dabc448c4e Added freeing of pager init memory, but this memory is currently not utilized. 2009-08-19 16:26:44 +03:00

9c03d57d63 Carried over pager's virtual address alloc range to its own address space area. 2009-08-19 15:18:10 +03:00
Bahadir Balban
95b7b65c89 Pager virtual address pool bookkeeping added for all pager virtual addresses 
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.

c64c1a4515 MM0 do_close() without IO was segfaulting. now fixed. 
This was triggered by incorrect test0 build that omits to embed
the test executable.
