The GCC 4.9 -march option supports the intel code names for processors,
for example -march=silvermont, -march=broadwell.
The RTE_MACHINE config flag can be used to pass code name to
the compiler as -march flag.
Release notes is updated.
Linux and FreeBSD getting started guides are updated with recommended
gcc version as 4.9 and above.
Some of the gmake command examples in sample application guide and driver
guides are updated with gcc version as 4.9.

Following discussions on the mailing list [1] and since nobody stood up to
implement the necessary cleanups, here is the ivshmem integration removal.
There is not much to say about this patch, a lot of code is being removed.
The default configuration file for packet_ordering example is replaced with
the "native" x86 file.
The only tricky part is in eal_memory with the memseg index stuff.
More cleanups can be done after this but will come in subsequent patchsets.

The following tools may be installed system-wide.
It may be cleaner and more convenient to find them with the same
dpdk- prefix (especially for autocompletion).
Moreover, the script dpdk_nic_bind.py deserves a new name because it is
not restricted to NICs and can be used for e.g. crypto.
These files are renamed:
pmdinfogen -> dpdk-pmdinfogen
pmdinfo.py -> dpdk-pmdinfo.py
dpdk_pdump -> dpdk-pdump
dpdk_proc_info -> dpdk-procinfo
dpdk_nic_bind.py -> dpdk-devbind.py
setup.sh -> dpdk-setup.sh
The tools pmdinfogen, pmdinfo.py and dpdk_pdump are new in 16.07.
The scripts dpdk_nic_bind.py and setup.sh may have been used with
previous releases by end users. That's why a symbolic link still
provide the old name in the installed tools directory.

The commit 66819e6 has introduced a dependency on libarchive to be able
to use some tar resources in the unit tests.
It is now an optional dependency because some systems do not have it
installed.
If CONFIG_RTE_APP_TEST_RESOURCE_TAR is disabled, the PCI test will not
be run. When a "configure" script will be integrated, the libarchive
availability could be checked to automatically enable the option.

The driver i40e was using a specific PCI config before the release 16.04.
Since 16.04, it is always enabled in i40e (commit 56465cfaf).
The API has been deprecated in the commit 68f7759382.
The igb_uio implementation has been deprecated in commit b7cf8e155.

The uninstall procedure cannot be applied properly (without removing
