* [SPARC64]: MAX_PHYSADDR_BITS et al. really need to be 42 bits not 41.David S. Miller2007-04-261-2/+2

* [SPARC64]: Use SPARSEMEM_STATICDavid S. Miller2007-04-261-3/+3
| | | | | | | | | | | | 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>
* [SPARC64]: Move over to sparsemem.David S. Miller2006-03-201-0/+12
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>
