Subject: [PATCH AUTOSEL 5.5 445/542] powerpc/ptdump: Only enable PPC_CHECK_WX with STRICT_KERNEL_RWX
Date: Fri, 14 Feb 2020 10:47:17 -0500 [thread overview]
Message-ID: <20200214154854.6746-445-sashal@kernel.org> (raw)
In-Reply-To: <20200214154854.6746-1-sashal@kernel.org>
From: Christophe Leroy <christophe.leroy@c-s.fr>
[ Upstream commit f509247b08f2dcf7754d9ed85ad69a7972aa132b ]
ptdump_check_wx() is called from mark_rodata_ro() which only exists
when CONFIG_STRICT_KERNEL_RWX is selected.
