There was an inverted boolean logic in determining how many consecutive pages were available. Also adding some memory debugging tools I added to track down the recent memory bugs: - A direct debugcon::write call, for logging to the debugcon without the possible page faults with the logger. - A new vm_space::lock call, to make a page not fillable in memory debugging mode - A mode in heap_allocator to always alloc new pages, and lock freed pages to cause page faults for use-after-free bugs. - Logging in kobject on creation and deletion - Page table cache structs are now page-sized for easy pointer math
