1416 6569 d 9 h jermar /kernel/trunk/generic/ Make implementation of condition variables compliant with their definition.
Signal operation must become a no-op if there is no thread in the wait operation.
Remove condvar_trywait() which has no meaning after this change.		  
/kernel/trunk/generic/include/synch/condvar.h
/kernel/trunk/generic/src/synch/condvar.c
1415 6569 d 10 h jermar /kernel/trunk/generic/ Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount		  
/kernel/trunk/generic/include/mm/as.h
/kernel/trunk/generic/src/mm/as.c
1413 6569 d 21 h jermar /kernel/trunk/generic/ Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.

/kernel/trunk/generic/src/ipc/sysipc.c
/kernel/trunk/generic/src/mm/as.c
1411 6570 d 2 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.

1409 6570 d 20 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).

1387 6573 d 4 h jermar /kernel/trunk/generic/ Add used_space_insert() and used_space_remove().
These are the alpha versions of functions that
will help to map used and unused portions of address
space areas. Currently unused, but many as_area operations
will be more efficient when the used space B+tree map
is used.
