Build failure in v4.4.y.queue (ppc:allmodconfig)

[Guenter Roeck]

I see multiple instances of:

arch/powerpc/kernel/exceptions-64s.S:839: Error:
	attempt to move .org backwards

in v4.4.y.queue (v4.4.179-143-gc4db218e9451).

This is due to commit 9b2d4e06d7f1 ("powerpc/64s: Add support for a store
forwarding barrier at kernel entry/exit"), which is part of a large patch
series and can not easily be reverted.

Guess I'll stop doing ppc:allmodconfig builds in v4.4.y ?

Thanks,
Guenter
