applied, thanks Yinghai.

i've picked up the following patches from you into a new 
tip/x86/setup-memory topic:

Yinghai Lu (19):
      x86: check command line when CONFIG_X86_MPPARSE is not set, v2
      x86: clean up init_amd()
      x86: remove some acpi ifdefs in setup_32/64
      x86: seperate funcs from setup_64 to cpu common_64.c
      x86: change identify_cpu to static
      x86: add e820_remove_range
      x86: seperate probe_roms into another file
      x86: merge setup64.c into common_64.c
      x86: remove two duplicated funcs in setup_32.c
      x86: move reserve_standard_io_resource to setup.c
      x86: move elfcorehdr parsing to setup.c
      x86: introduce initmem_init for 64 bit
      x86: introduce initmem_init for 32 bit
      x86: introduce reserve_initrd
      x86: move boot_params declaring to setup.c
      x86: move find_max_low_pfn to init_32.c
      x86: move reservetop and vmalloc parsing to pgtable_32.c
      x86: clean up using max_low_pfn on 32-bit
      x86: clean up min_low_pfn

very nice stuff - and it's working pretty well in my testing so far!
