svn commit: r259419 - projects/altix2/sys/sparc64/include

New Revision: 259419

Log:
  Bump BUS_SPACE_MAXADDR from 2^31-1 to 2^64-1. The bus_dma compat layer
  panics, because it checks that the maximum address passed to
  bus_dma_tag_create() matches BUS_SPACE_MAXADDR and finds that it doesn't
  for psycho(4). The psycho(4) driver passes ~0 and not BUS_SPACE_MAXADDR.
  sparc64 is a 64-bit archirecture, so why isn't BUS_SPACE_MAXADDR 2^61-1?
  
  I'm probably groing to regret this change, but so far it doesn't look
  like it's having any negative side-effects.
  
  While here, postfix U and UL to the BUS_SPACE constants.
