  14           task has ever had available in the sysrq-T output.

  20           Say Y here if you want to have an early console using the
  21           earlyprintk=<name>[,<addr>][,<options>] kernel parameter. It
  22           is assumed that the early console device has been initialised
  23           by the boot loader prior to starting the Linux kernel.

  25 config PID_IN_CONTEXTIDR
  26         bool "Write the current PID to the CONTEXTIDR register"
  27         help
  28           Enabling this option causes the kernel to write the current PID to
  29           the CONTEXTIDR register, at the expense of some additional
  30           instructions during context switch. Say Y here only if you are
  31           planning to use hardware trace tools with this kernel.
