bisect run success
Is that with gcc? Which compiler version?
I'll attach a patch proposal for you to try...
Created attachment 113670 [details] [review]
If you're using gcc, maybe a gcc version check would be better.
This patch also assumes the radeonsi driver isn't used on NetBSD (the only user of u_bit_scan64() at this time.)
$ gcc --version
gcc (NetBSD nb2 20110806) 4.5.3
