[PATCH v2 0/4] XEN: fix vmx exception mistake
Changes from v1:
- Define new struct hvm_trap to represent information of trap, include
instruction length.
- Renames hvm_inject_exception to hvm_inject_trap. Then define a couple of
wrappers around that function for existing callers, so that their parameter
lists actually *shrink*.
This series of patches fix the mistake for debug exception(#DB), overflow
exception(#OF) and INT3(#BP),

This series of patches fix the mistake for debug exception(#DB), overflow
exception(#OF) and INT3(#BP), INTn instruction emulation.
Introduce new function vmx_inject_sw_exception() which deliver the software
excetion, software interrupt and privileged software exception. Split hardware
exception as a seperate function(old function vmx_inject_hw_exception()).
Also Passed down intruction length
