Hi all,
Today's linux-next merge of the percpu tree got a conflict in
kernel/irq_work.c between commit 76a33061b932 ("irq_work: Force raised
irq work to run on irq work interrupt") from the tip tree and commit
22127e93c587 ("time: Replace __get_cpu_var uses") from the percpu tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
