Hi Rob,

I love your patch! Perhaps something to improve:

[also build test WARNING on v4.19-rc1 next-20180831]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

base:   https://git.kernel.org/pub/scm/linux/kernel/git/robh/linux.git for-next
config: i386-allmodconfig (attached as .config)
compiler: gcc-7 (Debian 7.3.0-16) 7.3.0
reproduce:
        # save the attached .config to linux build tree
        make ARCH=i386 

All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.text+0x718907): Section mismatch in reference from the function of_fdt_limit_memory() to the variable .init.data:dt_root_addr_cells
   The function of_fdt_limit_memory() references
   the variable __initdata dt_root_addr_cells.
   This is often because of_fdt_limit_memory lacks a __initdata
   annotation or the annotation of dt_root_addr_cells is wrong.
