Hi Greg, After merging the tty tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: drivers/tty/n_tty.c: In function 'n_tty_close': drivers/tty/n_tty.c:1757:2: error: implicit declaration of function 'vfree' [-Werror=implicit-function-declaration] vfree(ldata); ^ drivers/tty/n_tty.c: In function 'n_tty_open': drivers/tty/n_tty.c:1776:2: error: implicit declaration of function 'vmalloc' [-Werror=implicit-function-declaration] ldata = vmalloc(sizeof(*ldata)); ^ drivers/tty/n_tty.c:1776:8: warning: assignment makes pointer from integer without a cast [enabled by default] ldata = vmalloc(sizeof(*ldata)); ^ Caused by commit 20bafb3d23d1 ("n_tty: Move buffers into n_tty_data"). Forgot to include linux/vmalloc.h? I have used the tty tree from next-20130723 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
