This was accidentally dropped before, but re-added now to completely mimic
behavior of the reboot notifier IDE used to have. 

  
The remove() method is generic for all drives, and set in ide_driver_t::gen_driver.
The call simply forwards the call to ide_driver_t::standby(). 

This obviates the need for IDE reboot notifier. The core iterates over all present
devices in device_shutdown() and unregisters each one. 

  
This adds
      struct device_driver    gen_driver;
  
to ide_driver_t, which is filled in with necessary fields when an ide
driver calls ide_register_driver(). That then registers the driver with
the driver model core. 
  
As a result, this gives us the following output in driverfs:
  
# tree -d /sys/bus/ide/drivers/
/sys/bus/ide/drivers/
|-- ide-cdrom
`-- ide-disk
  
The suspend/resume callbacks in ide-disk.c have been temporarily
disabled until the ide core implements generic methods which forward
the calls to the drive drivers. 

the netfilter ipt owner module still needs the following to compile

A second instance of lock had been inadvertently added to v_midi.h

Fix 3270 console reboot loop. Recognize 3270 control unit type 3174.
Fix tubfs kmallocs. Dynamically get 3270 input buffer. Get bootup colors
right on 3270 console

Pass the system call number in grp2 to strace instead of -ENOSYS.

Remove a duplicate memset. That is already done in alloc_disk.

Correct typo in the vmlinux.lds.S files.

Switch from work queues to tasklets in the 3215 and 3270 drivers.

Remove all tq_structs from s390 driver code.

Switch to @$(generate-asm-offsets.h) method to create the asm-offsets.h file,
fix signal dequeueing in the 31 bit emulation code and fix includes.

several notebook keyboards. Until we find a better solution how to detect
who are we talking to, we rely on the kernel command line. Use
atkbd_set=4 to gain access to the extra keys.

Switch over ATM code to initcalls and reorder the makefile so
that link order inside atm is the same.  I've also cleaned up
the makefile a bit while at it.

I didn't fix the existing compilation problems in the drivers (cli &
friends) and the broken le/be firmware selection for the fore200e cards
(kbuild breakage) though.

Noticed by Peter Chubb.

SCpnt->sense_buffer[0] has to _equal_ 0xf0 for the sense to be valid,
not vice versa.

Make 64-bit sector_t compulsory.  Accelerated testing...

From Peter Chubb

The bios geometry is almost useless, except for fdisk to try to write
an MSDOS partition table that is vaguely compatible with one written by
other operating systems.

If the size of disc will overflow a ten-bit cylinder number, then all
bets are off anyway.  So fake it by casting the true disc capacity to a
smaller type (than u64), so that we avoid 64-bit division on 32-bit
platforms.  If the disc is small enough that the number of cylinders is
correct, then this has no effect; otherwise, the number-of-cylinders we
report is bogus, but you can't use an MSDOS-format partition table on
such a drive anyway --- use the EFI GPT or the LDM partitioning, which
use 64-bit offsets internally.

From Peter Chubb

Get rid of need for GCC _udivdi3 and _umoddi3 helper functions
 - use sector_div more aggressively.

From Peter Chubb

(Yes I forgot something...  Without this patch, trying to use RAID
without CONFIG_LBD would fail.)

Fix md operation without CONFIG_LBD --- don't try to include __udivdi3
etc.

From Peter Chubb

Filesystem migration to possibly 64-bit sector_t:
 - bmap() now takes and returns a sector_t to allow filesystems
   (e.g., JFS, XFS) that are 64-bit clean to deal with large files
 - buffer handling now 64-bit clean

Enable 64-bit sector_t on IA32 and PPC.

kiobufs takes sector_t array, not array of long.
Fix blkmtd.c to deal in such an array.

Miscellaneous fixes for 64-bit sector_t.
 	 - missed printk formats
	 - ide_floppy_do_request had incorrect signature
	 - in blkmtd.c there was a pointer used to
	   manipulate an array to be used by kiobuf --
 	   it was unsigned long, needed to be sector_t

From Peter Chubb

Compaq Smart array sector_t cleanup: prepare for possible 64-bit sector_t

Clean up loop device to allow huge backing files.

MD transition to 64-bit sector_t.
 - Hold sizes and offsets as sector_t not int;
 - use 64-bit arithmetic if necessary to map block-in-raid to zone
   and block-in-zone

From Peter Chubb

printk changes: A sector_t can be either 64 or 32 bits, so cast it to a
printable type that is at least as large as 64-bits on all platforms
(i.e., cast to unsigned long long and use a %llu format)

Transition to 64-bit sector_t: fix isofs_get_blocks by converting the
(possibly 64-bit) arg to a long.

SCSI 64-bit sector_t cleanup: capacity now stored as sector_t; make
sure that the READ_CAPACITY command doesn't sign-extend its returned
value; avoid 64-bit division when printing size in MB.

Still to do:
 - 16-byte SCSI commands
 - Individual scsi drivers.

peter's code works for me, and the 40-odd people who download
the -mm patches.  Anton has tested it on ppc64 and I presume that
Peter has tested it on ia64.  I use gcc-2.91.66 and others use
later compilers.  I expect that any remaining problems will
mainly be caught by the compiler.  And compiler bugs can be
detected by turning off the option in config and seeing if things
get better.

From Peter Chubb

 - do_request() function takes sector_t not unsigned long as the
   block number to operate on.
 - Various casts to long where the underlying device can never get
   big enough to warrant a 64-bit sector offset.
 - Cast sector_t to unsigned long long when printing.

broken chipsets that don't support the LOOP command or report failure
on the TEST command. Hopefully this won't screw any old 386/486
systems without the AUX port.
