[Xen-devel] [PATCH 0/6] x86/emul: Use struct cpuid_policy for feature checks

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Prompted by Jan's "x86emul: consolidate CR4 handling", I've cleaned up this
series and posted it.  The end purpose is the substantial reduction in
compiled volume of x86_emulate().

Andrew Cooper (6):
  tools: Move the typesafe min/max helpers into xen-tools/libs.h
  libx86: Split x86_cpuid_policy_fill_native() out of calculate_raw_policy()
  tools/x86emul: Use struct cpuid_policy in the userspace test harnesses
  x86/emul: Pass a full cpuid_policy into x86_emulate()
  x86/emul: Don't use the ->cpuid() hook for feature checks
  x86/emul: dedup hvmemul_cpuid() and pv_emul_cpuid()
