What's in sh-2.6.23.git

Now that 2.6.22 is winding down, it's time to review what's going on for the 2.6.23 merge window. The big changes so far are mostly centered around NUMA and sparsemem support, rework of the IRQ controllers and the machvec, as well as some Kconfig reordering (we're now in much better shape to survive allyesconfig/allmodconfig/randconfig for regression testing). There's quite a bit of SMP code also, for 4-way SH-X3, so some of that will make it in, with most of the later 2.6.23-rc's then being targetted at fixing up a lot of the remaining locking issues and so on. multi-node NUMA is presently only wired up on SH-MobileR (SH7722), particularly its URAM block (128kB SRAM), but SH7785 and others will follow, all the way up to 6-nodes for SH-X3. There'll be some documentation on the wiki a bit later on how to work with it, for those that are interested. There are a couple outstanding patches required to make use of this, including changing the node interleave map for kernel data structure spreading at system init time, which can be found here: http://marc.info/?l=linux-mm&m=118117916022379&w=2 and either SLUB + http://marc.info/?l=linux-mm&m=118127614524083&w=2, or SLOB + http://marc.info/?l=linux-mm&m=118213456808163&w=2 SLAB is also possible, but is quite heavy on the non-reclaimable slab pages, so is better avoided for tiny nodes. cpusets + page migration is also possible, but with a node this small, page migration is best avoided. Simply mounting the node with a mempolicy via tmpfs or using libnuma is the best way for applications to make use of the memory (remember that URAM access bypasses the cache controller!). The outstanding patches should also be merged during the -rc1 window, via alternate channels.
