[PATCH v1 0/7] support reinit flow

[okaya at kernel.org]

From: Sinan Kaya <okaya at kernel.org>

We want to be able to call rte_eal_init() and rte_eal_cleanup()
APIs back to back for maintanance reasons.

Here is a summary of the code we have seen so far:

1. some code support getting called multiple times by keeping
a static variable.
2. some code initializes once but never clean up after them and
don't have a cleanup API.
3. some code assumes that they only get called once during the
lifecycle of the process.

Most changes in this patch center around following the #1 design
principle.

Graham Whyte (1):
  eal: fixes for re-initialization issues

Sinan Kaya (6):
  tailq: skip init if already initialized
  eal_memzone: bail out on initialized
  memseg: init once
  eal_memory: skip initialization
  eal_interrupts: don't reinitialize threads
  eal: initialize worker threads once
