* Fixed tracing build.

Browse Source 
* In reserve_boot_loader_ranges() we skip ranges that lie without
  the kernel address space (we failed and panic()ed before). The
  architecture specific code has to deal with those, if they are
  of any importance.
* sAvailableMemoryLock.sem was not set to -1 in vm_init() so code
  executed after semaphores were available but before the semaphore
  was created caused semaphore 0 to be acquired.
