Hi all, After merging the tip tree, today's linux-next build (arm multi_v7_defconfig) failed like this: drivers/clocksource/versatile.c: In function 'versatile_sched_clock_init': drivers/clocksource/versatile.c:37:2: error: implicit declaration of function 'setup_sched_clock' [-Werror=implicit-function-declaration] Caused by commit c04ae71c9c26 ("sched_clock: Remove deprecated setup_sched_clock() API") from the tip tree. The usage was only added to Linus' tree today by commit 220e2a8d22cd ("clocksource: Sched clock source for Versatile Express") (but this commit has been in linux-next since May 22 at least). I have reverted the tip tree commit for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
