The UnholdMemory function makes eligible for paging again a portion of the

address is the start address of the range of memory that is to be let

go.

count is the size in bytes of that range.

page boundary. Similarly, if the specified range does not end on a page

boundary, the count parameter is rounded up so that the entire range of

memory is let go.
