Subject: [GIT PULL] printk for 6.14

Hi Linus,

please pull the latest printk changes from

  git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux.git tags/printk-for-6.14

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

- Prevent possible deadlocks, caused by the lock serializing per-CPU
  backtraces, by entering the deferred printk context.

- Enforce the right casting in LOG_BUF_LEN_MAX definition.

----------------------------------------------------------------
John Ogness (2):
      printk: Remove redundant deferred check in vprintk()
      printk: Defer legacy printing when holding printk_cpu_sync

Kuan-Wei Chiu (1):
      printk: Fix signed integer overflow when defining LOG_BUF_LEN_MAX

Petr Mladek (1):
      Merge branch 'for-6.14-cpu_sync-fixup' into for-linus
