Somehow I ended up with an off-by-three error in calculating the size of the PASID and PASID State tables, which triggers allocations failures as those tables unfortunately have to be physically contiguous. In fact, even the *correct* maximum size of 8MiB is problematic and is wont to lead to allocation failures. Since I have extracted a promise that this *will* be fixed in hardware, I'm happy to limit it on the current hardware to a maximum of 0x20000 PASIDs, which gives us 1MiB tables — still not ideal, but better than before. Reported by Mika Kuoppala <mika.kuoppala@linux.intel.com> and also by Xunlei Pang <xlpang@redhat.com> who submitted a simpler patch to fix only the allocation (and not the free) to the "correct" limit... which was still problematic.
