The current "badpage" boot option only allows you to select
individual pages, which is not an option for me, since I have
close to 32M of bad ram. My patch allows the use of masks
to select many pages at once, much like the linux BADRAM
patch.

Masks can be specified using a forward slash, like, for example:
badpage=0xa2000/0xef000,0x00100/0xfff00,0x01000

The masking scheme is unnecessarily restrictive. Why not just allow specification of inclusive ranges of pages? For example: badpage=0xa2000-0xa2fff,0x100-0x1ff,0x123-0x456
