A few cases of list_del(x) + INIT_LIST_HEAD(x) crept in recently which
can be replaced with list_del_init(x).

 - Work a bit on the automatic CRC error recovery handling. System still hangs.
   But one thing for sure - we don't have to use any specialized irq handler for
   it.

 - Since ioctl don't any longer submit requests to the queue without
   rq->special set, we can safely remove args_error handling from
   start_request.

 - Make REQ_SPECIAL usage in ide-floppy obvious.

 - Use REQ_SPECIAL everywhere instead of REQ_DRIVE_ACB. This is actually a bit
   dangerous but should work as far as I can see.

 - Unfold the now not REQ_SPECIAL specific dequeing part of ide_end_drive_cmd().
   Turns out that we can thereafter remove the calls to ide_end_drice_cmd() at
   places where the request type isn't REQ_SPECIAL all any longer. (tcq.c)


 - After the above operation it turns out that there are just two places where
   ide_end_drive_cmd remains, namely: ata_error, task_no_data_intr
   drive_cmd_intr.

   We can avoid it by changing the logics in ata_error a slightly.

   So now just to cases remain where ide_end_drive_cmd remains used:
   drive_cmd_intr and task_no_data_intr.

 - Now looking  a bit closer we can realize that drive_cmd_intr and
   task_no_data_intr can be easly merged together, since the usage of
   task_no_data_intr implied taskfile.sector_number == 0.

 - Use one single ata_special_intr function for the handling of interrupts
   submitted through ide_raw_cmd.

 - Move the remaining artefacts of ide_end_drive_cmd directly to
   ata_special_intr. Oh we don't need to check for REQ_SPECIAL any longer there,
   since the context is already known.

 - Set the ata_special_intr handler and command type directly inside
   ide_raw_taskfile to save code.

Same thing as patch #1165/1 but for 2.5.x

The kernel expects these to return values in unsigned long types.

- remove LAST_DESC in favour of passing the array size to iotable_init
- replace domain and permission bits/cache attributes with a generic
  "type", which can be easily converted to the required domain and
  permission bits/cache attributes at run time.  It also removes the
  possibility for getting such things wrong and (accidentally)
  allowing all user space to fiddle with devices directly.

This patch removes fsuser().  Now both suser() and fsuser() are gone and
all permission checks use an appropriate capable() call.

Attached patch replaces the lone remaining suser() call with capable()
and then removes suser() itself in a triumphant celebration of the glory
of capable().  Or something. ;-)

Small cleanup of capable() and some comments, too.

 - Simplify ide_cmd_type_parse by removing the handling of commands which we
   never use.

 - Realize that pre_task_out_intr and pre_task_mulout_intr are semanticaly
   identical. Use only pre_task_out_intr(). This allowed us to
   eliminate the prehandler altogether.

 - Updated fix for misconfigured host chips by Vojtech Pavlik.

 - Be more permissive about ioctl handling to allow device type drivers to do
   they own checks.

 - ali14xx cleanups by Andrej Panin.

 - Unfold usage ide_cmd_type_parser in tcq.c code. This makes this operation
   local to ide-disk.c. Move it as well as the interrupt handlers used only for
   the handling of disk requests there too.

 - Guard against calling handler before the drive is ready for it in
   ata_taskfile()! Well this bug was there before, but right now we inform
   about it.

 - Unfold ide_cmd_type_praser in ide-disk.c. Merge the remaining bits of it with
   get_command. Well it's no more.

 - Move recal_intr to ide.c - the only place where it's used.

This doesn't change the "mechanics" of the code but it makes it a lot more
"obvious" what's going on.

2.5.20 seems to be incapable of executing binaries in a ramdisk-based
root filesystem.  The ramdisk in question is an ext2fs, with a 1K
block size loaded via the compressed ramdisk loader in do_mounts().

It appears that, in the case of a 1K block sized filesystem, we attempt
to read two 512-byte sectors into a BIO vector.  The first one is copied
into the first 512 bytes.  The second sector, however, is copied over
the first 512 bytes.  Obviously not what we really want.

Rev. 2, slightly cleaned up:

Noted by Alexey Vyskubov

- Make sure proper pci id is passed to probe()
- make sure pci_dev->driver is set and reset on driver registration/unregistration
- call remove_driver to force unload of driver on unregistration

driver_unbind was called when drv->refcount == 0.
It would call driver_for_each_dev to do the unbinding
The first thing that would do was get_device, which...
BUG()'d if drv->refcount == 0. 
Duh. 

- make sure drv->devices is initialized on registration (from Peter Osterlund)
- add remove_driver for forcing removal of driver

There was a potential race with the module unload code. When a pci driver was unloaded, it would call pci_unregister_driver, which would simply call put_driver.
If the driver's refcount wasn't 0, it wouldn't unbind it from devices, but the module unload would still continue. 
If something tried to access the driver later (since everyone thinks its still there), Bad Things would happen. 
This fixes it until there can be tighter integration between the device model and module unload code.

