[kvm-unit-tests,v1,2/4] lib/alloc_page: change some parameter types

Commit Message

Claudio Imbrenda July 3, 2020, 11:51 a.m. UTC

For size parameters, size_t is probably semantically more appropriate
than unsigned long (although they map to the same value).

For order, unsigned long is just too big. Also, get_order returns an
unsigned int anyway.
