| help |
| Select this option, if you want to enable the kernel interface |
| to reduce the memory size of the system. This is accomplished |
| by allocating pages of memory and put them "on hold". This only |
| makes sense for a system running in an LPAR where the unused pages |
| will be reused for other LPARs. The interface allows firmware to |
| balance memory across many LPARs. |

| SPLPAR machines can log hypervisor preempt & dispatch events to a |
| kernel buffer. Saying Y here will enable logging these events, |
| which are accessible through a debugfs file. |
| |
| Say N if you are unsure. |
