histories to merge in cronological order. currently, MAPHIST and
PDHIST are defined as 1 and 2 respectively. passing a bitmask of 0
to uvm_hist() will dump all maps.
- Protect option headers from inclusion if ! _KERNEL or if _LKM.
- Make sure struct uvm_history is always the same size (not dependent
on NCPU).
- Add fmtlen and fnlen members to struct uvm_history_ent, which specify
the lengths fo the fmt and fn strings.
- Add name, namelen, and a list entry to struct uvm_history.
- When a history is initialized, place it on the global list of all histories.
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. :-)
