linux-next: build failure after merge of the akpm tree

[Stephen Rothwell]

Hi all,

After merging the akpm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

mm/madvise.c: In function 'madv_import_iovec':
mm/madvise.c:1233:6: error: implicit declaration of function 'in_compat_syscall' [-Werror=implicit-function-declaration]
 1233 |  if (in_compat_syscall())
      |      ^~~~~~~~~~~~~~~~~

Caused by commit

  6d0ecd769ce2 ("mm/madvise: introduce process_madvise() syscall: an external memory hinting API")

I added the following fix up patch.
