Subject: [PATCH 1/2] move swiotlb.h header file to asm-generic (revised)
Date: Sun, 12 Feb 2006 19:40:52 -0600 [thread overview]
Message-ID: <20060213014051.GA7798@us.ibm.com> (raw)
This patch is a cut down version of the one Muli submitted on January
24th (http://lkml.org/lkml/2006/1/24/262). It removes the miscellaneous
changes from "int" to "enum dma_data_direction", and only contains the
move to asm-generic.
Thanks,
Jon
