[PATCH 0/4] mm: add missing MODULE_DESCRIPTION() macros

[PATCH 0/4] mm: add missing MODULE_DESCRIPTION() macros

[Jeff Johnson]

This fixes the instances of "WARNING: modpost: missing
MODULE_DESCRIPTION()" that I'm seeing in 'mm'.

Note I'm not using an "everything enabled" configuration so there may
be more left to fix.

I guess this warning has been there since the beginning, we just never
compiled this module with W=1.
