With this option a system running in an LPAR can be given more memory than physically available and will allow firmware to balance memory across many LPARs. config CMM tristate "Collaborative memory management" depends on PPC_SMLPAR && !CRASH_DUMP default y 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.
