It's possible to say "make <subdir>", to descend into that subdir
and recursively build things there. This patch provides this
facility generally without the arch Makefiles needing to duplicate
it for arch/$(ARCH)/somedir.

We now have the information which objects are being built
modular / built-in in Rules.make, so use this information instead
of passing flags to the sub makes.

Didn't get the net/ conversion quite right, and apparently overlooked
one subdir in sound/. Now fixed.

Use the new

	obj-$(CONFIG_FOO) += foo/

syntax to descend into a subdir and link in the result, if
CONFIG_FOO=y.

Build the headers only when we need them during the build, not always
at 'make dep' time.

We use O_TARGET everywhere else, so let's just convert the remaining
users (They get the implicit built-in.o O_TARGET now)

(plus a bit of rearranging in the ISDN Makefiles) 

If a Makefile defines neither O_TARGET nor L_TARGET, let's assume a
default of 'built-in.o'. The goal of this is, of course, to eventually
get rid of O_TARGET completely.

 - move the contents of bdev_get_queue() into do_open() and
   check_partitions() and cache the result in new field of struct
   block_device

 - clean it at the same places that reset ->bd_op, etc.

 - make bdev_get_queue() return cached pointer.

 - kill the last caller of get_hardsect_size() (switching it to
   bdev_hardsect_size()).

 - kill blk_get_queue() and switching to bdev_get_queue()

  - make sure return codes are negative (i.e. return -ENOMEM and not return ENOMEM et al)

Fixes a warning in ieee1394_types.h and an error in include/linux/usb.h

This kills unneccessary include from ide-disk.c, kills #ifdef from
reiserfs/journal.c, makes suspend_device local as it should be,
abstains from suspending devices two times in a row (typo), and makes
sure we do not run_task_queue() while we hold spinlock.

I asked Gabor if he'd like me to maintain swsusp, and he liked that
idea [<quote>Would you please take over maintaining? I offered this in
the list a while ago anyway.</quote>].

These are cleanups. They do not change any code, except killing
printk's.

 - Apply host chip driver cleanups by Bartomiej Zonierkiewicz.

 - Take the draft device type driver implementation from Adam Richter and make
    it actually work with some of the drivers we have at hand. Quite a lot
    of it was fixed by me as well to have the desired effects.

    We have added a attach method for the sub device type drivers to make it
    possible dor sub device type drivers to attach devices to the overall
    infrastructure. UNIX has something like this SCSI code is implementing
    something like this, just for some unknown reasons Linux block device
    operations don't have it...

 - ide_drive_t is finally gone. Please use struct ata_device instead.

    Hint the ide.h specific byte type should go over time as well, sine there
    is no need to invent something already handled by the kernel. Please use
    the unambigious u8 type instead where possible.

 - Add a bit of documentation about cabling issues. ide.txt needs a lot of
   improvement at some time still.

__initcalls are supposed to return a value.
Statically initialize the struct instead of doing strcpy() at runtime.

Needs static, otherwise one gets multiple definitions in the final
vmlinux image.

No more need to include buffer_head.h in fs.h.  Finally.
