Subject: [PATCHv2 0/4] ARM64: Improve copy_page and copy_template for ThunderX

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
