Hi Andrew, After merging the akpm-current tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/input/joystick/walkera0701.c:153:4: error: implicit declaration of function 'abs64' [-Werror=implicit-function-declaration] if (abs64(pulse_time - SYNC_PULSE) < RESERVE) /* new frame sync */ ^ Caused by commit ea91f9c72512 ("Remove abs64()") interacting with commit 46b018fa9500 ("Input: walkera0701 - fix abs() calculations on 64 bit values") from the input-current tree. I just reverted 46b018fa9500 as ti will no longer be needed. -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
