Re: [PATCH v3 6/7] aarch64: Remove +mpamv2 feature option
This patch series proposes removing the +mpamv2 feature option for the aarch64 architecture in binutils. The change is motivated by the fact that MPAMv2 related details now only use system registers and are no longer controlled by a specific feature option, with MPAMv2 becoming optional from Armv9.3-a. The author clarifies a potential typo and explains the rationale behind the change.
