[dpdk-dev] [PATCH v2 00/25] linux/eal: Remove most causes of panic on init

In many cases, it's enough to simply let the application know that the
call to initialize DPDK has failed. A complete halt can then be
decided by the application based on error returned (and the app could
even attempt a possible re-attempt after some corrective action by the
user or application).
Changes ->v2:
- Audited all "RTE_LOG (" calls that were introduced, and converted
to "RTE_LOG("
- Added some fprintf(stderr, "") lines to indicate errors before logging
is initialized
- Removed assignments to errno.
- Changed patch 14/25 to reflect EFAULT, and document in 25/25
I kept the rte_errno reflection, since this is control-path code and the
init function returns a sentinel value of -1.

eal: return error instead of panic for cpu init
eal: No panic on hugepages info init
eal: do not panic on failed hugepage query
