Hi Andrew,
Today's linux-next merge of the akpm tree got a conflict in
kernel/posix-cpu-timers.c between commits a85721601ad2 ("posix_timers:
Kick full dynticks CPUs when a posix cpu timer is armed") and
555347f6c080 ("posix_timers: New API to prevent from stopping the tick
when timers are running") from the tip tree and commit "posix_cpu_timer:
consolidate expiry time type" from the akpm tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
