- Enable this option if you want to enable real IOREMAPPING on PA-RISC.
- Currently we just "simulate" I/O remapping, and enabling this option
- will just crash your machine.
+ This lets you select the page size of the kernel. For best
+ performance, a page size of 16KB is recommended. For best
+ compatibility with 32bit applications, a page size of 4KB should be
+ selected (the vast majority of 32bit binaries work perfectly fine
+ with a larger page size).
+
+ 4KB For best 32bit compatibility
+ 16KB For best performance
+ 64KB For best performance, might give more overhead.
+
+ If you don't know what to do, choose 4KB.
