Looks like they escaped your notice

Yes this is big but 2.4 has been indented, updated and there wasnt a
sane way to deal with it

There are some bits left to do but this folds in all the main stuff from
2.4 and 2.5 including Al's recent change

This doesnt fix all the isdn code but it sorts out the tqueue stuff so we
are no worse than before

Linus, this has been tested by some people in the field to not break
things, and it's the start of some other changes I'm making, so please put
this in your tree so I'm not merging huge patches but instead am merging a
little as I go.

This enables tagged command queueing support in the ide layer again and
marks it as an experimental feature.

This changes the way we do pool lookups when freeing a bio.  Right now
we use bi_max as a handle into bvec_array[], to find the pool where it
came from.  This used to be just fine, because if you had a private bio,
you could specify your own destructor.  But now we have bio_add_page()
which also needs to know where the bio came from, or more precisely, it
needs to know how many entries the bio can hold.

So I've changed bi_max to bi_max_vecs, it now contains the number of vec
entries in the bio. Privately allocated bio's (or on stack) can now just
set bio->bi_max_vecs to reflect the max size. The pool index for the
default destructor is stored in the top bits of bi_flags.

Make things static, and remove hardcoded value

As per comment..

Hide ISA only drivers during configuration..

From Pavel Machek. Without these two lines,
the throttling limits are never reached, and a machine
will happily cook itself.

Sammy changed address, and lets BUG() instead of
locking up the machine.

Daniel Phillips' indexed directory support.  Ported from ext2 by
Christopher Li.  Contributions from Andreas Dilger, Stephen Tweedie,
lots from Ted.

It requires e2fsprogs-1.29; I've updated the Changes file to reflect
that.

From Bill Irwin

The simple_link(), simple_unlink(), simple_rename(),
simple_sync_file(), simple_rmdir(), and simple_empty() functions are
easy to duplicate.  Basically, I duplicated them in an fs patch of
mine, and Linus told me to put them in libfs.c

Pat Mochel has acked the changes for driverfs (in that he'll convert
the stuff over when they're available from libfs), and my hugetlbfs
implementation was the thing that spurred the whole incident.

From Christoph Hellwig.

If we always pass &contig_page_data into free_area_init_node for the
non-distcontig case we can merge both versions of that function into
one.  Move that one to page_alloc.c and thus kill numa.c which was
totally misnamed, btw.

Patch from Christoph Hellwig

It turns alloc_pages_node into a static inline, in the same fashion as
alloc_pages.  There is no need for #ifdef CONFIG_NUMA in the patch, as
the numa node identification functions are sensible enough to do the
right thing for non-NUMA systems.  Moves alloc_pages_node from numa.c
to gfp.h, and removes the EXPORT_SYMBOL which is no longer needed as
this is now an inline.

This used to be a macro wrapper around get_zeroed_page().

It was a dreadful choice of name, because it hid the fact that this
function memsets the page.  Probably, lots of the callers didn't
actually want to do that but this patch does not make such
optimisations.

At least now, people may spot a `get_zeroed_page' in there and realise
that the page doesn't actually need to be initialised.

The patch also changes get_zeroed_page() to go BUG if called with
__GFP_HIGHMEM.  It returns the address of the page's memory and hence
can only be used for direct-mapped pages (wli).
