Subject: mm: make DEBUG_WX depdendent on GENERIC_PTDUMP
Date: Mon, 17 Feb 2025 09:52:19 +0530
DEBUG_WX selects PTDUMP_CORE without even ensuring that the given platform
implements GENERIC_PTDUMP. This problem has been latent until now, as all
the platforms subscribing ARCH_HAS_DEBUG_WX also subscribe GENERIC_PTDUMP.
