Linus,
please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk.git for-linus
to receive printk queue for 4.11 merge window:
==========
- Add Petr Mladek, Sergey Senozhatsky as printk maintainers,
and Steven Rostedt as the printk reviewer. This idea came up
after the discussion about printk issues at Kernel Summit.
It was formulated and discussed at lkml[1].
- Extend a lock-less NMI per-cpu buffers idea to handle recursive
printk() calls by Sergey Senozhatsky[2]. It is the first step
in sanitizing printk as discussed at Kernel Summit.
The change allows to see messages that would normally get ignored
or would cause a deadlock.
Also it allows to enable lockdep in printk(). This already paid
off. The testing in linux-next helped to discover two old
problems that were hidden before[3][4].
- Remove unused parameter by Sergey Senozhatsky. Clean up
after a past change.

Hmm. Please use -M when generating diffstats, because what I got is:
11 files changed, 347 insertions(+), 255 deletions(-)
rename kernel/printk/{nmi.c => printk_safe.c} (53%)
which is more descriptive of what actually is going on.
The default pull-request script uses -M, so I don't know why you
didn't have that already.
