Message-ID: <alpine.DEB.2.00.1101261913400.7809@chino.kir.corp.google.com> Date: Wed, 26 Jan 2011 19:14:51 -0800 (PST) From: David Rientjes <rientjes@...gle.com> To: Andrew Morton <akpm@...ux-foundation.org>, Ingo Molnar <mingo@...hat.com>, "H. Peter Anvin" <hpa@...or.com>, Thomas Gleixner <tglx@...utronix.de> cc: Adam Belay <abelay@....edu>, Bjorn Helgaas <bjorn.helgaas@...com>, Russell King <linux@....linux.org.uk>, x86@...nel.org, linux-kernel@...r.kernel.org Subject: [patch 3/4] x86: only compile floppy driver if CONFIG_ISA_DMA_API is enabled The generic floppy disk driver utilizies the interface provided by CONFIG_ISA_DMA_API, specifically claim_dma_lock(), release_dma_lock(), request_dma(), and free_dma(). Thus, there's a strict dependency on the config option and the driver should only be loaded if the kernel supports ISA-style DMA.
