From: Phil Carmody Date: Tue, 14 Sep 2010 20:34:43 +0000 (-0700) Subject: [IA64] unwind: remove preprocesser noise, and correct comment X-Git-Tag: upstream/snapshot3+hdmi~12730^2^5~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=747584be04bb98a856bab5cd1bfe56d341881b83;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git [IA64] unwind: remove preprocesser noise, and correct comment The expression in the comment was mis-bracketted. There was also no need to introduce a coding-style breaking macro for a single use, so just made it a static const.
