[PATCH v10 11/38] x86/opcode: Add ERET[US] instructions to the x86 opcode map

[Xin Li <xin3.li@xxxxxxxxx>]

From: "H. Peter Anvin (Intel)" <hpa@xxxxxxxxx>

ERETU returns from an event handler while making a transition to ring 3,
and ERETS returns from an event handler while staying in ring 0.

Add instruction opcodes used by ERET[US] to the x86 opcode map; opcode
numbers are per FRED spec v5.0.
