[dpdk-dev] [PATCH v4 00/17] support multi-pthread per core

v4 changes:
  new patch fixing strnlen() invalid return in 32bit icc [03/17]
  update and add more comments on sched_yield() [16/17]

v3 changes:
  new patch adding sched_yield() in rte_ring to avoid long spin [16/17]

v2 changes:
  add '<number>-<number>' support for EAL option '--lcores' [02/17]

The patch series contain the enhancements of EAL and fixes for libraries
to run multi-pthreads(either EAL or non-EAL thread) per physical core.
Two major changes list as below:
- Extend the core affinity of each EAL thread to 1:n.
  Each lcore stands for a EAL thread rather than a logical core.
  The change adds new EAL option to allow static lcore to cpuset assginment.
  Then a lcore(EAL thread) affinity to a cpuset, original 1:1 mapping is the special case.
- Fix the libraries to allow running on any non-EAL thread.
  It fix the gaps running libraries in non-EAL thread(dynamic created by user).
  Each fix libraries take care the case of rte_lcore_id() >= RTE_MAX_LCORE.

Thanks a million for the comments from Konstantin, Bruce, Mirek and Stephen in RFC review.
