[PATCH 5.4 165/168] powerpc/kuap: PPC_KUAP_DEBUG should depend on PPC_KUAP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Michael Ellerman <mpe@xxxxxxxxxxxxxx>

commit 61da50b76b62fd815aa82d853bf82bf4f69568f5 upstream.

Currently you can enable PPC_KUAP_DEBUG when PPC_KUAP is disabled,
even though the former has not effect without the latter.

Fix it so that PPC_KUAP_DEBUG can only be enabled when PPC_KUAP is
enabled, not when the platform could support KUAP (PPC_HAVE_KUAP).
