[PATCH 00/12] aarch64: Add Armv9.4-A support for the d128 extension

[Victor Do Nascimento]

The d128 extension released as an optional architectural feature for
Armv9.4-a introduces 128-bit page table descriptors and support for
these.

Support is done via 128-bit system registers and instructions to
retrieve and write to these in the form of `mrrs'/`msrr',
respectively, as well as the 128-bit system instruction `sysp' and its
alias `tlbip': TLB Invalidate Pair operation.

This patch series adds the necessary changes for assembly, disassembly
and validation of these operations and their various operands.

Victor Do Nascimento (12):
  aarch64: Add +d128 architectural feature support
  aarch64: Expand maximum number of operands from 5 to 6
  aarch64: Add support for xzr register in register pair operands
  aarch64: Add support for optional operand pairs
  aarch64: Add support for the SYSP 128-bit system instruction
  aarch64: Apply narrowing of allowed immediate values for SYSP
  aarch64: Create QL_SRC_X2 and QL_DEST_X2 qualifier macros
  aarch64: Implement TLBIP 128-bit instruction
  aarch64: Add xs variants of tlbip operands
  aarch64: Add TLBIP tests
  aarch64: Add support for 128-bit system register mrrs and msrr insns
  arch64: Add optional operand register pair support tests
