[dpdk-dev] [PATCH v6] kernel folder for Linux and BSD modules

[Hemant Agrawal <hemant.agrawal@nxp.com>]

This patch moves the kernel modules code from EAL to a common place.
 - Separate the kernel module code from user space code.

Signed-off-by: Hemant Agrawal <hemant.agrawal@nxp.com>
Tested-by: Bruce Richardson <bruce.richardson@intel.com>
---
v6: added meson build support
v5: rearrange kernel compliation as per Bruce's suggestion
v4: update the path in MAINTAINERS
v3: move contigmem from bsdapp
v2: rename kern to kernel, add freebsd modules as well
