xsa123-4.3-4.2.patch from upstream:
x86emul: fully ignore segment override for register-only operations
For ModRM encoded instructions with register operands we must not
overwrite ea.mem.seg (if a - bogus in that case - segment override was
present) as it aliases with ea.reg.
This is CVE-2015-2151 / XSA-123.
