sparse identifies these missing prototypes when building arch/riscv:
arch/riscv/kernel/cpu.c:149:29: warning: symbol 'cpuinfo_op' was not declared.
Should it be static?
arch/riscv/kernel/irq.c:27:29: warning: symbol 'do_IRQ' was not declared.
Should it be static?
arch/riscv/kernel/irq.c:57:13: warning: symbol 'init_IRQ' was not declared.
Should it be static?
arch/riscv/kernel/syscall_table.c:15:6: warning: symbol 'sys_call_table' was
not declared. Should it be static?
arch/riscv/kernel/time.c:15:13: warning: symbol 'time_init' was not declared.
Should it be static?
arch/riscv/kernel/smpboot.c:135:24: warning: symbol 'smp_callin' was not
declared. Should it be static?
arch/riscv/kernel/smp.c:72:5: warning: symbol 'setup_profiling_timer' was not
declared. Should it be static?
arch/riscv/mm/init.c:151:7: warning: symbol 'trampoline_pg_dir' was not
declared. Should it be static?
arch/riscv/mm/init.c:157:7: warning: symbol 'early_pg_dir' was not declared.
Should it be static?
arch/riscv/kernel/process.c:32:6: warning: symbol 'show_regs' was not declared.
Should it be static?
arch/riscv/kernel/ptrace.c:151:6: warning: symbol 'do_syscall_trace_enter' was
not declared. Should it be static?
arch/riscv/kernel/ptrace.c:165:6: warning: symbol 'do_syscall_trace_exit' was
not declared. Should it be static?
Fix by adding the missing prototypes to the appropriate header files.
This change should have no functional impact.
