This fixes a problem where MSDOS fs's ignore their 'check' mount option.

Original fix from Andi Kleen

Originally by Anton Altaparmakov.
I think Anton is going to submit his rewritten NTFS soon making this null and void,
but in the interim, it fixes a known problem with NTFS and large allocations.

The preempt_count debug check that went into 2.5.8-pre1 already caught a
simple case in kjournald.  Specifically, kjournald does not drop the BKL
when it exits as it knows schedule will do so for it.

For the sake of clarity and exiting with a preempt_count of zero, the
attached patch explicitly calls unlock_kernel when kjournald is exiting.

Adding proper print level qualifier to the printk calls.

Adding missing pci write flush to the procedure e100_exec_cmd

The patch separates max busy wait constants making in max of 100 usec for
wait scb and max of 50 usec for wait cus idle. These constants found
sufficient using heavy traffic tests.

Again, we don't need to sync indirects as we dirty them because
we run a commit if IS_SYNC(inode) prior to returning to the
caller of write(2).

Writing a 10 meg file in 0.1 meg chunks is sped up by, err,
a factor of fifty.  That's a best case.

At present, when mounted synchronously or with `chattr +S' in effect,
ext2 syncs the indirect blocks for every new block when extending a
file.

This is not necessary, because a sync is performed on the way out of
generic_file_write().  This will pick up all necessary data from
inode->i_dirty_buffers and inode->i_dirty_data_buffers, and is
sufficient.

The patch removes all the syncing of indirect blocks.

On a non-write-caching scsi disk, an untar of the util-linux tarball
runs three times faster.  Writing a 100 megabyte file in one megabyte
chunks speeds up ten times.

The patch also removes the intermediate indirect block syncing on the
truncate() path.  Instead, we sync the indirects at a single place, via
inode->i_dirty_buffers.  This not only means that the writes (may)
cluster better.  It means that we perform much, much less actual I/O
during truncate, because most or all of the indirects will no longer be
needed for the file, and will be invalidated.

fsync() and msync() still work correctly.  One side effect of this
patch is that VM-initiated writepage() against a file hole will no
longer block on writeout of indirect blocks.  This is good.

problem.

In ext3_new_block() we increment i_blocks early, so the
quota operation can be performed outside lock_super().
But if the block allocation ends up failing, we forget to
undo the allocation.  

This is not a serious bug, and probably does not warrant
an upgrade for production machines.  Its effects are:

1) errors are generated from e2fsck and

2) users could appear to be over quota when they really aren't.

The patch undoes the accounting operation if the allocation
ends up failing.

z_{read,write}[bwl] routines from 2.4.x.

o [CRITICA] Fix race condition between disconnect and the rest
o [CRITICA] Force synchronous unlink of URBs in disconnect
o [CRITICA] Cleanup instance if disconnect before close
        <Following patch from Martin Diehl>
o [CRITICA] Call usb_submit_urb() with GPF_ATOMIC

o [FEATURE] Propagate mode of discovery to higher protocols
o [CORRECT] Disable passive discovery in ircomm and irlan
  Prevent client and server to simultaneously connect to each other
o [CORRECT] Force expiry of discovery log on LAP disconnect

if socket is not connected, don't hangup, to allow passive operation

o [CORRECT] Handle signals while IrSock is blocked on Tx
o [CORRECT] Fix race condition in LAP when receiving with pf bit
o [CRITICA] Prevent queuing Tx data before IrComm is ready
o [FEATURE] Warn user of common misuse of IrLPT

* make sure to stop chip before enabling interrupt via request_irq

* use Zorro-specific z_{read,write}[bwl] routines
* remove superfluous include

* add support for LSI 10/100 phy
* other minor cleanups

* Moved to 2.4.14, ppopov@mvista.com.  Modified driver to add
proper gt96100A support.
* Moved eth port 0 to irq 3 (mapped to GT_SERINT0 on EV96100A)
in order for both ports to work. Also cleaned up boot
option support (mac address string parsing), fleshed out
gt96100_cleanup_module(), and other general code cleanups
