ide-iops.c exports a few functions that either have no users or have no
users AND shouldn't be used by drivers; the patch below unexports them.

-EXPORT_SYMBOL(SELECT_INTERRUPT);
-EXPORT_SYMBOL(SELECT_MASK);
-EXPORT_SYMBOL(QUIRK_LIST);
-EXPORT_SYMBOL(ata_vlb_sync);

only used in the core ide code

-EXPORT_SYMBOL(ata_input_data);
-EXPORT_SYMBOL(ata_output_data);

drivers should (and do) use the hwif-> function pointer variant of these,
these functions are internal and used for setting the default hwif->
function pointers only. No need to export, in fact exporting is only asking
for accidents

In general it is not safe to do any non-ptrace wakeup of a thread in
TASK_TRACED, because the waking thread could race with a ptrace call
that could be doing things like mucking directly with its kernel stack. 

AFAIK noone has established that whatever clobberation ptrace can do to
a running thread is safe even if it will never return to user mode, so
we can't allow this even for SIGKILL.

What we _can_ safely do is make a thread switching out of TASK_TRACED
resume rather than sitting in TASK_STOPPED if it has a pending SIGKILL
or SIGCONT.  The following patch does this.

This should be sufficient for the shutdown case.  When killing all
processes, if the tracer gets killed first, the tracee goes into
TASK_STOPPED and will be woken and killed by the SIGKILL (same as
before).  If the tracee gets killed first, it gets a pending SIGKILL and
doesn't wake up immediately--but, now, when the tracer gets killed, the
tracee will then wake up to die. 

This will also fix the (same) situations that can arise now where you
have used gdb (or whatever ptrace caller), killed -9 the gdb and the
process being debugged, but still have to kill -CONT the process before
it goes away (now it should just go away either the first time or when
you kill gdb).

My latest 8250 patch prevented registration of "empty" ports (ports that

The ppc64 PCI code, when parsing the OF tree, may end up getting empty
regions in addition to the "normal" ones for the PHB (some pSeries OF
device-tree contains weird "ranges" properties). These are harmless but
do trigger some annoying warnings during boot, so let's ignore them.

Actually, I think we've caught your crash now.  If that code path
is triggering at all, then it'll trigger with TSO packets too.  If
we get a truly partial ack on a TSO packet, then tcp_tso_acked will
not trim it off.  So we will fall through to this last-ditch trim
call, which doesn't update packets_out.

There are two solutions to this problem.  I've taken the simpler
approach for now.  We simply trim off the partial bits in tcp_tso_acked
and live with the fact that the packet counters may differ from
what's on the netwrok by one.

Later on we can 'fix' this by remembering where the original TSO
packet started from, perhaps in skb->h or somewhere.  Dave, is this
worth it?

- recode back-to-back fwd_rnd() pairs to avoid two register moves.

- ditto for inv_rnd().

- optimize out lea 0(%ebp),%ebp

- remove two stray insns

# size aes-i586-asm.o.org aes-i586-asm.o
   text    data     bss     dec     hex filename
   5971       0       0    5971    1753 aes-i586-asm.o.org
   5905       0       0    5905    1711 aes-i586-asm.o

Overall, patch does not add and does not modify any insns, only removes a
handful of them.  However, speed difference is way below noise level.

Patch moves large temporary u64 W[80] from stack to ctx struct:

* reduces stack usage by 640 bytes
* saves one 640-byte memset() per sha512_transform()
  (we still do it after *all* iterations are done)
* quite unexpectedly saves 1.6k of code on i386
  because stack offsets now fit into 8bits
  and many stack addressing insns got 3 bytes smaller:

# size sha512.o.org sha512.o
text       data     bss     dec     hex filename
8281        372       0    8653    21cd sha512.o.org

Looks like open-coded be_to_cpu.  GCC produces rather poor code for this. 
be_to_cpu produces asm()s which are ~4 times shorter.

Compile-tested only.

I am not sure whether input can be 64bit-unaligned.
If it indeed can be, replace:

((u64*)(input))[I]  ->  get_unaligned( ((u64*)(input))+I )
