[richard.ball@arm.com]

From: Richard Ball <Richard.Ball@arm.com>

This patch series adds support for FEAT_MPAMv2_VID
This patch requires: https://inbox.sourceware.org/binutils/20260115163056.72370-1-Ezra.Sitorus@arm.com/T/#u

========================================================================
[1/2] aarch64: Add FEAT_MPAMv2_VID system registers

This patch adds the system registers defined by
FEAT_MPAMv2_VID. These registers are:

   *mpamvidcr_el2
   *mpamvidsr_el2
   *mpamvidsr_el3


========================================================================
[2/2] aarch64: Add support for MLBI system instructions

This patch adds support for MLB invalidate operation (MLBI) instruction
and the corresponding system registers as operand (<mlbi_op>).

Syntax: MLBI <mlbi_op>{, <Xt>}

This instruction is an alias to "SYS #4, C7, C0, #<op2>{, <Xt>}"
and MLBI being the preferred disassembly.

The following list of system registers are supported in this patch for the
MLBI instructions enabled by "+mpamv2"

   * alle1
   * vmalle1
   * vpide1
   * vpmge1
