If the base clock is behind jiffies in the soft irq expiry code then the
next timer is retrieved by get_next_timer_interrupt() to avoid incrementing
base clock one by one. If the next timer interrupt is past current jiffies
then the base clock is set to jiffies - 1. At the call site this is
incremented and another iteration through the expiry loop is executed which
checks empty hash buckets.
That's a pointless excercise because it's already known that the next timer
is past jiffies.
Set the base clock in that case to jiffies directly so it gets incremented
to jiffies + 1 at the call site resulting in immediate termination of the
expiry loop.

Pull cgroup fix from Tejun Heo:
"The recent migration code updates assumed that migrations always
execute from the top to the bottom once and didn't clean up internal
states after each migration round; however, cgroup_transfer_tasks()
repeats the inner steps multiple times and the garbage internal states
from the previous iteration led to OOPS.
Waiman fixed the bug by reinitializing the relevant states at the end
of each migration round"

Pull percpu fixes from Tejun Heo:
"Rather important fixes this time.
- The new percpu area allocator had a subtle bug in how it iterates
the memory regions and could skip viable areas, which led to
allocation failures for module static percpu variables. Dennis
fixed the bug and another non-critical one in stat calculation.
- Mark noticed that the generic implementations of percpu local
atomic reads aren't properly protected against irqs and there's a
(slim) chance for split reads on some 32bit systems. Generic
implementations are updated to disable irq when read size is larger
than ulong size. This may have made some 32bit archs which can do
atomic local 64bit accesses generate sub-optimal code. We need to
find them out and implement arch-specific overrides"

"Here are a few small fixes for 4.14-rc4.
The removal of DRIVER_ATTR() was almost completed by 4.14-rc1, but one
straggler made it in through some other tree (odds are, one of
mine...) So there's a simple removal of the last user, and then
finally the macro is removed from the tree.
There's a fix for old crazy udev instances that insist on reloading a
module when it is removed from the kernel due to the new uevents for
bind/unbind. This fixes the reported regression, hopefully some year
in the future we can drop the workaround, once users update to the
latest version, but I'm not holding my breath.
And then there's a build fix for a linker warning, and a buffer
overflow fix to match the PCI fixes you took through the PCI tree in
the same area.

Pull timer fixes from Thomas Gleixner:
"This adds a new timer wheel function which is required for the
conversion of the timer callback function from the 'unsigned long
data' argument to 'struct timer_list *timer'. This conversion has two
benefits:
1) It makes struct timer_list smaller
2) Many callers hand in a pointer to the timer or to the structure
containing the timer, which happens via type casting both at setup
and in the callback. This change gets rid of the typecasts.
Once the conversion is complete, which is planned for 4.15, the old
setup function and the intermediate typecast in the new setup function
go away along with the data field in struct timer_list.
Merging this now into mainline allows a smooth queueing of the actual
conversion in the affected maintainer trees without creating
dependencies"
