David S. Miller	4e286d5be6	[SPARC64]: MAX_PHYSADDR_BITS et al. really need to be 42 bits not 41. ... Signed-off-by: David S. Miller <davem@davemloft.net>	18 years ago
David S. Miller	d78d0891d3	[SPARC64]: Use SPARSEMEM_STATIC ... 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>	18 years ago
David S. Miller	d1112018b4	[SPARC64]: Move over to sparsemem. ... This has been pending for a long time, and the fact that we waste a ton of ram on some configurations kind of pushed things over the edge. Signed-off-by: David S. Miller <davem@davemloft.net>	19 years ago
