>Description:
When build kernel use the "option DEVICE_POLLING" with "option SMP", it'll
fail:
.....
/usr/src/sys/kern/kern_lock.c:646: #error "SIMPLELOCK_DEBUG is not 
compatible with
SMP!"
/usr/src/sys/kern/kern_poll.c:43: #error DEVICE_POLLING is not compatible 
with
SMP
.....
But it is not mentioned in LINT
>How-To-Repeat:
make kernel, use "option DEVICE_POLLING" & "option SMP" in the same config
file.
>Fix:
I think it should be mentioned in LINT(for 4.x) & NOTES(for 5.0).
