KVM: x86: Expose XSAVEERPTR to the guest I was surprised to see that the guest reported `fxsave_leak' while the host did not. After digging deeper I noticed that the bits are simply masked out during enumeration. The XSAVEERPTR feature is actually a bug fix on AMD which means the kernel can disable a workaround. Pass XSAVEERPTR to the guest if available on the host. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
