 Log Message:
 Apply patch, requested by dholland in ticket #1410:
        sys/arch/i386/i386/locore.S: patch
 In cpu_switch, avoid flipping interrupts on while holding the
 scheduler lock. Doing so can cause locking against oneself via
 endtsleep(). Fixes PR kern/38183, where the overt symptom was
 that LOCKDEBUG + INSTALL_LARGE would panic during boot.
 Should fix PR 38183.
