The rewritten makefile for DocBook requires that working directory
is $(TOPDIR) therefore use -f Documentation/DocBook/Makefile to
invoke the docbook makefile.

To support the new DocBook makefile the script target needs to be located
the block that is checked for precense of a .config file.

kernel-doc-nano-HOWTO.txt updated to reflect new functionality
provided by docproc.
gen-all-syms and docgen description removed.
kernel-api.tmpl and parportbook.tmpl updated to specify files to search
for EXPORT-SYMBOL* to enable documentation of all relevant functions.

Massive cleanup of makefile.
Comments added as well.
Enabled by the new functionality provided by docproc
When generating HTML locate a new file in DocBook dir that points to
the book in question.

This is the first patch in a serie to clean-up the DocBook
Makefile.

docproc is extented to include the functionality previously provided by
gen-all-syms and docgen.  Furthermore the necessity to specify which
files to search for EXPORT_SYMBOL are removed, the information is now
read in the .tmpl files.

docproc is furthermore extended to generate dependency information.
gen-all-syms and docgen are deleted.

During processing of skbuff.h three warnings were issued,
because members of an enum within a struct were nor documented.
This patch fixes kernel-doc not to spit out these non-valid warnings.

This removes cli/sti from SPX registration code in IPX.  I decided to
use normal rw_semaphore instead of net_family_{write,read}_{lock,unlock}
used in net/socket.c.

I left SPX code itself alone: I do not use it and last time I checked it
it was very unreliable reliable transport.

This patch for 2.5.28 fixes two explicit accesses to thread_info->cpu
in generic code to use the new UP-optimised macros instead.

This patch for 2.5.28 reduces the stack frame size of
arch/i386/kernel/nmi.c:check_nmi_watchdog() from 4096 bytes
in the worst case to 128 bytes.

The problem with the current code is that it copies the entire
irq_stat[] array, when only a single field (__nmi_count) is of
interest. The irq_stat_t element type is only 28 bytes, but it
is also ____cacheline_aligned, and that blows the array up to
4096 bytes on SMP P4 Xeons, 2048 bytes on SMP K7s, and 1024 bytes
on SMP P5/P6s. The patch reduces this to NR_CPUS*4==128 bytes.

I've noticed that xtime_lock and timerlist_lock ends up on the same
cacheline  all the time (atleaset on x86).  Not a good thing for
loads with high xxx_timer and do_gettimeofday counts I guess (networking etc).

Here's a trivial fix.

This is a complete rewrite of the LDM driver (support for Windows
Dynamic Disks).  It incorporates Al Viro's recent partition handling
tidy ups.

Details:
  LDM Driver rewritten.  More efficient.  Much smaller memory footprint.

  The old driver was little more than a stopgap.
  The new driver is a complete rewrite
  based on a much better understanding of the database
  based on much more reverse engineering
  more able to spot errors and inconsistancies
  it has a much smaller memory footprint
  no longer considered experimental
  accompanied by brief info: Documentation/ldm.txt

On a ppc64 machine running 2.5.28 we were hitting this BUG in
__free_pages_ok:

BUG_ON(page->pte.chain != NULL);

In pte_chain_lock we use test_and_set_bit which implies a memory
barrier. In pte_chain_unlock we use clear_bit which has no memory
barriers so we need to add one.

Here's a patch from Christoph Hellwig and myself to supply write->read
semaphore downgrade, and also from Brian Watson to supply trylock for rwsems.

Make sure the cpu argument to cpu_online() is evaluated for
side effects on UP too.

Things look rather like this..

Rename input_devinfo to input_id, it's shorter and more 
to the point.
Remove superfluous printks in uinput.c
Clean up return values in evdev.c ioctl. 

comes to directions of movement and rotation, a mouse wheel should
be positive where it "rotates forward, away from the user". We had
the opposite in psmouse.c. Fixed this.

converter to atkbd.c - trivial. Remove ps2serkbd, because it's
not needed anymore.

is mousedev.c to properly merge events into PS/2 packets.
