[dpdk-dev] [PATCH V2 1/1] eal: fix build with conflicting libc variable memory_order

> 
> The cited commit introduced functions with 'int memory_order' argument.
> The C11 standard section 7.17.1.4 defines 'memory_order' as the

> constraints".
> 
> A compilation error occurs:
> error: declaration of 'memory_order' shadows a global declaration
>     [-Werror=shadow]
>      rte_atomic_thread_fence(int memory_order)
> 
> This issue was hit when trying to compile OVS with gcc 4.8.5. This compiler
> version does not provide stdatomic.h, so enum memory_order is redefined
> in OVS code.
> In another case, if the compiler does provide stdatomic.h header, passing -
> Wsystem-headers in the CFLAGS will also cause that failure.
> 
> Fix it by changing the argument name 'memory_order' to 'memorder'.
