Subject: [PATCH 5.15 09/20] h8300: Fix build errors from do_exit() to make_task_dead() transition
Date: Tue, 24 Jan 2023 10:50:59 -0800	[thread overview]
Message-ID: <20230124185110.143857-10-ebiggers@kernel.org> (raw)
In-Reply-To: <20230124185110.143857-1-ebiggers@kernel.org>

From: Nathan Chancellor <nathan@kernel.org>

commit ab4ababdf77ccc56c7301c751dff49c79709c51c upstream.

When building ARCH=h8300 defconfig:

arch/h8300/kernel/traps.c: In function 'die':
arch/h8300/kernel/traps.c:109:2: error: implicit declaration of function
'make_dead_task' [-Werror=implicit-function-declaration]
  109 |  make_dead_task(SIGSEGV);
      |  ^~~~~~~~~~~~~~

arch/h8300/mm/fault.c: In function 'do_page_fault':
arch/h8300/mm/fault.c:54:2: error: implicit declaration of function
'make_dead_task' [-Werror=implicit-function-declaration]
   54 |  make_dead_task(SIGKILL);
      |  ^~~~~~~~~~~~~~

The function's name is make_task_dead(), change it so there is no more
build error.

Additionally, include linux/sched/task.h in arch/h8300/kernel/traps.c
to avoid the same error because do_exit()'s declaration is in kernel.h
but make_task_dead()'s is in task.h, which is not included in traps.c.

Fixes: 0e25498f8cd4 ("exit: Add and use make_task_dead.")
