Hi Andrew, After merging the akpm tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/base/regmap/regcache-lzo.c: In function 'regcache_lzo_sync': drivers/base/regmap/regcache-lzo.c:344:2: error: implicit declaration of function 'for_each_set_bit_cont' [-Werror=implicit-function-declaration] drivers/base/regmap/regcache-lzo.c:345:41: error: expected ';' before '{' token drivers/base/regmap/regcache-lzo.c:340:6: warning: unused variable 'ret' [-Wunused-variable] drivers/base/regmap/regcache-lzo.c:338:15: warning: unused variable 'val' [-Wunused-variable] drivers/base/regmap/regcache-lzo.c:368:1: warning: no return statement in function returning non-void [-Wreturn-type] Caused by commits ac8d91c80190 ("regmap: Supply ranges to the sync operations" and a0941e562e80 ("regmap: Fix x86_64 breakage") from the regmap tree interacting with commits "bitops: rename for_each_set_bit_cont() in favor of analogous list.h function" and "bitops: remove for_each_set_bit_cont()" from the akpm tree.
