dma branching is enabled by extending the current setup_frame_dma()

used.

As a result, pxafb_dma_buff.dma_desc[], pxafb_dma_buff.pal_desc[]
and pxafb_info.fdadr[] are doubled.

[ARM] pxafb: allow pxafb_set_par() to start from arbitrary yoffset

Note the var->yres_virtual is only re-calculated from the fix.smem_len
when text mode acceleration is enabled (which is default), this is due
to the issue as Russell suggested below:

Previous experience of doing this with the X server and acornfb is that
it causes all sorts of problems - it seems to force the X server into
assuming that the framebuffer should be panned no matter what settings
you ask it for.

The recommended workaround (implemented in acornfb) is to only do these
kinds of adjustments if text mode acceleration is enabled.  IIRC, the X
server should be disabling text mode acceleration when it maps the
framebuffer.  I seem to remember that there are X servers which forget
to do that though.

order:

1. <xres> x <yres> x <bits_per_pixel> by default, which is the backward
   compatible way

2. size specified in platform data

3. size specified in module parameter 'options' string or specified in
   kernel boot command line (see updated Documentation/fb/pxafb.txt)

And now since the memory is allocated from system memory, the pxafb_mmap
can be removed and the default fb_mmap() should be working all right.

Also, since we now have introduced the 'struct pxafb_dma_buff' for DMA
descriptors and palettes, the allocation can be separated cleanly.

NOTE: the LCD DMA actually supports chained transfer (i.e. page-based
transfers), to simplify the logic and keep the performance (with less
TLB misses when accessing from memory mapped user space), the memory
is allocated by alloc_pages_*() to ensures it's physical contiguous.

Changes made as suggested by Eric Miao (including fix to map_io
silly mistake!).

Originally designed by Intel, now sold by Crossbow (www.xbow.com).

Very little actually on board. The patch includes sensors and
similar as found on commonly occurring daughter boards.

Some of the drivers are not in mainline as yet as they are either
part of the IIO subsystem or need a lot of work before submission.
What is the position wrt to putting them in i2c board configs etc?

Support for these boards has been maintained outside the kernel
for a long time, but now that there is a good da9030 pmic driver
available the last major hurdle no longer exists.

All comments welcomed.

The Imote2's big brother (stargate2) will follow once any problems
with this one have been cleaned up and a few bits and bobs have
been added to the da903x driver. Hopefully the cc2420 driver will
get cleaned up and submitted in the not too distant future as
well.

459fc208abd1b365fa013c17d433dfb5b4bc1e3a (cpufreq: remove
policy->governor setting in drivers initialization), this patch
introduces an option (called "pxa255_turbo_table") to select either
the "run" or "turbo" frequency table.

It also cures the runtime warning that was printed each time the

   inverted in GPDR2, as well as their alternate function bits being

2. there is no easy way to decide if the processor is a pxa26x or a
   pxa250/pxa255 at run-time, so the assumption here is the pxa26x
   will be treated as one of the pxa25x variants, and board code
   should have a better knowledge of the processor it is featured

Introduce pxa26x_init_irq() for the second purpose, and treat the
additional GPIOs > 85 on PXA25x specially.

Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code
a bit when PXA26x support isn't needed. Board config options have
to select this to enable the support for PXA26x.

isn't selected.

The problem is that compat_arch_ptrace() enters with an addr value of
type compat_ulong_t and calls translate_usr_offset() to translate the
address offset into a struct pt_regs offset like this:

addr = translate_usr_offset(addr)

this means that any return value of translate_usr_offset() is stored
back as compat_ulong_t type into the addr variable.

But since translate_usr_offset() returns -1 for invalid offsets, addr
can now get the value 0xffffffff which then fails the next return-value
sanity check and thus the kernel tries to access invalid memory:

if (addr < 0)
break;

Fix this bug by modifying translate_usr_offset() to take and return
values of type compat_ulong_t, and by returning the value
"sizeof(struct pt_regs)" as an error indicator.

Additionally change the sanity check to check for return values
for >= sizeof(struct pt_regs).

This patch survived my compile and run-tests.

TPROXY: supply a struct flowi->flags argument in inet_sk_rebuild_header()

    inet_sk_rebuild_header() does a new route lookup if the dst_entry
    associated with a socket becomes stale. However inet_sk_rebuild_header()
    didn't use struct flowi->flags, causing the route lookup to
    fail for foreign-bound IP_TRANSPARENT sockets, causing an error
    state to be set for the sockets in question.
