Since all userspace apps are using 64K pages these days it makes sense to set the default large page size to 64K. This in turn causes the PDE coverage field to be set to 64M in the GPU characteristics field. While it would therefor be possible to create a VM with a PDE coverage that's larger than 64M (128M if you set the large page size to 128K) this will make the defaults work properly. This in turn fixes a CUDA issue where CUDA tries to determine the PDE coverage (and correspondingly a minimum alignemnt) from the characteristics IOCTL.
