Subject: [PATCH 13/16] perf kvm/{x86,s390}: Remove const from kvm_events_tp

See http://www.infradead.org/rpr.html

From: Hemant Kumar <hemant@...ux.vnet.ibm.com>

This patch removes the "const" qualifier from kvm_events_tp declaration
to account for the fact that some architectures may need to update this
variable dynamically. For instance, powerpc will need to update this
variable dynamically depending on the machine type.
