[Qemu-devel] [PATCH v2 uq/master 0/2] KVM: issues with XSAVE support

[Paolo Bonzini]

This series fixes two migration bugs concerning KVM's XSAVE ioctls.
The second right now is only a theoretical problem, since the only
XSAVE-specific state is AVX and all machines with XSAVE also have AVX.
In the future, this will ensure that machines with MPX or AVX-512
do not expose those XSAVE states when using e.g. "-cpu SandyBridge".

Please review.
