Subject: [PATCHv6 01/11] lib/Kconfig.debug: Add ARCH_HAS_DEBUG_VIRTUAL
Date: Tue, 3 Jan 2017 09:21:43 -0800 [thread overview]
Message-ID: <1483464113-1587-2-git-send-email-labbott@redhat.com> (raw)
In-Reply-To: <1483464113-1587-1-git-send-email-labbott@redhat.com>
DEBUG_VIRTUAL currently depends on DEBUG_KERNEL && X86. arm64 is getting
the same support. Rather than add a list of architectures, switch this
to ARCH_HAS_DEBUG_VIRTUAL and let architectures select it as
appropriate.

Enable some costly sanity checks in virtual to page code. This can
catch mistakes with virt_to_page() and friends.
