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

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi all,

After merging the mm tree, today's linux-next build (sparc defconfig)
failed like this:

lib/objpool.c: In function '__objpool_try_get_slot':
lib/objpool.c:378:17: error: implicit declaration of function 'prefetch' [-Werror=implicit-function-declaration]
  378 |                 prefetch(&ents[id]);
      |                 ^~~~~~~~
cc1: some warnings being treated as errors

Caused by commit

  080ae5bb93cd ("kprobes,lib: kretprobe scalability improvement")

I have reverted that commit for today (and its followup fix patch).
