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

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

64 help
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.

76 SPLPAR machines can log hypervisor preempt & dispatch events to a
77 kernel buffer. Saying Y here will enable logging these events,
78 which are accessible through a debugfs file.
