Date: Tue, 14 Oct 2008 19:08:23 -0700 From: Jeremy Fitzhardinge <jeremy@...p.org> To: Ingo Molnar <mingo@...e.hu> CC: Andrew Morton <akpm@...ux-foundation.org>, Joerg Roedel <joerg.roedel@....com>, Jan Beulich <jbeulich@...ell.com>, Tony Luck <tony.luck@...el.com>, FUJITA Tomonori <fujita.tomonori@....ntt.co.jp>, Linux Kernel Mailing List <linux-kernel@...r.kernel.org> Subject: [PATCH 1/2] swiotlb: create appropriate common header for swiotlb swiotlb.c was moved into lib/ as a generic service, but its prototypes are still in asm-x86. Move the common parts to linux/swiotlb.h, and update the users accordingly.
