/* $NetBSD: main.h,v 1.6 2008/04/28 20:24:14 martin Exp $ */
Make pmap work on LOCKDEBUG *and* non-LOCKDEBUG kernels (previously it would fail in spectacular ways on LOCKDEBUG kernels) by compiling the groveler code twice (the second time with LOCKDEBUG defined so that the appropriate structures get larger in the right way). We currently decide if we are operating on a kernel with LOCKDEBUG enabled if the kernel's vm_map has referential integrity between a few pointers and/or values. Also, if you use more than one -v, you get a * on a line by itself in between gaps in entries. It makes finding gaps much easier visually.

Add the capability to dump the struct vm_amap and the am_anon, am_bckptr, am_slots, and am_anon data, if the vm_map_entry has an amap. This adds three new debug "bits" to the -D argument, so the namei cache dumping "bit" has been moved up. Also, change the * that gets emitted with -vv to indicate the number of pages skipped and the size of the area (in kilobytes).

Clean up code in places, add some more (possible) submap names, make better use of the submap names when dumping the kernel map, clean up the "interface" between the main and LOCKDEBUG dependent pmap modules, and make the heap identification work better.
