John, this commit went into -current almost 2 years ago with "MFC After: 1 month" tag Did something went wrong? ------------------------------------------------------------------------ r270223 | jhb | 2014-08-20 20:06:24 +0400 (Wed, 20 Aug 2014) | 5 lines Bump MAXCPU on amd64 from 64 to 256. In practice APIC only permits 255 CPUs (IDs 0 through 254). Getting above that limit requires x2APIC.

The cpuset_getaffinity(2) and cpuset_setaffinity(2) check minimum set size, which now fails for binaries compiled on 10.0 with MAXCPU == 64. Submitted by: jhb PR: 200802 -- Herbert
