Subject: [PATCH 4.9 18/29] tools include: Drop ARRAY_SIZE() definition from linux/hashtable.h

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnaldo Carvalho de Melo <acme@...hat.com>

commit 68289cbd83eaa20faef7cc818121bc8e769065de upstream.

As tools/include/linux/kernel.h has it now, with the goodies present in
the kernel.h counterpart, i.e. checking that the parameter is an array
at build time.
