Hi Samuel, Today's linux-next build (x86_64 allmodconfig) failed like this: drivers/mtd/nand/tmio_nand.c: In function 'tmio_nand_write_buf': drivers/mtd/nand/tmio_nand.c:251: error: implicit declaration of function 'writesw' drivers/mtd/nand/tmio_nand.c: In function 'tmio_nand_read_buf': drivers/mtd/nand/tmio_nand.c:258: error: implicit declaration of function 'readsw' Most architectures don't implement readsw/writesw. I reverted commit 4d6da2de1b09228989efb67a1f9e6d2ced075540 ("mfd: driver for the TMIO NAND controller") until it has tighter controls in its Kconfig patch. i.e. I have no idea what arches this should be built on. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
