   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.

  39          This option will slow down process creation and destruction somewhat.
