sh: fix function signature of cpu_coregroup_mask to match pointer typesh-fixes-4.6-rc1
The signedness mismatch of the argument type produces an error compiling kernel/sched/core.c with -Werror=incompatible-pointer-types, which is now used by default. Fixes: ea8daa7b9784 "kbuild: Add option to turn incompatible pointer check into error" Signed-off-by: Rich Felker <>
