Thread-topic: [Xen-devel] MTRR issue introduced by c/s 17404
Due to c/s 17404 reserves one more special page in build_e820map(), MTRR
can't cover all memory ranges. In order to fix it, need to do relevant
changing in setup_var_mtrrs() which uses magic number to caculate size.
It's the second time this issue occurs. It's better to get rid the magic
number. Thanks!
