Hi Anatoly,
I am trying to verify this patchset and have encountered few issues.
Few -Werror=maybe-uninitialized errors in eal_memalloc.c/eal_memory.c/
eal_common_memzone.c files.

@Hemanth
Also, this patchset breaks dpaa/dpaa2 bus drivers (they rely on
`rte_eal_get_physmem_layout` that is depricated
http://dpdk.org/dev/patchwork/patch/34002/)
So, generic arm64 linuxapp build is broken.

Pavan.
