16.3.6 badram
-------------

 -- Command: badram addr,mask[,addr,mask...]
     Filter out bad RAM.

   This command notifies the memory manager that specified regions of
RAM ought to be filtered out (usually, because they're damaged).  This
remains in effect after a payload kernel has been loaded by GRUB, as
long as the loaded kernel obtains its memory map from GRUB. Kernels that
support this include Linux, GNU Mach, the kernel of FreeBSD and
Multiboot kernels in general.

   Syntax is the same as provided by the Memtest86+ utility
(http://www.memtest.org/): a list of address/mask pairs.  Given a
page-aligned address and a base address / mask pair, if all the bits of
the page-aligned address that are enabled by the mask match with the
base address, it means this page is to be filtered.  This syntax makes
it easy to represent patterns that are often result of memory damage,
due to physical distribution of memory cells.
