Subject: eal/x86: fix pedantic build
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=721ac9f9e063f55570c1c3a2f07cf5a7b5e15aab;p=dpdk.git

eal/x86: fix pedantic build

When enabling pedantic compilation with CONFIG_RTE_LIBRTE_MLX5_DEBUG,
the compiler complains about non standard 128-bit integer type:

include/rte_atomic_64.h:223:3: error:
ISO C does not support ‘__int128’ types [-Werror=pedantic]

It must be marked as an extension of the standard C language
to be accepted in pedantic compilation.

Fixes: 640c5f09ef2c ("eal/x86: add 128-bit atomic compare exchange")
