Very lightly tested (UP i386 laptop with 256MB of RAM). As the patch is too lengthy to post directly, I give only pointers to it. It features two new features: (1) dynamic page stealing (2) free_pages() of higher-order pages for bulk marking of free pages in the buddy allocator bitmap in free_all_bootmem_core(). and a cleanup: (3) various cleanups including codesize reduction and elimination of dozens of include/asm-*/bootmem.h droppings around the tree. Available from: bk://linux-wli.bkbits.net/bootmem/ ftp://ftp.kernel.org/pub/linux/kernel/wli/bootmem/bootmem-2.5.17-1 Remaining TODO items to follow up on are: (1) The ability to mark memory as available at runtime but unusable for bootmem allocations. (rmk) (2) Implement queries for automatic determination of ->node_start_paddr and ->node_low_pfn.
