[Xen-devel] [V1 PATCH 1/5] PVH xen tools: Elf and header change.

[Mukesh Rathor <mukesh.rathor@xxxxxxxxxx>]

 Add XENFEAT_hvm_callback_vector to elf_xen_feature_names
 so we can ensure the kernel supports all features requird for 
 PVH mode. Note, hvm callback is required for PVH. 
 Also, introduce _XEN_DOMINF_pvh_guest.
