  19           Support checking of versions for modules.  This is used to
  20           ensure that the kernel and module are made for each other.

  27           By adding module symbols to the kernel symbol table, Oops messages
  28           occuring within kernel modules can be properly debugged.  By enabling
  29           this feature, module symbols will always be added to the kernel symbol
  30           table for properly debugging support.  If you are not interested in
  31           Oops messages from kernel modules, say N.

  38           This is a special uClinux only memory optimization that lets insmod
  39           load the specified kernel module directly into kernel space, reducing
  40           memory usage by preventing the need for two copies of the module
  41           being loaded into memory.

  48           Enabling this, one would be able to get a load map
  49           output on stdout. This makes kernel module debugging
  50           easier.

  52           don't need this option.

 102           This is a WIP, while waiting for a common argument parsing
 103           common amongst all BB applets (shell, modprobe, etc...) and
 104           adds around 600 bytes on x86, 700 bytes on ARM. The code is
 105           biggish and uggly, but just works.

 107           Saying Y here is not a bad idea if you're not that short
 108           on storage capacity.

 129           Support checking for tainted modules.  These are usually binary
 130           only modules that will make the linux-kernel list ignore your
 131           support request.
 132           This option is required to support GPLONLY modules.
