--------------------------------

commit fe76a1349f235969381832c83d703bc911021eb6 upstream.

Make sure that the __bug_table section gets 32- or 64-bit aligned,
depending if a 32- or 64-bit kernel is being built.
Mark it non-writeable and use .blockz instead of the .org assembler
directive to pad the struct.
