Subject: [PATCH] drivers/base/node.c: fix compilation error

Hi all,

	the current mainline kernel gives a "directives may not be used
inside a macro argument" error message when compiled for the
cris architecture.

It happened for the /fs/proc/meminfo.c file, for which a patch has been
already sent to LKML.

It happens for drivers/base/node.c too. The patch below fixes the
problem.

Best regards,

	Claudio
