If there are no writes for 20 milliseconds, write out superblock
to mark array as clean.  Write out superblock with
dirty flag before allowing any further write to succeed.

If an md thread gets signaled with SIGKILL, reduce the
delay to 0.


Also tidy up some printk's and make sure writing the
superblock isn't noisy.

The md_recoveryd thread is responsible for initiating and cleaning
up resync threads.
This job can be equally well done by the per-array threads
for those arrays which might need it.

So the mdrecoveryd thread is gone and the core code that
it ran is now run by raid5d, raid1d or multipathd.

We add an MD_RECOVERY_NEEDED flag so those daemon don't have
to bother trying to lock the md array unless it is likely
that something needs to be done.

Also modify the names of all threads to have the number of
md device.

It is needed for kernel_fpu_*

Md uses ->recovery_running and ->recovery_err to keep track of the
status or recovery.  This is rather ad hoc and race prone.

This patch changes it to ->recovery which has bit flags for various
states.

It is (now) too trivial to even have an inline.

This patch converts the file to use C99 initializers.

From: Angus Sawyer <angus.sawyer@dsl.pipex.com>

Mainly straightforward convert of sprintf -> seq_printf.  seq_start and
seq_next modelled on /proc/partitions.  locking/ref counting as for
ITERATE_MDDEV.

pos == 0 -> header
pos == n -> nth mddev
pos == 0x10000 -> tail

Whenever a ITERATE_MDDEV loop is exitted abnormally
we need to mddev_put the current mddev.  There was
one point in md_do_sync where we didn't so use counts
became wrong.

set. A few versions of gcc-2.96 generate seriously incorrect code.

This patch creates a new include directory include/media, populates
it with a few files header files and fixups the affected drivers to
compile with the new directory layout.

The directory is intented to be used for (kernel-internal) header files
of the media drivers (which are sitting below drivers/media).  For now
the video-buf.h (mm helper), tuner.h (tv/radio tuner) and audiochip.h
(tv sound decoder drivers) header files are moved.  Some more header
files from the dvb folks will likely follow.

This patch deletes the MIN/MAX macros from audiochip.h
and fixes all users of these macros to use the kernels
min/max macros instead.

Allow auto-unplugging to work for devices that do it themselves.

Auto-unplugging - and blk_unplug_work in particular - assumes that the device
uses "generic_unplug_device" for unplugging, but some devices don't.  md
crashes.

So blk_unplug_work should use ->unplug_fn

From Ben Collins

Used as manual trigger for device/driver binding, so drivers can claim 
devices that are present but failed to be bound. In case of ieee1394, this
can happen if two computers are attached to a device - the second one won't
be able to claim it until the first detaches. 

Changed device_attach() to return 1 when a driver was bound to a device. 
Makes it so bus_rescan_devices() can return the number of devices attached.
Tested this with ieee1394 over a bus reset and it worked as expected.

- Don't d_delete() files when removing a directory - they must still be 
  hashed when dput() reaps them, and it will __d_drop() them anyway.

- Don't d_invalidate() the directory on removal. 

- do simple_rmdir() after d_delete() on directory. 

- Remove extra dput(), which was causing refcount to go negative, causing 
  an oops when someone tried to create the directory again.

- Make sure we don't d_delete() or do extra dput() on file when updating, 
  either.

The old adap_lock and driver_lock could deadlock and there was a bunch
of stuff that was horribly racy.  The new locking scheme is from
lm_sensors CVS but I had to fix quite a few bugs to make this work.

This one is from lm_sensors CVS and mostly cosmetic changes.  I it up a
bit to compile properly under latest 2.5.

another bunch of IDs appeared in lm_sensors CVS lately..

This somehow got lost in the uClinux merge.

It's the _device_ filesystem, so regular files are grossly misplaced
here.  Fortauntely only one driver actually tries to use it (microcode)
and it's works fine with  a regular miscdevice as well.

Sorry, the devs_only() patch accidentally included the devfs-portion
of the DEVFS_FL_AUTO_DEVNUM patch.  This patch contains the remaining
parts.

The new slab poisoning code broke kmem_cache_size(), it now returns
a too large size as the poisoning area after the object is includes.
XFS's kmem_zone_zalloc thus overwrites exactly that area and triggers
the new checks everytime such an object is freed again.

I don't recommend using XFS on BK-current without this patch applied :)

This patches fixes the m68knommu 68360 serial driver to use the
work_struct, not the obsoleted workqueue.

This patch moves common ColdFire vector and timer procesing code from
the local per-processor config.c for the 5206 ColdFire sub-architecture.
All ColdFire CPU's have the same timer and basic vector setup, seems
crazy to repeat this code for each of 6 ColdFire CPU varients.

This patch also removes the reset button support, this is now moved to
a proper device driver, where it belongs.

This patch creates common timer setup and handling code for the m68knommu
ColdFire CPU sub-architecture. All 6 ColdFire CPU varients contain the
same hardware timers. Currently each sub-arch has its own timer code.
This reduces a lot of code duplication.
