361512da0d This commit completes recent modular exponentiation optimizations on 
x86_64 platform. It targets specifically RSA1024 sign (using ideas
from http://eprint.iacr.org/2011/239) and adds more than 10% on most
platforms. Overall performance improvement relative to 1.0.0 is ~40%
in average, with best result of 54% on Westmere. Incidentally ~40%
is average improvement even for longer key lengths.

3efe51a407 Revert previous Linux-specific/centric commit#19629. If it really has to 
be done, it's definitely not the way to do it. So far answer to the
question was to ./config -Wa,--noexecstack (adopted by RedHat).

964ed94649 parisc-mont.pl: PA-RISC 2.0 code path optimization based on intruction- 
level profiling data resulted in almost 50% performance improvement.
PA-RISC 1.1 is also reordered in same manner, mostly to be consistent,
as no gain was observed, not on PA-7100LC.
