Pull CPU hotplug updates from Thomas Gleixner:
"Yet another batch of cpu hotplug core updates and conversions:
- Provide core infrastructure for multi instance drivers so the
drivers do not have to keep custom lists.
- Convert custom lists to the new infrastructure. The block-mq custom
list conversion comes through the block tree and makes the diffstat
tip over to more lines removed than added.
- Handle unbalanced hotplug enable/disable calls more gracefully.
- Remove the obsolete CPU_STARTING/DYING notifier support.
- Convert another batch of notifier users.
The relayfs changes which conflicted with the conversion have been
shipped to me by Andrew.
The remaining lot is targeted for 4.10 so that we finally can remove
the rest of the notifiers"

This patch only reserves two CPU hotplug states for block/mq so the block tree
can apply the conversion patches.

Install the callbacks via the state machine.
This is just a temporary vehicle to keep the interface working for now,
It'll be replaced by the sysfs interface which allows to step through the
hotplug state machine step by step.

Install the callbacks via the state machine. It uses the multi instance
infrastructure of the hotplug code to handle each interface.
virtscsi_set_affinity() is removed from virtscsi_init() because
virtscsi_cpu_notif_add() (the function which registers the instance) is invoked
right after it and the cpuhp_state_add_instance() functions invokes the startup
callback on all online CPUs.
The same thing can not be applied virtscsi_cpu_notif_remove() because
virtscsi_remove_vqs() invokes virtscsi_set_affinity() with affinity = false as
argument but the old CPU_DEAD state invoked the function with affinity = true
(which does not match the DEAD callback).

Install the callbacks via the state machine.
I assume here that the powermac has two CPUs and so only one can go up
or down at a time. The variable smp_core99_host_open is here to ensure
that we do not try to open or close the i2c host twice if something goes
wrong and we invoke the prepare or online callback twice due to
rollback.

Install the callbacks via the state machine.
The driver supports multiple instances and therefore the new
cpuhp_state_add_instance_nocalls() infrastrucure is used. The driver
currently uses get_online_cpus() to avoid missing a CPU hotplug event while
invoking virtnet_set_affinity(). This could be avoided by using
cpuhp_state_add_instance() variant which holds the hotplug lock and invokes
callback during registration. This is more or less a 1:1 conversion of the
current code.

This patch adds the ability for a given state to have multiple
instances. Until now all states have a single instance and the startup /
teardown callback use global variables.
A few drivers need to perform a the same callbacks on multiple
"instances". Currently we have three drivers in tree which all have a
global list which they iterate over. With multi instance they support
don't need their private list and the functionality has been moved into
core code. Plus we hold the hotplug lock in core so no cpus comes/goes
while instances are registered and we do rollback in error case :)

Pull arm64 updates from Will Deacon:
"It's a bit all over the place this time with no "killer feature" to
speak of. Support for mismatched cache line sizes should help people
seeing whacky JIT failures on some SoCs, and the big.LITTLE perf
updates have been a long time coming, but a lot of the changes here
are cleanups.
We stray outside arch/arm64 in a few areas: the arch/arm/ arch_timer
workaround is acked by Russell, the DT/OF bits are acked by Rob, the
arch_timer clocksource changes acked by Marc, CPU hotplug by tglx and
jump_label by Peter (all CC'd).
Summary:
- Support for execute-only page permissions
- Support for hibernate and DEBUG_PAGEALLOC
- Support for heterogeneous systems with mismatches cache line sizes
- Errata workarounds (A53 843419 update and QorIQ A-008585 timer bug)
- arm64 PMU perf updates, including cpumasks for heterogeneous systems
- Set UTS_MACHINE for building rpm packages
- Yet another head.S tidy-up
- Some cleanups and refactoring, particularly in the NUMA code
- Lots of random, non-critical fixes across the board"

The arm64 hw_breakpoint implementation uses a CPU hotplug notifier to
reset the {break,watch}point registers when CPUs come online.
This patch converts the code to the new hotplug mechanism, whilst moving
the invocation earlier to remove the need to disable IRQs explicitly in
the driver (which could cause havok if we trip a watchpoint in an IRQ
handler whilst restoring the debug register state).

including linux/types.h to ensure that type has been defined. Fix this

On the tear-down path, the dead CPU callback for the timers was
misplaced within the 'cpuhp_state' enumeration. There is a hidden
dependency between the timers and block multiqueue. The timers
callback must happen before the block multiqueue callback otherwise a
RCU stall occurs.
Move the timers callback to the proper place in the state machine.

There is no need the ledtriger to be called *that* early in the hotplug
process (+ with disabled interrupts). As explained by Jacek Anaszewski [0]
there is no need for it.
Therefore this patch moves it to the ONLINE/PREPARE_DOWN level using the
dynamic registration for the id.

When tearing down, call timers_dead_cpu() before notify_dead().
There is a hidden dependency between:
- timers
- block multiqueue
- rcutree
If timers_dead_cpu() comes later than blk_mq_queue_reinit_notify()
that latter function causes a RCU stall.
