<p>For <code>perfevent</code>,
try all combinations of disabling exclude-kernel and disabling exclude-hv,
to handle platforms where cycle counters cannot handle one or both of those.</p>
<p>For <code>perfevent</code>,
do <code>DISABLE</code> and <code>ENABLE</code> around counter read (suggested by Jim Apple)
to (hopefully) handle Graviton 3.
But skip this if a setup test seems to work without it.</p>
<p>Recognize <code>sun4v</code> as <code>sparc64</code>.</p>
<p>Add support for <code>loong64</code>.</p>
<p>Eliminate various compiler warnings.</p>
<p>For <code>cpucycles-info</code>,
print interquartile mean (iqm) rather than median.</p>
<p>Say "sometimes" in documentation for enabling cycle counters in ARM via kernel modules.</p>
<p>Change HTML style, in particular for better usability on phones.</p>
