My copying of linux/init.h didn't go far enough. The definition of
__used singled out gcc minor version 3, but didn't care what the major
version was. This broke when unit-at-a-time was added and gcc started
throwing out initcalls.
This results in an early boot crash when ptrace tries to initialize a
process with an empty, uninitialized register set.

Add in console polling hooks for the cpm uart for use with kgdb and

Signed-off-by: Jason Wessel <jason.wessel@windriver.com>
CC: galak@kernel.crashing.org
This patch removes the old kgdb reminants from ARCH=powerpc and
implements the new style arch specific stub for the common kgdb core
interface.
It is possible to have xmon and kgdb in the same kernel, but you
cannot use both at the same time because there is only one set of
debug hooks.
The arch specific kgdb implementation saves the previous state of the
debug hooks and restores them if you unconfigure the kgdb I/O driver.
Kgdb should have no impact on a kernel that has no kgdb I/O driver
configured.

This patch completely removes the dependency of usbkbd and usbmouse drivers
on usbhid code.
usbkbd/usbmouse drivers are not needed in the vast majority of cases anyway,
and they shouldn't be loaded in standard configurations at all. They are supposed
to be as trivial as possible, and searching for HID_QUIRK_IGNORE can even be
bad in some cases.

Some Logitech mice have a tilt wheel which register as HWHEEL buttons.
The events are positive for a click to the right and negative for a

This is alternative implementation of sg content iterator introduced
by commit 83e7d317... from Pierre Ossman in next-20080716. As there's
already an sg iterator which iterates over sg entries themselves, name
this sg_mapping_iterator.
Slightly edited description from the original implementation follows.
Iteration over a sg list is not that trivial when you take into
account that memory pages might have to be mapped before being used.
Unfortunately, that means that some parts of the kernel restrict
themselves to directly accesible memory just to not have to deal with
the mess.
This patch adds a simple iterator system that allows any code to
easily traverse an sg list and not have to deal with all the details.
The user can decide to consume part of the iteration. Also, iteration
can be stopped and resumed later if releasing the kmap between
iteration steps is necessary. These features are useful to implement
piecemeal sg copying for interrupt drive PIO for example.

Add a couple of tests to make sure the host driver handles highmem

are out of reach for the hardware (OTOH, so will any other highmem
allocation in the kernel).
