The patch below corrects multiple occurances of "the the"
typos across several files, both in source comments and KConfig files.
There is no actual code changed, only text. Note this only affects the /arch
directory, and I believe I could find many more elsewhere. :)Signed-off-by: Adrian Bunk

Now that devfs is removed, there's no longer any need to document how to
do this or that with devfs.This patch includes some improvements by Joe Perches.

Jesper Juhl reported that testing the software math-emulation by forcing
"no387" doesn't work on modern CPU's.The reason was two-fold:
- you also need to pass in "nofxsr" to make sure that we not only don't
touch the old i387 legacy hardware, it also needs to disable the
modern XMM/FXSR sequences
- "nofxsr" didn't actually clear the capability bits immediately,
leaving the early boot sequence still using FXSR until we got to
the identify_cpu() stage.This fixes the "nofxsr" flag to take effect immediately on the boot CPU.

check pr_debug() arguments
When DEBUG isn't defined pr_debug() is defined away as an empty macro. By
throwing away the arguments we allow completely incorrect code to build.Instead let's make it an empty inline which checks arguments and mark it so gcc
can check the format specification.This results in a seemingly insignificant code size increase. A x86-64

find_first_set doesn't find the least-significant bit on bigendian machines,

Once upon a time we needed to fixed limit to the number of md devices,
probably because we preallocated some array. This need no longer exists, but
we still have an arbitrary limit.So remove MAX_MD_DEVS and allow as many devices as we can fit into the 'minor'
part of a device number.Also remove some useless noise at init time (which reports MAX_MD_DEVS) and
remove MD_THREAD_NAME_MAX which hasn't been used for a while.Signed-off-by: Neil Brown

It is possible to request a 'check' of an md/raid array where the whole array
is read and consistancies are reported.This uses the same mechanisms as 'resync' and so reports in the kernel logs
that a resync is being started. This understandably confuses/worries people.Also the text in /proc/mdstat suggests a 'resync' is happen when it is just a
check.This patch changes those messages to be more specific about what is happening.

raid1, raid10 and multipath don't report their 'congested' status through
bdi_*_congested, but should.This patch adds the appropriate functions which just check the 'congested'
status of all active members (with appropriate locking).raid1 read_balance should be modified to prefer devices where
bdi_read_congested returns false. Then we could use the '&' branch rather
than the '|' branch. However that should would need some benchmarking first
to make sure it is actually a good idea.Signed-off-by: Neil Brown

Signed-off-by: Linus Torvalds -
Each backing_dev needs to be able to report whether it is congested, either by
modulating BDI_*_congested in ->state, or by defining a ->congested_fn.
md/raid did neither of these. This patch add a congested_fn which simply
checks all component devices to see if they are congested.Signed-off-by: Neil Brown

The error handling routines don't use proper locking, and so two concurrent
errors could trigger a problem.So:
- use test-and-set and test-and-clear to synchonise
the In_sync bits with the ->degraded count
- use the spinlock to protect updates to the
degraded count (could use an atomic_t but that
would be a bigger change in code, and isn't
really justified)
- remove un-necessary locking in raid5Signed-off-by: Neil Brown

Add a new sysfs interface that allows the bitmap of an array to be dirtied.
The interface is write-only, and is used as follows:echo "1000" > /sys/block/md2/md/bitmap
(dirty the bit for chunk 1000 [offset 0] in the in-memory and on-disk
bitmaps of array md2)echo "1000-2000" > /sys/block/md1/md/bitmap
(dirty the bits for chunks 1000-2000 in md1's bitmap)
This is useful, for example, in cluster environments where you may need to
combine two disjoint bitmaps into one (following a server failure, after a
secondary server has taken over the array). By combining the bitmaps on
the two servers, a full resync can be avoided (This was discussed on the
list back on March 18, 2005, "[PATCH 1/2] md bitmap bug fixes" thread).Signed-off-by: Neil Brown
