Hi all,

After merging the powerpc tree, today's linux-next build (powerpc64
allnoconfig) failed like this:

WARNING: vmlinux.o(.text+0x12e34): Section mismatch in reference from the function .setup_rfi_flush() to the function .init.text:.ppc64_bolted_size()
The function .setup_rfi_flush() references
the function __init .ppc64_bolted_size().
This is often because .setup_rfi_flush lacks a __init 
annotation or the annotation of .ppc64_bolted_size is wrong.

WARNING: vmlinux.o(.text+0x12e64): Section mismatch in reference from the function .setup_rfi_flush() to the function .init.text:.memblock_alloc_base()
The function .setup_rfi_flush() references
the function __init .memblock_alloc_base().
This is often because .setup_rfi_flush lacks a __init 
annotation or the annotation of .memblock_alloc_base is wrong.

FATAL: modpost: Section mismatches detected.
Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them.

Caused by commit

  abf110f3e1ce ("powerpc/rfi-flush: Make it possible to call setup_rfi_flush() again")

I have left it broken for now.
