Re: powerpc/mm: Add a parameter to disable 1TB segs

This patch adds the kernel command line parameter "no_tb_segs" which

of 256MB segments makes it considerably easier to test code that depends
on an SLB miss occurring.

That's a fairly awful name :)

Can you call it "disable_1T_segments" ?

It should also be mentioned in Documentation/kernel-parameters.txt, with
emphasis that it's a debug option and powerpc only.
