Seeking test for https://reviews.freebsd.org/D20412

[Doug Moore]

I have  a patch to add to the arm32 v6 and v7 kernels inline calls to
ffs, fls, and the longer versions of them.  I've compiled for v6 and v7
and examined the resulting machine code, but that's not a test.  Is
anyone here willing to test this patch and verify that it breaks nothing?

Thanks for your help.
