Similar tests with start address five or six bytes before the start of 
the unmapped page, and corresponding path length to be returned by 
getcwd have shown no more Oops on 030 using the attached corrected 
version of my patch.

Please give that some testing if you can, and (hoping it won't show any 
new faults on 040) I'll post another version of the series with your 
Tested-by added.

Cheers,
