This assumes phys_addr_t == unsigned long long, which is just plain
wrong. I will fix it up, but please take more care with that in the
future. This triggers a warning when building for i386 non-PAE, which
is a good thing because it is a real error.
Also, don't we usually display resources as an *inclusive* range,
meaning that the last one should be base + size - 1?
