[PATCH v7 0/3] Drivers: hv: vmbus: use cpu_hotplug_enable/disable for CPU offlining prevention

[Vitaly Kuznetsov <vkuznets@redhat.com>]

Changes since v6:
- Rearrange patches. [Thomas Gleixner]
- Fix a typo in PATCH 2 description [Thomas Gleixner].
- Add Reviewed-by: [Thomas Gleixner].

Changes since v5:
- Split PATCH 1 into two (PATCH 1/3 and 3/3), rewrite changelogs. [Thomas
  Gleixner]

Changes since v4:
- In disable_nonboot_cpus() do cpu_hotplug_disabled++ unconditionally as
  its users are doing enable_nonboot_cpus() on their failure paths.

Changes since v3:
- add WARN_ON when decreasing cpu_hotplug_disabled [Peter Zijlstra]

Changes since v2:
- Rebase on top of current Greg's char-misc-next tree [K. Y. Srinivasan]

Changes since v1:
- Make cpu_hotplug_disabled a counter [Radim Krčmář]

Export cpu_hotplug_enable/cpu_hotplug_disable functions from cpu.c and use
them instead of altering smp_ops.cpu_disable in Hyper-V vmbus module.

Vitaly Kuznetsov (3):
  cpu-hotplug: convert cpu_hotplug_disabled to a counter
  cpu-hotplug: export cpu_hotplug_enable/cpu_hotplug_disable
  Drivers: hv: vmbus: use cpu_hotplug_enable/disable
