crypto: camellia - simplify key setup and CAMELLIA_ROUNDSM macro

camellia_setup_tail() applies 'inverse of the last half of P-function' to
subkeys, which is unneeded if keys are applied directly to yl/yr in
CAMELLIA_ROUNDSM.

Patch speeds up key setup and should speed up CAMELLIA_ROUNDSM as applying
key to yl/yr early has less register dependencies.

Quick tcrypt camellia results:
 x86_64, AMD Phenom II, ~5% faster
 x86_64, Intel Core 2, ~0.5% faster
 i386, Intel Atom N270, ~1% faster

crypto: camellia - add assembler implementation for x86_64

Patch adds x86_64 assembler implementation of Camellia block cipher. Two set of
functions are provided. First set is regular 'one-block at time' encrypt/decrypt
functions. Second is 'two-block at time' functions that gain performance increase
on out-of-order CPUs. Performance of 2-way functions should be equal to 1-way
functions with in-order CPUs.

Patch has been tested with tcrypt and automated filesystem tests.

We use the active cpumask to determine the superset of cpus

for internal usage of the scheduler and therefore not the

crypto: algapi - Move larval completion into algboss

It has been observed that sometimes the crypto allocation code
will get stuck for 60 seconds or multiples thereof.  This is
usually caused by an algorithm failing to pass the self-test.

If an algorithm fails to be constructed, we will immediately notify
all larval waiters.  However, if it succeeds in construction, but
then fails the self-test, we won't notify anyone at all.

This patch fixes this by merging the notification in the case
where the algorithm fails to be constructed with that of the
the case where it pases the self-test.  This way regardless of
what happens, we'll give the larval waiters an answer.
