[Xen-devel] Xen 4.0 is broken on 32bit

["Huang2, Wei" <Wei.Huang2@xxxxxxx>]

The changset 21229 breaks Xen 4.0.1 tree on 32bit environment. Starting a guest VM will throw out an error as “Error: (38, ‘Function not implemented’)”. Apparently, the hypercall to mem_sharing_op is missing for 32bit environment due to 21229.  The following small patch can fix this issue.

 

Thanks,

-Wei
