Currently we have some ad-hoc code in x86.c to restrict #UD emulation to
expected instructions (that is, vendor specific instructions). This patchset
replaces the ad-hoc code with proper emulator support using decode tables.
Avi Kivity (3):
KVM: Drop bogus x86_decode_insn() error check
v2: replaces v1's first two patches
KVM: x86 emulator: vendor specific instructions
KVM: Drop ad-hoc vendor specific instruction restriction
v3: preserve early-exit on #UD (reexecute_instruction() isn't reliable
since we don't have a valid cr2)
