The asm-generic/bug.h __ASSEMBLY__ guarding is completely bogus, which
tripped up the powerpc build when the kernel.h include was added:

	In file included from include/asm-generic/bug.h:5:0,
			 from arch/powerpc/include/asm/bug.h:127,
			 from arch/powerpc/kernel/head_64.S:31:

	include/linux/sysinfo.h:8: Error: Unrecognized opcode: `__kernel_long_t'

Moving the __ASSEMBLY__ guard up and stashing the kernel.h include under
it fixes this up, as well as covering the case the original fix was
attempting to handle.

When the READABLE_ASM cc-option tests were added they were done so prior

This bumps the include back up so that cc-option actually runs on the

This addresses an issue encountered when a pcm is opened while
transitioning to low power state (codec->power_on == 1 &&
codec->power_transition == -1).  Add snd_pcm_power_up_d3wait to
hda_codec.  This function is used to power up from azx_open as opposed
to snd_hda_power_up used from codec_exec_verb. When powering up from
azx_open, wait for pending power downs to complete, avoiding the power
up continuing in parallel with the power down on the work queue.

The specific issue seen was with the CS4210 codec, it powers off the ADC
and DAC nid in its suspend handler.  If it is re-opened before the
~100ms power down process completes, the ADC and DAC nid are initialized
while powered down and audio is lost until another suspend/resume cycle.

ASoC: Updates for 3.5

All driver specific and fairly small.  The pxa-ssp changes are larger
than I'd like but they're build failures and are pretty clear to
inspection.

Merge hfsplus fixes from Christoph Hellwig:
 "Two small hfsplus fixes:

   - a one liner regression fix for large volume handling from Janne
     Kalliomäki.
   - a fixup for the boot image blessing feature to make it work with
     the fake "hardlinks" in hfsplus from Matthew Garrett."

* branch 'hfsplus':
  hfsplus: fix bless ioctl when used with hardlinks
  hfsplus: fix overflow in sector calculations in hfsplus_submit_bio

HFS+ doesn't really implement hard links - instead, hardlinks are indicated
by a magic file type which refers to an indirect node in a hidden
directory. The spec indicates that stat() should return the inode number
of the indirect node, but it turns out that this doesn't satisfy the
firmware when it's looking for a bootloader - it wants the catalog ID of
the hardlink file instead. Fix up this case.

When the ethernet driver was built as a module, it would lock the
machine when loaded. At boot the ethernet clks are unused, so get
turned off.  Later, when the module is loaded, the probe function
would access the hardware before the clock was restarted, and the
machine would lock. It has also been determined that when the clk is
turned off, the interface forgets its MAC address, which for most
systems, is set by the boot loader.

When the machine setup file creates a platform device for the
interface, prepare and enable the clock for the interface. This will
ensure it is not turned off. However, if the setup file only
instantiates one platform device, the other will have its clk
disabled, thus maybe saving a little power.

With commit 4d5fc58d (ARM: remove bunch of now unused
mach/io.h files), the I/O space setup was completely broken on
versatile. This patch fixes that and prepares for further
I/O space clean-up.

I/O space handling on the versatile platform is currently
broken in multiple ways. Most importantly, the ports do
not get mapped into the virtual address space at all.

Also, there is some amount of confusion between PCI I/O
space and other statically mapped MMIO registers in the
platform code:

* The __io_address() macro that is used to access the
  platform register maps to the same __io macro that gets
  used for I/O space.

* The IO_SPACE_LIMIT is set to a value that is much larger
  than the total available space.

* The I/O resource of the PCI bus is set to the physical
  address of the mapping, which is way outside of the
  actual I/O space limit as well as the address range that
  gets decoded by traditional PCI cards.

* No attempt is made to stay outside of the ISA port range
  that some device drivers try access.

* No resource gets requested as a child of ioport_resource,
  but an IORESOURCE_IO type mapping gets requested
  as a child of iomem_resource.

This patch attempts to correct all of the above. This makes
it possible to use virtio-pci based virtual devices as well
as actual PCI cards including those with legacy ISA port
ranges like VGA.

Some of the issues seem to be duplicated on other platforms.

The definition of 32-bit values in the 64-bit tilegx architecture is that

"ld4s" rather than "ld4u" to load and sign-extend for get_user().
