no atomic_set/clear_mask

I see ia64 doesn't have atomic_set_mask() and atomic_clear_mask() 
functions.  I'm trying to deal with a page->flags corruption issue (not 
yet seen on IA-64, but there's no reason it couldn't be) where page->flags 
gets modified nonatomically while another CPU modifies individual bits 
atomically with set_bit() or clear_bit().

Would anyone like to take a stab at providing atomic_set_mask and 
atomic_clear_mask functions for IA64? :-)
