[dpdk-stable] patch 'mk: disable OcteonTx for buggy compilers only on arm64' has been queued to stable release 18.08.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 18.08.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/23/18. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Kevin Traynor

Subject: [PATCH] mk: disable OcteonTx for buggy compilers only on arm64

[ upstream commit f3af3e44a444cdfe3fa7b3e2c042be351401eb23 ]

Disable octeontx for gcc 4.8.5 as the compiler is emitting "internal
compiler error" for aarch64. The GCC "internal compiler error" was
observed only for arm64 architecture so disable the PMD only
for arm64.

Fixes: 4f760550a093 ("mk: disable OcteonTx for buggy compilers")
