    [IA64] Fix rwsem: RWSEM_WAITING_BIAS must not be unsigned. · b680f097
    Tony Luck 提交于
    Some nice improvements were made to rwsem in commit:
    
     424acaae
     rwsem: wake queued readers when writer blocks on active read lock
    
    but this change overlooked that ia64 had defined RWSEM_WAITING_BIAS
    as an unsigned value, while the new code required a signed value (as
    it is in every other architecture).
    
    This fix suggested by the original patch author: Michel Lespinasse.
