[dpdk-stable] patch 'drivers/crypto: disable gcc 10 fno-common errors' has been queued to LTS release 18.11.9

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to LTS release 18.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/19/20. 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. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/500e41cae5ce1e7c456101aa5848c769450e6d09

Thanks.

Kevin.

Subject: [PATCH] drivers/crypto: disable gcc 10 fno-common errors

[ upstream commit 50b03f3b8eaf725c9e9b35f614c4a33f9623e29a ]

gcc 10 defaults to -fno-common and as a result when linking
with crypto drivers:

drivers/librte_pmd_dpaa_sec.a(crypto_dpaa_sec_dpaa_sec.c.o):
(.bss+0x4): multiple definition of `rta_sec_era';
drivers/librte_pmd_caam_jr.a(crypto_caam_jr_caam_jr.c.o):
(.bss+0x0): first defined here

drivers/librte_pmd_dpaa2_sec.a(crypto_dpaa2_sec_dpaa2_sec_dpseci.c.o):
(.data+0x0): multiple definition of `rta_sec_era';
drivers/librte_pmd_caam_jr.a(crypto_caam_jr_caam_jr.c.o):
(.bss+0x0): first defined here

This is a blunt fix for the issue by enabling fcommon for
dpaa_sec/dpaa2_sec/caam_jr.
