Pull regulator fixes from Mark Brown:
 "A few fixes for teardown issues that will be rarely seen, plus a fix
  for a silly bug in regulator_is_supported_voltage() which shows how
  often the answer to the question should be false.

 "To avoid unnecessary risk and work the preemption fixes are combined
  with some preparatory work that isn't strictly required.  So it's
  really just 3 fixes:

   - Get is_compat_task() to do the right thing while simplifying it.
     The unnecessary complexity hid a rarely striking bug which could be
     triggered by ext3/ext4 under certain circumstances.
   - Resolve a preemption issue in the irqflags.h functions for kernels
     built to support pre-MIPS32 / pre-MIPS64 Release 2 processors.
   - Fix the interrupt number of the MIPS Malta's CBUS UART."

  is RCU usage fix."

The recent change for USB-audio disconnection race fixes introduced a
mutex deadlock again.  There is a circular dependency between
chip->shutdown_rwsem and pcm->open_mutex, depicted like below, when a
device is opened during the disconnection operation:

A. snd_usb_audio_disconnect() ->
     card.c::register_mutex ->
       chip->shutdown_rwsem (write) ->
         snd_card_disconnect() ->
           pcm.c::register_mutex ->
             pcm->open_mutex

B. snd_pcm_open() ->
     pcm->open_mutex ->
       snd_usb_pcm_open() ->
         chip->shutdown_rwsem (read)

Since the chip->shutdown_rwsem protection in the case A is required
only for turning on the chip->shutdown flag and it doesn't have to be
taken for the whole operation, we can reduce its window in
snd_usb_audio_disconnect().

When regulator_register fails and exits through the scrub path the
regulator_put function was called whilst holding the
regulator_list_mutex, causing deadlock.

can be safely called whilst holding the mutex, replacing the
aforementioned call.

I have been maintaining the i2c subsystem for 7 years now, it's about
time to let someone else take over. Just before I leave, I would like
to thank several individuals who made this possible at all:

* Greg Kroah-Hartman, for his faith in my potential subsystem
  maintainer skills. Greg, I hope I met your expectations.
* Late David Brownell, for helping me convert the i2c subsystem to the
  standard device driver model. Rest in peace David, we're missing you.
* Ben Dooks, for stepping in when I asked for someone to take care of
  the huge flow of new i2c adapter drivers for embedded systems.
* Wolfram Sang, for joining the crew when it became clear that there
  was more review work than Ben and myself could deal with.

I hope I did not forget anyone, please forgive me if I did.

Another big thank is due to Wolfram again, who quickly proposed to
take over as the main i2c subsystem maintainer. This will allow for a
smooth and fast transition.

Note that I will keep maintaining all I2C/SMBus controller drivers for
PC systems as well as a few others. I am hereby updating MAINTAINERS
accordingly. I'll also keep maintaining user-space i2c-tools.

The CBUS UART's interrupt number was wrong conflicting with the interrupt
being tied to the Intel PIIX4.  Since the PIIX4's interrupt is registered
before the CBUS UART which is not being used on most systems this would
not be noticed.

Attempts to open the ttyS2 CBUS UART would result in:

genirq: Flags mismatch irq 18. 00000000 (serial) vs. 00010000 (XT-PIC cascade)
serial_link_irq_chain: request failed: -16 for irq: 18

QEMU first retrieves the supported features via KVM_GET_SUPPORTED_CPUID
and then sets them later. So guest's X86_FEATURE_XSAVE should be masked
out on hosts without X86_FEATURE_XSAVE, making kvm_set_cr4 with
X86_CR4_OSXSAVE fail. Userspaces that allow specifying guest cpuid with
X86_FEATURE_XSAVE even on hosts that do not support it, might be
susceptible to this attack from inside the guest as well.

Allow setting X86_CR4_OSXSAVE bit only if host has XSAVE support.

  2) TIPC and several network drivers erroneously call tasklet_disable

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

  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.

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 a850a755, "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

If an irq is being unlinked concurrently with leon_handle_ext_irq,
irq_map[eirq] might be null in leon_handle_ext_irq. Make sure that
this is not dereferenced.
