- break anon related functions out of uvm_amap.c and put them in their own
file (uvm_anon.c). includes break up uvm_anon_init into an amap and an
an anon init function
- ensure that only functions within the amap module access amap structure
fields (add macros to amap api as needed)
- simplify uvm_faultinfo in uvm_fault.h (parent map tracking no longer needed)
- adjust locking and lookup functions in uvm_fault_i.h to reflect the above
- replace ufi.rvaddr with ufi.orig_rvaddr in uvm_fault.c since rvaddr is
no longer needed.
- no need to worry about share map translations in uvm_fault(). simplify.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code. i provided some help
getting swap and paging working, and other bug fixes/ideas. chuck
silvers <chuq@chuq.com> also provided some other fixes.
this is the UVM kernel code portion.
this will be KNF'd shortly. :-)
