Subject: PR/39349 CVS commit: src/sys

 Module Name:   src
 Committed By:  rmind
 Date:          Fri Oct 31 00:36:22 UTC 2008
 Modified Files:
        src/sys/arch/x86/x86: cpu.c
        src/sys/arch/xen/x86: cpu.c
        src/sys/kern: kern_cpu.c sys_sched.c
        src/sys/sys: cpu.h
 Log Message:
 - Avoid the race with CPU online/offline state changes, when setting the
   affinity (cpu_lock protects these operations now).
 - Disallow setting of state of CPU to to offline, if there are bound LWPs,
   which have no CPU to migrate.
 - Disallow setting of affinity for the LWP(s), if all CPUs in the dynamic
   CPU-set are offline.
 - sched_setaffinity: fix invalid check of kcpuset_isset().
 - Rename cpu_setonline() to cpu_setstate().
 Should fix PR/39349.
