+#config SGI_SN0_XXL
+# bool "IP27 XXL"
+# depends on SGI_IP27
+# This options adds support for userspace processes upto 16TB size.
+# Normally the limit is just .5TB.

+config SGI_SN0_N_MODE
+ bool "IP27 N-Mode"
+ depends on SGI_IP27
+ help
+ The nodes of Origin 200, Origin 2000 and Onyx 2 systems can be
+ configured in either N-Modes which allows for more nodes or M-Mode
+ which allows for more memory. Your system is most probably
+ running in M-Mode, so you should say N here.
+
+config ARCH_DISCONTIGMEM_ENABLE
+ bool
+ default y if SGI_IP27
+ help
+ Say Y to upport efficient handling of discontiguous physical memory,
+ for architectures which are either NUMA (Non-Uniform Memory Access)
+ or have huge holes in the physical address space for other reasons.
+ See <file:Documentation/vm/numa> for more.
+
+config NUMA
+ bool "NUMA Support"
+ depends on SGI_IP27
+ help
+ Say Y to compile the kernel to support NUMA (Non-Uniform Memory
+ Access). This option is for configuring high-end multiprocessor
+ server machines. If in doubt, say N.
+
+config MAPPED_KERNEL
+ bool "Mapped kernel support"
+ depends on SGI_IP27
+ help
+ Change the way a Linux kernel is loaded into memory on a MIPS64
+ machine. This is required in order to support text replication and
+ NUMA. If you need to understand it, read the source code.
+
+config REPLICATE_KTEXT
+ bool "Kernel text replication support"
+ depends on SGI_IP27
+ help
+ Say Y here to enable replicating the kernel text across multiple
+ nodes in a NUMA cluster. This trades memory for speed.
+
+config REPLICATE_EXHANDLERS
+ bool "Exception handler replication support"
+ depends on SGI_IP27
+ help
+ Say Y here to enable replicating the kernel exception handlers
+ across multiple nodes in a NUMA cluster. This trades memory for
+ speed.
