Subject: RISC-V: cpu_ops_spinwait.c should include head.h
From: Ben Dooks <ben.dooks@xxxxxxxxxx>
commit e4aa991c05aedc3ead92d1352af86db74090dc3c upstream.
Running sparse shows cpu_ops_spinwait.c is missing two definitions
found in head.h, so include it to stop the following warnings:
arch/riscv/kernel/cpu_ops_spinwait.c:15:6: warning: symbol '__cpu_spinwait_stack_pointer' was not declared. Should it be static?
arch/riscv/kernel/cpu_ops_spinwait.c:16:6: warning: symbol '__cpu_spinwait_task_pointer' was not declared. Should it be static?
