commit 5638bd722a44bbe97c1a7b3fae5b9efddb3e70ff upstream.
topa_entry->base needs to store a pfn. It obviously needs to be
large enough to store the largest possible x86 pfn which is
MAXPHYADDR-PAGE_SIZE (52-12). So it is 4 bits too small.
Increase the size of topa_entry->base from 36 bits to 40 bits.
Note, systems where physical addresses can be 256TiB or more are affected.
