"Zone Order" orders the zonelists by zone type, then by node within each
zone. Specify "[Zz]one" for zone order.
Specify "[Dd]efault" to request automatic configuration. Autoconfiguration
will select "node" order in following case.
(1) if the DMA zone does not exist or
(2) if the DMA zone comprises greater than 50% of the available memory or
(3) if any node's DMA zone comprises greater than 70% of its local memory and
the amount of local memory is big enough.
Specify "[Dd]efault" to request automatic configuration.
Otherwise, "zone" order will be selected. Default order is recommended unless
this is causing problems for your system/application.
On 32-bit, the Normal zone needs to be preserved for allocations accessible
by the kernel, so "zone" order will be selected.
On 64-bit, devices that require DMA32/DMA are relatively rare, so "node"
order will be selected.
Default order is recommended unless this is causing problems for your
system/application.
