Both AMD SEV and Intel TDX has to decode MMIO instruction to be able to handle MMIO.
Extract insn_decode_mmio() from SEV code. TDX will also use this helper.
v3: - Handle insn_get_opcode() in is_string_insn() v2: - insn_get_modrm_reg_ptr() returns unsigned long pointer now (PeterZ); - Handle insn_get_opcode() failure in insn_decode_mmio() (PeterZ);
Kirill A. Shutemov (4): x86/insn-eval: Handle insn_get_opcode() failure x86/insn-eval: Introduce insn_get_modrm_reg_ptr() x86/insn-eval: Introduce insn_decode_mmio() x86/sev-es: Use insn_decode_mmio() for MMIO implementation
