  Log:
  Improve ARM_TP_ADDRESS and RAS area.
  
  De-hardcode usage of ARM_TP_ADDRESS and RAS local storage, and move this
  special purpose page to a more convenient place i.e. after the vectors high
  page, more towards the end of address space. Previous location (0xe000_0000)
  caused grief if KVA was to go beyond the default limit.
  
  Note that ARM world rebuilding is required after this change since the
  location of ARM_TP_ADDRESS is shared between kernel and userland.
