Subsystem:
arm64 port (aarch64 architecture), kernel virtual machine for arm64 (kvm/arm64), the rest · Maintainers:
Catalin Marinas, Will Deacon, Marc Zyngier, Oliver Upton, Linus Torvalds
Now that we have common definitions for the encoding of Set/Way cache maintenance operations, make the KVM code use these, simplifying the sys_reg_descs table.
