From: Jeremy Linton
Date: Fri Apr 08 2016 - 17:57:18 EST
Enable ARM performance monitoring units on ACPI/arm64 machines.
This patch expands and reworks the patches published by Mark Salter
in order to clean up a few of the previous review comments, as well as
add support for A72's and big/little configurations.
I've been testing this patch in convert with an assortment of ACPI
patches to enable things like PCIe. Its been tested on juno, seattle
and some xgene systems.
Thanks,
