[dpdk-dev] [PATCH v3 0/9] Dynamic memzone

Current implemetation allows reserving/creating memzones but not the opposite
(unreserve/free). This affects mempools and other memzone based objects.
>From my point of view, implementing free functionality for memzones would look
like malloc over memsegs.
Thus, this approach moves malloc inside eal (which in turn removes a circular
dependency), where malloc heaps are composed of memsegs.
We keep both malloc and memzone APIs as they are, but memzones allocate its
memory by calling malloc_heap_alloc.
Some extra functionality is required in malloc to allow for boundary constrained
memory requests.
In summary, currently malloc is based on memzones, and with this approach
memzones are based on malloc.
v3:
- Create dummy librte_malloc
- Add deprecation notice
- Rework some of the code
- Doc update
- checkpatch
v2:
- New rte_memzone_free
- Support memzone len = 0
- Add all available memsegs to malloc heap at init
- Update memzone/malloc unit tests
Sergio Gonzalez Monroy (9):
eal: move librte_malloc to eal/common
eal: memzone allocated by malloc
app/test: update malloc/memzone unit tests
config: remove CONFIG_RTE_MALLOC_MEMZONE_SIZE
eal: remove free_memseg and references to it
eal: new rte_memzone_free
app/test: update unit test with rte_memzone_free
doc: announce ABI change of librte_malloc
doc: update malloc documentation
