This patch adds in the necessary support for sparsemem such that x86-64 kernels may use sparsemem as an alternative to discontigmem for NUMA kernels. Note that this does no preclude one from continuing to build NUMA kernels using discontigmem, but merely allows the option to build NUMA kernels with sparsemem. Interestingly, the use of sparsemem in lieu of discontigmem in NUMA kernels results in reduced text size for otherwise equivalent kernels as shown in the example builds below: text data bss dec hex filename 2371036 765884 1237108 4374028 42be0c vmlinux.discontig 2366549 776484 1302772 4445805 43d66d vmlinux.sparse Signed-off-by: Matt Tolentino <matthew.e.tolentino@intel.com> Signed-off-by: Dave Hansen <haveblue@us.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> |
