i've done kernel compiles at various -j levels, and run some lmbench
benchmarks. 

as you know, there's also a memcpy testsuite that verified the main
copying algorithm for various block sizes and alignments.

i also have a small test program that is able to exercise the 
exception cases in the code, so i've tested the various load/store 
exception cases in the two functions (pa_memcpy and copy_dstaligned).

currently, the exception test program is a bit indirect (it requires a
lot of manual work). i have an idea for a better automated testsuite
which still needs to be implemented.
