Here's a patch which fixes the deadlock Brad Fitzpatrick reported here:
http://lkml.org/lkml/2004/11/14/98

The meat of the problem is a locking order reversal between the XFS I/O
lock and the inode semaphore (i_sem).  When we mix a number of threads
doing both direct reads and writes, we hit an ABBA deadlock after a while
because direct-io.c is taking and dropping i_sem after the XFS read path
has already taken its I/O lock.  This is the wrong way around from XFS's
point of view, in particular its the opposite order to the XFS write path. 
So this patch changes the logic for direct reads in the DIO_OWN_LOCKING
case (i.e.  XFS-only case), but leaves things as is for the other two types
of locking.

Not real pretty, but fixes up the lock ordering and deadlock.

Oh, I have tested direct reads and writes on ext3 and block devices as
well, to ensure they still function correctly with the change (i.e.  they
don't regress, should be a no-op there) which covers the other locking
cases in __blockdev_direct_IO.

When cont_prepare_write() is padding out the "hole" with zeroed pages it
doesn't increase i_size at the same time.  If writeback comes in during the
execution of cont_prepare_write(), block_write_full_page() will think that
these pages are outside i_size and will just clean the page without writing
it.

Fix that up by using generic_commit_write(), which will advance i_size for
each page as it is dirtied.

raid10 performs resync by reading all blocks, comparing to look for The
requires re-tasking a bio that was used to read, so that it can be re-used
for write.  So a number of fields need to be reset.

The bi_bdev field was not being reset.  However when using on a partition
of a device, it gets changed by generic_make_request.

This patch simply resets bi_bdev to the correct value.

struct task_struct.comm is defined to be 16 chars, but
arch/x86_64/sys_ia32.c:sys32_ni_syscall() and sys32_vm86_warning() copy it
into a static 8 byte buffer, which will surely cause problems.  This patch
makes lastcomm[] the right size, and makes sure it can't be overrun.  Since
the code also goes to the effort of getting a local copy of current in "me",
we may as well use it for printing the message.

 o Remove the Baget platform due to lack of maintenance over several years.
   Some of the drivers remain and will be removed in a separate patch.
 o Remove the HP Laserjet platform.  No user reports ever and no patches from
   the original submitters made this port a neat hack - and a directory full

arch/arm/mach-sa1100/KConfig had options for USB client. The related code was removed early in 2.6. releases.
I think it is appropriate to remove the Config options for it itself, as they're void.

Alternate workaround for blocking usage of select() by UDP applications.
The problem is Linux optimizes the UDP receive checksum path so that checksum
validation is not performed until the application read. This is a performance win
but can cause applications that do select with blocking file descriptors to get false
positives if the received message has a checksum error.
There is a long running thread about this on LKML.

This patch makes these applications work, but keeps the one-pass performance gain
for those applications smart enough to use non-blocking file descriptors with
select/poll. There is still a possibility to get a false positive if application does
select on non-blocking fd then makes it blocking before doing the receive, but that
is unlikely.

Tested by injecting bad packets with SOCK_RAW.
