[PATCH] xen: x86: Rename usermode macro

Browse Source 
Rename user_mode to user_mode_vm and add a user_mode macro similar to the
x86-64 one.

This is useful for Xen because the linux xen kernel does not runs on the same
priviledge that a vanilla linux kernel, and with this we just need to redefine
user_mode().
