Petr Mladek 9a4ad8a725 printk: Prepare for nested printk_nmi_enter() ... commit 2ade0d6093 upstream. There is plenty of space in the printk_context variable. Reserve one byte there for the NMI context to be on the safe side. It should never overflow. The BUG_ON(in_nmi() == NMI_MASK) in nmi_enter() will trigger much earlier. Intel-SIG: commit 2ade0d6093 printk: Prepare for nested printk_nmi_enter(). Backport to kernel 5.4 to enhance MCA-R.
