A buglet and a few adjustments.

This should be the last of tq_disk, at least the trivial ones. md still
has some queue_task references, I'll let Ingo/Neil clean those up.
suspend is still broken, it was broken before too though. I guess Pavel
will want to fix that.

Also, I've documented the plug functions.

 - PPC compilation fix by Paul Mackerras.

 - Various fixes by Bartek:

   fix ata_irq_enable() and ata_reset() for legacy ATA-1 devices

   in start_request() for REQ_DRIVE_ACB
   a) don't run ->prehandler() twice
   b) return ata_taskfile() value

 - Don't use ata_taskfiles cmd field for drive status reporting,
   we can now simply use drive->status instead.

 - Unify command type parser entries which could be unified due to the
   unification of corresponding interrupt handlers.

 - Eliminate reading parameter from ata_do_udma(). We have this information
   already in the rq. This allows us to merge several methods.

 - Rename XXX_udma to udma_setup, since we have finally settled up on this
   semantics.

 - Simplify tons of host chip code by removing wrapper functions.

 - Sanitize the handling of the ioctl's and fix a bug on the way in dealing with
   the WIN_SMART command where arguments where exchanged.

 - Finally sanitize ioctl further until it turned out that we could get rid of
   the special request type REQ_DRIVE_CMD entierly. We are now using
   consistently REQ_DRIVE_ACB.

   One hidden code path less again!

 - Realize the ide_end_drive_cmd can be on the REQ_DRIVE_ACB only for ioctl() to
   a disk. Eliminate it's usage from device type driver modules.

 - Remove command member from struct  hd_drive_task_hdr and place it in strcut
   ata_taskfile. It is not common between the normal register file and HOB.

   We will have to introduce some helper functions for particular command types.

 - Fix typo in sparc_v9 code, in ns87415, just introduced.

 - Eliminate unnecessary struct hd_drive_hob_hdr those are
   in reality precisely the same registers as usual.

 - Eliminate control_t, nowhere used type.

 - Unfold ide_init_drive_cmd() at the places where it's used. This makes obvious
   that REQ_DRIVE_CMD gets only used on the ioctl command path.

 - Move ide_fixstring() from ide.c to probe.c, since this is the place, where it's
   most used.

 - Remove GET_STAT() - it's not used any longer.

 - Remove last parameter of ide_error. Rename it to ata_error().

 - Don't use ide_fixstring in qd65xx.c host chip driver. The model name is
   already fixed in probe.c.

 - Invent ata_irq_enable() for the handling of the trice nIEN bit of the
   control register.  Consistently use ch->intrproc method every time we toggle
   this bit.  This simply wasn't the case before!

 - Disable interrupts on a previous channel only when we share them indeed.

 - Eliminate simple drive command handling function drive_cmd.

 - Simplify the ioctl handler. Move it to ioctl, since that's the only place
   where it's actually used.

as it isn't even all that big.

  David Mosberger added argument page to clear_user_page, but
apparently did not scan whole tree to find callers. Please apply.
It's the only such call in the non-arch specific portion of tree.

 - Get rid of SELECT_DRIVE macro. Start to move all direct hardware access
   functions in to one place.

 - Get rid of SELECT_MASK macro. Realize that the mask is always equal 0.
   Simplify the maskproc therefore.

 - Get rid of GET_STAT and OK_STAT macros as well.

 - hpt366 cleanups by Andrej Panin.

 - Artop driver update by Franz Sirl.

Here's my last and final patch to the maintainer of USB Scanner Driver.  Brian
Beattie <beattie@beattie-home.net> is now going to assume this role (thanks
Brian!).  Brian brings some kernel level programming so I'm sure he'll be able
to conttribute to this list w/o any problems.  I want to thank you all for your
support and help.  A couple of you sent some personal msgs regarding my
departure - thank you.

I just noticed a debug message will generate a needless warning

updated the kernel-api documentation USB files due to file reorg.

The patch below adds first round of AGP support for the Intel 460
chipset

This won't actually build at the moment, but I think you prefer to
merge things piecemeal, and this portion of the patch is almost
guaranteed to be safe (affects only ia64).

GCC3.1 apparently gets confused about uninitialized sections

Hi Linus,

Are you willing to change the interfaces of clear_user_page() and
copy_user_page() so that they can receive the relevant page pointer as
a separate argument?  I need this on ia64 to implement the lazy-cache
flushing scheme.

I believe PPC would also benefit from this.

	--david

On ia64 MP machines, we use the cycle counter register of each CPU to
obtain fine-grained time-stamps.  At boot-time, we synchronize the
counters as close as possible (similar to x86, though with a different
algorithm).  But even with this synchronization, there is still a
small (really: tiny) chance that a process bouncing from one CPU to
another could observe time going backwards.  To guard against this, I
maintain a global variable called "last_time_offset" which keeps track
of the largest time-interpolation value returned so far.  Most of this
is in platform-specific code (arch/ia64/kernel/time.c), but there are
a handful of places in platform-independent code where this variable
needs to be cleared to zero.  This is what the patch below does.  I
didn't put it inside CONFIG_IA64 because I think this can be useful
for other platforms, too.  I suppose I could put it inside CONFIG_SMP
though this would make the code uglier.  If you think it's OK, please
apply, otherwise, I'd appreciate your feedback.

This makes it possible to run the ia64 kernel both on platforms with the
legacy keyboard controller and those without (as is the case for the hp
zx1 platform, for example).  The new code is inside #ifdef CONFIG_IA64,
though it would probably be a good idea to enable it unconditionally.
The patch is by Alex Williamson.
