* powerpc: Trivially merge several headers from asm-ppc64 to asm-powerpcPaul Mackerras2005-11-19
| | | | | | | | | | | | | | | | For these, I have just done the lame-o merge where the file ends up looking like: #ifndef CONFIG_PPC64 #include <asm-ppc/foo.h> #else ... contents from asm-ppc64/foo.h #endif so nothing has changed, really, except that we reduce include/asm-ppc64 a bit more.

* [PATCH] ppc64: Convert NUMA to sparsemem (3)Anton Blanchard2005-11-11
| | | | | | | | | | | | | | | | Convert to sparsemem and remove all the discontigmem code in the process. This has a few advantages: - The old numa_memory_lookup_table can go away - All the arch specific discontigmem magic can go away We also remove the triple pass of memory properties and instead create a list of per node extents that we iterate through. A final cleanup would be to change our lmb code to store extents per node, then we can reuse that information in the numa code.

* [PATCH] ppc64: prep for NUMA sparsemem rework 2Anton Blanchard2005-11-11
| | | | | | | | Remove ppc64 specific version of nr_cpus_node and use the generic one provided. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] ppc64: prep for NUMA sparsemem reworkAnton Blanchard2005-11-11
| | | | | | | | | | | Remove an unused numa define and move a discontigmem specific define inside the relevant ifdef. I will submit a separate patch to remove them from other architectures, but the ppc64 patches to follow depend on this.

* [PATCH] Memory Add Fixes for ppc64Mike Kravetz2005-11-07
| | | | | | | | | This is a temporary kludge that supports adding all new memory to node 0. I will provide a more complete solution similar to that used for dynamically added CPUs in a few days. Signed-off-by: Mike Kravetz <kravetz@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] memory hotplug prep: kill local_mapnrDave Hansen2005-10-30
| | | | | | | | | | | | | | | The following series implements memory hot-add for ppc64 and i386. There are x86_64 and ia64 implementations that will be submitted shortly as well, through the normal maintainers. This patch: local_mapnr is unused, except for in an alpha header. Keep the alpha one, kill the rest. 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>

* [PATCH] ppc64: add early_pfn_to_nidAndy Whitcroft2005-06-23
| | | | | | | | | | | | Provide an implementation of early_pfn_to_nid for PPC64. This is used by memory models to determine the node from which to take allocations before the memory allocators are fully initialised.

* [PATCH] remove non-DISCONTIG use of pgdat->node_mem_mapDave Hansen2005-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch effectively eliminates direct use of pgdat->node_mem_map outside of the DISCONTIG code. On a flat memory system, these fields aren't currently used, neither are they on a sparsemem system. There was also a node_mem_map(nid) macro on many architectures. Its use along with the use of ->node_mem_map itself was not consistent. It has been removed in favor of two new, more explicit, arch-independent macros: pgdat_page_nr(pgdat, pagenr) nid_page_nr(nid, pagenr) I called them "pgdat" and "nid" because we overload the term "node" to mean "NUMA node", "DISCONTIG node" or "pg_data_t" in very confusing ways. I believe the newer names are much clearer. These macros can be overridden in the sparsemem case with a theoretically slower operation using node_start_pfn and pfn_to_page(), instead. We could make this the only behavior if people want, but I don't want to change too much at once. One thing at a time. This patch removes more code than it adds. Compile tested on alpha, alpha discontig, arm, arm-discontig, i386, i386 generic, NUMAQ, Summit, ppc64, ppc64 discontig, and x86_64.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
