Trivial patch against Linux 2.6.10 which adds PNP support for a
certain kind of Rockwell 28.8/ISA modems.

Fix a 4-level page table bug that slipped through (introduced by me,
not Andi).

Compiles and boots on ia64 and 2-level i386.

Pretty much all the TF-related comments were stale, and
had been for a long time. Fix them up, clean up code.

PT_DTRACE without PT_PTRACED.

Long ago, the "D" in PT_DTRACE meant "Delayed", and it was used
as a flag to mark that we had ptrace'd the process but no longer
did so. That hasn't been true in a while now, and the flag should
probably be renamed, but in the meantime the test for PT_PTRACED
being cleared had been corrupted into something totally nonsensical.

Pointed out by Andi Kleen.

Quieten down compiler warnings, and fix an off-by-one bug when
deciding whether to include the next word.

into ppc970.osdl.org:/home/torvalds/v2.6/linux

It didn't allocate space for the final terminating entry,
which caused it to overwrite the next slab entry, which in turn
sometimes ended up being a slab array cache pointer. End result:
total slab cache corruption at a random time afterwards. Very
nasty.

some trivial iomem annotations were still missing

Someone thought it would be clever if proc code ignores removal of
non-existent entries.  Hence, we missed that /proc/net/stat/ip_conntrack
is never removed on module removal or init failure.

The latter hunk of the forwarded patch has already been applied, so
please apply the patch as it appears in the un-forwarded part. I've
taken some liberties in adding the Acked/Signed-off lines in what I
hope is an agreeable way.

Add a temporary "fallback" header so architectures can run with the 4level
patgetables patch without modification. All architectures should be
converted to use the folding headers (include/asm-generic/pgtable-nop?d.h)
as soon as possible, and the fallback header removed.

Make all architectures include the fallback header, except i386, because that
architecture has earlier been converted to use pgtable-nopmd.h under the 3
level system, which is not compatible with the fallback header.
