760e353528 sparcv9a-mont was modified to handle 32-bit aligned input, but check 
for 64-bit alignment was not removed.

1c3d2b94be This is "informational" commit. Its mere purpose is to expose "modulo 
factor" in inner loops.

3b4a0225e2 As SPARCV9 CPU flavor is [expected to be] detected at run-time, we can 
afford to relax SPARCV9/8+ compiler command line and produce "unversal"

Andy Polyakov
6df8c74d5b Switch 64-bit sparcv9 platforms from bn(64,64) to bn(64,32). This doesn't 
have impact on performance, because amount of multiplications does not
increase with this switch, not on sparcv9 that is. On the contrary, it
actually improves performance, because it spares a load of instructions
used to chase carries. Not to mention that BN assembler modules can be
shared more freely between 32- and 64-bit builts.
