The axnet_cs driver can support the AMB8110 PC Card, so add the id for it.

In the old pcmcia-cs config file, this card is listed with the comment "not
specific enough".  The last entry in the axnet_ids has the same comment.
They are disabled, and for good reason as it was originally identified by
the MANFID, and that is shared with several cards that use both the
pcnet_cs driver and axnet_cs driver.  I tried my AMB8110 with pcnet_cs, and
found that it works fine, and I cannot find a reason for either, except
that the old config file recommended axnet_cs.

This patch adds mm->task_size to keep track of the task size of a given mm
and uses that to fix the powerpc vdso so that it uses the mm task size to
decide what pages to fault in instead of the current thread flags (which
broke when ptracing).

(akpm: I expect that mm_struct.task_size will become the way in which we
finally sort out the confusion between 32-bit processes and 32-bit mm's.  It
may need tweaks, but at this stage this patch is powerpc-only.)

remove_from_swap() currently attempts to use page_lock_anon_vma to obtain
an anon_vma lock.  That is not working since the page may have been
remapped via swap ptes in order to move the page.

However, do_migrate_pages() obtain the mmap_sem lock and therefore there is
a guarantee that the anonymous vma will not vanish from under us.  There is
therefore no need to use page_lock_anon_vma.

The RedBoot boot loader writes flash partition tables containing native
byte sex 32 bit values.  When booting an opposite byte sex kernel (e.g.  an
LE kernel from BE RedBoot) the current MTD driver fails to handle the
partition table and therefore is unable to generate the correct partition
map for the flash.

So far as I am aware this problem is ARM specific, because only ARM
supports software change of the CPU (memory system) byte sex, however the
partition table parsing is in generic MTD code.  The patch below has been
tested on NSLU2 (an IXP4XX based system) with a patch,
10-ixp4xx-copy-from.patch (submitted to linux-arm-kernel - it's ARM
specific) required to make the maps/ixp4xx.c driver work with an LE kernel.

Builds of the patched system are in the 'unstable' release of OpenSlug and
UcSlugC available from www.nslu2-linux.org.  These builds are BE, the
archives at www.nslu2-linux.org and www.handhelds.org (see
monotone.vanille.de) can be built LE (currently DISTRO targets
nslu-ltu.conf for LE thumb uclibc (32 bit kernel) and nslu2-lau.conf,
nslu2-lag.conf for LE arm uclibc/glibc) and this patch has been tested
extensively will both BE and LE systems on the NSLU2 (including swapping
between BE and LE by reflashing from both RedBoot and Linux).

The patch recognises that the FIS directory (the partition table) is
byte-reversed by examining the partition table size, which is known to be
one erase block (this is an assumption made elsewhere in redboot.c).  If
the size matches the erase block after byte swapping the value then
byte-reversal is assumed, if not no further action is taken.  The patched
code is fail safe; should redboot.c be changed to support a partition table
with a modified size field the test will fail and the partition table will
be assumed to have the host byte sex.

If byte-reversal is detected the patch byte swaps the remainder of the 32
bit fields in the copy of the table; this copy is then used to set up the
MTD partition map.

If negative entries (nodeid == 0) were sent in reply to LOOKUP requests,
two bugs could be triggered:

- looking up a negative entry would return -EIO,

- revaildate on an entry which turned negative would send a FORGET
  request with zero nodeid, which would cause an abort() in the
  library.

The above would only happen if the 'negative_timeout=N' option was used,
otherwise lookups reply -ENOENT, which worked correctly.
