Previously virt_to_phys/phys_to_virt macros were used such that they did a blind offset translation for creating a pager internal virtual address for user mappings. This is now changed such that a properly bookkeeped virtual address pool is used which will avoid any clashes on the virtual space.

MM0 TODO List:
|
|
|
|
1.) Bootmem needs to be freed.
|
|
2.) Virtual memory regions available as capabilities need to be dynamically
|
|
allocated to various purposes, i.e. task region, shared memory region,
|
|
utcb region, etc. by traversing each region and matching to purposes.
|
|
3.) virt_to_phys()/phys_to_virt() uses the fixed offset of INITTASK_OFFSET, this
|
|
either needs to be discovered at run-time or specified at config-time.
|
|
4.) pager_new_address()/pager_delete_address() needs to use a region inside
|
|
pager start/end regions, and virt_to_phys()/phys_to_virt() should not clash
|
|
with those regions.
|
|
5.) read_file_pages()/write_file_pages() needs to be tested and improved in
|
|
terms of syscalls to microkernel.
