Re: hypercall via "TRAP_INSTR" vs. hypercall page

If we still use the TRAP_INSTR macro to make a hypercall

Reason: TRAP_INSTR has been removed in xen-unstable which
means Xen versions newer than 4.1 no longer support
this method.

Are you asking to turn off the COMPAT Xen 3.0.1 code for domUs by default?

In any case, I'd like to keep the option available though :)
