Patch from Ian Campbell
On PXA255 there is no way to disable the watchdog. Turning off OIER[E3]
as suggested in the existing comment does not work.
I posted a note to the ARM mailing list a little while ago asking for
opinions from people using SA1100. There was one reponse from Nico who
believes that the SA1100 is the same as the PXA255 in this respect.
You also asked me to involve the watchdog maintainer which I tried to
do but didn't hear anything back. There are only a couple of other
drivers which can't stop the watchdog and there seems to be no
consistancy regarding printing an error etc. I decided to print
something since that matches the case for all the other drivers when
NOWAYOUT is turned on.
Also, I changed the device .name to "watchdog" like most of the other
watchdogs. udev uses it as the device name (by default) and spaces etc.
get in the way.
Superceded 2833/1 because 2.6.13-rc4 caused rejects.

When leaving S3 state, the AGP bridge may not have all PCI configuration
registers set in the same way as they were at boot. This should be fixed
by pci_restore_state - however, the APBASE register cannot be set to
conflict with the APSIZE register. If APSIZE is larger than it was before
suspend, pci_restore_state will not restore APBASE correctly. The attached
patch adds an extra item to the agp_bridge_data structure and uses it to
store the value of APBASE. On resume, this is then written after APSIZE
has been set. This patch only touches the path used for Intel chipsets
without integrated graphics, and may need to be extended to work with the
others.
Without this patch, I get the symptoms described in bug 4921 - APBASE ends
up overlapping various PCI devices, and as a result they fail to work after
resume.

`gcc -W' likes to complain if the static keyword is not at the beginning of
the declaration. This patch fixes all remaining occurrences of "inline
static" up with "static inline" in the entire kernel tree (140 occurrences in
47 files).
While making this change I came across a few lines with trailing whitespace
that I also fixed up, I have also added or removed a blank line or two here
and there, but there are no functional changes in the patch.

This patch provides a new device driver for the Infineon SLD 9630 TT Trusted
Platform Module (TPM 1.1b) [1] which is embedded on Intel- mainboards or in
HP/ Fujitsu-Siemens / Toshiba-Notebooks. A nearly complete list where this
module is integrated in can be found in [2].
This kernel module acts as a communication gateway between the linux kernel
and the hardware chip and fits the TPM-specific interfaces created by IBM in
drivers/char/tpm/tpm.h
Further information about this module and a list of succesfully tested and
therefore supported hardware can be found at our project page [3].

genrtc.c won't compile on ppc64. Seems that ppc32 does support it though?
We do this wrong btw - we should be selecting GEN_RTC in each
arch/xxx/Kconfig.

Usually the device IDs are given in hex. This one is a bit strange: it is
without 0x in the first place and used with it some lines later. I suspect

The call appears to come from process context so kernel_power_off
should be safe. And acpi_power_off won't necessarily work if you just
call machine_power_off.

If a watchdog driver has decided it is time to reboot the system
we know something is wrong and we are in interrupt context
so emergency_reboot() is what we want.

sysrq calls into the reboot path from an interrupt handler
we can either push the code do into process context and
call kernel_restart and get a clean reboot or we can simply
reboot the machine, and increase our chances of actually
rebooting. emergency_reboot() seems like the closest match
to what we have previously done, and what we want.

and causes release_dev() to hang since it can't get the ref count to 0.
