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] kdump: Retrieve saved max pfn This patch retrieves the max_pfn being used by previous kernel and stores it in a safe location (saved_max_pfn) before it is overwritten due to user defined memory map. This pfn is used to make sure that user does not try to read the physical memory beyond saved_max_pfn.

[PATCH] for_each_online_pgdat: for_each_bootmem Add a list_head to bootmem_data_t and make bootmems use it. bootmem list is sorted by node_boot_start. Only nodes against which init_bootmem() is called are linked to the list. (i386 allocates bootmem only from one node(0) not from all online nodes.) A summary: 1. for_each_online_pgdat() traverses all *online* nodes. 2. alloc_bootmem() allocates memory only from initialized-for-bootmem nodes.

[PATCH] FRV: Fix FRV arch compile errors Fix some FRV arch compile errors, including: (*) Marking nr_kernel_pages as __meminitdata so that references to it end up being properly calculated rather than being assumed to be in the small data section (and thus calculated wrt the GP register). Not doing this causes the linker to emit errors as the offset is too big to fit into the load instruction. (*) Move pm_power_off into an unconditionally compiled .c file as it's now unconditionally accessed.
