Did you test it ? I have a vague memory that using spl() in early
allocation routines would cause a trap (maybe because curcpu() doesn't
work yet) but maybe your recent changes fixed it.
Also you can change
#ifndef XEN
const pd_entry_t pteflags = PG_V | PG_RW;
#else /* XEN */
const pd_entry_t pteflags = PG_u | PG_V | PG_RW;
#endif /* XEN */
to:
const pd_entry_t pteflags = PG_k | PG_V | PG_RW;
(PG_k is defined to PG_u on Xen/amd64 and 0 otherwise).
