K 10 svn:author V 6 dillon K 8 svn:date V 27 1999-09-20T19:08:48.000000Z K 7 svn:log V 410 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. The fix is to have vm_fault_quick() return a success or failure which is then used to avoid calling pmap_kextract(). END
