This patch makes nfsd_open use init_private_file to initilize
the file pointer the caller had allocated on stack.  In addition
a number of small cleanups:

 - format comments to be readable on 80char ANSI terminal
 - don't fop_get (and fop_put in nfsd_close), out file already
   is a reference to the inode so they can't go away.
 - don't decrement f_count on failure - it won't be checked anyway
 - don't check for filp->f_op n nfsd_close, it can't be NULL

Separate checks for !FS_REQUIRES_DEV and missing fsid option
and missing export operations, second check for missing export
operations and a small cleanup as side effect.

With this patch raid5 works.  There is still some more
work to though.

- uses bio instead of buffer_head
- stripe cache is now a fixed size.
   If read requests are smaller, we read the whole block anyway
   If write reqeusts are smaller, we pre-read.
- stripe_head is now variable sized with an array of structures at
  the end.  We allocate extra space depending on how many devices
  are in the array.
  stripe_head has it's very own slab cache.
- store and use bdev for each device in array

by-passing the cache for reads is currently disabled.  I need to
think through the implications (and implementation) of allowing
large bion that are larger than the stripe cache to go directly
to the device (if it isn't failed of-course).

- 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 :-)
