbhi Palande. No new features, just a lot of fixes.
- The usual round of drbd updates from Andreas Gruenbacher, Lars
Ellenberg, and Philipp Reisner.
- virtio_blk was converted to blk-mq back in 3.13, but now Ming Lei
has taken it one step further and added support for actually using
more than one queue.
- Addition of an explicit SG_FLAG_Q_AT_HEAD for block/bsg, to
compliment the the default behavior of adding to the tail of the
queue. From Douglas Gilbert"

====================
Intel Wired LAN Driver Updates 2014-08-12
This series contains updates to i40e and e1000e.
Lucas provides a fix for i40e to resolve a compile issue where a header
was missing in the #includes.
Wei Yongjun provides a fix for i40e to resolve a sparse warning, where
a non-static function should be static.
Julia Lawall provides a fix for i40e which was found using Coccinelle,
where there was a typo in the name of the type given to sizeof().
Rickard Strandqvist provides a fix for i40e to replace the use of
strncpy() with strlcpy() to avoid strings that lack null termination.
Jean Sacren provides two e1000e fixes, first is a comment fix and second
removes an excessive space character in a debug message.

need to use loop anymore.

Reference count the number of packets in host stack, so that we don't
stop the deallocation thread too early. If not, we can end up with
xenvif_free permanently waiting for deallocation thread to unmap grefs.

Originally netif_napi_add was in xenvif_init_queue and netif_napi_del
was in xenvif_deinit_queue, while kthreads were handled in
xenvif_connect and xenvif_disconnect. Move netif_napi_add and
netif_napi_del to xenvif_connect and xenvif_disconnect so that they

When tp->hw_stats is 0, tg3_get_stats64 should display previously

ldc_rx -> vnet_rx -> .. -> vnet_walk_rx->vnet_send_ack should not
spin into an infinite loop waiting EAGAIN to lift.
The sender could have sent us a burst, and gone to lunch without
doing any more ldc_read()'s. That should not cause the receiver to
loop infinitely till soft-lockup kicks in.
Similarly __vnet_tx_trigger should only loop on EAGAIN a finite
number of times. The caller (vnet_start_xmit()) already has code
to reset the dring state and bail on errors from __vnet_tx_trigger

Pull x86/apic updates from Thomas Gleixner:
"This is a major overhaul to the x86 apic subsystem consisting of the
following parts:
- Remove obsolete APIC driver abstractions (David Rientjes)
- Use the irqdomain facilities to dynamically allocate IRQs for
IOAPICs. This is a prerequisite to enable IOAPIC hotplug support,
and it also frees up wasted vectors (Jiang Liu)
- Misc fixlets.
Despite the hickup in Ingos previous pull request - caused by the
missing fixup for the suspend/resume issue reported by Borislav - I
strongly recommend that this update finds its way into 3.17. Some
history for you:
This is preparatory work for physical IOAPIC hotplug. The first
attempt to support this was done by Yinghai and I shot it down because
it just added another layer of obscurity and complexity to the already
existing mess without tackling the underlying shortcomings of the
current implementation.
After quite some on- and offlist discussions, I requested that the
design of this functionality must use generic infrastructure, i.e.
irq domains, which provide all the mechanisms to dynamically map linux
interrupt numbers to physical interrupts.
Jiang picked up the idea and did a great job of consolidating the
existing interfaces to manage the x86 (IOAPIC) interrupt system by
utilizing irq domains.
The testing in tip, Linux-next and inside of Intel on various machines
did not unearth any oddities until Borislav exposed it to one of his
oddball machines. The issue was resolved quickly, but unfortunately
the fix fell through the cracks and did not hit the tip tree before
Ingo sent the pull request. Not entirely Ingos fault, I also assumed
that the fix was already merged when Ingo asked me whether he could
send it.
Nevertheless this work has a proper design, has undergone several
rounds of review and the final fallout after applying it to tip and
integrating it into Linux-next has been more than moderate. It's the
ground work not only for IOAPIC hotplug, it will also allow us to move
the lowlevel vector allocation into the irqdomain hierarchy, which
will benefit other architectures as well. Patches are posted already,
but they are on hold for two weeks, see below.
I really appreciate the competence and responsiveness Jiang has shown
in course of this endavour. So I'm sure that any fallout of this will
be addressed in a timely manner.
FYI, I'm vanishing for 2 weeks into my annual kids summer camp kitchen
duty^Wvacation, while you folks are drooling at KS/LinuxCon :) But HPA
will have a look at the hopefully zero fallout until I'm back"
