Changes from V1: * Add note to HOWTO that the HEAPBASE option is not used with THP morecore * Change warning in thp_morecore to more accurately reflect the problem discovered
Transparent huge pages (THP) make using huge pages on x86(_64) incredibly easy. However, the standard glibc malloc is not setup to optimixe allocations to be fulfilled as THP, relying on khugepaged to scan and merge huge pages when possible. This patch set extends the morecore idea that was originally used to back the heap with hugetlbfs huge pages to ensure that the heap is grown in huge page sized increments. This allows the kernel allocator to start the new area as a huge page rather than wait for promotion.
