[Xen-devel] [PATCH v6 00/21] x86: Improvements to cpuid handling for guests

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

This series is available in git form at:
  http://xenbits.xen.org/git-http/people/andrewcoop/xen.git levelling-v6

Very few changes from v5:
 * Change the PKU feature depdendency from PAE to LM
 * Bugfix for HVM CPUID.0xd[1].ebx when %xcr0 is empty
 * Tweak command line parsing in xen-cpuid to avoid a backwards goto
 * Misc comment improvements

Most importantly, a complete set of Reviews and Acks.

Andrew Cooper (21):
