Hi Linus,

This patchset allows the earlyres range allocator to replace bootmem.
We have already pushed slab/slub initialization earlier, so the
earlyres allocator can take up the remaining bootmem allocations.
This reduces the total number of allocators used at different phases
of the x86 boot from 4 to 3 (brk, earlyres, full allocator).

Merge remote branch 'linus/master' into x86/bootmem
ibmphp: Rename add_range() to add_bus_range() to avoid conflict

Yinghai Lu (29):
x86: Move range related operation to one file
x86/pci: Use resource_size_t in update_res
x86/pci: AMD one chain system to use pci read out res
x86/pci: Use u64 instead of size_t in amd_bus.c
x86/pci: Add cap_resource()
x86/pci: Enable pci root res read out for 32bit too
x86: Change range end to start+size
x86: Print out RAM buffer information
x86: Call early_res_to_bootmem one time
x86: Introduce max_early_res and early_res_count
x86: Dynamically increase early_res array size
x86: Make early_node_mem get mem > 4 GB if possible
x86: Only call dma32_reserve_bootmem 64bit !CONFIG_NUMA
x86: Make 64 bit use early_res instead of bootmem before slab
sparsemem: Put usemap for one node together
sparsemem: Put mem map for one node together.
x86: Move bios page reserve early to head32/64.c
x86: Separate early_res related code from e820.c
x86: Add find_early_area_size
x86: Move back find_e820_area to e820.c
early_res: Enhance check_and_double_early_res
x86: Make 32bit support NO_BOOTMEM
Move round_up/down to kernel.h
x86: Add find_fw_memmap_area
core: Move early_res from arch/x86 to kernel/
x86: Fix non-bootmem compilation on PowerPC
early_res: Add free_early_partial()
sparsemem: Fix compilation on PowerPC
early_res: Need to save the allocation name in drop_range_partial()
