9e4db1c3ee Merge branch 'platforms' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM platform updates from Russell King:
 "This covers platform stuff for platforms I have a direct interest in
  (iow, I have the hardware).  Essentially:
   - as we no longer support any other Acorn platforms other than RiscPC
     anymore, we can collect all that code into mach-rpc.
   - convert Acorn expansion card stuff to use IRQ allocation functions,
     and get rid of NO_IRQ from there.
   - cleanups to the ebsa110 platform to move some private stuff out of
     its header files.
   - large amount of SA11x0 updates:
   - conversion of private DMA implementation to DMA engine support
     (this actually gives us greater flexibility in drivers over the old
     API.)
   - re-worked ucb1x00 updates - convert to genirq, remove sa11x0
     dependencies, fix various minor issues
   - move platform specific sa11x0 framebuffer data into platform files
     in arch/arm instead of keeping this in the driver itself
   - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
     for SIR transmissions as well as FIR
   - rework sa1111 support for genirq, and irq allocation
   - fix sa1111 IRQ support so it works again
   - use sparse IRQ support

  After this, I have one more pull request remaining from my current
  set, which I think is going to be the most problematical as it
  generates 8 conflicts."

Fixed up the trivial conflict in arch/arm/mach-rpc/Makefile as per
Russell.

34800598b2 ARM: driver specific updates
These are all specific to some driver. They are typically the platform
 side of a change in the drivers directory, such as adding a new driver
 or extending the interface to the platform. In cases where there is no
 maintainer for the driver, or the maintainer prefers to have the
 platform changes in the same branch as the driver changes, the patches
 to the drivers are included as well.
 
 A much smaller set of driver updates that depend on other branches
 getting merged first will be sent later.
 
 The new export of tegra_chip_uid conflicts with other changes in fuse.c.
 In rtc-sa1100.c, the global removal of IRQF_DISABLED conflicts with
 the cleanup of the interrupt handling of that driver.

46b407ca4a remoteproc/rpmsg: new subsystem
This new subsystem provides a common way to talk to secondary processors
 on an SoC, e.g. a DSP, GPU or service processor, using virtio as the
 transport. In the long run, it should replace a few dozen vendor
 specific ways to do the same thing, which all never made it into the
 upstream kernel. There is a broad agreement that rpmsg is the way to
 go here and several vendors have started working on replacing their
 own subsystems.
 
 Two branches each add one virtio protocol number. Fortunately the
 numbers were agreed upon in advance, so there are only context changes.

Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: SoC specific updates" from Arnd Bergmann:
 "These changes are all specific to an soc family or the code for one
  soc.  Lots of work for Tegra3 this time, but also a lot of other
  platforms.  There will be another (smaller) set of soc patches later
  in the merge window for stuff that has dependencies on external trees
  or that was sent just before the merge window opened.

  The asoc tree added a few devices to the i.mx platform, which conflict
  with other devices added in the same place here.

  The tegra Makefile conflicts between a number of branches, mostly
  because of changes regarding localtimer.c, which was removed in the
  end.

12783aa077 um: Switch to large mcmodel on x86_64
x86_64 UML is unable to load modules if more than 504MiB
of memory are used.
This happens because on x86_64 the UML process has a quite high
start address (typically around 0x6000000).
If UML's memory is larger than 504MiB VMALLOC_START happens to be after
0x8000000. This is no problem unless one loads a module which was built
with R_X86_64_32S relocations.
Symbols with a location > 0x8000000 cannot be used with R_X86_64_32S

To deal with this x86_64 UML has to be compiled with -mcmodel=large
such that no R_X86_64_32S relocations are used.

04292b2cf8 um: get rid of lines_init()
move config-independent parts of initialization into
register_lines(), call setup_one_line() after it instead
of abusing ->init_str.

cfe6b7c79d um: switch line.c tty drivers to dynamic device creation
Current code doesn't update the symlinks in /sys/dev/char when we add/remove
tty lines.  Fixing that allows to stop messing with ->valid before the driver
registration, which is a Good Thing(tm) - we shouldn't have it set before we
really have the things set up and ready for line_open().

We need tty_driver available to call tty_{un,}register_device(), so we just
stash a reference to it into struct line_driver.

31efcebb7d um: fix races between line_open() and line_config()
Pull parse_chan_pair() call into setup_one_line(), under the mutex.
We really don't want open() to succeed before parse_chan_pair() had
been done (or after it has failed, BTW).  We also want "remove con<n>"
to free irqs, etc., same as "config con<n>=none".

d8c215adbf um: convert count_lock to mutex, fix a race in line_open()
If two processes are opening the same line, the second to get
into line_open() will decide that it doesn't need to do anything
(correctly) or wait for anything.  The latter, unfortunately,
is incorrect - the first opener might not be through yet.  We
need to have exclusion covering the entire line_init(), including
the blocking parts.  Moreover, the next patch will need to
widen the exclusion on mconsole side of things, also including
the blocking bits, so let's just convert that sucker to mutex...
