These messages are a regression compared with 2.6.24, which did not
flood the syslog with them.

The actual underlying problem was introduced in 2.6.23, when somebody
made the string parsing no longer accept nul-terminated strings as a
valid input to store_uevent().

Eg.  "add\0" was valid prior to 2.6.23, where the code regressed to
require "add" without the '\0'.

This patch fixes the 2.6.23 / 2.6.24 regressions, by having the code
once again tolerate the trailing '\0', if present.

According to GregKH, this mainly affects older Ubuntu systems, such as
the one I have here that requires this fix.

When getting disconnected we need to release eventual grabs on the
underlying input device as we also release the input device itself.
Otherwise, we would try to release the grab when the client that
requested it closes its handle, accessing the input device which
might already be freed.

 a) every bitwise declaration will give a unique type; use typedefs.

 b) no need to bother with the stuff pointed to by iomem pointers,
    unless it's accessed directly.  noderef will force us to use helpers

This patch fixes bits of the DRM so to make the radeon DRI work on
non-cache coherent PCI DMA variants of the PowerPC processors.

It moves the few places that needs change to wrappers to that
other architectures with similar issues can easily add their
own changes to those wrappers, at least until we have more useful
generic kernel API.

This interface was originally designed wrong, confusing bit-fields and
integers, major brown paper bag going back many years...

But userspace only ever used 4 values so fix the interface for new
users and fix the implementation to deal with the 4 values userspace
has ever emitted (0x1, 0x2, 0x3, 0x6).

This reverts commit b140b99c.

[ conflict in drivers/ide/ide-probe.c fixed manually ]

It turned out that probing order change causes problems for some drives:

	http://bugzilla.kernel.org/show_bug.cgi?id=10239

Since root causes are still being investigated and are unlikely to be fixed
before 2.6.25 lets revert this change for now.  As a result cable detection
becomes less reliable when compared with 2.6.24 but the affected drives are
useable again.

There have been reported regressions of the SIL 680 driver when using MMIO, so
this makes it only try MMIO on Cell blades where it's known to be necessary
(the host bridge doesn't do PIO on these).

We'll try to find the root problem with MMIO separately.
