[PATCH] Fix exclusion range in find_vmemmap_pages()
In the function, since pfn ranges are literally start and end, not start
and end+1, if the struct page of endpfn is at the last in a vmemmap page,
the vmemmap page is dropped by the following code, and not excluded.
npfns_offset = endpfn - vmapp->rep_pfn_start;
vmemmap_offset = npfns_offset * size_table.page;
// round down to page boundary
vmemmap_offset -= (vmemmap_offset % pagesize);
We can use (endpfn+1) here to fix.
