- Synchronize with Jens.  Applying tons of janitorian stuff to his TCQ
   code.  Making functions static where appropriate and so on...
   Marking the config entry for it experimental and so on.  His
   changelog:

	2.5.13 now has the generic tag support that I wrote included,
	here's an IDE TCQ that uses that.  Changes since the version
	posted for 2.5.12:

	Fix the ide_tcq_invalidate_queue() WIN_NOP usage needed to clear
	the internal queue on errors.  It was disabled in the last
	version due to the ata_request changes, it should work now.

	Remove Promise tcq disable check, it works just fine on Promise
	as long as we handle the two-drives-with-tcq case like we
	currently do.

 - Fix wrong usage of time_after in ide.c. This should cure the drive seek
   timeout problems some people where expierencing. This was clarified to me by
   Bartek, who apparently checked whatever the actual code is consistent with
   the comments in front of it. Thank you Bartlomiej Zolnierkiewicz.

   I think now that we should have time_past(xxx) in <linux/timer.h>.

 - Fix hpt34x.c compilation.

 - Minor improvements in ide-pci and some cleanups in ide-probe.c

 - Nuke some vastly outdated comments.

D'oh.  Missing commas...

Needed both in 2.4 and 2.5

Nothing serious. Whoever it was that did that global replace missed a
spot is all...

The following patch fixes this, and also fixes the similar problem in
scsi_debug.c:

Upgrade is imperative!

Minor cleanups to a scsi fibre channel HBA driver that was broken by the
introduction of SCSI_REPORT_LUNS to scsi.h in a patch that went into
2.5.11 .

Documentation enhancement from Kai.Makisara@metla.fi.

Fix oopses on ISA scsi adapters.

- The balance_dirty_pages() logic is simply wrong.  It goes:

	if (value > threshold)
		go_and_write(value - threshold);

  which is just fine for a single process writing data.  But
  for many processes, they *all* go and bring things back into
  balance, and too much data gets written out.

- The

	go_and_write(this much)

  logic is inoperative, because I turned off the ->writeback_mapping()
  function in ext2.  So a call to writeback_unlocked_inodes(this_much)
  doesn't actually decrement and test *this_much.  It will walk every
  inode, all the time.  Silly.

So quickly fixing the above things, the amount of dirty+writeback
memory in the machine nicely stabilises at 500 megabytes across
the run.

The new consistency checks in buffer.c are complaining about
block_symlink's ->readpage against an already uptodate
page.

- Fix compilation of piix.c

- Remove the PADAM_ prefix from sleep hwgroup member.

- Fix Pacific Digital host chip driver API.

- Fix Tekram host chip driver API.

- Fold hwif_unregister() directly in to channel code.

Add support for request tagging of the block queue.

This patch makes usbvideo_register take a usb_device_id argument which it
can then pass to usb_register via the struct usb_device. Currently it passes
NULL.

This patch makes usbvideo.c use the correct value of USBVIDEO_NUMFRAMES.
A few places in the code assumed it was 2. This patch was tested with
USBVIDEO_NUMFRAMES = 2,3,4,8,11,32

cleaned up checking the return value of usb_register_dev()

added Black Box OEM device ids to the io_edgeport driver.

USB pl2303 driver

This is a patch which avoids resetting the termios settings to default
values (9600 Baud etc.) in each call to pl2303_open (). It does this
only on the first call to pl2303_set_termios. After that it sets the
termios to the last stored values.

 This way commands like
 stty -F /dev/ttyUSB0 115200
 work the same way as with other serial ttys.

USB printer bugfix

looking through printer.c in preparation for shifting devfs
support to usbcore I noticed that printer advertises a device
through devfs before it can be opened.
As devfs, or more precisely devfsd can be used to trigger actions
this matters and is wrong.

- Fix macro varargs usage, you need to specify a variable name
before the triple dot or else most current compilers complain.
See include/linux/ext2_fs.h:ext2_debug for another example where
it is done correctly.

- Fix bug in strsep/strchr changes, dereference *this_char
not *value at top of while loop.  This matches how the same
code in fs/autofs4/inode.c looks right now.
Withtout this autofs loading causes an OOPS as the first
time through the loop *value is dereferencing a NULL pointer.

Allocate and free the avmcard structure using a shared function.

Remove unnecessary wrappers around irq handlers.

Interrupt handlers won't be reentered anyway.

Fix some set_bit() warnings.

The real rule is not "block size is at most 32Kb", it's "block size is
at most 8 times the fragment size".

(originally caught by Paul Larson <plars@austin.ibm.com>)

	Patch fixes a couple of idiotic bugs in notify_change() (my
fault).  Unary operations have higher priority than binary ones, so
if (!valid & ATTR_MODE) doesn't do the right thing.  I plead temporary
braindamage...

The below patch on 2.5.12 takes the 'dbench 32' throughput on a
1024 megabyte machine from 35 megs/sec up to 125 megs/sec.
That's on the second run.  The first run is much slower because
the ext2 bitmaps aren't in cache.

Presumably, s/60/80/ will take it even higher.
