Help text

On HiSilicon HIP09, TLB entry matching behavior when CNP (TTBRx.CNP=1) is enabled differs from the ARM architecture specification.

TLB entries may be incorrectly shared between CPUs, potentially causing TLB conflicts and stale mappings.

Disable CNP support for affected HiSilicon HIP09 cores.

If unsure, say Y.
