Merge branch 'core-memblock-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'core-memblock-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (74 commits) x86-64: Only set max_pfn_mapped to 512 MiB if we enter via head_64.S xen: Cope with unmapped pages when initializing kernel pagetable memblock, bootmem: Round pfn properly for memory and reserved regions memblock: Annotate memblock functions with __init_memblock memblock: Allow memblock_init to be called early memblock/arm: Fix memblock_region_is_memory() typo x86, memblock: Remove __memblock_x86_find_in_range_size() memblock: Fix wraparound in find_region() x86-32, memblock: Make add_highpages honor early reserved ranges x86, memblock: Fix crashkernel allocation arm, memblock: Fix the sparsemem build memblock: Fix section mismatch warnings powerpc, memblock: Fix memblock API change fallout memblock, microblaze: Fix memblock API change fallout x86: Remove old bootmem code x86, memblock: Use memblock_memory_size()/memblock_free_memory_size() to get correct dma_reserve x86: Remove not used early_res code x86, memblock: Replace e820_/_early string with memblock_ x86: Use memblock to replace early_res x86, memblock: Use memblock_debug to control debug message print out ... Fix up trivial conflicts in arch/x86/kernel/setup.c and kernel/Makefile
