Subject: linux-next: build failure after merge of the tip tree

Hi all,

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

ERROR: modpost: too long symbol ".__tracepoint_iter_pnfs_mds_fallback_pg_get_mirror_count" [fs/nfs/flexfilelayout/nfs_layout_flexfiles.ko]

Caused by commit

  d25e37d89dd2 ("tracepoint: Optimize using static_call()")

Exported symbols need to be <= (64 - sizeof(Elf_Addr)) long.  This is
presumably 56 on 64 bit arches and the above symbol (including the '.')
is 56 characters long.

I have reverted that commit for today.
