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 drivers/rtc/rtc-vt8500.c: correct handling of CR_24H bitfield rtc: add RTC driver for TPS6586x MAINTAINERS: fix drivers/staging/sm7xx/ MAINTAINERS: remove include/linux/of_pwm.h MAINTAINERS: remove arch/*/lib/perf_event*.c MAINTAINERS: remove drivers/mmc/host/imxmmc.* MAINTAINERS: fix Documentation/mei/ MAINTAINERS: remove arch/x86/platform/mrst/pmu.* MAINTAINERS: remove firmware/isci/ MAINTAINERS: fix drivers/ieee802154/ MAINTAINERS: fix .../plat-mxc/include/mach/imxfb.h MAINTAINERS: remove drivers/video/epson1355fb.c MAINTAINERS: fix drivers/media/usb/dvb-usb/cxusb* MAINTAINERS: adjust for UAPI MAINTAINERS: fix drivers/media/platform/atmel-isi.c MAINTAINERS: fix arch/arm/mach-at91/include/mach/at_hdmac.h MAINTAINERS: fix drivers/rtc/rtc-vt8500.c MAINTAINERS: remove arch/arm/plat-s5p/ ...
