Yes. This is the output from that function, running a 9.2 kernel (called from within newcpu_common.c when the SRP is set):

 

srp=0132c000 tcr=00000000

MMU dump start. Root = 0132c000. Page = 8192

ff1fe000 - ff1fffff: 01330000 WP=0 S=0 CM=2 (01330041)

ff200000 - ffffffff: 00000000 WP=0 S=0 CM=0 (00000000)

MMU dump end

 

And this is the output from the old function:

In the 2nd output you see that virtual addresses >= ff200000 are not mapped at all. The first output incorrectly prints them as being mapped to 0
