From Stephen Warren:
ARM: tegra: core SoC code enhancements

Various small clock initialization table and driver changes to support
WiFi modules, SPI controllers, and host1x (graphics/display hardware).

Various AHB/APB-related clocks were added to the Tegra30 clock driver.

The level 2 cache initialization is now driven by data from device tree,
and the cache configuration tweaked.

AUXDATA is added to support SPI controllers and host1x.

Code to decode Tegra's "speedo" process identification fuses is added.

This pull request is based on tegra-for-3.8-cleanup.

Pull networking fixes from David Miller:
 "Bug fixes galore, mostly in drivers as is often the case:

  1) USB gadget and cdc_eem drivers need adjustments to their frame size
     lengths in order to handle VLANs correctly.  From Ian Coolidge.

  2) TIPC and several network drivers erroneously call tasklet_disable
     before tasklet_kill, fix from Xiaotian Feng.

  3) r8169 driver needs to apply the WOL suspend quirk to more chipsets,
     fix from Cyril Brulebois.

  4) Fix multicast filters on RTL_GIGA_MAC_VER_35 r8169 chips, from
     Nathan Walp.

  5) FDB netlink dumps should use RTM_NEWNEIGH as the message type, not
     zero.  From John Fastabend.

  6) Fix smsc95xx tx checksum offload on big-endian, from Steve
     Glendinning.

  7) __inet_diag_dump() needs to repsect and report the error value
     returned from inet_diag_lock_handler() rather than ignore it.
     Otherwise if an inet diag handler is not available for a particular
     protocol, we essentially report success instead of giving an error
     indication.  Fix from Cyrill Gorcunov.

  8) When the QFQ packet scheduler sees TSO/GSO packets it does not
     handle things properly, and in fact ends up corrupting it's
     datastructures as well as mis-schedule packets.  Fix from Paolo
     Valente.

  9) Fix oopser in skb_loop_sk(), from Eric Leblond.

  10) CXGB4 passes partially uninitialized datastructures in to FW
      commands, fix from Vipul Pandya.

  11) When we send unsolicited ipv6 neighbour advertisements, we should
      send them to the link-local allnodes multicast address, as per
      RFC4861.  Fix from Hannes Frederic Sowa.

  12) There is some kind of bug in the usbnet's kevent deferral
      mechanism, but more immediately when it triggers an uncontrolled
      stream of kernel messages spam the log.  Rate limit the error log
      message triggered when this problem occurs, as sending thousands
      of error messages into the kernel log doesn't help matters at all,
      and in fact makes further diagnosis more difficult.

      From Steve Glendinning.

  13) Fix gianfar restore from hibernation, from Wang Dongsheng.

  14) The netlink message attribute sizes are wrong in the ipv6 GRE
      driver, it was using the size of ipv4 addresses instead of ipv6
      ones :-) Fix from Nicolas Dichtel."

  1) Configuring a mix of static vs.  modular sparc64 crypto modules
     didn't work, remove an ill-conceived attempt to only have to build
     the device match table for these drivers once to fix the problem.

     Reported by Meelis Roos.

  2) Make the montgomery multiple/square and mpmul instructions actually
     usable in 32-bit tasks.  Essentially this involves providing 32-bit
     userspace with a way to use a 64-bit stack when it needs to.

  3) Our sparc64 atomic backoffs don't yield cpu strands properly on
     Niagara chips.  Use pause instruction when available to achieve
     this, otherwise use a benign instruction we know blocks the strand
     for some time.

  4) Wire up kcmp

  5) Fix the build of various drivers by removing the unnecessary
     blocking of OF_GPIO when SPARC.

0bce04be44 of/address: sparc: Declare of_address_to_resource() as an extern function for sparc again
This bug-fix makes sure that of_address_to_resource is defined extern for sparc
so that the sparc-specific implementation of of_address_to_resource() is once
again used when including include/linux/of_address.h in a sparc context. A
number of drivers in mainline relies on this function working for sparc.

The bug was introduced in a850a75544, "of/address:
add empty static inlines for !CONFIG_OF". Contrary to that commit title, the
static inlines are added for !CONFIG_OF_ADDRESS, and CONFIG_OF_ADDRESS is never
defined for sparc. This is good behavior for the other functions in
include/linux/of_address.h, as the extern functions defined in
drivers/of/address.c only gets linked when OF_ADDRESS is configured. However,
for of_address_to_resource there exists a sparc-specific implementation in
arch/sparc/arch/sparc/kernel/of_device_common.c

a80a6b85b4 revert "epoll: support for disabling items, and a self-test app"
Revert commit 03a7beb55b ("epoll: support for disabling items, and a
self-test app") pending resolution of the issues identified by Michael
Kerrisk, copied below.

We'll revisit this for 3.8.

