Hm, that second parameter to uvm_fault (0x10) is va (arch/amd64/amd64/ 
trap.c:489/517).
That va is trunc_page((vaddr_t)cr2) (arch/amd64/amd64/trap.c:459).

How on earth can this be 0x10?

I just double-checked my handwritten notes of the fault, and it's  
extremely
unlikely that I omitted several hex digits on that.
