[dpdk-stable] patch 'eal: fix casts in random functions' has been queued to LTS release 17.11.5

[Yongseok Koh <yskoh@mellanox.com>]

Hi,

FYI, your patch has been queued to LTS release 17.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 01/04/19. 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. 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.

Yongseok

Subject: [PATCH] eal: fix casts in random functions

[ upstream commit d3db77d7d88e1f9227c2847f3355fc3e4bd256e8 ]

GCC 8.1 warns:

In function 'rte_srand':
rte_random.h:34:10:
warning: conversion to 'long int' from 'long unsigned int'
may change the sign of the result [-Wsign-conversion]
  srand48((long unsigned int)seedval);

rte_random.h:51:8:
warning: conversion to 'uint64_t' {aka 'long unsigned int'}
from 'long int' may change the sign of the result
[-Wsign-conversion]
  val = lrand48();
        ^~~~~~~

rte_random.h:53:6:
warning: conversion to 'long unsigned int' from 'long int'
may change the sign of the result [-Wsign-conversion]
  val += lrand48();

Fixes: af75078fece3 ("first public release")