Here's followup patch that makes it work. Notice freeze_processes() --
if you don't do that you risk data corruption.

This cleans up swsusp in 2.5.20. Killed sysrq-D support (it is too
much trouble to support suspending from interrupt), kill unused
define, fix compile-time warnings (thanks to Adam).

I created arch/i386/suspend.c not to clash with ACPI people so much in
future. (More stuff is going to move into it in the future, to clean
up functions that really do not belong to the headers.)

This patch merges in all the currently outstanding bluesmoke bits from
2.5-dj to 2.5.20, it also has the pleasant side effect of fixing the
compilation. Test compiled with and without MCE.

  Here's that patch again (MIME this time, so tabs don't get
  lost by my silly gui mailer); applies cleanly against against 2.4.19-pre8.
  Nobody commented on it last time I posted it, and it does
  make compiling gcc easier, so I guess that makes it trivial patch
  monkey fodder.  Or am I making a silly mistake?

  Most /proc/slabinfo cache_names are in the format:
  cache_name.  There are a couple with spaces in the
  name, which is inconsistent and requires a special case
  when scripting.

  Changes "fasync cache" and "file lock cache" to have
  the usual underscore.

  inactive_list and active_list are global, yet they are repeatedly
  initialized using INIT_LIST_HEAD() in free_area_init_core(). This
  patch is originally due to Christoph Hellwig, and by some reports
  has been implementated before in 2.4-based trees by Andrea Arcangeli.

  The memlist_* macros serve as nothing but an insulation layer from the
  Linux-native generic list operations. This patch removes them in favor
  of using generic list operations directly.

  This comment, describing how to optimize for gcc-2.2.2, is so outdated
  it should be removed. It's also quite doubtful it should ever have been
  placed in this file at all (perhaps something under Documentation/ ?).
  This patch removes it.

  memclass is too large to be a #define; it overflows 80 columns and does
  not make use of facilities available only to macros.

  This patch convert memclass() to be an inline function.

  I found this one while trying to straighten out bootstrap ordering
  issues elsewhere.

  There appears to be a duplicate declaration of rq in sched_init().
  This removes the nested declaration and otherwise leaves things alone.

  The comment describing the usage of zone_table[] assumes the existence
  of an unsigned char page->zone field from the original implementation
  of page->zone size reduction. This patch corrects the comment to
  accurately describe the lookup mechanism used by page_zone() and also
  to mention explicitly the sole user of the table, page_zone().

Playing with arch stuff does this to you.

Rusty Russell <rusty@rustcorp.com.au>: Oh, I feel so violated...:
  <sniff>

  This patch against 2.5.19 gets rid of some bogus casts in ide-cd.c
  In my opinion the casts as is are bugs waiting to happen.

  I found that 'max' pointer is not updated in proc_dointvec_minmax()
  and proc_doulongvec_minmax(), when I write smaller values than min to
  /proc/sys entry (and val<*min++ check becomes true.)
  This may lead to min/max checking of values with bogus maximum.

  Unrelated to my first dcache patch, this is something more crucial
  and should be applied first.

  fs/dcache.c:
   - handle d_alloc() returning NULL.

  Attached is a really trivial patch that changes an "unknown" PCI_DEVICE_ID
  0x3112 to PCI_DEVICE_ID_VIA_8361 in drivers/pci/quirks.c .

  It applies cleanly to 2.5.18 and 2.4.19-pre8.

  There is more of this janitorial work to come (eg General setup). I'm just
  piecemealing it

  [ Made applicable with -p1 by Rusty ]

  nlma fixes a call to netlink_broadcast with GFP_KERNEL ( passed to
  skb_clone ) while we are in_interrupt() ( catched by a BUG() in
  slab.c:1109 ).

  Missing include of asm_io.h in mm_bootmem.c:
  Submitted this trivial patch on May 14, but nothing has happened yet.
  Perhaps better chance if you took care of it.

  It's needed by phys_to_virt() but it happens to work on i386 etc.
  since dma.h includes io.h for that arch.

The following has been vetted with davem w.r.t. the change to
KM_SKB_DATA. Apologies for the bug...

include/asm-*/kmap_types.h:
   Replace the unused km_type slot KM_SKB_DATA with
   KM_SKB_SUNRPC_DATA.

net/sunrpc/xdr.c:
   Replace the use of KM_USER0 with KM_SKB_SUNRPC_DATA for copying
   data from an skb into the page cache when in the sk->data_ready()
   callback.

Fix queue plug locking.

This fixes two shift warnings on 64 bit archs.
