arm: Re-enable PI futex support for ARM kernels >= 3.14.3
ARM linux kernels before 3.14.3 may or may not support futex_atomic_cmpxchg_inatomic depending on the kernel configuration (e.g. CONFIG_CPU_USE_DOMAINS && CONFIG_SMP configuration was not supported) Starting with 3.14.3 the linux kernel unconditionally enables support for ARM, and this re-enables the relevant __ASSUME_* macros. Tested on ARM both with kernels >= 3.14.3 and older kernels. * sysdeps/unix/sysv/linux/arm/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x030E03] (__ASSUME_FUTEX_LOCK_PI): Do not undefine. [__LINUX_KERNEL_VERSION >= 0x030E03] (__ASSUME_REQUEUE_PI): Likewise. [__LINUX_KERNEL_VERSION >= 0x030E03] (__ASSUME_SET_ROBUST_LIST): Likewise.
