The following four patches provide the last needed changes before the introduction of sparsemem. For a more complete description of what this will do, please see this patch: http://www.sr71.net/patches/2.6.11/2.6.11-bk7-mhp1/broken-out/B-sparse-150-sparsemem.patch or previous posts on the subject: http://marc.theaimsgroup.com/?t=110868540700001&r=1&w=2 http://marc.theaimsgroup.com/?l=linux-mm&m=109897373315016&w=2 Three of these are i386-only, but one of them reorganizes the macros used to manage the space in page->flags, and will affect all platforms. There are analogous patches to the i386 ones for ppc64, ia64, and x86_64, but those will be submitted by the normal arch maintainers. The combination of the four patches has been test-booted on a variety of i386 hardware, and compiled for ppc64, i386, and x86-64 with about 17 different .configs. It's also been runtime-tested on ia64 configs (with more patches on top). This patch: We _know_ which node pages in general belong to, at least at a very gross level in node_{start,end}_pfn[]. Use those to target the allocations of pages.
