sys/i386/i386 vm_machdep.c
Log:
Initialize pcb_mpnest to 1 in the child process in cpu_fork(). This should
fix the 50% idle problem that the ELF /sbin/init triggered. The problem
appeared when the last context switch before a fork() call was due to
the kernel faulting in user pages via normal page faults (e.g. copyin).
