[dpdk-dev] [PATCH v3 00/14] Patches for DPDK to support Power architecture

The set of patches add IBM Power architecture to the DPDK. It adds the required support to the
EAL library. This set of patches doesn't support full DPDK function on Power processors. So a
separate common configuration file is used for Power to turn off some un-migrated functions. To
compile on PPC64 architecture, GCC version >= 4.8 must be used. This v3 patch updates eal_memory.c
to fix the memory zone allocation and also solves the compiling problems of test-pmd.

Chao Zhu (14):
  Add compiling definations for IBM Power architecture
  Add atomic operations for IBM Power architecture
  Add byte order operations for IBM Power architecture
  Add CPU cycle operations for IBM Power architecture
  Add prefetch operation for IBM Power architecture
  Add spinlock operation for IBM Power architecture
  Add vector memcpy for IBM Power architecture
  Add CPU flag checking for IBM Power architecture
  Remove iopl operation for IBM Power architecture
  Add cache size define for IBM Power Architecture
  Add huge page size define for IBM Power architecture
  Add eal memory support for IBM Power Architecture
  test_memzone:fix finding the second smallest segment
  Fix the compiling of test-pmd on IBM Power Architecture
