[Qemu-devel] [PATCH 0/7] target-i386: xsave CPUID handling refactor

[Eduardo Habkost]

This series refactor the xsave CPUID handling so it won't
silently disable any XSAVE components on CPUID[0xD] in case the
host doesn't support it. It will instead use the exisitng
check/enforce logic for filtering the CPUID bits and checking for
host-side support.

This series is available on git at:
  https://github.com/ehabkost/qemu-hacks.git work/xsave-cpuid-cleanup

The series is based on my x86-next branch, that contains other
CPUID-related changes:
