Hi Sandra,

As I told you earlier in the internal list, I'm shifting the start of
the .text location by one page on Nios2 Linux; I'm trying to not touch
the bare-metal nios2-elf config, so the logical thing to do is to
separate the emulations.

This is OK, but for the public record, can you explain more about themotivation for doing this? From what I recall of our internaldiscussion, it is because the new Linux kernel ABI needs to map someadditional system calls at a fixed address, but I'm not able to find thethread in my mailbox. :-(
