Linus Torvalds f98982ce80 Merge branch 'x86-platform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 platform changes from Ingo Molnar:

 - Support for the Technologic Systems TS-5500 platform, by Vivien
   Didelot

 - Improved NUMA support on AMD systems:

   Add support for federated systems where multiple memory controllers
   can exist and see each other over multiple PCI domains.  This
   basically means that AMD node ids can be more than 8 now and the code
   handling this is taught to incorporate PCI domain into those IDs.

 - Support for the Goldfish virtual Android emulator, by Jun Nakajima,
   Intel, Google, et al.

 - Misc fixlets.

David S. Miller c6b5380797 Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:

====================
One last batch of stragglers intended for 3.9...

For the iwlwifi pull, Johannes says:

"I hadn't expected to ask you to pull iwlwifi-next again, but I have a
number of fixes most of which I'd also send in after rc1, so here it is.

The first commit is a merge error between mac80211-next and
iwlwifi-next; in addition I have fixes for P2P scanning and MVM driver
MAC (virtual interface) management from Ilan, a CT-kill (critical
temperature) fix from Eytan, and myself fixed three different little but
annoying bugs in the MVM driver.

The only ones I might not send for -rc1 are Emmanuel's debug patch, but
OTOH it should help greatly if there are any issues, and my own time
event debugging patch that I used to find the race condition but we
decided to keep it for the future."

For the mac80211 pull, Johannes says:

"Like iwlwifi-next, this would almost be suitable for rc1.

I have a fix for station management on non-TDLS drivers, a CAB queue
crash fix for mesh, a fix for an annoying (but harmless) warning, a
tracing fix and a documentation fix. Other than that, only a few mesh
cleanups."

Along with that is a fix for memory corruption in rtlwifi, an
orinoco_usb fix to avoid allocating a DMA buffer on the stack, an a
hostap fix to return -ENOMEM instead of -1 after a memory allocation
failure.  The remaining bits implement 802.11ac support for the mwifiex
driver -- I think that is still worth getting into 3.9.

Please let me know if there are problems!

Pull two x86 kernel build changes from Ingo Molnar:
 "The first change modifies how 'make oldconfig' works on cross-bitness

Pull x86/apic changes from Ingo Molnar:
 "Main changes:

   - Multiple MSI support added to the APIC, PCI and AHCI code - acked
     by all relevant maintainers, by Alexander Gordeev.

     The advantage is that multiple AHCI ports can have multiple MSI
     irqs assigned, and can thus spread to multiple CPUs.

     [ Drivers can make use of this new facility via the
       pci_enable_msi_block_auto() method ]

   - x86 IOAPIC code from interrupt remapping cleanups from Joerg
     Roedel:

     These patches move all interrupt remapping specific checks out of
     the x86 core code and replaces the respective call-sites with
     function pointers.  As a result the interrupt remapping code is
     better abstraced from x86 core interrupt handling code.

   - Various smaller improvements, fixes and cleanups."

Linus Torvalds 8f55cea410 Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf changes from Ingo Molnar:
 "There are lots of improvements, the biggest changes are:

  Main kernel side changes:

   - Improve uprobes performance by adding 'pre-filtering' support, by
     Oleg Nesterov.

   - Make some POWER7 events available in sysfs, equivalent to what was
     done on x86, from Sukadev Bhattiprolu.

   - tracing updates by Steve Rostedt - mostly misc fixes and smaller
     improvements.

   - Use perf/event tracing to report PCI Express advanced errors, by
     Tony Luck.

   - Enable northbridge performance counters on AMD family 15h, by Jacob
     Shin.

   - This tracing commit:

        tracing: Remove the extra 4 bytes of padding in events

     changes the ABI.  All involved parties (PowerTop in particular)
     seem to agree that it's safe to do now with the introduction of
     libtraceevent, but the devil is in the details ...

  Main tooling side changes:

   - Add 'event group view', from Namyung Kim:

     To use it, 'perf record' should group events when recording.  And
     then perf report parses the saved group relation from file header
     and prints them together if --group option is provided.  You can
     use the 'perf evlist' command to see event group information:

        $ perf record -e '{ref-cycles,cycles}' noploop 1
        [ perf record: Woken up 2 times to write data ]
        [ perf record: Captured and wrote 0.385 MB perf.data (~16807 samples) ]

        $ perf evlist --group
        {ref-cycles,cycles}

     With this example, default perf report will show you each event
     separately.

