Merge Andrew's first set of patches:
"Non-MM patches:
- lots of misc bits
- tree-wide have_clk() cleanups
- quite a lot of printk tweaks. I draw your attention to "printk:
convert the format for KERN_<LEVEL> to a 2 byte pattern" which
looks a bit scary. But afaict it's solid.
- backlight updates
- lib/ feature work (notably the addition and use of memweight())
- checkpatch updates
- rtc updates
- nilfs updates
- fatfs updates (partial, still waiting for acks)
- kdump, proc, fork, IPC, sysctl, taskstats, pps, etc
- new fault-injection feature work"
* Merge emailed patches from Andrew Morton <akpm@linux-foundation.org>: (128 commits)
