The RMPREAD instruction’s definition in the x86 opcode tables incorrectly included a redundant ‘x64’ attribute, as RMPREAD inherently depends on 64-bit operations. This change removes the redundant attribute, aligning the definition with the instruction’s actual requirements and also ensuring consistency with the RMPQUERY instruction. Additionally, the operand-less form of the RMPREAD instruction has been added.
