Description
Using GenAlignment as the page size like this is wrong:
os::trace_page_sizes("Heap",
MinHeapSize,
reserved_heap_size,
GenAlignment,
heap_rs.base(),
heap_rs.size());
We should instead pass in the correct "os" page size used. It might make sense to add some additional log that logs the different alignments used by parallel, because I think this is the only place the GenAlignment is printed.
