Hi, Laurent,

Here is a mini-series about a MIPS-specific linux-user feature. Its code is 
almost entirely either in MIPS-specific files or under "#ifdef MIPS" 
directives. I think it makes sense that I should be able to integrate them via 
MIPS queue. Please let me know if you object to this.

You probably wonder why so much code for such obscure feature. The answer is 
that the solution needs to follow and mimic corresponding solution in 
MIPS-specific parts of the kernel, and its complexity is determined by that.

Thanks,
Aleksandar
