9 Write kernel log output directly into the VGA buffer or to a serial
10 port.

12 This is useful for kernel debugging when your machine crashes very
13 early before the console code is initialized. For normal operation
14 it is not recommended because it looks ugly and doesn't cooperate
15 with klogd/syslogd or the X server. You should normally N here,
16 unless you want to debug such a crash.

19 bool "Use 16Kb for kernel stacks instead of 8Kb"
20 help
21 If you say Y here the kernel will use a 16Kb stacksize for the
22 kernel stack attached to each process/thread. The default is 8K.
23 This increases the resident kernel footprint and will cause less
24 threads to run on the system and also increase the pressure
25 on the VM subsystem for higher order allocations.
