Some testing of DM multipath has turned up a problem with the DEVICE_WAIT
command.  In the tests, while performing a DEVICE_WAIT on a multipath device,
the command sometimes returns immediately, even though the event-number is
correct and no path-failure has occurred to trigger an event.  The problem was
tracked down to the call to schedule() in dev_wait(), which would return even
though it was not woken up by a DM table event.

This patch moves the responsibility for waiting from the ioctl interface into
the core driver, and uses wait_event_interruptible() instead of relying on
wait-queues and schedule().

I noticed that my vmlinux BSS had grown from 17k to 45k between 2.6.5 and
2.6.6.  8k was moving a pair of objects in head.S from the text section to
bss, 8k was the introduction of IRQ stacks, while the remainder (12k) was
page alignment slop, some of it spurious.  The following patch brings BSS
down to the expected 33k.

Throw the IRQ stacks into the page aligned section to avoided wasted BSS
space.  While we'd expect this to save up to 4k, this saves over 10k of BSS
here due to gcc3.3 spuriously aligning other objects in the vicinity.

Currently the get_vsid() and get_kernel_vsid() functions have a test which
enables a different VSID algorithm for debugging.  Using a dumb VSID
algorithm for stressing the hash table is a reasonable debugging tool, but
switching it at runtime makes no sense at all.  Plus it adds another test
and memory access to the performance critical SLB miss path.

This patch removes the test, replacing it with a compile time switch.  It
seems to make a measurable, although small speedup to the SLB miss path
(maybe 0.5%).

All watchdog drivers need linux/fs.h

This patch also removes the cbar usage which is unnecessary. The MMCR is
always available at 0xfffef000; there is no need to use the cbar register
(if mmcr aliasing is enabled, then the MMCR is _also_ available at
another address set by CBAR).

Clean-up (general stuff: comments, keep module parameters together, ...)
Added clear definitions for the Watchdog Timer Control Register bits
Made start, stop and keepalive return 0 if successful
Fixed nowayout behaviour so that it is consistent with other watchdog drivers
Fixed release behaviour so that it is consistent with other watchdog drivers
Added wdt_set_heartbeat function to set the timeout/heartbeat of the watchdog
Made sure that memory remapping (wdtmrctl) is done before misc_register is started
MMCR_BASE_DEFAULT was wrong (Bug 2497 reported by Sean Young)

Tested by Sean Young

When drivers starts show the correct watchdog driver info.

The following patch adds support for the ADM1030 and ADM1031 evaluation
boards to the i2c-parport and i2c-parport-light drivers. They are almost
compatible with the already supported ADM1025 and ADM1032 boards, except
that the ADM1032 board needs some pins to be set high to draw its power,
while the same pins power up heating resistors on the ADM1031 board. I
considered it was a bit dangerous to do that by default, so I ended up
with two different device definitions, one with powering pins set, and
one with these pins cleared.

 In drivers/pci/probe.c::pci_scan_bridge() the call for pci_alloc_child_bus()
can return NULL, but it is not handled by the function (detected by
Coverity's checker).

 The patch bellow fix that returning `max' if we got the NULL, but
I do not know if it is right. I guess it is, because in that case
the function will act in the same way as with `pass != 0'.

This patch fixes throttling problems in the ftdi_sio driver for the
2.6 kernel.  The old throttling mechanism (unlinking the read urb)
often failed to work, and even it did work, would lose any data
held in the transfer buffer.  The new mechanism presented here is
based on what the whitehead driver does (defer processing and
resubmitting of the read urb until unthrottled).

uses normal negative error codes, including -ENOTCONN to indicate device

Currently all devices are resumed at system resume time, including any
that were individually powered off ("at runtime") prior to the system
suspend.  In certain cases it can be nice to force back on individually
suspended devices, such as the display, but hopefully this policy can be
left up to userspace power managers; the kernel should probably honor
the settings previously made by userspace/drivers.  This seems
preferable to requiring a power-conscious system to re-suspend devices
after a system resume; furthermore, for certain platforms (such as
XScale PXA27X) there can be disastrous consequences of powering up
devices when the system is in a state incompatible with operation of the
device.

Suggested patch does this:

(1) At system resume, checks power_state to see if the device was
suspended prior to system suspend, and skips powering on the device if
so.

(2) Does not re-suspend an already-suspended device at system suspend
(using a different method than is currently employed, which reorders the
list, see #3).

(3) Preserves the active/off device list order despite the above changes
to suspend/resume behavior, to avoid dependency problems that tend to
occur when the list is reordered.
