well the bug I recieved looked like it had to do with highmem and this was the only code relating to mem that got touched, as for the other person, their crash was reproducible and it definitely was an oops, numlock led started to blink and system was unresponsive, for both of us reverting this change seems fix the issue, my dmesg log is attached to this message
