    [PATCH] make local_t signed · 2cf8d82d
    Andrew Morton authored
    local_t's were defined to be unsigned.  This increases confusion because
    atomic_t's are signed.  The patch goes through and changes all implementations
    to use signed longs throughout.
    
    Also, x86-64 was using 32-bit quantities for the value passed into local_add()
    and local_sub().  Fixed.
    
    All (actually, both) existing users have been audited.
