Message-Id: <1379012038-31764-1-git-send-email-msalter@redhat.com> Date: Thu, 12 Sep 2013 14:53:58 -0400 From: Mark Salter <msalter@...hat.com> To: linux-arch@...r.kernel.org Cc: linux-kernel@...r.kernel.org, rth@...ddle.net, vgupta@...opsys.com, linux@....linux.org.uk, tony.luck@...el.com, geert@...ux-m68k.org, monstr@...str.eu, ralf@...ux-mips.org, jejb@...isc-linux.org, benh@...nel.crashing.org, lethal@...ux-sh.org, davem@...emloft.net, cmetcalf@...era.com, gxt@...c.pku.edu.cn, tglx@...utronix.de, mingo@...hat.com, hpa@...or.com, Mark Salter <msalter@...hat.com> Subject: [PATCH] Kconfig cleanup (PARPORT_PC dependencies) Remove messy dependencies from PARPORT_PC by having it depend on one Kconfig symbol (ARCH_MAY_HAVE_PC_PARPORT) and having architectures which need it declare ARCH_MAY_HAVE_PC_PARPORT in arch/*/Kconfig. New architectures are unlikely to need PARPORT_PC, so this avoids having an ever growing list of architectures to exclude. Those architectures which do declare ARCH_MAY_HAVE_PC_PARPORT in this patch are the ones which have an asm/parport.h.
