This first patch contains the changes to arch/{s390,s390x}

Many Makefiles did a put an own rule in front of 
"include $(TOPDIR)/Rules.make" for no good reason at all,
the only places where it made sense are converted to using
EXTRA_TARGETS now.

  - Tim Waugh: fix up parport wrong #define
  - Christoph Hellwig: i2c update, ext2 cleanup
  - Al Viro: fix partition handling sanity check.
  - Trond Myklebust: make NFS use SLAB_NOFS, and not play games with PF_MEMALLOC
  - Ben Fennema: UDF update
  - Alan Cox: continued merging
  - Chris Mason: get /proc buffer memory sizes right after buf-in-page-cache

  - Ingo Molnar/Al Viro: don't use bforget() on ext2 (and minix) metadata
  where we may not be the only owner of the buffer! FS corruption.
