Re: [PATCH] 8xx: fix usage of pinned 8Mbyte TLB entries

The BDI can, but other software functions will walk the page
tables looking for PTE information.  

Do you have any practical example which you are certain is going
to break? 

I think the BDM4GDB BDM debugger depends  on  this,  and  maybe  some
other tools, too.

I dont remember any, and I dont think any software should be walking
kernel pte's directly...

Maybe not regular software, but debug tools  that  live  outside  the
kernel.

Testing can show the presense of bugs, but not their absence.