: I've taken a look at this patch as it currently stands in 3.7-rc1, and
: done a bit of testing. (By the way, the test program
: tools/testing/selftests/epoll/test_epoll.c does not compile...)
:
: There are one or two places where the behavior seems a little strange,
: so I have a question or two at the end of this mail. But other than
: that, I want to check my understanding so that the interface can be
: correctly documented.
:
: Just to go though my understanding, the problem is the following
: scenario in a multithreaded application:
:
: 1. Multiple threads are performing epoll_wait() operations,
:    and maintaining a user-space cache that contains information
:    corresponding to each file descriptor being monitored by
:    epoll_wait().
:
: 2. At some point, a thread wants to delete (EPOLL_CTL_DEL)
:    a file descriptor from the epoll interest list, and
:    delete the corresponding record from the user-space cache.
:
: 3. The problem with (2) is that some other thread may have
:    previously done an epoll_wait() that retrieved information
:    about the fd in question, and may be in the middle of using
:    information in the cache that relates to that fd. Thus,
:    there is a potential race.
:
: 4. The race can't solved purely in user space, because doing
:    so would require applying a mutex across the epoll_wait()
:    call, which would of course blow thread concurrency.
:
: Right?
:
: Your solution is the EPOLL_CTL_DISABLE operation. I want to
: confirm my understanding about how to use this flag, since
: the description that has accompanied the patches so far
: has been a bit sparse
:
: 0. In the scenario you're concerned about, deleting a file
:    descriptor means (safely) doing the following:
:    (a) Deleting the file descriptor from the epoll interest list
:        using EPOLL_CTL_DEL
:    (b) Deleting the corresponding record in the user-space cache
:
: 1. It's only meaningful to use this EPOLL_CTL_DISABLE in
:    conjunction with EPOLLONESHOT.
:
: 2. Using EPOLL_CTL_DISABLE without using EPOLLONESHOT in
:    conjunction is a logical error.
:
: 3. The correct way to code multithreaded applications using
:    EPOLL_CTL_DISABLE and EPOLLONESHOT is as follows:
:
:    a. All EPOLL_CTL_ADD and EPOLL_CTL_MOD operations should
:       should EPOLLONESHOT.
:
:    b. When a thread wants to delete a file descriptor, it
:       should do the following:
:
:       [1] Call epoll_ctl(EPOLL_CTL_DISABLE)
:       [2] If the return status from epoll_ctl(EPOLL_CTL_DISABLE)
:           was zero, then the file descriptor can be safely
:           deleted by the thread that made this call.
:       [3] If the epoll_ctl(EPOLL_CTL_DISABLE) fails with EBUSY,
:           then the descriptor is in use. In this case, the calling
:           thread should set a flag in the user-space cache to
:           indicate that the thread that is using the descriptor
:           should perform the deletion operation.
:
: Is all of the above correct?
:
: The implementation depends on checking on whether
: (events & ~EP_PRIVATE_BITS) == 0
: This replies on the fact that EPOLL_CTL_AD and EPOLL_CTL_MOD always
: set EPOLLHUP and EPOLLERR in the 'events' mask, and EPOLLONESHOT
: causes those flags (as well as all others in ~EP_PRIVATE_BITS) to be
: cleared.
:
: A corollary to the previous paragraph is that using EPOLL_CTL_DISABLE
: is only useful in conjunction with EPOLLONESHOT. However, as things
: stand, one can use EPOLL_CTL_DISABLE on a file descriptor that does
: not have EPOLLONESHOT set in 'events' This results in the following
: (slightly surprising) behavior:
:
: (a) The first call to epoll_ctl(EPOLL_CTL_DISABLE) returns 0
:     (the indicator that the file descriptor can be safely deleted).
: (b) The next call to epoll_ctl(EPOLL_CTL_DISABLE) fails with EBUSY.
:
: This doesn't seem particularly useful, and in fact is probably an
: indication that the user made a logic error: they should only be using
: epoll_ctl(EPOLL_CTL_DISABLE) on a file descriptor for which
: EPOLLONESHOT was set in 'events'. If that is correct, then would it
: not make sense to return an error to user space for this case?

38669e045d ARM: vexpress: Start using new Versatile Express infrastructure
This patch starts using all the configuration infrastructure.

- generic GPIO library is forced now

- sysreg GPIOs are used as MMC CD and WP information sources;
  thanks to this MMCI auxiliary data is not longer necessary

- DVI muxer and mode control is removed from non-DT V2P-CA9 code
  as this is now handled by the vexpress-dvi driver

- clock generators control is removed as is being handled by the
  common clock driver now

- the sysreg and sysctl control is now delegated to the
  appropriate drivers and all related code was removed

- NOR Flash set_vpp function has been removed as the control
  bit used does _not_ control its VPP line, but the #WP signal
  instead (which is de facto unusable in case of Linux MTD
  drivers); this also allowed the remove its DT auxiliary
  data

The non-DT code defines only minimal required number of
the config devices. Device Trees are updated to make use
of all new features.

