  Remove task-migration IPI.   It's been replaced
  by Ingo's migration threads.

  Define SI_DETHREAD.

Offer loopback driver and network block device support for HP Sim.

	Grr...  When loop in get_sb_bdev() had been switched from
global list of superblock to per-type one, we should have switched
from sb_entry(p) (aka. list_entry(p, struct super_block, s_list)) to
list_entry(p, struct super_block, s_instances).

	As it is, we end up with false negatives all the time.  I.e.
second mount from the same block device with the same type gices
a new superblock.  With obvious nasty results...

	This fixes that.

bdev filesystems switched.  Changes documented in Locking and porting.

The rest of nodev filesystems switched.

FS_LITTER filesystems (ramfs-like) switched to use of ->kill_sb().
FS_LITTER is gone.

New method - ->kill_sb().  It will eventually replace current
fs/super.c::shutdown_super() - i.e. it's called when fs driver
must shut the superblock down, remove it from all lists, etc.

Fix a few kNFSd problems.

1/ export svc_reserve which was introduced for NFS/TCP support.
    Without this we cannot load nfsd.o as a module
2/ the hash chain of clients was being changed (to put the found
   entry at the top of the list) while we only had a read-lock.
   This could corrupt the list and cause big problems.
   For now, just disable this code.  Might add a lock later...
3/ lockd was calling exp_getclient without getting a readlock
   on the export table first.
4/ Add Config.help entry for CONFIG_NFSD_TCP

If you create a shared mapping of a sparse file, dirty it
and then run msync, all the file's blocks are laid out
backwards.

This is because filemap_sync puts the lowest-index page at
mapping->dirty_pages.prev and the highest at mapping->dirty_pages.next.

I think that by walking the dirty pages list in ascending file
offset order as we instantiate their disk mappings we will generally
get better layout.

Fix rlimit on accounting file.

While looking at the bug fix for part 1 I coded up this patch
to change the BSD accounting code to use a spinlock instead
of the BKL.

Below is a patch to remove a small race in kernel/acct.c.

This patch replaces the current AMD IDE driver (by Andre Hedrick) by
mine. Myself I think my implementation is much cleaner, but I'll leave
upon others to judge that. My driver also additionally supports the
AMD-8111 IDE.

It's well tested, and I'd like to have this in the kernel instead of
what's there now.

is called once the inode is unlocked.

	Quick summary : this patch build on the first part to offer
two important new features :
		o Wireless Events
		o Wireless Cell Scanning
	Wireless Events are events generated by device, driver or the
wireless subsystem. It allows for example a device to notify user
space when it register to a new cell (roaming) or loose contact with
the current Access Points. Currently, the other defined events include
some configuration changes and packet drop due to excessive retries,
more may come in the future. All those events are useful for MobileIP,
V-Handoff and Ad-Hoc routing.
	Wireless Cell Scanning is a generic API to allow device/drive
to report Wireless Cells discovered (including ESSID, frequency and
QoS). This is similar to what is available in WindowsXP (except that
it's compliant to Wireless Extensions).

	This patch has been submitted for review on this list a couple
of time in January, has been on my web page since and used intensively
by other people. It was rediffed to 2.5.6. Driver patches have been
submitted to maintainers.

 - Fix oversight in replacement of sti() cli() pairs for data structure
   access protection.  This finally resolvs my problems with the 2.5.6
   kernel series.  Now I'm in fact quite puzzled how it was even possible
   for the system to get into the init stage without this fix..

 - Fix usage of CONFIG_BLK_DEV_IDE_MODULES instead of
   CONFIG_BLK_DEV_IDE_MODULE.

 - Make idescsi_init global for usage in systems without module support
   enabled.

 - Apply Pavels Macheks patch for suspend support.  Whatever some persons
   argue that it's not fully implemented, I think that we are in
   development series right now.  I don't buy the mock-up examples for
   problems with either outdated or broken hardware.  Micro Drives are
   for example expected to be drop in replacements for CF cards in
   digital cameras and I would rather expect them to be very tolerant
   about the driver in front of them.  And then the WB caches of IDE
   devices are not caches in the sense of a MESI cache, they are more
   like buffer caches and should therefore flush them self after s short
   period of inactivity without the application of any special flush
   command.  The upcoming explicit flushing commands in the ATA standard
   are about data integrity guarantees in high reliability systems, like
   DB servers for example, and not about simple cache validity.

 - Apply Vojtech Pavliks fix to the VIA host chip initialization code.

 - Add missing if-defs around PIO timing tables.

 - Fix max() min() related compile warnings in IDE-scsi.

No fixes for new problems which occured since today, just syncup.

 - Remove help text about suitable compiler versions, which is obsoleted
   by the overall kernel reality.

 - Remove traces of not progressing work in progress code for the
   CONFIG_BLK_DEV_ADMA option as well as the empty ide-adma.c file as
   well as CONFIG_BLK_DEV_IDEDMA_TCQ.

 - Remove redundant CONFIG_BLK_DEV_IDE != n check in ide/Config.in. Hugh,
   this is a tricky one...

 - Add EXPORT_SYMBOL(ide_fops) again, since it's used in ide-cd.c add a
   note there that this is actually possibly adding the same device twice
   to the devfs stuff.

 - Finally change the MAINTAINER entry. Just too many persons bogged me
   about it and it doesn't take me too much time apparently.

 - Apply sis.patch.20020304_1.

 - Don't call ide_release_dma twice in cleanup_ata, since ide_unregister
   is already calling it for us. Change prototype of ide_unregister to
   take a hwif as parameter and disable an ioctl for removing/scanning
   hwif from the list of handled interfaces. I see no reasons for having
   it and doing it is the fastest DOS attack on my home system I know
   about it. Contrary to the comments found here and there, hdparm
   doesn't use it. There are better hot plugging interfaces coming to the
   kernel right now anyway.

 - Wrap invalidate_drives in ide_unregister under the ide_lock instead of
   disabling and enabling interrupts during this operation. There are
   plenty of other places where the IDE drivers are enabling and
   disabling interrupts just to protect some data structures.

 - Don't call destroy_proc_ide_drives(hwif) for every single drive out
   there.This routine takes a hwif as a parameter.

 - Resync with the instable 2.5.6...

  Print values of type dma_addr_t by casting to unsigned long and using the %lx format.

changes.
