[dpdk-dev] [PATCH v1 0/5] clean-up cpuflags

Following the work of Ferruh, I suggest this cleanup to remove as much
as possible of the code from the cpuflags headers.
The goal is to un-inline these functions (not performance sensitive)
and remove the CPU flags table from the ABI (just added recently).
The bonus is to stop mimic x86 in ARM and PPC implementations.

WARNING: it has not been tested nor compiled on Tilera, ARM and POWER8.
Please help, thank you.

Thomas Monjalon (5):
  eal: get CPU flag name
  eal: move CPU flag functions out of headers
  eal/arm: adapt CPU flags check to the arch
  eal/ppc: adapt CPU flags check to the arch
  eal: remove compiler optimization workaround
