Subject[GIT PULL] printk for 4.18
Linus,

please pull the latest printk changes from

git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk tags/printk-for-4.18

There will be conflicts in lib/vsprintf.c that are caused by late fixes for
4.17. The proposed resolution can be found in the branch

git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk.git for-4.18-vsprintf-conflict

Also I am sorry that I have rebased today. I added one late ack and
removed one fix that was not good enough. I found a race in that fix
when writing this summary.

==============

- Help userspace log daemons to catch up with a flood of messages. They
will get waken after each message even if the console is far behind and
handled by another process.

- Flush printk safe buffers safely even when panic() happens in the normal
context.

- Fix possible va_list reuse when race happened in printk_safe().

- Remove %pCr printf format to prevent sleeping in the atomic context.

- Misc vsprintf code cleanup.
