cpqarray.c switched to per-disk gendisks

Big One.  Flushing/rereading partition tables is taken from
->revalidate() for partitioned devices; now it's done in the
caller (check_disk_change()).  BLKRRPART handling also moved
out of drivers - they are still allowed to override it (DAC960
and i2o are the only remaining ones), but common case is handled
in fs/block_dev.c.

Note: we are still only shifting stuff - bd_sem deadlocks in
check_disk_change() are still there.  However, now we have all
relevant code outside of drivers and that will allow to fix the
thing (see next patches).

->attach() for ide subdrivers explicitly calls register_disk()
instead of ata_revalidate() now; revalidate_drives() is gone -
it's not needed anymore (we _know_ that we'll read partition
table as soon as driver claims the drive; no need to mess with
bogus rereading).

->major_name for per-disk gendisks set to full name - i.e.
IDE gendisks have "hda", "hdb", etc. instead of "hd".
As the result, we kill a lot of crap in check.c::disk_name().
In particular, now we can afford ->minor_shift set to 0
for ide-cd (disk_name() was the only obstacle)

check_disk_change() converted to passing struct block_device.

Old variant is still needed for a couple of places; wrapper
is provided (__check_disk_change(kdev)).  do_open() logics
with setting ->bd_op sanitized - now we do that before calling
->open().

fix for embarrassing braino in /proc/partitions - size in kilobytes
is _half_ the size in secotrs, not twice that size...

Present both in 2.4 and 2.5 ;-/

we are starting to split gendisks - now we can do that.  Done for
ide, sd, pd, hd and mfm

It's in transit - what we are aiming at is getting ->nr_real to 1 for
all gendisks.  Once that will be done we will be able to simplify a lot
stuff and remove ad-hackery.  First thing that will happen after that
is death of ->nr_real, obviouslye.  Then we
	(a) will merge ->major and ->first_minor into ->dev
	(b) strip one level of indirection from  ->driverfs_dev_arr, ->de_arr
and ->flags - they turn into single-element arrays and we will simply pull
the (only) element into struct gendisk.  Kills a lot of ad-hackery in splitup
code (fewer things to allocate).
	(c) replace ->major_name with ->disk_name; kills most of the crap in
disk_name(9) - it only has to care about adding partition number to the name.

now that gendisks don't have shared stuff (we used to set blk_size[]
from ->sizes) we can start splitting them into per-disk ones.

Step 1:
  we introduce a new field - ->first_minor (to be merged with ->major
  into dev_t of entire disk once all gendisks are split).  All arrays
  are assumed to start at that minor (i.e.  gd->part[minor] got replaced
  with gd->part[minor - gd->first_minor], etc.).  get_gendisk() is
  taught to pick the right gendisk if there are several with the same
  major.

kills use of blk_size[] for partitioned devices, removes ->sizes from
struct gendisk.

This patch corrects a comment on the 8139cp ethernet driver.

This removes the TLS clear operation.  I've left the flags mask and the
writable flag just so that we have the option to introduce extensions
without breaking the ABI.

this is a small patch for boardergo.c linux driver for isdn HYSDN cards to
    1) remove call to check_region using request_region instead
    2) check the status of call to request_region
    3) release allocated region resource in case of error.

I don't have this hardware so compilation checked only.

[ Typo fix, makes sense, please apply ]

Symbols CONFIG_HISAX_ENTERNOW_PCI and CONFIG_HISAX_AMD7930 depend on
CONFIG_EXPERIMENTAL but do not say so in their banners.

Symbol CONFIG_PPPOATM doesn't depend on CONFIG_EXPERIMENTAL but claims
to in its banner.

Somebody noticed on #kernelnewbies. In the error path, so this is
silly cleanup work...

Some CML1 rule contributors seem to think that the "bool" statement
takes a third argument which is the default value.  It doesn't.

I am not sure if you are the actual maintainer for this, but your name
adorns the source :
  2.5.28 introduced video mode 1400x1050 twice into drivers/video/modedb.c
Both instances use indentical timings, so I guess it's a mistake.

Symbol CONFIG_EXT3_FS doesn't depend on CONFIG_EXPERIMENTAL but claims
to in its banner.

Quick fix for:

this is a small patch for baycom_ser_hdx.c  -- baycom ser12 halfduplex radio modem driver to
    1) remove call to check_region using request_region instead
    2) check the status of call to request_region
    3) release allocated region resource in case of error.

They are harmless mostly and can happen in normal use. (from -rh)

Silence bitop on non-long argument warnings.

To make spinlock debugging work with -funsigned-char the i386 version
of spin_is_locked() needs to cast to signed char explicitly instead of
just char.  XFS needed -funsigned-char (and currently still has it),
but it doesn't evert hurt.

Here are patches for designated initializers in kernel/*.

(Included in 2.4)

Silence bitop on non-long argument warnings.

[ Not just silence warnings, but fix portability bug ]

Fix warning about undefined struct pt_regs.

Currently, all arches which support SMP define synchronize_irq(irq)
to be a real function (generally defined in arch/$(ARCH)/kernel/irq.c).
This export was removed inadvertanly I believe in the "bit IRQ lock"
removal and IRQ cleanups ChangeSet.
