That's the second time the robot reports sparse errors on that commit,
but the only thing I did is move code, that commit didn't add any code,
so I don't know what I should do about it.

Hi Christophe,
Yes, these sparse warnings not introduced by this commit.
Please ignore them. Sorry for the noise.
These warnings were treated as new warning because the file name changed (arch/powerpc/kernel/machine_kexec.c --> arch/powerpc/kexec/core.c)
We will look for solution to resolve such kind of false positive. Thanks.
