This option adds NUMA support to the kernel.
- An operation mode can be selected by appending

- The default behaviour is identical to appending numa=plain to

- available memory and all CPUs in it.

- Numa emulation mode will split the available system memory into
- equal chunks which then are distributed over the configured number
- of nodes in a round-robin manner.
-
- The number of fake nodes is limited by the number of available memory
- chunks (i.e. memory size / fake size) and the number of supported
- nodes in the kernel.
-
- The CPUs are assigned to the nodes in a way that partially respects
- the original machine topology (if supported by the machine).
- Fair distribution of the CPUs is not guaranteed.
