Hi Greg, After merging the tty tree, today's linux-next build (arm multi_v7_defconfig) failed like this: In file included from init/do_mounts.c:15:0: include/linux/tty.h:267:9: error: width of 'unused' exceeds its type unused:62; ^ include/linux/tty.h:271:9: error: width of 'unused_ctrl' exceeds its type unused_ctrl:55; ^ In file included from init/main.c:28:0: include/linux/tty.h:267:9: error: width of 'unused' exceeds its type unused:62; ^ include/linux/tty.h:271:9: error: width of 'unused_ctrl' exceeds its type unused_ctrl:55; ^ In file included from include/linux/serial_core.h:29:0, from include/linux/serial_s3c.h:236, from arch/arm/mach-exynos/exynos.c:15: include/linux/tty.h:267:9: error: width of 'unused' exceeds its type unused:62; ^ include/linux/tty.h:271:9: error: width of 'unused_ctrl' exceeds its type unused_ctrl:55; ^ In file included from include/linux/serial_core.h:29:0, from include/linux/platform_data/serial-omap.h:20, from arch/arm/mach-omap2/serial.c:30: include/linux/tty.h:267:9: error: width of 'unused' exceeds its type unused:62; ^ include/linux/tty.h:271:9: error: width of 'unused_ctrl' exceeds its type unused_ctrl:55; ^ Caused by commits c545b66c6922 ("tty: Serialize tcflow() with other tty flow control changes") and 99416322dd16 ("tty: Workaround Alpha non-atomic byte storage in tty_struct"). There are still 32 bit architectures out there! ;-) I have used the tty tree from next-20140924 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
