The PCWD cards normally use the heartbeat that is set via
the dip-switches of the card. There are only 3 switches,
thus 8 combinations that each have a certain heartbeat.
The card can however be programmed with a heartbeat from
1 till 65535 seconds. This is what our driver does: it
programs the heartbeat on the card.
There are however a lot of people that don't know that
we set the heartbeat of the watchdog card to the value
provided by the heartbeat module parameter. Instead they
think that the heartbeat value is the same as set by the
dip-switches.
This patch changes the driver so that at startup you can
take the heartbeat from the dip-switches. You do this
by setting the heartbeat module parameter to 0. This
patch also makes this the default behaviour.

Cleanup the s3c2410_wdt driver's exit point by
using labels instead of multiple returns. Also
remove the checks for the resources having been

fully allocated or not allocated the resources

Run this:
#!/bin/sh
for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
echo "De-casting $f..."
perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
done
And then go through and reinstate those cases where code is casting pointers
to non-pointers.
And then drop a few hunks which conflicted with outstanding work.

Currently this driver tracks user space clients it should send signals to. In
the presenct of file descriptor passing this is appears susceptible to
confusion from pid wrap around issues.
Replacing this with a struct pid prevents us from getting confused, and
prepares for a pid namespace implementation.

- conditionalizes procfs code upon CONFIG_PROC_FS (to reduce code size when
that option is not enabled)
- make initialization no longer fail when the procfs entry can't be
allocated (namely would initialization always have failed when
CONFIG_PROC_FS was not set)
- move the formerly file-scope static variable rtc_int_handler_ptr into
the only function using it, and makes it automatic.

Most distributions enable sysrq support but set it to 0 by default. Add a
sysrq_always_enabled boot option to always-enable sysrq keys. Useful for
debugging - without having to modify the disribution's config files (which
might not be possible if the kernel is on a live CD, etc.).
Also, while at it, clean up the sysrq interfaces.

Fix various problems pointed out by Andrew Morton and others:
* platform_device_unregister checks for NULL, no need to check here.
* Formatting fixes.
* Remove big macro and convert to a function.
* Use strcmp instead of defining a broken case-insensitive comparison,
and make the output parameter info match the case of the input one
(change "I/O" to "i/o").
* Return the length instead of 0 from the hotmod parameter handler.
* Remove some unused cruft.
* The trydefaults parameter only has to do with scanning the "standard"
addresses, don't check for that on ACPI.

Ramiro Voicu hits the BUG_ON(!pte_none(*pte)) in zeromap_pte_range: kernel
bugzilla 7645. Right: read_zero_pagealigned uses down_read of mmap_sem,
but another thread's racing read of /dev/zero, or a normal fault, can
easily set that pte again, in between zap_page_range and zeromap_page_range
getting there. It's been wrong ever since 2.4.3.
The simple fix is to use down_write instead, but that would serialize reads
of /dev/zero more than at present: perhaps some app would be badly
affected. So instead let zeromap_page_range return the error instead of
BUG_ON, and read_zero_pagealigned break to the slower clear_user loop in
that case - there's no need to optimize for it.
Use -EEXIST for when a pte is found: BUG_ON in mmap_zero (the other user of
zeromap_page_range), though it really isn't interesting there. And since
mmap_zero wants -EAGAIN for out-of-memory, the zeromaps better return that
than -ENOMEM.
