>    [PATCH] xen: x86_64: use more usermode macro
>
>    Make use of the user_mode macro where it's possible.  This is useful for Xen
>    because it will need only to redefine only the macro to a hypervisor call.

I am of the opinion that the above changeset is incomplete, i.e.  it missed
converting some previous uses of user_mode to user_mode_vm.  While most of
them could be considered just cosmetical, at least the one in die_nmi
doesn't appear to be.
