Subject: [PATCH v1 0/3] param: configurable /sys/module/*/paramaters

These changes allow to compile kernels with sysfs but without
/sys/module/*/paramaters/. This should allow:
 - on small systems: no memory pressure caused by unneeded sysfs
   attributes.
 - on large systems: more modules could be converted to have their
   perm != 0 in module_param(): better for audit, debug, etc. For
   example, on my copy, 1658 module attributes have perm == 0,
   presumably to spare some memory, but it can be interesting to have
   access to those at runtime.

By default, /sys/module/*/paramaters/ is enabled, but can be disabled
in expert mode (CONFIG_SYSFS_MODULE_PARAM is not set).

David Decotigny (3):
  param: make destroy_params() private
  param: simple refactoring
  param: allow to selectively enable /sys/module/MOD/paramaters nodes
