Pull printk updates from Petr Mladek: - Help userspace log daemons to catch up with a flood of messages. They will get woken 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. * tag 'printk-for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk: printk: drop in_nmi check from printk_safe_flush_on_panic() lib/vsprintf: Remove atomic-unsafe support for %pCr serial: sh-sci: Stop using printk format %pCr thermal: bcm2835: Stop using printk format %pCr clk: renesas: cpg-mssr: Stop using printk format %pCr printk: fix possible reuse of va_list variable printk: wake up klogd in vprintk_emit vsprintf: Tweak pF/pf comment lib/vsprintf: Mark expected switch fall-through lib/vsprintf: Replace space with '_' before crng is ready lib/vsprintf: Deduplicate pointer_string() lib/vsprintf: Move pointer_string() upper lib/vsprintf: Make flag_spec global lib/vsprintf: Make strspec global lib/vsprintf: Make dec_spec global lib/test_printf: Mark big constant with UL
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
