[PATCH v2] Only call ppc_md.setup_arch() if it is provided.
From: Grant Likely <hidden>
Date: 2007-10-08 20:59:02
Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Linus Torvalds
From: Grant Likely <redacted> This allows platforms which don't have anything to do at setup_arch time (like a bunch of the 4xx platforms) to eliminate an empty setup_arch hook.
