[PATCH] Fix SRAT check for discontig memory
We currently compare the sum of the pages found in the SRAT table to the
address of the highest memory page found via the e820 table to validate
the SRAT. This is completely bogus if there''s any kind of discontiguous
memory, where the sum of the pages could be much smaller than the
address of the highest page. I think all that''s necessary is to
validate that each usable memory
