From mboxrd@z Thu Jan 1 00:00:00 1970 From: labbott@redhat.com (Laura Abbott) Date: Wed, 2 Nov 2016 15:00:49 -0600 Subject: [PATCHv2 1/6] lib/Kconfig.debug: Add ARCH_HAS_DEBUG_VIRTUAL In-Reply-To: <20161102210054.16621-1-labbott@redhat.com> References: <20161102210054.16621-1-labbott@redhat.com> Message-ID: <20161102210054.16621-2-labbott@redhat.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
