Last change on this file since 3d2d2fc2 was ef67bab, checked in by Jakub Jermar <jakub@…>, 20 years ago

Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
