Reintroduce uml_kmalloc for the benefit of UML libc code. The
previous tactic of declaring __kmalloc so it could be called directly
from the libc side of the house turned out to be getting too intimate
with slab, and it doesn't work with slob.
So, the uml_kmalloc wrapper is back. It calls kmalloc or whatever
that translates into, and libc code calls it.
kfree is left alone since that still works, leaving a somewhat
inconsistent API.

hppfs tidying and fixes noticed during hch's get_inode work -
style fixes
a copy_to_user got its return value checked
hppfs_write no longer fiddles file->f_pos because it gets and
returns pos in its arguments
hppfs_delete_inode dputs the underlyng procfs dentry stored in
its private data and mntputs the vfsmnt stashed in s_fs_info
hppfs_put_super no longer needs to mntput the s_fs_info, so it
no longer needs to exist
hppfs_readlink and hppfs_follow_link were doing a bunch of stuff
with a struct file which they didn't use
there is now a ->permission which calls generic_permission
get_inode was always returning 0 for some reason - it now
returns an inode if nothing bad happened

As of current mainline tree, TULIP driver is unusable on MPC8610HPCD
boards. There is a patch[1] floating around (and also included in the
BSP), which tries to heal the situation, though the ethernet is still
unusable. Practically it takes ages to mount NFS filesystem:
VFS: Mounted root (nfs filesystem).
Freeing unused kernel memory: 180k init
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 OK
nfs: server 10.0.0.2 not responding, still trying

nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 OK

So, instead of trying to add uli526x functionality into TULIP driver
(which is already bloated enough), I fixed existing ULI526X driver
and now it works perfectly well here.

When the hardware wavetable synthesizer of an Creative SB Audigy or SB
Live! card (with emu10k chip) receives the MIDI SOFT_PEADAL-press event
(?? 67 127) the appropriate voice is attenuted. Unfortunately when the
pedal is released (event ?? 67 0) the voice does not get it's original
volume again.
Boolean MIDI controls should interpret 0..63 as false and 64..127 as true.

If receiver consumes segments successfully only in-order, FRTO
fallback to conventional recovery produces RTO loop because
FRTO's forward transmissions will always get dropped and need to
be resent, yet by default they're not marked as lost (which are
the only segments we will retransmit in CA_Loss).
Price to pay about this is occassionally unnecessarily
retransmitting the forward transmission(s). SACK blocks help
a bit to avoid this, so it's mainly a concern for NewReno case
though SACK is not fully immune either.
This change has a side-effect of fixing SACKFRTO problem where
it didn't have snd_nxt of the RTO time available anymore when
fallback become necessary (this problem would have only occured
when RTO would occur for two or more segments and ECE arrives
in step 3; no need to figure out how to fix that unless the
TODO item of selective behavior is considered in future).

It seems that commit 009a2e3e4e ("[TCP] FRTO: Improve
interoperability with other undo_marker users") run into
another land-mine which caused fallback to conventional
recovery to break:
1. Cumulative ACK arrives after FRTO retransmission
2. tcp_try_to_open sees zero retrans_out, clears retrans_stamp
which should be kept like in CA_Loss state it would be
3. undo_marker change allowed tcp_packet_delayed to return
true because of the cleared retrans_stamp once FRTO is
terminated causing LossUndo to occur, which means all loss
markings FRTO made are reverted.
This means that the conventional recovery basically recovered
one loss per RTT, which is not that efficient. It was quite
unobvious that the undo_marker change broken something like
this, I had a quite long session to track it down because of
the non-intuitiviness of the bug (luckily I had a trivial
reproducer at hand and I was also able to learn to use kprobes
in the process as well :-)).
This together with the NewReno+FRTO fix and FRTO in-order
workaround this fixes Damon's problems, this and the first
mentioned are enough to fix Bugzilla #10063.
