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."

* emailed patches from Andrew Morton <akpm@linux-foundation.org>: (35 commits)
  printk: fix incorrect length from print_time() when seconds > 99999
  drivers/rtc/rtc-vt8500.c: fix handling of data passed in struct rtc_time

msg_next_id, sem_next_id, and shm_next_id:
These three toggles allows to specify desired id for next allocated IPC
object: message, semaphore or shared memory respectively.
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,
it's up to userspace, how to handle an object with "wrong" id.
2) Toggle with non-default value will be set back to -1 by kernel after
successful IPC object allocation.

shmall:
This parameter sets the total amount of shared memory pages that
can be used system wide. Hence, SHMALL should always be at least
ceil(shmmax/PAGE_SIZE).
If you are not sure what the default PAGE_SIZE is on your Linux
system, you can run the following command:
