[GIT PULL] printk for 4.13

[Petr Mladek]

Linus,

please pull the latest printk changes from

  git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk.git for-linus


==========

- Store printk() messages into the main log buffer directly even in NMI
  when the lock is available. It is the best effort to print even large
  chunk of text. It is handy, for example, when all ftrace messages
  are printed during the system panic in NMI.

- Add missing annotations to calm down compiler warnings.

----------------------------------------------------------------

Nicolas Iooss (1):
      printk: add __printf attributes to internal functions

Petr Mladek (2):
      printk: Use the main logbuf in NMI when logbuf_lock is available
      Merge branch 'for-4.13' into for-linus
