This patch fixes the case of an ABORT happening during the auto-sense
processing when using the ISD-200 driver.

Once upon a time, the SCSI command structure could only hold a maximum of
12 bytes.  Thus, the ISD-200 driver needed an entirely separate function to
work with 16-byte commands.

Now that 16-bytes is stored, we can cut the duplicates.

Since we now test for aborts at a higher level, the low-level end of the
drivers don't need to be constantly testing for aborts.  This patch removes
that excess logic.

(Yes, they should probably use __stringify() instead).

This patch provides basic x86 support for modules.

This is an implementation of the in-kernel module loader extending
the try_inc_mod_count() primitive and making its use compulsory.
This has the benifit of simplicity, and similarity to the existing
scheme.  To reduce the cost of the constant increments and
decrements, reference counters are lockless and per-cpu.

Eliminated (coming in following patches):
 o Modversions
 o Module parameters
 o kallsyms
 o EXPORT_SYMBOL_GPL and MODULE_LICENCE checks
 o DEVICE_TABLE support.

New features:
 o Typesafe symbol_get/symbol_put
 o Single "insert this module" syscall interface allows trivial userspace.
 o Raceless loading and unloading

By Kai Germaschewski.

This patch adds a -DKBUILD_MODNAME to the kernel compile, which
contains the base of the module name which is being built.

 - Some sreorganization of the c_flags since they're needed for
   generating modversions (.ver) and compiling
 - Use the right KBUILD_MODNAME also when the user just wants a .i/.s/.lst
   file for debugging and also when generating modversions
 - It looks like with your current approach you can't have a ',' or '-' in
   KBUILD_MODNAME - however, that means that KBUILD_MODNAME is not quite
   right for passing module parameters for built-in modules on the command
   line, it would be confusing to pass parameters for ide-cd as
   ide_cd.foo=whatever. So that part could use a little more thought.
 - If you think your module_names trick makes a noticable difference, feel
   free to re-add it.
 - It's possible that objects are linked into more than one module - I
   suppose this shouldn't be a problem, since these objects hopefully
   don't have a module_init() nor do they export symbols. Not sure if your
   patch did handle this.

 - compile fixes in amiflop.c
 - removal of dead local variables in ll_rw_blk.c
 - removed gratitious devfs_get_handle() in usb/input/hiddev.c
   (no need to do lookup for "usb" and then create "hid" in
   there - enough to create "usb/hid" at once).

dasd.c forgot to set ->private_data, but was using it ;-/  Fixed.

Remaining dasd_devmap_from_kdev() callers switched to
dasd_devmap_from_bdev() (other than call from dasd_devmap_from_bdev(),
that is).

dasd_devmap_from_kdev() merged into dasd_devmap_from_bdev().

Eliminated several gratitious ->bd_dev uses.

Bunch of kdevname() uses replaced with bdevname().

__bdevname() switched from kdev_t to dev_t; callers updated.

Compile fixes, cleanup.

RAID autoconfig rewritten to use syscalls and moved into do_mounts.c;
use of devfs_get_handle() in do_mounts.c also rewritten in syscalls.

paride/pseudo.h fed through Lindent, use of timer replaced with
schedule_delayed_work() - that's what the old code tried to emulate.

Instead of user_path_walk() and comparing dentries, sys_swapoff()
opens its argument and compares ->i_mapping.  Result: slightly
simpler code and swapoff(2) becomes tolerant to e.g.

	swapon /dev/sda2
	switch root from initrd to sda1
	....
	swapoff /dev/sda2  # where /dev is from sda1, not from initrd

current tree fails in the case above (different dentries -> no love).

Spotted by Andries - cloning namespace assumes that new tree is
congruent to the old one (when switching root/cwd) but actually
inverts the order of children in each node.

Buffer I/O error on device loop: its use of sendfile is (trivially)
broken - retval is usually count done, only an error when negative.

This code (like the old one) does not correctly handle partial reads.

Nearby spinlocking clearly bogus, delete instead of remarking on it.

This file was somehow skipped (along with jfs_acl.h> when I checked in
the ACL support.

This patch will break some userspace monitoring apps in the name of
having sane disk statistics in 2.6.x.

Patch from Rick Lindsley <ricklind@us.ibm.com>

In 2.5.46, there are now disk statistics being collected twice: once
for gendisk/hd_struct, and once for dkstat.  They are collecting the
same thing.  This patch removes dkstat, which also had the disadvantage
of being limited by DK_MAX_MAJOR and DK_MAX_DISK. (Those #defines are
removed too.)

In addition, this patch removes disk statistics from /proc/stat since
they are now available via sysfs and there seems to have been a general
preference in previous discussions to "clean up" /proc/stat.  Too many
disks being reported in /proc/stat also caused buffer overflows when
trying to print out the data.

The code in led.c from the parisc architecture has not apparently been
recompiled under recent versions of 2.5, since it references
kstat.dk_drive which doesn't exist in later versions.  Accordingly,
I've added an #ifdef 0 and a comment to that code so that it may at
least compile, albeit without one feature -- a step up from its state
now.  If it is preferable to keep the broken code in, that patch may
easily be excised from below.

We're currently incrementing /proc/vmstat:pgalloc in front of the
per-cpu page queues, and incrementing /proc/vmstat:pgfree behind the
per-cpu queues.  So they get out of whack.

Change it so that we increment the counters each time someone requests
a page.  ie: they're both in front of the queues.

Also, remove a duplicated prep_new_page() call and as a consequence,
drop the whole additional list walk in rmqueue_bulk().

There was some strange code in the __getblk()/__find_get_block()/
__bread() area which was performimg multiple bh_lru_install() calls as
well as multiple touch_buffer() calls.

Fix all that up.  We only need to run bh_lru_install() and
touch_buffer() in __find_get_block().  Because if the block wasn't
found, __getblk() will create it and will re-run __find_get_block().

Also document a few things and make a couple of internal symbols static
to buffer.c

Also, don't run __find_get_block() from within
unmap_underlying_metadata().  We hardly expect to find that block
inside the LRU.  And we hardly expect to use it as metadata in the near
future so there's no point in letting it evict another buffer if we
found it.  So just go straight into the pagecache lookup for
unmap_underlying_metadata().

The disk accounting will overflow after 4,000,000 seconds.  Extend that
by a factor of 1000.
