- remove md_ prefix from some calls that used to be
  defined in md_compatability.h

- remove "raid5_" prefix from some static functions,
  in line with recent changes to raid1.c

?? should cpu_has_mmx be moved to in processor.h ?

The current code hits the page cache for the block device
which requires memory allocation which can sometimes cause
a deadlock (if it blocks the raid5d thread).

This code takes the page that holds the superblock, and
passes it to submit_bh in a suitable bio wrapper.

I under-allocated the space that RPC needs for transmit on a UDP
socket.   We need lots of space to be allowed (though we may not use
much) so that a lack of un-commited transmit space will not cause new
requests to be blocked.

This fixes reiserfs compile warnings for a few bitops calls.

This patch5 changes reiserfs_new_inode to end the transaction on errors
(like -ENOSPC), so that it can call iput without deadlocking against the
journal.

Currently sys_read/sys_pread and sys_write/sys_pwrite basically contain
lots of duplication of the same checks/code.

This moves all that into vfs_read/vfs_write helpers that have the same
prototypes as the read/write file operations.  In addition I have
choosen to export these interfaces to module so people doing inkernel
file reading/writing can use these instead of duplicating the checks
(which is very likely to be done wrong).

A long time ago there was thread group code that at exit time tried to
reparent a task to another task in the thread group.  I discovered a major
race condition in this code, and submitted a patch that removed it.  This
patch was accepted in, I think, 2.4.12.  The code reappeared in 2.4.18 and
sometime in the 2.5 tree before 2.5.15, breaking applications that use
thread groups.

As part of chasing this down, I figured out a way to remove the race
condition while still preserving this behavior.  I've attached a patch
against 2.5.15 that fixes it.

This patch fixes the deliberate BUG_ON() on failed sgtable allocations.
I left that in because I was too lazy to fix it at the time...

Basically make scsi_init_io() return 0 on failure (like before) but this
time allow us to recover. scsi_init_io() will end_request on a fatal
condition. So now just mark the device/host as starved if needed, and
leave the request at the front of the queue for next service.

This patch fixes the behavior of vfatfs when the file name contains 0x05.

New driver for Micro Memory NVRAM module

This driver handles up to 16 PCI based NVRAM cards
from MicroMemory.
Each card appears like a block device, and can be partitioned
using any standard partitioning tool.  Upto 15 partitions are
supported.

This driver needs its own major device number and so allocates
one using register_blkdev.

Let's just get over with  this before queue handling will be targeted again...

- Implement suggestions by Russell King for improved portability and separation
   between PCI and non PCI host code.

- pdc202xxx updates from Thierry Vignaud.

- Tiny PIO fix from Tomita.

- Propagate the queue handling changes to pmac as well.

- Move set_transfer to ide-taskfile.c this is the only place where it's used
   and it can be made static there. Same applies to ide_ata66_check().

- Move ide_auto_reduce_xfer to ide.c.

- Make ide_cmd() local to the only place where it's used. Rename it to
   drive_cmd(). Don't pass drive_cmd_intr() as parameter.

- Remove ide_next command completion type. Nobody is using it.

- Move ide_do_drive_cmd to ide-taskfile. It's used there and in sub-drivers.
   Not in ide.c. The usage inside the device type drivers is entirely bogus
   inconsistent and so on...

- Kill bogus IRQ masking code. The kernel is supposed to handle this properly.
   We should not try to work against possible bugs in the overall irq handling
   code. Wow this is increasing the systems overall responsibility by a
   significant margin.

- Remove disfunctional pdcadma code. It is only misleading to the user.

- Streamline device detection reporting to always use ->slot_name.

- Apply 64 bit sector size fixes to the overall code.

- Push ->handler down to the struct ata_channel.

- Introduce channel group based locking instead of a single global lock for all
   operations. There are still some places where we have preserved the ide_lock.
   We can't lock for queues during device probe and we protect global data
   structures during device registration and unregistration in ide.c with it.

- Start replacement of serialized access to the registers of
   channels which share them with proper host chip driver specific locking.
   This affects the following host chip drivers:

   cmd640.c, rz1000, ... ?

   Seems some are setting the serialize flag just in case. So better let's do it
   gradually over time.

   Well, I still have to think whatever we really need to put channels sharing
   an IRQ line in the same locking group.

   From now on the sick concept of a hw group is gone now. We have full blown
   per channel request queues! Hopefully I will be able soon to get my hands on
   a dual Athlon machine to check how this all behaves on a multi SMP machine.

- Move the whole SUPPORT_VLB_SYNC stuff to the only place where it is used: the
   pdc4030 host chip driver.  Eliminate it from the global driver part.

