Hi Russell, After merging the arm tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/built-in.o: In function `__sp804_clocksource_and_sched_clock_init': (.init.text+0x1a0e7): undefined reference to `sched_clock_register' Presumably caused by commit 5261ef2ea836 ("ARM: 8366/1: move Dual-Timer SP804 driver to drivers/clocksource"). I have used the arm tree from next-20150528 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
