Merge branch 'akpm' (fixes from Andrew)

Merge emailed fixes from Andrew Morton:
 "Bunch of fixes:

   - delayed IPC updates.  I held back on this because of some possible
     outstanding bug reports, but they appear to have been addressed in
     later versions

   - A bunch of MAINTAINERS updates

   - Yet Another RTC driver.  I'd held this back while a couple of
     little issues were being worked out.

  I'm expecting an intrusive-but-simple patchset from Joe Perches which
  splits up printk.c into kernel/printk/*.  That will be a pig to
  maintain for two months so if it passes testing I'd like to get it
  upstream after a week or so."

+These three toggles allows to specify desired id for next allocated IPC

+By default they are equal to -1, which means generic allocation logic.
+Possible values to set are in range {0..INT_MAX}.

+Notes:
+1) kernel doesn't guarantee, that new object will have desired id. So,

+2) Toggle with non-default value will be set back to -1 by kernel after