- Eliminate pseudo portability macros from pdc4030. This is a host chip firmly
   based on VLB.

- Fix typo in pdc202xx driver.

- Fix locking order in ioctl.

- Fix wrong time_after usage introduced in 60. Maybe the fact I always get is
   wrong is related to the fact that I'm using the mouse with the left hand!?

- Apply arch-clean-2 by Bartlomiej Zolnierkiewicz.

- Don't disable interrupts during ide_wait_stat(). I see no reason too.

- Push flags down from hwgroup to the ata_chaannel structure.

- Apply small fixes from Franz Sirl to make AEC6280 working properly again.

This patch further cleans up and separates the code in an effort to
allow setting (a) a larger maximum real-time priority than default and
(b) a maximum kernel RT priority that is separate than the maximum
priority exported to user-space.

Special thanks to Intel for support and traces.

- Commented out the usb-ohci driver.  This is part of the migration away from
  this driver, to the ohci-hcd driver.
- Prevented the two UHCI_HCD drivers from both being compiled into the kernel
  at the same time.

This removes a compiler warning due to my previous patch.

fixed up the Config.in and Makefile merge due to there being 2 uhci-hcd drivers added at once.

After maturing for more than a month, I decided that it's enough...
So here's the patch for the HCD-version of usb-uhci, I called it
usb-uhci-hcd. For me, the usual devices work (TM).

Since the internals haven't changed much, I don't expect much difference to
usb-uhci in functionality and performance.

There is one major improvement: I've added a (preliminary) watchdog, that
regularly checks whether UHCI interrupts are coming through. If they are
"missing", ie. the HC halted without saying so, the HC is "re-animated" by a
real and clean restart, which is (internally) equivalent to a module-reload.
This is especially for VIA-chips which get comatose quite easily by babble
or other incorrect transfers.

The side effect is, of course, disconnects for all connected devices, but
they re-appear after a few seconds and were dead before anyway. So keyboard
and mouse work again, which is IMO a _very_ useful thing :-)

Another point: The watchdog (currently with moderate 8 interrupts/s) detects
IRQ-problems, so the misleading "device doesn't accept new device"-message
is replaced by an immediate error.

More comments and the separation into multiple files (I've taken ohci-hcd as
an example) should make the code more concise...

A few things are still on the todo-list and will come later:
- A few watchdog modifications (fewer interrupts, better diagnostics)
- Support for module "tune"-parameters for breadth/depth search, debug etc.
- interval support for ISO
- More SMP-tests
- maybe changes for reference counting when it is clear what survives :-)

Noticed by Eric Bowles.

Based on a patch from Georg Acher <georg@acher.org>

Woops, I sent the wrong version. There was one extra line that was
required.

This fixes up a couple of problems I came across while working on
uhci-hcd. There are a couple of places where shifts are used where they
shouldn't be and others where should be.

This cleans up a couple of cases and tidys it up.

The patch is relative to 2.4.19-pre8 and my other patches, but it's
alright to wait for 2.4.20. It should also be applied to 2.5.

So I finally hunkered down and got uhci-hcd working. I was surprised how
easy it was to make the modifications for hcd.c.

This patch has received a moderate amount of testing so far. I've played
with various devices and haven't had any problems. I won't claim it's
bug free yet and I'll continue doing more testing.

The patch includes a small change to hcd.c to not call free_config if
the HCD doesn't implement it.

There are some other messages that get printed such as:

hcd.c: usb_hcd_pci_remove 00:10.0, count != 1

but it appears from the code that this is just a soft warning that all
of the references to the bus aren't freed yet. This isn't a bug.

Differences from usb-uhci/usb-uhci-hcd:
- Cleaner code. uhci-hcd is based off of uhci, so it maintains the same
  look and feel as well as readability.
- Faster. The tests I've run so far show that uhci-hcd is faster in
  every case than usb-uhci-hcd
- It does not have the watchdog type feature for VIA chipsets. It's
  something that is definately possible to implement, but I'd like to
  find out what Windows does first.

Differences from uhci:
- Modified to use the hcd.c framework. This removed a significant amount
  of code and nesessitated lots of little changes.
- Big endian support. I haven't been able to test it on a big endian
  machine yet, but atleast 90+% of the work should be done. Once I get
  my PowerPC working again, I'll test this and submit any appropriate
  patches. This was the biggest functional change between uhci.c.
- No more urb->next processing. Completely ripped out.
- urb->interval support for Isochronous pipes.
- A couple of bug fixes for some problems I noticed while working on the
  code. These will be submitted for uhci.c in a seperate email.
