[PATCH v16 0/8] Lcore variables

[Mattias Rönnblom]

This patch set introduces a new API <rte_lcore_var.h> for static
per-lcore id memory allocation.

Lcore variables are designed to replace static lcore id-indexed arrays
and thread-local storage.

Refer to the programmer's guide for a rationale and comparison with
alternatives.

Mattias Rönnblom (8):
  eal: add static per-lcore memory allocation facility
  eal: add lcore variable functional tests
  eal: add lcore variable performance test
  eal: add lcore variables' programmer's guide
  random: keep PRNG state in lcore variable
  power: keep per-lcore state in lcore variable
  service: keep per-lcore state in lcore variable
  eal: keep per-lcore power intrinsics state in lcore variable
