soft lockup when passing vvar address to write(2)

Looking up the vvar mapping and dumping its contents sometimes results in a soft lockup. On 4.5-rc6+ (master from earlier today) it seems to be a little harder to trigger than on the 4.2something Ubuntu kernel I first saw it on, but in both cases it's easy to reproduce (10s of iterations at most)
