Last change on this file since 1dbc43f was 22f0561, checked in by Jakub Jermar <jakub@…>, 14 years ago

Get rid of kernel static non-identity mappings on ia64.

  • IO_OFFSET is replaced by legacyio_virt_base and LEGACYIO_USER_BASE.
  • VIO_OFFSET and FW_OFFSET are removed entirely.
  • Legacy I/O and IO SAPIC are mapped via hw_map().
  • Remove corresponding locked translation records.
  • Cleanup ia64 kernel pio_read/write_8|16|32().
  • Property mode set to 100644
