The xtensa architecture already has __cmpxchg_local defined but not used.
The purpose of __cmpxchg_local() is solely for arch_cmpxchg_local(), just
as the definition of arch_cmpxchg_local() for other architectures like x86,
arm and powerpc.

hexagonc hasn't arch_cmpxhg_local implemented, which causes
building failures for any references of try_cmpxchg_local,
reported by the kernel test robot.
This patch implements arch_cmpxchg[64]_local with the native
cmpxchg variant if the corresponding data size is supported,
otherwise
openrisc hasn't arch_cmpxhg_local implemented, which causes
building failures for any references of try_cmpxchg_local,
reported by the kernel test robot.

arc doesn't have arch_cmpxhg_local implemented, which causes

arch_cmpxchg() should check data size rather than pointer size in case
CONFIG_ARC_HAS_LLSC is defined. So rename __cmpxchg to __cmpxchg_32 to
emphasize it's explicit support of 32bit data size with BUILD_BUG_ON()
added to avoid any possible misuses with unsupported data types.
In case
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
