In addition to this warning I also got the following linker error when
CONFIG_IRQ_WORK=n:
kernel/built-in.o In function `wake_up_klogd':
(.text.wake_up_klogd+0xb4): undefined reference to `irq_work_queue'
which appears to be because of the following commit:
commit 74876a98a87a115254b3a66a14b27320b7f0acaa ("printk: Wake up klogd
using irq_work") also merged in v3.9-rc1.
Can somebody more familiar with that code please fix it.
Cheers
James
