[PATCH 0/4] [RFT] cleanup /chosen/linux,stdout-path warning

On arm we get

"Unable to find /proc/device-tree//chosen/linux,stdout-path, printing
from purgatory is diabled"

when loading a kexec kernel. There are three problems with this warning.

 1) two slashes after device-tree
 2) we should be also checking (and firstly) for /chosen/stdout-path,
    as linux,stdout-path is the deprecated node name. We may actually
    have the former on arm, allowing us to avoid this warning all together.
 3) "disabled" has a typo in it

This series addresses these three problems with the last three patches,
and the first patch removes a compiler warning.

I've added the RFT as these patches touch code shared with other
architectures, namely powerpc, but I only tested on arm.

Please keep me on CC, as I'm not subscribed to the kexec mailing list.

Thanks,
drew
