The fix is to have vm_fault_quick() return a success or failure which is then used to avoid calling pmap_kextract(). diff 4cc712004cbc472b5ff93761b1ecbb724b6f44a1 Mon Sep 20 21:08:48 CEST 1999 Matthew Dillon <dillon@FreeBSD.org> Fix bug in pipe code relating to writes of mmap'd but illegal address spaces which cross a segment boundry in the page table. pmap_kextract() is not designed for access to the user space portion of the page table and cannot handle the null-page-directory-entry case.
