x86/insn: Add some Intel instructions to the opcode map
[ Upstream commit b980be189c ]
Add to the opcode map the following instructions:
cldemote
tpause
umonitor
umwait
movdiri
movdir64b
enqcmd
enqcmds
encls
enclu
enclv
pconfig
wbnoinvd
For information about the instructions, refer Intel SDM May 2019
(325462-070US) and Intel Architecture Instruction Set Extensions
May 2019 (319433-037).
The instruction decoding can be tested using the perf tools'
"x86 instruction decoder - new instructions" test as folllows:
