Only the line change in kfree is included ... not the paranoid save_flags :)
... and it seems that some of the changes in drivers/char/ causes troubel.
And there was a GP in sys_uselib ...
Nevertheless ... the message "Virtual memory exhausted" is _really_ better
than "Couldn't get a free page" ... All those seeing noe the first message
should do a `grep Couldn /var/log/message'
