Subject: [PATCHv2 1/6] lib/Kconfig.debug: Add ARCH_HAS_DEBUG_VIRTUAL
Date: Wed, 2 Nov 2016 15:00:49 -0600 [thread overview]
Message-ID: <20161102210054.16621-2-labbott@redhat.com> (raw)
In-Reply-To: <20161102210054.16621-1-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.
Suggested-by: Mark Rutland <mark.rutland@arm.com>

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