322392646b sh: Add missing dma_sync_single_range_for_*().
The b44 build uses these, caught by allmodconfig:

drivers/net/b44.c: In function `b44_sync_dma_desc_for_cpu':
drivers/net/b44.c:159: error: implicit declaration of function `dma_sync_single_range_for_cpu'

Follow the sparc64 change and stub them in.

eb695dbf00 sh: Fix Dreamcast DMA issues.
The current SH DMA API is somewhat broken, not correctly matching
virtual channel to the correct SH DMAC. This wasn't noticeable when
using g2 DMA for the sound driver - one channel 0 is as good as any
other! - but caused the pvr2 driver to fail.

This patch fixes the pvr2 problem and consequently fixes the sound
driver to ensure it continues to function.

This wires up kmap_coherent() and kunmap_coherent() on SH-4, and

use fixmaps for colouring instead.

The copy_user_page()/clear_user_page() implementations are moved

02ab3f7079 sh: intc - shared IPR and INTC2 controller
This is the second version of the shared interrupt controller patch
for the sh architecture, fixing up handling of intc_reg_fns[].

The three main advantages with this controller over the existing
ones are:

	- Both priority (ipr) and bitmap (intc2) registers are
	  supported
	- External pin sense configuration is supported, ie edge
	  vs level triggered
	- CPU/Board specific code maps 1:1 with datasheet for
	  easy verification

This controller can easily coexist with the current IPR and INTC2
controllers, but the idea is that CPUs/Boards should be moved over
to this controller over time so we have a single code base to
maintain.

with the ipr_data structure in a new data structure called ipr_desc.
This new structure also contains the name of the controller in struct

can use offsetof() to locate the base addresses in the irq_chip
callbacks. This strategy has much in common with the recently merged

5900711ad7 sh: pfn_valid() depends on flatmem.
pfn_valid() is already defined in the sparsemem case, so we only
need to define this for CONFIG_FLATMEM.

82f81f4784 sh: Kill off machvec aliases.
We now throw all of the machvecs in to .machvec.init and either
select one on the command line, or copy out the first (and
usually only) one to sh_mv. The rest are freed as usual.

This gets rid of all of the silly sh_mv aliasing and makes the
selection explicit rather than link-order dependent.

25f8151bdc sh: Get multiple boards in one image working again.
This tidies up the build rules and permits multiple boards to be
linked in to the same kernel. The earlier Kconfig work ensures that
the CPU configuration is consistent across the boards, as this is
the only thing that we can't do dynamically.

9655ad03af sh: Fixup machvec support.
This fixes up much of the machvec handling, allowing for it to be
overloaded on boot. Making practical use of this still requires
some Kconfig munging, however.

e08f457c7c sh: __user annotations for __get/__put_user().
This adds in some more __user annotations. These weren't being
handled properly in some of the __get_user and __put_user paths,
so tidy those up.
