Regression: compile error on mpc83xx

[Radu Rendec]

Hi everyone,

I'm getting the following compile error for mpc83xx in v4.9.115:

arch/powerpc/sysdev/built-in.o: In function `fsl_of_msi_probe':
fsl_msi.c:(.text+0x1548): undefined reference to `fsl_mpic_primary_get_version'

This seems to have been fixed in v3.12-rc1 by commit df1024ad8728. Then,
somewhere between v4.0 and v4.1 the following two commits changed the
arch/powerpc/include/asm/mpic.h file and that function again:
5e86bfde9cd9
807d38b73b63

After those two commits, it seems we're back to square one. I haven't
tested, but it looks like there haven't been any other changes to that
file up to the latest master in Linus' tree, so I believe the problem is
still there in the latest kernel.

Should commit df1024ad8728 be reapplied?

Thanks,
Radu Rendec
