Hi Michal,

After merging the kbuild tree, today's linux-next build (powerpc
ppc64_defconfig) produced these warnings:

WARNING: 25 bad relocations
c000000000cf2570 R_PPC64_ADDR64    __crc___arch_hweight16

[...]

Introduced by commit

  9445aa1a3062 ("ppc: move exports to definitions")

I have reverted that commit for today.

[cc-ing the ppc guys for clues - also involved is commit

  22823ab419d8 ("EXPORT_SYMBOL() for asm")
]

FWIW, I see these warnings as well. Any help from ppc developers is
appreciated - should the R_PPC64_ADDR64 be whitelisted for exported asm
symbols (their CRCs actually)?

Thanks,
Michal
