Subject: mm/kmemleak: increase the max mem pool to 1M
There are some machines with slow disk and fast CPUs. When they are under
memory pressure, it could take a long time to swap before the OOM kicks in
to free up some memory. As the results, it needs a large mem pool for
kmemleak or suffering from higher chance of a kmemleak metadata allocation
failure. 524288 proves to be the good number for all architectures here.
Increase the upper bound to 1M to leave some room for the future.
