Subject: [PATCH] powerpc/qspinlock: Fix 32-bit build
Date: Thu, 8 Dec 2022 22:32:25 +1000 [thread overview]
Message-ID: <20221208123225.1566113-1-npiggin@gmail.com> (raw)
Some 32-bit configurations don't pull in the spin_begin/end/relax
definitions. Fix is to restore a lost include.
Reported-by: kernel test robot <lkp@intel.com>
Link: https://lore.kernel.org/oe-kbuild-all/202212050224.i7uh9fOh-lkp@intel.com
Fixes: 84990b169557 ("powerpc/qspinlock: add mcs queueing for contended waiters")
