Subject: [PATCH 4.4 07/31] arch/arc: add copy_user_page() to <asm/page.h> to fix build error on ARC
Date: Fri, 22 Jan 2021 15:08:21 +0100	[thread overview]
Message-ID: <20210122135732.165180021@linuxfoundation.org> (raw)
In-Reply-To: <20210122135731.873346566@linuxfoundation.org>

From: Randy Dunlap <rdunlap@infradead.org>

[ Upstream commit 8a48c0a3360bf2bf4f40c980d0ec216e770e58ee ]

fs/dax.c uses copy_user_page() but ARC does not provide that interface,
resulting in a build error.

Provide copy_user_page() in <asm/page.h>.

../fs/dax.c: In function 'copy_cow_page_dax':
../fs/dax.c:702:2: error: implicit declaration of function 'copy_user_page'; did you mean 'copy_to_user_page'? [-Werror=implicit-function-declaration]
