Subject: [PATCH] [POWERPC] Add machine initcall macros
Date: Fri, 30 Nov 2007 17:24:56 -0700 [thread overview]
Message-ID: <20071201002437.22923.31304.stgit@trillian.secretlab.ca> (raw)
From: Grant Likely <grant.likely@secretlab.ca>
The machine initcall macros allow initcalls to be registered which
test machine_is() before executing the initcall.
