Currently, when we get a prefixpath as part of mount, the kernel only
changes the first character to be a '/' or '\' depending on whether
posix extensions are enabled. This is problematic as it expects
mount.cifs to pass in the correct delimiter in the rest of the
prefixpath. But, mount.cifs may not know *what* the correct delimiter
is. It's a chicken and egg problem.
Note that mount.cifs should not do conversion of the
prefixpath - if we want posix behavior then '\' is legal in a path
(and we have had bugs in the distant path to prove to me that
customers sometimes have apps that require '\'). The kernel code
assumes that the path passed in is posix (and current code will handle
the first path component fine but was broken for Windows mounts
for "deep" prefixpaths unless the user specified a prefixpath with '\'
deep in it. So e.g. with current kernel code:
1) mount to //server/share/dir1 will work to all server types
2) mount to //server/share/dir1/subdir1 will work to Samba
3) mount to //server/share/dir1\\subdir1 will work to Windows
But case two would fail to Windows without the fix.
With the kernel cifs module fix case two now works.

This acts as a reversion of 1c6b2ca5e0939bf8b5d1a11f1646f25189ecd447 in
the case of UP SH-4, where we still have the risk of a multiple hit
between the slow and fast paths. As seen on SH7780.

Use generic_io_base to point out the pci io window, and make sure the
highest port address used is SH7751_PCI_IO_SIZE - 1.
This patch fixes pci io port access for the r2d boards - CONFIG_8139TOO_PIO
now works as expected. So does the alsa driver for CMI8738.

This patch is a fix to make sure readsN/writesN are used over insN/outsN for
ioreadN_rep/iowriteN_rep.
The current state of the sh io code is that mmio operations like readN/writeN
and ioreadN/iowriteN are unaffected by the value of generic_io_base. This is
different fom port based io like inN/outN which gets adjusted using the value
in generic_io_base.
Without this patch ioreadN_rep/iowriteN_rep get their addresses adjusted.
The address for mmio access is adjusted using generic_io_base. This is wrong.
The ata core code currently crashes if generic_io_base is set.
This patch changes ioreadN_rep/iowriteN_rep to follow the same rules as the
rest of the mmio operations, ie don't adjust using generic_io_base.

This patch makes sure ctrl_inN/outN are used instead of inN/outN for on chip
pci registers. Without this patch addresses may be adjusted using the value
in generic_io_base. This patch makes it possible to set generic_io_base and
have pci without reading and writing all over the place.

linux/swap.h really wants to include linux/pagemap.h in order to satisfy
the page_cache_release()/release_pages() definition requirements when
CONFIG_SWAP=n. Unfortunately the code in question contains:
/* only sparc can not include linux/pagemap.h in this file
* so leave page_cache_release and release_pages undeclared... */
#define free_page_and_swap_cache(page) \
page_cache_release(page)
#define free_pages_and_swap_cache(pages, nr) \
release_pages((pages), (nr), 0);
so it looks like we're stuck with doing it in asm/tlb.h instead, as
others already do (ARM, CRIS, etc.). Grumble.

Improve device detection for maple through longer delay

The idea is that we want to get rid of the in/out/readb/writeb callbacks from
the machvec and replace that with simple inline read and write operations to
memory. Fast and simple for most hardware devices (think pci).
Some devices require special treatment though - like 16-bit only CF devices -
so we need to have some method to hook in callbacks.
This patch makes it possible to add a per-device trap generating filter. This
way we can get maximum performance of sane hardware - which doesn't need this
filter - and crappy hardware works but gets punished by a performance hit.
V2 changes things around a bit and replaces io access callbacks with a
simple minimum_bus_width value. In the future we can add stride as well.

This patch adds basic support for the Migo-R board.
Only simple stuff provided by the cpu specific sh7722 code is in place now,
like serial console port, timers and usb gadget. There is also partial support
for the smc91c111 ethernet controller - unfortunately some driver header file
also needs patching (not included here) to make the driver get IRQ sense
information from the platform data.

Replacement second-in-series patch:
This patch fixes up memory leaks and, by delaying initialisation, makes
device detection more robust.
It also makes clearer the difference between struct maple_device and
struct device, as well as cleaning up the interrupt request code
(without changing its function in any way).
Also now removes redundant registration checking.
