  13        help
  14          If you say Y here then read-write lock processing will count how many
  15          times it has tried to get the lock and issue an error message after
  16          too many attempts.  If you suspect a rwlock problem or a kernel
  17          hacker asks for this option then say Y.  Otherwise say N.

  22        help
  23          If you say Y here then semaphore processing will issue lots of
  24          verbose debugging messages.  If you suspect a semaphore problem or a
  25          kernel hacker asks for this option then say Y.  Otherwise say N.

  31        ---help---
  32          The 2.4 kernel changed the kernel start address from 0x310000
  33          to 0x810000 to make room for the Wildfire's larger SRM console.
  34          Recent consoles on Titan and Marvel machines also require the
  35          extra room.
  36
  37          If you're using aboot 0.7 or later, the bootloader will examine the
  38          ELF headers to determine where to transfer control. Unfortunately,
  39          most older bootloaders -- APB or MILO -- hardcoded the kernel start
  40          address rather than examining the ELF headers, and the result is a
  41          hard lockup.
  42
  43          Say Y if you have a broken bootloader.  Say N if you do not, or if
  44          you wish to run on Wildfire, Titan, or Marvel.

  54        help
  55          This option is required for IEEE compliant floating point arithmetic
  56          on the Alpha. The only time you would ever not say Y is to say M in
  57          order to debug the code. Say Y unless you know what you are doing.
