Decrease the SECTION_SIZE_BITS --> MAX_PHYSADDR_BITS range a little bit. The cost of going to SPARSEMEM_STATIC becomes 8K of BSS space, and in return we save a pointer dereferences on every page struct lookup. Even better we hit the main kernel image for the base address which is in a hugepage locked TLB entry. Signed-off-by: David S. Miller <davem@davemloft.net> |
