 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.
