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.

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.

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

Make the 144 files in fs/ that need it include buffer_head.h directly.
Again some uses in the VFS files are layering violations and need to
be addressed later.  The new include statement gives a nice grep pattern
for that :)

Make kernel/ksyms.c include buffer_head.h directly.

Make the 5 headers in include/linux that need it include buffer_head.h
directly.

Make the 7 file that need it in mm/ include buffer_head.h directly.
Once again most files shouln't need it and want fixing.

Include buffer_head.h directly in the file in drivers/ that need it
(9 files).  Note that most of this uses are layering violations that I
will address later.

Remove two unused declarations in fs/jffs/intrep.h.

Remove unused bh_kmap/bh_kunmap inlines from highmem.h.

Declare buffer_init() extern in init/main.c like the other _init so that
it doesn't have to include buffer_head.h.  Remove buffer_init() there.

Now that fs.h grow due to the lock.h removal let's reduce it's overhead
again:  Instead of penalizing ever user of fs.h with the overhead of the
buffer head interface let it's users include it directly.

This also shows nicely which parts of the core kernel still depend on the
buffer head interface, and allows that to be cleaned up properly.

This is the first of ten patches and adds the includes needed by
buffer_head.h to it and fixes it's inclusion guard.

We now always allocate the section __ksymtab, which to modutils means
not to implicitly export any symbols.

That means that EXPORT_NO_SYMBOLS is now default, and thus can go away
in the sources.

o Standardize building math-emu.o for arch/alpha
o Remove old boilerplate code / redundant comments
o Remove unnecessary obj-m := $(sort $(obj-m)) in ALSA

o Use a shorter expression to transform 'foo.o' -> 'foo-objs'
o Define EXPORT_FLAGS (as -DEXPORT_SYMTAB) in the main Makefile
o Small rearrangement of code in Rules.make