88e0abcd7a mfd: Versatile Express system registers driver
This is a platform driver for Versatile Express' "system
register" block. It's a random collection of registers providing
the following functionality:

- low level platform functions like board ID access; in order to
  use those, the driver must be initialized early, either statically
  or based on the DT

- config bus bridge via "system control" interface; as the response
  from the controller does not generate interrupt (yet), the status
  register is periodically polled using a timer

- pseudo GPIO lines providing MMC card status and Flash WP#
  signal control

- LED interface for a set of 8 LEDs on the motherboard, with
  "heartbeat", "mmc0" and "cpu0" to "cpu5" as default triggers

3ecbf05be1 mfd: Versatile Express config infrastructure
Versatile Express platform has an elaborated configuration system,
consisting of microcontrollers residing on the mother- and
daughterboards known as Motherboard/Daughterboard Configuration
Controller (MCC and DCC). The controllers are responsible for
the platform initialization (reset generation, flash programming,
FPGA bitfiles loading etc.) but also control clock generators,
voltage regulators, gather environmental data like temperature,
power consumption etc. Even the video output switch (FPGA) is
controlled that way.

Those devices are _not_ visible in the main address space and
the usual communication channel uses some kind of a bridge in
the peripheral block sending commands (requests) to the
controllers and receiving responses. It can take up to
500 microseconds for a transaction to be completed, therefore
it is important to provide a non-blocking interface to it.

This patch adds an abstraction of this infrastructure. Bridge
drivers can register themselves with the framework. Then,
a driver of a device can request an abstract "function" - the
request will be redirected to a bridge referred by thedd
"arm,vexpress,config-bridge" property of the device tree node.

87da7e66a4 KVM: x86: fix vcpu->mmio_fragments overflow
After commit b3356bf0db (KVM: emulator: optimize "rep ins" handling),
the pieces of io data can be collected and write them to the guest memory
or MMIO together

Unfortunately, kvm splits the mmio access into 8 bytes and store them to
vcpu->mmio_fragments. If the guest uses "rep ins" to move large data, it
will cause vcpu->mmio_fragments overflow

The bug can be exposed by isapc (-M isapc):

[23154.818733] general protection fault: 0000 [#1] SMP DEBUG_PAGEALLOC
[ ......]
[23154.858083] Call Trace:
[23154.859874]  [<ffffffffa04f0e17>] kvm_get_cr8+0x1d/0x28 [kvm]
[23154.861677]  [<ffffffffa04fa6d4>] kvm_arch_vcpu_ioctl_run+0xcda/0xe45 [kvm]
[23154.863604]  [<ffffffffa04f5a1a>] ? kvm_arch_vcpu_load+0x17b/0x180 [kvm]

Actually, we can use one mmio_fragment to store a large mmio access then
split it when we pass the mmio-exit-info to userspace. After that, we only
need two entries to store mmio info for the cross-mmio pages access

95a7d76897 xen/mmu: Use Xen specific TLB flush instead of the generic one.
As Mukesh explained it, the MMUEXT_TLB_FLUSH_ALL allows the
hypervisor to do a TLB flush on all active vCPUs. If instead
we were using the generic one (which ends up being xen_flush_tlb)
we end up making the MMUEXT_TLB_FLUSH_LOCAL hypercall. But
before we make that hypercall the kernel will IPI all of the
vCPUs (even those that were asleep from the hypervisor
perspective). The end result is that we needlessly wake them
up and do a TLB flush when we can just let the hypervisor
do it correctly.

This patch gives around 50% speed improvement when migrating
idle guest's from one host to another.

a0830dbd4e ALSA: Add a reference counter to card instance
For more strict protection for wild disconnections, a refcount is
introduced to the card instance, and let it up/down when an object is
referred via snd_lookup_*() in the open ops.

The free-after-last-close check is also changed to check this refcount
instead of the empty list, too.

2ac6b1f50a clk: Don't return negative numbers for unsigned values with !clk
Some of the helper functions return negative error codes if
passed a NULL clock. This can lead to confusing behavior when the
expected return value is unsigned. Fix up these accessors so that
they return unsigned values (or bool in the case of is_enabled).
This way we can't interpret NULL clocks as having valid and
interesting values.

1bf11c5353 percpu-rw-semaphores: use rcu_read_lock_sched
Use rcu_read_lock_sched / rcu_read_unlock_sched / synchronize_sched
instead of rcu_read_lock / rcu_read_unlock / synchronize_rcu.

This is an optimization. The RCU-protected region is very small, so
there will be no latency problems if we disable preempt in this region.

So we use rcu_read_lock_sched / rcu_read_unlock_sched that translates
to preempt_disable / preempt_disable. It is smaller (and supposedly
faster) than preemptible rcu_read_lock / rcu_read_unlock.

5c1eabe685 percpu-rw-semaphores: use light/heavy barriers
This patch introduces new barrier pair light_mb() and heavy_mb() for
percpu rw semaphores.

This patch fixes a bug in percpu-rw-semaphores where a barrier was
missing in percpu_up_write.

This patch improves performance on the read path of
percpu-rw-semaphores: on non-x86 cpus, there was a smp_mb() in
percpu_up_read. This patch changes it to a compiler barrier and removes
the "#if defined(X86) ..." condition.
