Archtectures arc, openrisc and hexagon haven't arch_cmpxchg_local() defined, so the usecase of try_cmpxchg_local() in lib/objpool.c can not pass kernel building by the kernel test robot.
Patch 1 improves the data size checking logic for arc; Patches 2/3/4 implement arch_cmpxchg[64]_local for arc/openrisc/hexagon. Patch 5 defines arch_cmpxchg_local as existing __cmpxchg_local rather the generic variant.
wuqiang.matt (5): arch,locking/atomic: arc: arch_cmpxchg should check data size arch,locking/atomic: arc: add arch_cmpxchg[64]_local arch,locking/atomic: openrisc: add arch_cmpxchg[64]_local arch,locking/atomic: hexagon: add arch_cmpxchg[64]_local arch,locking/atomic: xtensa: define arch_cmpxchg_local as __cmpxchg_local
