| 65 | Select this option, if you want to enable the kernel interface |
| 66 | to reduce the memory size of the system. This is accomplished |
| 67 | by allocating pages of memory and put them "on hold". This only |
| 68 | makes sense for a system running in an LPAR where the unused pages |
| 69 | will be reused for other LPARs. The interface allows firmware to |
| 70 | balance memory across many LPARs. |
