Subject: [GIT pull] smp/core for v5.7

Linus,

please pull the latest smp/core branch from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git smp-core-2020-03-30

up to:  e98eac6ff1b4: cpu/hotplug: Ignore pm_wakeup_pending() for disable_nonboot_cpus()


CPU (hotplug) updates:

  - Support for locked CSD objects in smp_call_function_single_async()
    which allows to simplify callsites in the scheduler core and MIPS

  - Treewide consolidation of CPU hotplug functions which ensures the
    consistency between the sysfs interface and kernel state. The low level
    functions cpu_up/down() are now confined to the core code and not
    longer accessible from random code.

Thanks,

	tglx
