[Xen-devel] [PATCH RFC v12 03/21] Remove an unnecessary assert from vmx_update_debug_state

[George Dunlap <george.dunlap@xxxxxxxxxxxxx>]

As far as I can tell, there's nothing here that requires v to be
current.  vmx_update_exception_bitmap() is updated in other situations
where v!=current.

Removing this allows the PVH code to call this during vmcs
construction in a later patch, making the code more robust by removing
duplicate code.
