      x86/PV: harden guest memory accesses against speculative abuse
      
      Inspired by
      https://lore.kernel.org/lkml/f12e7d3cecf41b2c29734ea45a393be21d4a8058.1597848273.git.jpoimboe@redhat.com/
      and prior work in that area of x86 Linux, suppress speculation with
      guest specified pointer values by suitably masking the addresses to
      non-canonical space in case they fall into Xen's virtual address range.
      
      Introduce a new Kconfig control.
      
      Note that it is necessary in such code to avoid using "m" kind operands:
      If we didn't, there would be no guarantee that the register passed to
      guest_access_mask_ptr is also the (base) one used for the memory access.
      
      As a minor unrelated change in get_unsafe_asm() the unnecessary "itype"
      parameter gets dropped and the XOR on the fixup path gets changed to be
      a 32-bit one in all cases: This way we avoid pointless REX.W or operand
      size overrides, or writes to partial registers.
