Do you have a backtrace for the failure case? I have no problem
applying this part of the patch (I really don't understand why x86-64
hadn't gotten the proper code from 32-bit), but I'd like to see (and
document) where the fault happens for this.
Since you can apparently reproduce this fairly easily with a broken
kernel, getting a backtrace shouldn't be too hard?
