From the submitter:
CPU_WT_ALLOC does not work correctly for K6-2s of model 8+ and
probably K6-3s (when they appear on the market soon). In addition,
print_AMD_info() incorrectly printfs write allocation's size. I've
fixed them, so they now Do The Right Thing, and added a
"NO_MEMORY_HOLE" option to easily allow 15-16mb range handling for us
K6 and K6-2 users.
