If the bitmap is used to represent domU pages, the amount of memory is
limited to 8TB due to the 32bit value. Adjust the code to use 64bit
values as input. All callers already use some form of 64bit as input,
so no further adjustment is required.

Hi all,
We have our answer in regards to getting away from "master" as default
branch name. GitHub will default to "main" from Oct 1.

Cheers,
