Subject: [PATCH -next] staging: lustre: Use proper constant types for L*_POISON values

On 32-bit m68k, I get lots of warnings like:

    warning: integer constant is too large for ‘long’ type

Switch the L*_POISON definitions from too-large constants and casts
to the proper constant types to fix this.

The values in drivers/staging/lustre/lustre/include/linux/lustre_lib.h
don't seem to be used, as LP_POISON is already defined at that point?
