Suppress gcc warning "warning: writing 16 bytes into a region of
size 0" for users of the POWER rte_memcpy() function. Existing
rte_memcpy() code takes different code paths based on the actual
size of the move so the warning is already addressed. See also

v2:
- update copyright year
- rebase for 21.11-rc0
David M,
Any chance of getting this approved in the 21.11 cycle? Patch was
originally submitted on 6/23, is only applicable to PPC architecture,
and has no functional impact because it only disables warnings.
Patchwork reports a performance test regression on x86 systems:
http://patches.dpdk.org/project/dpdk/patch/20210902221514.3215704-1-...@linux.vnet.ibm.com/
But I don't see how that is possible. Applying the patch on a local x86
system results in identical x86 binaries with and without the patch
applied. It would appear that the test-to-test performance variations
exceed the failure threshold on the CI setup.
