Subject: [GIT PULL] printk for 5.20

Hi Linus,

please pull the latest printk changes from

  git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux.git tags/printk-for-5.20

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

- Completely disable printing on consoles with CONFIG_RT. They break
  RT guarantees. They are too slow to be called with raw spinlocks.
  They can't be called with normal spinlocks in an atomic context because
  RT spinlocks might sleep. It is going to get fixed by the kthreads and
  atomic consoles. In the meantime, the debugging of CONFIG_RT kernel
  will be possible only by the user space kernel log readers.

- Allow to read kernel log in gdb even on 32 bits systems.

- More granular check of the buffer usage in printf selftest.

- Clang warning fix.
