		<description><![CDATA[This email from Ingo Molnar gives a simple introduction on how to use pref on an x86 to gain information on system performance.
Do you have an x86 box to test it on?
If yes then perfcounters can be used for _much_ more precise

First it complains about version the protobuf code was using automake 1.10.1 and I had 1.7.9. so I upgraded to automake using &#8220;sudo apt-get install automake1.10&#8243;. Of course this upgraded my automake to 1.10.2 which still didn&#8217;t work.The solution was to run autoconf from [...]]]></description>

		<description><![CDATA[Today learned some things about git and applying patches. First when applying my trec/ace/kshmem patches to 2.6.25-rc2 they wouldn&#8217;t apply because now there only an x86 architecture (arch/x86) instead of two architectures i386 and x86_64. That was to be expected actually and there&#8217;s going to be some hand work in doing that.
