A few changes to make it possible to read UVM histories from userland:
...
- 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.
