[dpdk-stable] patch 'acl: fix build with some arm64 compiler' has been queued to LTS release 18.11.3

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to LTS release 18.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/26/19. 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/a8c67a4d4aeebea552a9dcf18b6b3d2d4610e8d9

Thanks.

Kevin Traynor

Subject: [PATCH] acl: fix build with some arm64 compiler

[ upstream commit 557c5cbde374172c7140bc6a7cef2cc81e5a29dc ]

Some compilers reporting the following error, though the existing
code doesn't have any uninitialized variable case.
Just to make compiler happy, initialize the int32x4_t variable
one shot using vdupq_n_s32.

lib/librte_acl/acl_run_neon.h: In function 'search_neon_4'
lib/librte_acl/acl_run_neon.h:230:12: error:
  'input' may be used uninitialized in this function
  int32x4_t input;

Fixes: 34fa6c27c156 ("acl: add NEON optimization for ARMv8")
