No need for generic cache with only one user.
Keep a simple hash of deviceids in the filelayout driver.

Use our own async error handler.
Mark the layout as failed and retry i/o through the MDS on specified errors.
Update the mds_offset in nfs_readpage_retry so that a failed short-read retry
to a DS gets correctly resent through the MDS.

Attempt a pNFS file layout read by setting up the nfs_read_data struct and
calling nfs_initiate_read with the data server rpc client and the
filelayout rpc call ops.
Error handling is implemented in a subsequent patch.

Introduce a data server set_client and init session following the
nfs4_set_client and nfs4_init_session convention.
Once a new nfs_client is on the nfs_client_list, the nfs_client cl_cons_state
serializes access to creating an nfs_client struct with matching properties.
Use the new nfs_get_client() that initializes new clients.

Change the _mapcount value indicating PageBuddy from -2 to -128 for
more robusteness against page_mapcount() undeflows.
Use reset_page_mapcount instead of __ClearPageBuddy in bad_page to
ignore the previous retval of PageBuddy().

This patch changes the implementation of strnlen_user in include/asm-generic/uaccess.h.
Originally, it calls strlen() function directly, which may not correctly handle the access of
user space in most mmu-enabled architectures.
New __strnlen_user is added for using as an architecture specific function.

The definitions for the PC-style PIO functions in asm-generic/io.h were
meant as dummies so you could compile code on architectures without
ISA and PCI buses. However, unicore32 actually wants to use them
with a real PCI bus, so they need to be defined to actually address
the register window holding the I/O ports.

There's nothing worth hiding under the ifdef in the platform DMA
definitions, and we certainly don't want board code adding this in to
their platform data definitions, so we always expose the slave rx/tx
and device pointer members instead.

All of the muxed IRQs presently populate the IRQ array verbosely, this

All users of the platform port data specify a mapbase where the driver
later derives the membase from. Now that UPF flags are taken in to
account for generic ioremapping we can kill off the port-specific membase
clobbering and simply use the generic paths.
This derives from a time when sh64 was not capable of using the generic
ioremap implementation and had employed early bolted DTLB mappings for
port access, which is no longer an issue.

Now that the clock string isn't used by the driver anymore, kill it off
from the platform structure.

Supports YCbCr420sp, YCbCr422sp, and YCbCr44sp, formats
(bpp = 12, 16, and 24) respectively.
When double-buffering both Y planes appear before the C planes (Y-Y-C-C),
as opposed to Y-C-Y-C.
Set .nonstd in struct sh_mobile_lcdc_chan_cfg to enable YUV mode, and use
.bpp to distiguish between the 3 modes.
The value of .nonstd is copied to bits 16-31 of LDDFR in the LCDC and
should be set accordingly.
.nonstd must be set to 0 for RGB mode.
Due to the encoding of YUV data, the framebuffer will clear to green
instead of black.
In YUV 420 mode, panning is only possible in 2 line increments.
Additionally in YUV 420 mode the vertical resolution of the framebuffer
must be an even number.

This commit changed an internal radeon structure, that meant a new driver
in -next had to be fixed up, merge in the commit and fix up the driver.
Also fixes a trivial nouveau merge.

Userspace has a legitimate requirement to use a delta that points to
outside of the target bo, and so we need to enable this. (As this is an
abi break, albeit a relaxation of the current restrictions, mark the change
with a new flag.)

We're coming to see a need to have a set of generic capability checks in
the core DRM, in addition to the driver-specific ioctls that already
exist.
This patch defines an ioctl to do as such, but does not yet define any
capabilities.
