The rte_calloc function expects to get size_t (64 bits, unsigned) and instead gets a 32-bit variable, because the numeric constant size is a 32-bit. In case the shift is greater than 32 the variable will lose its value even though the function can get 64-bit argument. Change the size of the numeric constant 1 to 64-bit.
