From: Doug Goldstein Date: Wed, 24 Feb 2016 11:06:28 +0000 (+0100) Subject: xenoprof: drop unnecessary macro X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=47f3d3fa6dc77f47ac6b4d992f560ef82b714220;p=people%2Fliuw%2Fxen.git xenoprof: drop unnecessary macro This macro doesn't really provide a benefit. When support is added the implementer can implement this how it needs to be and not conform to the macro. Additionally this change limits the output of the warning to just once instead of nrpages worth. While editing this area I dropped trailing whitespace.
