Hi Andrew,

After merging the akpm tree, today's linux-next build (powerpc
allyesconfig) failed like this:

In file included from arch/powerpc/include/asm/paca.h:19:0,

include/linux/string.h:305:4: error: call to '__read_overflow2' declared with attribute error: detected read beyond size of object passed as 2nd parameter

I don't know why this has turned up now. I have just left it broken
for now and would appreciate any fix.
