Add ICS307 clock support

Patch from Ben Dooks

This fixes the following with s3c24xx power management:

- debugging needs UARTs enabled, to re-enabled UART clocks,
  save their state over suspend, and add this to the current
  documentation

- update the documentation on pm initialisation

- fix bug reported by Dimitry Andric where __raw_writel()
  has arguments the wrong way around

- fix typo (lower-case letter in S3C2410_GATSTUs2_OFFRESET)
  from Dimitry Andric

- apply Arnaud Patard's patch for pm call types

- move bits of resume code to use printk(KERN_DEBUG) as they
  are potentially before the UART resume, and are not critical
  if the system fails to re-start.

Add CONFIG_CPU_CACHE_VIVT and CONFIG_CPU_CACHE_VIPT and use
these to conditionalise cache_is_xxx().  This allows unnecessary
cache handling code to be removed by the compiler.

Experimented a bit more with mounting a bad ext2 filesystem.

An immediate crash was caused by zero EXT2_BLOCKS_PER_GROUP(sb).
The patch below (relative to 2.6.9) adds a few checks to make sure
that things we divide by are not zero.

There is a similar problem reported by s390 people where we see parent
kobject (directory) going away before child kobject (sub-directory). It
seems kobject code is able to handle this, but not the sysfs. What could
be happening that in sysfs_remove_dir() of parent directory, we try to
remove its contents. It works well with the regular files as it is the
final removal for sysfs_dirent corresponding to the files. But in case
of sub-directory we are doing an extra sysfs_put().  Once while removing
parent and the other one being the one from when sysfs_remove_dir() is
called for the child.

The following patch worked for the s390 people, I hope same will work in
this case also.


o Do not remove sysfs_dirents corresponding to the sub-directory in
  sysfs_remove_dir(). They will be removed in the sysfs_remove_dir() call
  for the specific sub-directory.

"clear_buffer_locked()" is just a nicer name for a clear-bit, and

This is a relatively small changeset, to address small nagging problems.
Andrew pointed me at the double registration specifically, so I had to do
something about it. At least now Fabio's box won't collapse if he configures
UB by mistake. Also, a few people complained that the help text was
misleading.

I have not done anything about the oops on disconnect which happens to
Martin Schlemmer. It's next. After that I can get to Peter Jones' CD
burning patch and doing resets.

- Fix double kobject registration and eventual oops on unplug if a device
  is not cooperating.
- Add a reference to usb-storage into the configuration help.
- Just upping timeouts fixes my ZIP drive.
- Max out the diag (trace) file size.
- Set capacity to zero in case the media is absent. It works in 2.4.10-rc1.

Looks like kobject_uevent_init is executed before netlink_proto_init and
consequently always fails.  Not cool.

Attached patch switches the initialization over from core_initcall (init
level 1) to postcore_initcall (init level 2).  Netlink's initialization
is done in core_initcall, so this should fix the problem.  We should be
fine waiting until postcore_initcall.

Also a couple white space changes mixed in, because I am anal.

This clarifies more of the x86 caller/callee stack ownership
issues by making the exception and interrupt handler assembler
interfaces use register calling conventions.

System calls still use the stack.

 df_02_bus_rescan_devcies_fix.patch

 bus_rescan_devices() eventually calls device_attach() and thus
requires write locking the corresponding bus.  The original code just
called bus_for_each_dev() which only read locks the bus.  This patch
separates __bus_for_each_dev() and __bus_for_each_drv(), which don't
do locking themselves, out from the original functions and call them
with read lock in the original functions and with write lock in
bus_rescan_devices().

Add the sysfs path of the physical device to the hotplug event of class
and block devices. This should solve the userspace issue not to know if
the device is a virtual one and the "device" symlink will never be created,
but we sit there and wait for it to show up not knowing when we should
give up.

Also the bus name is added to the hotplug event, so we don't need to
reverse lookup in the /sys/bus/* directory which bus our physical
device belongs to. This is e.g. the value matched against the BUS= key,
that may be used in an udev rule.

We need to open the gap between congestion on/off a little bit, or we
risk burning many cycles continually putting processes on a wait queue
only to wake them up again immediately. This was observed with CFQ at
