Fix the clang compiler error on x86 when the above FORCE_INTRINSICS\n   is enabled.\n\nV1:\n1. Remove the 1us delay outside of the locked region to really benchmark\n   the spinlock acquire/release performance, not the delay API.\n2. Use the precise version of getting timestamps for more precise\n   benchmarking results.\n3. Amortize the overhead of getting the timestamp by 10000 loops.\n4. Move the arm specific implementation to arm folder to remove the\n   hardcoded implementation.\n5. Use atomic primitives, which translate to one-way barriers, instead of\n   two-way sync primitives, to optimize for performance.\n\nGavin Hu (5):\n  test/spinlock: remove 1us delay for correct benchmarking\n  test/spinlock: get timestamp more precisely\n  test/spinlock: amortize the cost of getting time\n  spinlock: reimplement with atomic one-way barrier builtins\n  eal: fix clang compilation error on x86\n\n lib/librte_eal/common/include/generic/rte_atomic.h |  6 ++--\n .../common/include/generic/rte_spinlock.h          | 18 ++++++++----\n test/test/test_spinlock.c                          | 32 +++++++++++-----------\n 3 files changed, 32 insertions(+), 24 deletions(-)",
