Thread-topic: SMAP/SMEP issues with 32-bit pv guests

Hi Andy,

As you know, SMAP/SMEP may affect the 32-bit pv guests, after discussed 
internally, our current idea is that we can just disable this two feature for 
Xen hypervisor itself, hence only enable it for HVM guests. Do you think this 
is acceptable from your perspective?

Thanks,
Feng
