   9           This allows profiling of a User-Mode Linux kernel with the gprof
  10           utility.

  15           If you're involved in UML kernel development and want to use gprof,
  16           say Y.  If you're unsure, say N.

  35           Track the maximum kernel stack usage - this will look at each
  36           kernel stack at process exit and log it if it's the deepest
  37           stack seen so far.
  38
  39           This option will slow down process creation and destruction somewhat.
