For reasons which escape me, blockdev_get_blocks() is returning -EIO if the
mapping request straddles the end of the disk.  This causes reads which
straddle end-of-disk to return -EIO.

Fix it up so that it correctly trims the returned result down to match the
size of the device, for both reads and writes.

If a write attempt is fully beyond end-of-device then return -EIO.  We never
get this far anyway, because generic_write_checks() will return -ENOSPC if all
of the write lies outside a blockdev's i_size.

I've written two document files, and packaged them as a patch.

Two things caught my eye while I was writing this up:

The header comments for CDROMREADRAW, CDROMREADMODE1, and CDROMREADMODE2
disagree with the actual source code.  The header comments imply that a
cdrom_read structure is used to pass data, but the source code actually
reads a cdrom_msf structure and then overwrites it with raw data.  I'm not
sure if there's a bug in the header comments, in the driver source, or I
misread something.

The CDROM_LOCKDOOR ioctl seems to lock/unlock all doors on all drives,
because it uses a global variable.

Stephen Rothwell noted a case where one CPU was sitting in userspace, one
in stop_machine() waiting for everyone to enter stopmachine().  This can
happen if migration occurs at exactly the wrong time with more than 2 CPUS.
 Say we have 4 CPUS:

1) stop_machine() on CPU 0creates stopmachine() threads for CPUS 1, 2
   and 3, and yields waiting for them to migrate to their CPUs and
   ack.

2) stopmachine(2) gets rebalanced (probably on exec) to CPU 1.

3) stopmachine(2) calls set_cpus_allowed on CPU 1, sleeps awaiting
   migration thread.

4) stopmachine(1) calls set_cpus_allowed on CPU 0, moves onto CPU1 and
   starts spinning.

Now the migration thread never runs, and we deadlock.  The simplest
solution is for stopmachine() to yield until they are all in place.

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.
