sparc actually supports gigantic pages and selecting ARCH_HAS_GIGANTIC_PAGE allows it to allocate and free gigantic pages at runtime. sparc allows configuration such as huge pages of 16GB, pages of 8KB and MAX_ORDER = 13 (default): HPAGE_SHIFT (34) - PAGE_SHIFT (13) = 21 >= MAX_ORDER (13) Signed-off-by: Alexandre Ghiti <alex@ghiti.fr>Much better.
