thorpej 12347b2657 Make uvm_vslock() return the error code from uvm_fault_wire(). All places
which use uvm_vslock() should now test the return value.  If it's not
KERN_SUCCESS, wiring the pages failed, so the operation which is using
uvm_vslock() should error out.

XXX We currently just EFAULT a failed uvm_vslock().  We may want to do
more about translating error codes in the future.

thorpej 497248ca55 XXX Pass VM_PROT_NONE to uvm_vslock() as access_type. Why are we even
vslocking here?!  copyout() on its own seems to suffice just about everwhere
else, and it's not like the process is going to exit; it's in a system
call!

drochner 192b3c733c Build libraries for kernel/standalone code from within their compilation
directories and use .PATH to lookup the source files.
(Formerly, the libs were built from the source dirs, with MAKEOBJDIR
set to the compilation directory.)
This solves 2 problems:
-"mkdep" and "make" are now consistent about the file lookup, this fixes
 bad interactions with amd reported in PR bin/7374 (Arne Juul) and
 lossage reported by Andrew Gillham ("obj" dirs and relative paths still
 don't work well together)
-kernel compile trees can be moved around without forcing a new
 "make depend" - fixing PR kern/4021 by Martin Husemann

thorpej e3669c3393 Add "use counting" to file entries. When closing a file, and it's reference
count is 0, wait for use count to drain before finishing the close.

This is necessary in order for multiple processes to safely share file
descriptor tables.
