+Subject: tile: remove compat_sys_lookup_dcookie declaration to fix compile error
+
+From: Heiko Carstens <heiko.carstens@de.ibm.com>
+
+commit 5a5e75f4714a592f31e57f248b8f5c866f278b8d upstream.
+
+With commit d8d14bd09cdd ("fs/compat: fix lookup_dcookie() parameter
+handling") I changed the type of the len parameter of the
+lookup_dcookie() syscall.
+
+However I missed that there was still a stale declaration in
+arch/tile/.. which now causes a compile error on tile:
+
+ In file included from fs/dcookies.c:28:0:
+ include/linux/compat.h:425:17: error: conflicting types for 'compat_sys_lookup_dcookie'
+ fs/dcookies.c:207:1: error: conflicting types for 'compat_sys_lookup_dcookie'
+
+Simply remove the declaration in the tile architecture, which is only a
+leftover from before the different compat lookup_dcookie() versions have
+been merged. The correct declaration is now in include/linux/compat.h
+
+The build error was reported by Fenguang's build bot.
