[dpdk-dev] [PATCH v4 00/15] Support ARMv7 architecture

[Jan Viktorin <viktorin@rehivetech.com>]

Hello DPDK community,

This is the 4th series of the ARMv7 patchset. I've cleaned up
most checkpatch errors:

* Whitespaces were fixed.

* The asm volatile syntax (checkpatch didn't like the named "%xyz"
  parameters when listed in the InputOperands list as "[xyz]").

* There are still few complaints (documented in each patch) but
  I consider them as unimportant (volatile, couple of line overlaps,
  new typedef). If it still can be done better, please report me
  your ideas.

Other changes:

* The "introduction patch" was moved to be almost the last patch as
  suggested by D. Marchand.
  
* I've added a note into the release_2_2.rst.

* The RTE_BITMAP_OPTIMIZATIONS was removed.

* The ARMv7 defconfig was renamed as suggested by B. Richardson.

* I've removed the LPM and ACL fixes from the patchset for now.
  The libraries table and pipeline are disabled as well.

* The igb_uio driver is disabled.

* The -Wno-error was restricted to cast-align only.

To be answered (from rte_atomic.h patch):

* use __atomic_* or __sync_*? (may affect the required GCC version)

Regards
Jan
