   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.

  18config 16KSTACKS
  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.
