From: Andrew Pinski
Date: Wed Jan 13 2016 - 02:09:27 EST


This is version 2. I expanded it to include copy_template as it was a simple
extension to the new version of the patch.
Changes since v1:
1) Add infastructure for checking MIDR for features
2) Use the copy_page version from Will Deacon
3) Add prefetching feature
4) Add prefetching to copy_page
5) Add prefetching to copy_template


Andrew Pinski (5):
ARM64: Support midr detected cpufeature
ARM64 Improve copy_page for 128 byte cache line
ARM64: Add Needs software prefetching cap
ARM64: Patch in prefetching for copy_page is requested
ARM64: Patch in prefetching in copy_template
