Arnd Bergmann 76da46c25d syscalls: fix sys_fanotify_mark prototype ...

[ Upstream commit 63e2f40c9e ]

My earlier fix missed an incorrect function prototype that shows up on
native 32-bit builds:

In file included from fs/notify/fanotify/fanotify_user.c:14:
include/linux/syscalls.h:248:25: error: conflicting types for 'sys_fanotify_mark'; have 'long int(int,  unsigned int,  u32,  u32,  int,  const char *)' {aka 'long int(int,  unsigned int,  unsigned int,  unsigned int,  int,  const char *)'}
 1924 | SYSCALL32_DEFINE6(fanotify_mark,
      | ^~~~~~~~~~~~~~~~~
include/linux/syscalls.h:862:17: note: previous declaration of 'sys_fanotify_mark' with type 'long int(int,  unsigned int,  u64,  int, const char *)' {aka 'long int(int,  unsigned int,  long long unsigned int,  int,  const char *)'}

On x86 and powerpc, the prototype is also wrong but hidden in an #ifdef,
so it never caused problems.

Add another alternative declaration that matches the conditional function
definition.
