Big bits first, I'll redo the smaller bits tomorrow after some sleep.
Same as last time, rediffed against pre5

There are a couple of errors in the DMA changes to the
aha1542.c driver that appeared in 2.5.4pre3:

- a typo (BUF vs BUS)
- a macro handed a page instead of a scatterlist
- printk format length mismatch

Paul.

Make dentry and ->i_sem manipulations in driverfs explicit.  Something
is seriously rotten there and real fixes will take non-trivial work
(e.g, I suspect that we actually ought to kill driverfs_rename() - at
least cross-directory one for regular files, maybe completely).  This
patch simply cleans the ground. 

	Mostly cosmetical cleanup - sane variable names, etc.
That's pretty much it for balloc.c cleanups - stuff after that
will be about decent threading.

in ext2_new_block() inode->i_sb can't be NULL.  Dead code removed.

merged returns in ext2_new_block()

in ext2_new_block() added a local variable (sbi) for sb->u.ext2_sb;
users converted. 

calculation of prealloc_goal moved into beginning of function. 

new local variable (block).  Initialized to 0, set to the number of
allocated block only when we are known to be successful. 
ext2_new_block() returns the value of 'block' now.  As the result, out:
is gone - it's identical to out_unlock now. 

check for block being chosen past the end of disk had been moved up No
sense to check that after we had done the preallocations... 

quota allocation taken into the beginning of ext2_new_block().  we put
the number of blocks we'd reserved into dq_alloc and then decrement it
each time old code would do DQUOT_ALLOC/increment when it would do
DQUOT_FREE.  On the exit we release dq_alloc blocks I.e.  all
allocations are pushed into the beginning and all freeing - to the end. 

now that we had moved the last possible point of failure up, we can do
the same with assignment of final result to block. 

code that does allocation within a group had been taken out into a
helper - grab_block(map, size, goal). 

decrementing fs-wide free blocks count moved into the beginning of
function.  We try to reserve up to dq_alloc blocks - amount we _can_
grab is limited by the actual free space and root-reserved percentage. 
That logics had been taken into a helper - reserve_blocks(sb, amount). 
Number of blocks we had managed to reserve is put into es_alloc.  When
we actually grab a block, es_alloc is decremented.  Upon the exit we
release the leftovers.  Old code didn't honor 'reserved for root' limit
when doing prealloc - now that had been fixed. 

EXT2_BLOCKS_PER_GROUP(sb) put into a local variable (group_size)

similar "reserve and release leftovers in the end" scheme for group
(i.e.  we try to reserve as much as we want in the group, then count how
much had been used up and release the leftovers in the end). 

cleaned up the preallocation loop. 

minor cleanup: update 'freed' only after we finish with group

in ext2_free_blocks() inode->i_sb can't be NULL; dead code removed.

new helper - group_release_blocks(desc, bh, count); updates free blocks
count for given group ext2_free_blocks now counts the blocks freed in
group and updates the per-group free blocks count at once. 

we postpone releasing the quota until the end of ext2_free_blocks() and
do that at once. 

new helper function - release_blocks(sb, n); in ext2_free_blocks() we
count the blocks we'd freed and update the fs-wide count of free blocks
in the end - just before unlocking superblock.  instead of doing that
step at a time.

You are right, it did.  I removed all the sched.h dependencies and this
reduced the size of the patch greatly.  I now use current_thread_info()
and none of the header or include hackery from before.  I've tested this
with and without preemption enabled with success.

I appreciate your help with this.

Again, this is a minimal i386-only patch.  I have other arches,
documentation, etc.  Patch against 2.5.4-pre5.  Enjoy,

Fix lost argument to "connect()"

struct device has no ->sysdata
and ->device should be ->dev
 

exp_procfs_exports() switched to seq_..., missing lock added.

all exports for given client are put on the cyclic list
(->cl_list/->ex_list).  Code cleaned up.

exports hash switched to use of struct list_head, code cleaned up.

Change to use the new include/linux/zconf.h

Additional descriptions that got lost along the way somewhere.
Also updates some extra IDE options that shared the same fate.

unneeded these days..

- Reorder mainmenu items so CONFIG_EXPERIMENTAL is at the top again.
- Various updates from 2.4

2.4/2.5 kernels suffer from an infinitely long hang when a serial tty device
is closed, and there are characters waiting to be sent.  The hang occurs in
tty_wait_until_sent.

There is a timeout 'closing_wait' which defines how long to wait for the TX
buffers to empty; the problem is that the serial layer totally ignores it.
It is stored in two structures, 'info' and 'state'.  It is initialised in
the 'state' structure, but used from the 'info' structure.

It turns out that 'hub6' was also missing.

I'm not currently clear what the expected behaviour should be when the
timeout is changed via setserial, and others have the port open - I've
opted to preserve the timeout until all users close the port.  It's
trivial to change this behaviour though.

Mostly from 2.4.17 / 18pre.
- Code cleanup
- Fix suspend/resume on several chipsets
- Add support for i820.

Make spinlocks etc use subsections of their parent sections instead of
an ELF section of their own - needed for newer binutils when the parent
sector is removed. 

Newer Athlons have means of checking if they are SMP capable or not.
This code adds checks that printk a warning on systems not intended
for SMP, and set the taint flag that modutils is already aware of.
The taint code is also improved to use defines instead of magic numbers.

swap_info_struct became pretty much superfluous.  As we are minimizing
kdev_t usage anyway, I took the opportunity to remove swap_device
member, and replace the remaining usages with SWP_BLOCKDEV bit flag.

Adding SWP_BLOCKDEV in turn motivated a small cleanup of the
SWP_xxx bit flags and their usage.

Patch has been in light testing for a couple weeks, and
has been glanced at by Al.  "looks sane"
