[PATCH] x86/APX: limit printing of REX2 payload
Jan Beulich proposes a patch to the x86 disassembler that limits the printing of REX2 payloads. When REX2 bits are consumed and only indicate the encoding is in use, the output will now simply show ‘{rex2}’ for better matching of original input. The patch also simplifies conditional logic and updates test cases.
