[PATCH] ARM: Ensure DMA-bounced buffers are properly written to RAM When DMA bounce buffers were unmapped and the data was memcpy'd to the original buffer, we were not ensuring that the data was written to RAM. This means that there was the potential for page cache pages to have different cache states depending whether they've been bounced or not. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
