attilio 2010-08-09 00:23:57 UTC FreeBSD src repository Modified files: sys/kern subr_smp.c Log: SVN rev 211087 on 2010-08-09 00:23:57Z by attilio The r208165 fixed a bug related to unsigned integer overflowing for the number of CPUs detection. However, that was not mention at all, the problem was not reported, the patch has not been MFCed and the fix is mostly improper. Fix the original overflow (caused when 32 CPUs must be detected) by just using a different mathematical computation (it also makes more explicit the size of operands involved, which is good in the moment waiting for a more complete support for a large number of CPUs).
