  commit f75b1a5247b3b311d3aa50de4c0e5f2d68085cb1
  Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>
  Date:   Fri May 5 17:01:47 2017 +0100
  
      x86/pv: Drop int80_bounce from struct pv_vcpu
      
      The int80_bounce field of struct pv_vcpu is a bit of an odd special case,
      because it is a simple derivation of trap_ctxt[0x80], which is also 
stored.
      
      It is also the only use of {compat_,}create_bounce_frame() which isn't
      referencing the plain trap_bounce field of struct pv_vcpu.  (And altering 
this
      property the purpose of this patch.)
      
      Remove the int80_bounce field entirely, along with 
init_int80_direct_trap(),
      which in turn requires that the int80_direct_trap() path gain logic 
previously
      contained in init_int80_direct_trap().
      
      This does admittedly make the int80 fastpath slightly longer, but these 
few
      instructions are in the noise compared to the architectural context switch
      overhead, and it now matches the syscall/sysenter paths (which have far 
less
      architectural overhead already).
      
      No behavioural change from the guests point of view.
