Raw Normal View History

Linux-2.6.12-rc2 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!

[PATCH] ppc64: Convert NUMA to sparsemem (3) 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] Memory Add Fixes for ppc64 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.
