Schedule work away on an unmap, instead of calling it directly. Should result
in less lost samples, and it fixes a lock ordering problem buffer_sem <-> mmap_sem

Change the lost_mmap_sem stat to lost_no_mm, and account it.

We were doing del_timer_sync() on shutdown, but not ensuring that any queued work
was done as well.

Now we don't do buffer syncs whilst holding current's mmap_sem ever,
we can wait to hold it. Also take task_lock and try to improve the docs a bit.

If there's are multiple tasks sleeping inside the read routine ever, this is necessary.

Clear up the code around  start_sem so it's more obvious, and remove a pointless
down/up pair on buffer_sem (shutdown is already synchronised in sync_stop()).

Consolidate all the arch copies of timer_int.c into one place. Also fixes
a problem with PA-RISC not using instruction_pointer() when it should.

Convention is that error returns are negative.

- Consistent naming (i.e. jhash_xxx)
- Reduces the 2&1 word variants to call jhash_3words()
- Replaces __inline__ with inline.

Using sk_set_owner and having THIS_MODULE in the struct proto_ops
registered with the core. The sk_set_owner cases are in the callers
of tp->af_specific->syn_recv_sock so as to not have spurious extra
sk_set_owner calls in the ipv6 code that reuses ipv4 code.

Using sk_set_owner and having THIS_MODULE in the struct proto_ops
registered with the core, also remove the MOD_{INC,DEC}_USE_COUNT,
as they are not needed anymore with this new net module infrastructure
for struct sock and struct socket. (well, see the netdev discussion :)
