459 | bool "Pseudo page fault support" | |
460 | help | |
461 | Select this option, if you want to use PFAULT pseudo page fault | |
462 | handling under VM. If running native or in LPAR, this option | |
463 | has no effect. If your VM does not support PFAULT, PAGEEX | |
464 | pseudo page fault handling will be used. | |
465 | Note that VM 4.2 supports PFAULT but has a bug in its | |
466 | implementation that causes some problems. | |
467 | Everybody who wants to run Linux under VM != VM4.2 should select | |
468 | this option. | |

484 | Select this option, if you want to enable the kernel interface | |
485 | to reduce the memory size of the system. This is accomplished | |
486 | by allocating pages of memory and put them "on hold". This only | |
487 | makes sense for a system running under VM where the unused pages | |
488 | will be reused by VM for other guest systems. The interface | |
489 | allows an external monitor to balance memory of many systems. | |
