I believe Andrew has picked it up for his mm series which is haphazardly merged into -next. ----------- On Thu, 2013-11-07 at 10:54 +0800, kbuild test robot wrote: > tree: git://git.cmpxchg.org/linux-mmotm.git master > head: 7610384ab26340452f06d673c46624927c3901b6 > commit: 7231446cc53d71e126acf3d0230239a6b3ad52bf [169/450] printk/cache: Mark printk_once test variable __read_mostly > config: make ARCH=ia64 alldefconfig > > All error/warnings: Hello Fengguang. > In file included from arch/ia64/kernel/patch.c:12:0: > arch/ia64/include/asm/processor.h: In function 'ia64_get_irr': > >> arch/ia64/include/asm/processor.h:565:2: error: implicit declaration of function 'test_bit' [-Werror=implicit-function-declaration] I'm a bit confused how the change I made could cause this error. Is this an existing warning that's now an error because bitops.h isn't explicitly #included in processor.h?
