| 21 | Enabling this option will make the kernel run more efficiently | |
| 22 | on logically-partitioned pSeries systems which use shared | |
| 23 | processors, that is, which share physical processors between | |
| 24 | two or more partitions. | |

| 58 | Select this option to enable shared memory partition support. | |
| 59 | With this option a system running in an LPAR can be given more | |
| 60 | memory than physically available and will allow firmware to | |
| 61 | balance memory across many LPARs. | |

| 67 | help | |
| 68 | Select this option, if you want to enable the kernel interface | |
| 69 | to reduce the memory size of the system. This is accomplished | |
| 70 | by allocating pages of memory and put them "on hold". This only | |
| 71 | makes sense for a system running in an LPAR where the unused pages | |
| 72 | will be reused for other LPARs. The interface allows firmware to | |
| 73 | balance memory across many LPARs. | |

| 79 | SPLPAR machines can log hypervisor preempt & dispatch events to a | |

| 83 | Say N if you are unsure. |
