1104 6677 d 12 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.		  
1080 6682 d 11 h jermar /kernel/trunk/arch/ia64/src/mm/ Fix double page_table_unlock() in ia64 tlb.c.  
1078 6682 d 11 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1070 6682 d 19 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1066 6683 d 4 h jermar /kernel/trunk/ Support for user space threads.
