+ help
+ Selecting this option will enable the extended mode of the SH-X2
+ TLB. For legacy SH-X behaviour and interoperability, say N. For
+ all of the fun new features and a willingless to submit bug reports,
+ say Y.

+config VSYSCALL
+ bool "Support vsyscall page"
+ depends on MMU
+ default y
+ help
+ This will enable support for the kernel mapping a vDSO page
+ in process space, and subsequently handing down the entry point
+ to the libc through the ELF auxiliary vector.
+
+ From the kernel side this is used for the signal trampoline.
+ For systems with an MMU that can afford to give up a page,
+ (the default value) say Y.

+ help
+ This is the default page size used by all SuperH CPUs.
+
+config PAGE_SIZE_8KB
+ bool "8kB"
+ depends on EXPERIMENTAL && X2TLB
+ help
+ This enables 8kB pages as supported by SH-X2 and later MMUs.
+
+config PAGE_SIZE_64KB
+ bool "64kB"
+ depends on EXPERIMENTAL && CPU_SH4
+ help
+ This enables support for 64kB pages, possible on all SH-4
+ CPUs and later. Highly experimental, not recommended.
