sdbio() tests if it can pass the buffer pointer directly to the driver when it is already in kernel memory. we also need to check if the buffer is properly aligned but alignment requirement is handled in system specific sdmalloc() and was not known to devsd. to solve this, we *always* page align sd buffers and get rid of the system specific sdmalloc() macro (was only used in bcm kernel). |
