From: Jan Beulich Date: Thu, 12 Mar 2009 12:09:57 +0000 (+0000) Subject: x86: move a few device initialization objects into .devinit.rodata X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=821508d4ef7920283b960057903505fed609fd16;p=linux-2.6-omap-h63xx.git x86: move a few device initialization objects into .devinit.rodata Impact: debuggability and micro-optimization Putting whatever is possible into the (final) .rodata section increases the likelihood of catching memory corruption bugs early, and reduces false cache line sharing.
