[dpdk-stable] patch 'eal: fix parentheses in alignment macros' has been queued to LTS release 18.11.10

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/25/20. 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/53d8ebacc1392439d183de6dd65ca8bee7ce16c5

Thanks.

Kevin.

Subject: [PATCH] eal: fix parentheses in alignment macros

[ upstream commit 3596a037ab44a1ad588fb388d5d4ee8f3d2a1ca7 ]

Found an issue while using RTE_ALIGN_MUL_NEAR with an
expression, like as passed in estimate_tsc_freq().
RTE_ALIGN_MUL_FLOOR resulted in unexpected value as
parathesis are required to evaluate an expression.

Fixes: 5120203d753f ("eal: add macros to align value to multiple")
