The following commit in 4.18.y causes the build to fail:
79764192e1c4 ("printk/nmi: Prevent deadlock when accessing the main log buffer in NMI")
with:
| kernel/printk/printk_safe.o: In function `vprintk_func':
| printk_safe.c:(.text+0x51b): undefined reference to `vprintk_store'
| printk_safe.c:(.text+0x52f): undefined reference to `defer_console_output'
Picking up these from mainline seems to do the trick:
a338f84dc196 ("printk: Create helper function to queue deferred console handling")
ba552399954d ("printk: Split the code for storing a message into the log buffer")
Thanks,
Dan

Sorry, I'll fix this up, my fault.
