After applying this patch, I get

(0x000000000000814c is not between 0xffffffffffff8000 and 0x0000000000007ffc)

with powerpc:defconfig, powerpc:allmodconfig, powerpc:cell_defconfig, and
powerpc:maple_defconfig.

This is on top of v3.15-rc5. Any idea what is going on ?

Compiler is powerpc64-poky-linux-gcc (GCC) 4.7.2 (from poky 1.4.0-1).

Interesting... works with all my test configs using 4.7.3...

I don't have my tree at hand right now, I'll check what that means
tomorrow see if I can find a workaround.

It works for me with gcc 4.8.2 (build from yocto 1.6.0).

Is asking people to use gcc 4.7.3 or later acceptable ?
