Hi Linus,
Building the origin tree, today's linux-next build (powerpc allyesconfig)
produced this warning:
WARNING: mm/built-in.o(.text.unlikely+0xc22): Section mismatch in reference from the function .new_kmalloc_cache() to the variable .init.rodata:kmalloc_info
The function .new_kmalloc_cache() references
the variable __initconst kmalloc_info.
This is often because .new_kmalloc_cache lacks a __initconst
annotation or the annotation of kmalloc_info is wrong.
Caused by commit a9730fca9946 ("Fix kmalloc slab creation sequence").

Cheers,
Stephen Rothwell sfr@canb.auug.org.au

when I'm talking to journalists I just say "programmer" or something like that.
