From: John W. Linville Date: Mon, 7 Nov 2005 08:57:54 +0000 (-0800) Subject: [PATCH] ia64: re-implement dma_get_cache_alignment to avoid EXPORT_SYMBOL X-Git-Tag: v2.6.15-rc1~711 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e1531b4218a7ccfc1b2234b87105201e5ebe1bbf;p=linux-2.6 [PATCH] ia64: re-implement dma_get_cache_alignment to avoid EXPORT_SYMBOL The current ia64 implementation of dma_get_cache_alignment does not work for modules because it relies on a symbol which is not exported. Direct access to a global is a little ugly anyway, so this patch re-implements dma_get_cache_alignment in a manner similar to what is currently used for x86_64. Signed-off-by: John W.