     You can use --group option to enable event group view:

        $ perf report --group
        ...
        # group: {ref-cycles,cycles}
        # ========
        # Samples: 7K of event 'anon group { ref-cycles, cycles }'
        # Event count (approx.): 6876107743
        #
        #         Overhead  Command      Shared Object                      Symbol
        # ................  .......  .................  ..........................

             0.00%   0.02%  noploop  [kernel.kallsyms]  [k] __current_kernel_time

     As you can see the Overhead column now contains both of ref-cycles
     and cycles and header line shows group information also - 'anon
     group { ref-cycles, cycles }'.  The output is sorted by period of
     group leader first.

   - Initial GTK+ annotate browser, from Namhyung Kim.

   - Add option for runtime switching perf data file in perf report,
     just press 's' and a menu with the valid files found in the current
     directory will be presented, from Feng Tang.

   - Add support to display whole group data for raw columns, from Jiri
     Olsa.

   - Add per processor socket count aggregation in perf stat, from
     Stephane Eranian.

   - Add interval printing in 'perf stat', from Stephane Eranian.

   - 'perf test' improvements

   - Add support for wildcards in tracepoint system name, from Jiri
     Olsa.

   - Add anonymous huge page recognition, from Joshua Zhu.

   - perf build-id cache now can show DSOs present in a perf.data file
     that are not in the cache, to integrate with build-id servers being
     put in place by organizations such as Fedora.

   - perf top now shares more of the evsel config/creation routines with
     'record', paving the way for further integration like 'top'
     snapshots, etc.

   - perf top now supports DWARF callchains.

   - Fix mmap limitations on 32-bit, fix from David Miller.

   - 'perf bench numa mem' NUMA performance measurement suite

   - ... and lots of fixes, performance improvements, cleanups and other
     improvements I failed to list - see the shortlog and git log for
     details."

Eric Dumazet 303c07db48 ppp: set qdisc_tx_busylock to avoid LOCKDEP splat
If a qdisc is installed on a ppp device, its possible to get
a lockdep splat under stress, because nested dev_queue_xmit() can
lock busylock a second time (on a different device, so its a false
positive)

Avoid this problem using a distinct lock_class_key for ppp
devices.

Gao feng 4fc1a601f1 net: proc: fix build failed when procfs is not configured
commit d4beaa66ad
"net: proc: change proc_net_fops_create to proc_create"
uses proc_create to replace proc_net_fops_create, when
CONFIG_PROC isn't configured, some build error will
occurs.

net/packet/af_packet.c: In function 'packet_net_init':
net/packet/af_packet.c:3831:48: error: 'packet_seq_fops' undeclared (first use in this function)
net/packet/af_packet.c:3831:48: note: each undeclared identifier is reported only once for each function it appears in

There may be other build fails like above,this patch
change proc_create from function to macros when CONFIG_PROC
is not configured,just like what proc_net_fops_create did
before this commit.

delayed_work_timer_fn() only for GPL modules. This makes delayed-works
unusable for non-GPL modules, because initialization macro now requires
GPL symbol. For example schedule_delayed_work() available for non-GPL.

David S. Miller 629821d9b0 Revert "xen: netback: remove redundant xenvif_put"
This reverts commit d37204566a.

This change is incorrect, as per Jan Beulich:

====================
But this is wrong from all we can tell, we discussed this before
(Wei pointed to the discussion in an earlier reply). The core of
it is that the put here parallels the one in netbk_tx_err(), and
the one in xenvif_carrier_off() matches the get from
xenvif_connect() (which normally would be done on the path
coming through xenvif_disconnect()).
====================

David Henningsson 4bd038f9d8 ALSA: hda - hdmi: Protect ELD buffer
Because the eld buffer can be simultaneously accessed from both
workqueue context (updating) and process context (kcontrol read),
we need to protect it with a mutex to guarantee consistency.

To avoid holding the mutex while reading the ELD info from the
codec, we introduce a temporary eld buffer.

Trond Myklebust 666b3d803a NLM: Ensure that we resend all pending blocking locks after a reclaim
Currently, nlmclnt_lock will break out of the for(;;) loop when
the reclaimer wakes up the blocking lock thread by setting
nlm_lck_denied_grace_period. This causes the lock request to fail
with an ENOLCK error.
The intention was always to ensure that we resend the lock request
after the grace period has expired.
