DRM-current-kmod is still a problem at r353339

List:

I am still getting kernel panics on my laptop after the recent changes
made to /sys/amd64/amd64/pmap.c.

The updated pmap.c works on my Skylake build machine but panics on my
laptop.  I always build on the faster computer and perform a
installkernel and installworld from a nfs share.  The Skylake is much
faster than the laptop.  The hardware info from dmesg:
