Subject: [GIT PULL] printk for 6.15

Hi Linus,

please pull the latest printk changes from

  git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux.git tags/printk-for-6.15

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

- New option "printk.debug_non_panic_cpus" allows to store printk
  messages from non-panic CPUs during panic. It might be useful
  when panic() fails. It is disabled by default because it increases
  the chance to see the messages printed before panic() and on
  the panic-CPU.

- New build option "CONFIG_NULL_TTY_DEFAULT_CONSOLE" allows to build
  kernel without the virtual terminal support which prefers ttynull
  over serial console.

- Do not unblank suspended consoles.

- Some code clean up.

----------------------------------------------------------------
Adam Simonelli (1):
      printk: Add an option to allow ttynull to be a default console device

Donghyeok Choe (1):
      printk/panic: Add option to allow non-panic CPUs to write to the ring buffer.

Marcos Paulo de Souza (5):
      printk: Rename suspend_console to console_suspend_all
      printk: Rename resume_console to console_resume_all
      printk: Rename console_stop to console_suspend
      printk: Rename console_start to console_resume
      printk: Check CON_SUSPEND when unblanking a console

Petr Mladek (1):
      Merge branch 'for-6.15-console-suspend-api-cleanup' into for-linus
