Subject: [PATCH] powerpc/ptdump: Fix DEBUG_WX since generic ptdump conversion
Date: Fri,  3 Dec 2021 23:41:12 +1100	[thread overview]
Message-ID: <20211203124112.2912562-1-mpe@ellerman.id.au> (raw)

In note_prot_wx() we bail out without reporting anything if
CONFIG_PPC_DEBUG_WX is disabled.

But CONFIG_PPC_DEBUG_WX was removed in the conversion to generic ptdump,
we now need to use CONFIG_DEBUG_WX instead.

Fixes: e084728393a5 ("powerpc/ptdump: Convert powerpc to GENERIC_PTDUMP")
Cc: stable@vger.kernel.org # v5.15+
