+config PS3_HTAB_SIZE
+       depends on PPC_PS3
+       int "PS3 Platform pagetable size"
+       range 18 20
+       default 20
+       help
+         This option is only for experts who may have the desire to fine
+         tune the pagetable size on their system.  The value here is
+         expressed as the log2 of the page table size.  Valid values are
+         18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively.
+
+         If unsure, choose the default (20) with the confidence that your
+         system will have optimal runtime performance.

+config PS3_DYNAMIC_DMA
+       depends on PPC_PS3 && EXPERIMENTAL
+       bool "PS3 Platform dynamic DMA page table management"
+       default n
+       help
+         This option will enable kernel support to take advantage of the
+         per device dynamic DMA page table management provided by the Cell
+         processor's IO Controller.  This support incurs some runtime
+         overhead and also slightly increases kernel memory usage.  The
+         current implementation should be considered experimental.
+
+         This support is mainly for Linux kernel development.  If unsure,
+         say N.
+
+config PS3_USE_LPAR_ADDR
+       depends on PPC_PS3 && EXPERIMENTAL
+       bool "PS3 use lpar address space"
+       default y
+       help
+         This option is solely for experimentation by experts.  Disables
+         translation of lpar addresses.  SPE support currently won't work
+         without this set to y.
+
+         If you have any doubt, choose the default y.
+
+config PS3_VUART
+       depends on PPC_PS3
+       bool "PS3 Virtual UART support"
+       default y
+       help
+         Include support for the PS3 Virtual UART.
+
+         This support is required for several system services
+         including the System Manager and AV Settings.  In
+         general, all users will say Y.
