Add exports and change some __init to __devinit for dynamic OF and pci
hotplug, from John Rose and Linda Xie

The ppc64 NUMA code has a sign extension problem.  We would sign extend tmp1
when assigning it to start.  Fix this by making tmp1 unsigned.

Attached is a patch which replaces all the uses of the old device tree API in
arch/ppc64.  Patch is against 2.6.0-test5 (cset 1.1328) from ameslab bk, plus
the patch from my previous message.  I've tested this on a pSeries LPAR.

From: Anton Blanchard <anton@samba.org>

This is an adaptation of the new Open Firmware device tree traversal API from
ppc32, originally written by Benjamin Herrenschmidt.  This patch is against
2.6.0-test3, but should apply ok to the latest 2.5 ameslab tree.

These functions are meant to be SMP-safe alternatives to the current set of
query/traversal routines (find_devices, find_type_devices, et al).

From: Anton Blanchard <anton@samba.org>

Upcoming partition firmware requires the use of the ibm,phandle property for
matching device nodes.  Add a new field in device_node to contain this data.

Convert atkbd to the new style of option parsing.

If compiled as a module new option names are: set, softrepeat, reset.

If built into the kernel options must be prepended with "atkbd." prefix,
like "atkbd.softrepeat"

From: Dmitry Torokhov <dtor_core@ameritech.net>

With Vojtech's approval adjusted psmouse option names by dropping psmouse_
prefix.

If psmouse is compiled as a module new option names are: proto, rate,
resetafter, resolution, smartscroll

If psmouse is built in the kernel the prefix "psmouse." is required in
front of an option, like "psmouse.proto"

Also, since we are changing all names, killed psmouse_noext completely

From: Dmitry Torokhov <dtor_core@ameritech.net>

With Vojtech's approval adjusted i8042 option names by dropping i8042_
prefix.

If i8042 is compiled as a module new option names are: direct, dumbkbd,
noaux, nomux, reset, unlock.

If i8042 is build in the kernel the prefix "i8042." is required in front of
an option, like "i8042.reset"

raw.c has a refcounting bug (patch attached).

As for the theory...  If you have a pathname - use filp_open() or
open_bdev_excl() and be done with that.  bdget() et.al.  are OK only if you
really have nothing better than device number and that's a situation that
should be avoided unless you really have no choice.

Said that, we have the following primitives:

* lookup_bdev(): takes a pathname, returns a reference to block_device.

* bdget(): takes a number, returns a reference to block_device.

* blkdev_get(): takes a reference to block_device and opens it.  If open
  fails - drops the reference to block_device passed to it.

* blkdev_put(): takes a reference to block_device and closes it.  The
  reference is dropped.

* bdput(): drops a reference to block_device.

Note that behaviour of blkdev_get() and blkdev_put() is such that it makes
for minimal cleanup code.

bd_claim()/bd_release() is the exclusion mechanism - that's what mount,
swapon, open with O_EXCL, etc.  are using to avoid stepping on each others
toes.  bd_claim() claims bdev for given owner; if it's already owned and
not by the same owner you'll get -EBUSY.  bd_release() reverts the effect
of bd_claim().  Note that if you claim the thing N times (with the same
owner, obviously), you'll need N bd_release() before it stops being owned.

raw.c grabbed a reference to bdev only after blkdev_get().  If blkdev_get()
failed (e.g.  media being absent), you've got an unbalanced bdput().

	Patch switches cramfs_read() to direct use of pagecache and
eliminates all messing with buffer_heads.  Fixes the interaction with
ramdisk (there set_blocksize() simply killed the ramdisk contents) and
gets code less brittle overall.
