[dpdk-dev] [PATCH 1/3] mem: fix 32-bit memory upper limit for non-legacy mode

[Anatoly Burakov]

32-bit mode has an upper limit on amount of VA space it can preallocate,
but the original implementation used the wrong constant, resulting in
failure to initialize due to integer overflow. Fix it by using the
correct constant.

Fixes: 66cc45e293ed ("mem: replace memseg with memseg lists")
