Hi Colin, what system is this on?

The failing instruction should be a read of SPRG3:

   │0x3fffb7f807c8 <__kernel_getcpu> mfspr r5,259

which should be fine to execute in userspace. There was a NUMA_BALANCING bug around that time where we'd end up mapping the vdso no execute, but I don't think Ubuntu is enabling that feature.
