- 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.

Run-tested with tcrypt module.

- Macro parameters renamed for clarity.

- Inaccurate comments fixed.

- ebp register usage de-obfuscated (this is needed for next patch).

No real code changes.

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
6649        372       0    7021    1b6d sha512.o

# objdump -d sha512.o.org | cut -b9- >sha512.d.org
# objdump -d sha512.o | cut -b9- >sha512.d
# diff -u sha512.d.org sha512.d

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 )

This patch fixes a bug in the DECnet connect that seems to have been in 2.6 for
a while now.

If a connection is rejected by a remote host (eg invalid access control, no
such object etc) the Linux end hangs in connect() because it is only waiting for
the socket to go into RUN state.

This patch sets the ECONNREFUSED error state on the socket when the connection
is rejected to that the connect() exits it's wait loop and returns the error to
the user.

Since skb_checksum_help has been using pskb_expand_head for a while
now without any ill effects, I thought it would be a good idea to
remove the double pointers from it and its callers.

This is what the following patch does.  The only 'rider' bit is the
removal of an unnecessary BUG_ON in ip6_pkt_discard_out.  The preceding
assignment was only added because the following function oopsed so
there is no point in doing BUG_ON.

  - hdrlen may underflow.
  - (u16)*optdesc causes to alignment problem.
  - The calculation of the offset to next option is wrong. In the case

The stop_self thing is accessed unconditionally from pSeries_setup.c

This will get rid of the stack recursion possibility that can occur if
an IRQ happens to hit the IRQ return path right after we've reset
preempt_count() to 0 and are about to disable interrupts again.
Trivially fixed by just moving the preempt count update to inside the
interrupt disable.

This makes the current PREEMPT_ACTIVE method fully work for IRQ
recursions.

Avoid naming confusion concerning "pc_debug" which is widely used by drivers
be renaming the PCMCIA "driver services" variant to ds_pc_debug. The module
parameter stays the same, thanks to module_param_named().
