Code with apache-2 on /usr/src

[Adhemerval Zanella]

Hi all,

I am evaluating adding the ARM optimized math routines [1] on FreeBSD msum
library and I would like to check which the policy regarding licensing on
/usr/src code.  The optimized math code is licensed on Apache-2 and afaik
it should be compatible with FreeBSD BDS license, is there anything
impending to use the code as-is on msum? Or do I need to adjust and check
with author if the idea is re-license?
