[Joao Martins <joao.m.martins@xxxxxxxxxx>]

Add TSC as another clocksource that can be used, plus
a mention to the maxcpus parameter and that it requires
being explicitly set.

 If set, override Xen's default choice for the platform timer.
+Having TSC as platform timer requires being explicitly set.
+This is because TSC can only be safely used if CPU hotplug isn't performed on
+the system. In some platforms, "maxcpus" parameter may require further
+adjustment to the number of online cpus.
