This patchset fixes performance/cache resource issues with 128-byte cache line targets
found in mbuf and bitmap DPDK libraries

Currently, we have two DPDK targets(ThunderX and ppc_64) which are based on
128-bytes cache line size target.
When introducing IBM Power8, we failed to clean the cache line size definition.
I promised to not forget this issue in this thread with Neil:
	http://dpdk.org/ml/archives/dev/2014-December/009439.html

It is defined in
	config/defconfig_*
	mk/machine/*/rte.vars.mk
	mk/arch/*/rte.vars.mk
	rte_memory.h
	rte_kni_common.h

It should be defined only in the config files.
When we will introduce a configure script, we should be able to detect it.

Please Jerin, as ThunderX maintainer, may you help to fix this old mess?
Yes Thomas, I will takeup this issue when we will have configure script.
apart from that, content of the this patch will be still valid
as the fix going to be generating cache line define from the config file.

Jerin
Thanks
