- Initialize the mftbmp address space properly now that there are more
fields in the struct address_space. This was leading to hangs and
oopses on umount since 2.5.12 because of changes to other parts of
the kernel. We probably want a kernel generic init_address_space()
function...
- Drop BKL from ntfs_readdir() after consultation with Al Viro. The
only caller of ->readdir() is vfs_readdir() which holds i_sem during
the call, and i_sem is sufficient protection against changes in the
directory inode (including ->i_size).
- Use generic_file_llseek() for directories (as opposed to
default_llseek()) as this downs i_sem instead of the BKL which is
what we now need for exclusion against ->f_pos changes considering we
no longer take the BKL in ntfs_readdir().

Here is the patch to replace mk_pte_phys() with pfn_pte() and so creates
the counterpart to pte_pfn().

This patch removes VALID_PAGE(), as the test was always too late for
discontinous memory configuration. It is replaced with pfn_valid()/
virt_addr_valid(), which are used to test the original input value.
Other helper functions:
pte_pfn() - extract the page number from a pte
pfn_to_page()/page_to_pfn() - convert a page number to/from a page struct

PRD_SEGMENTS was a leftover from struct ata_request an its per-command
sg tables.

 - 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 - Nuke some vastly outdated comments.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:

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 .

- 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

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.
