Patch from Nicolas Pitre Strictly speaking, the NPTL kernel helpers are required for pre ARMv6 only. They are available on ARMv6+ as well for obvious compatibility reasons. However there are cases where extra memory barriers are needed when using an SMP ARMv6 machine but not on pre-ARMv6. This patch adds a memory barrier kernel helper that glibc can use as needed for pre-ARMv6 binaries to be forward compatible with an SMP kernel on ARMv6, as well as the necessary dmb instructions to the cmpxchg helper.
