Subject: [PATCH] numademo: fix error on 32bit system

Error Info on 32bit:
root@intel-x86:~# numademo -t -e 1M
Configured Nodes does not match available memory nodes

That's because sizeof(long)=4Word, but sizeof(long long)=8Word
on 32bit. So (long long) assigning to (long) maybe cause overflow.

long numa_node_size(int node, long *freep)
{
    ...
    long sz = numa_node_size64_int(node, &f2);
    ~^^~
    return sz;
    ...
}
long long numa_node_size64(int node, long long *freep)
~^^   ^^~
{
    ...
}

Unify the return type of above functions.

Upstream-Status: Accepted [next version is after 2.0.13 or 2.0.14]
