[dpdk-dev] [PATCH v2 0/3] fix build issues with librte_sched, test_red on non x86 platform

[Jerin Jacob]

This patch set enable librte_sched, app/test/test_sched and app/test/test_red
to build on non x86 platform

v1..v2  use memory barrier version rte_rdtsc() for multi arch support as
suggested by Thomas Monjalon

Jerin Jacob (3):
  sched: remove unused inclusion of tmmintrin.h
  app/test: test_sched: fix needless build dependency on
    CONFIG_RTE_ARCH_X86_64
  app/test: use memory barrier version of rte_rdtsc() eal api for multi
    arch support
