#     
#     Pull XArray fixes from Matthew Wilcox:
#      "Fix some oversights in the XArray porcelain API:
#     
#        - support for m68k's two-byte aligned pointers
#     
#        - reserving entries using xa_insert()
#     
#        - missing xa_insert_bh() and xa_insert_irq() functions
#     
#        - simplify using xa_for_each()
#     
#        - use lockdep correctly
#     
#        - a few other minor fixes and improvements"
