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

Masks can be specified using a forward slash, like, for example:

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
