[dpdk-dev] [PATCH 00/24] 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).

Aaron Conole (24):
  eal: CPU init will no longer panic
  eal: return error instead of panic for cpu init
  eal: No panic on hugepages info init
  eal: do not panic on failed hugepage query
  eal: failure to parse args returns error
  eal-common: introduce a way to query cpu support
  eal: Signal error when CPU isn't supported
  eal: do not panic on memzone initialization fails
  eal: set errno when exiting for already called
  eal: Do not panic on log failures
  eal: Do not panic on pci-probe
  eal: do not panic on vfio failure
  eal: do not panic on memory init
  eal: do not panic on tailq init
  eal: do not panic on alarm init
  eal: convert timer_init not to call panic
  eal: change the private pipe call to reflect errno
  eal: Do not panic on interrupt thread init
  eal: do not error if plugins fail to init
  eal_pci: Continue probing even on failures
  eal: do not panic on failed PCI probe
  eal_common_dev: continue initializing vdevs
  eal: do not panic (or abort) if vdev init fails
  eal: do not panic when bus probe fails
