 Log Message:
 Map kernel stack and "struct cpuinfo" of secondary processors with
 execute permission. (I don't understand yet why the latter is needed.)
 This fixes crashes of MP kernels reported by Kurt Schreiner and in
 the context of PR port-amd64/33927 (which is about a different problem
 otherwise).
 MP kernels reported to boot again by Dave Huang and Kurt Schreiner.
