      reboot: rigrate shutdown/reboot to boot cpu · cf7df378
      Robin Holt authored
      We recently noticed that reboot of a 1024 cpu machine takes approx 16
      minutes of just stopping the cpus.  The slowdown was tracked to commit
       ("kernel/sys.c: call disable_nonboot_cpus() in
      The current implementation does all the work of hot removing the cpus
      before halting the system.  We are switching to just migrating to the
      boot cpu and then continuing with shutdown/reboot.
      This also has the effect of not breaking x86's command line parameter
      for specifying the reboot cpu.  Note, this code was shamelessly copied
      from arch/x86/kernel/reboot.c with bits removed pertaining to the
      reboot_cpu command line parameter.

      CPU hotplug: provide a generic helper to disable/enable CPU hotplug · 16e53dbf
      Srivatsa S. Bhat authored
      There are instances in the kernel where we would like to disable CPU
      hotplug (from sysfs) during some important operation.  Today the freezer
      code depends on this and the code to do it was kinda tailor-made for
      Restructure the code and make it generic enough to be useful for other
      usecases too.

      Fix lockup related to stop_machine being stuck in __do_softirq. · 34376a50
      Ben Greear authored
      The stop machine logic can lock up if all but one of the migration
      threads make it through the disable-irq step and the one remaining
      thread gets stuck in __do_softirq.  The reason __do_softirq can hang is
      that it has a bail-out based on jiffies timeout, but in the lockup case,
      jiffies itself is not incremented.
      To work around this, re-add the max_restart counter in __do_irq and stop
      processing irqs after 10 restarts.

      this down.

      xen/tmem: Don't over-write tmem_frontswap_poolid after tmem_frontswap_init set it. · b2c75c44
      Konrad Rzeszutek Wilk authored
      Commit 10a7a077 ("xen: tmem: enable Xen
      tmem shim to be built/loaded as a module") allows the tmem module
      to be loaded any time. For this work the frontswap API had to
      be able to asynchronously to call tmem_frontswap_init before
      or after the swap image had been set. That was added in git
      commit 905cd0e1
      ("mm: frontswap: lazy initialization to allow tmem backends to build/run as modules").
      Which means we could do this (The common case):
       modprobe tmem		[so calls frontswap_register_ops, no ->init]
      			 modifies tmem_frontswap_poolid = -1
       swapon /dev/xvda1	[__frontswap_init, calls -> init, tmem_frontswap_poolid is
      			 < 0 so tmem hypercall done]
      Or the failing one:
       swapon /dev/xvda1	[calls __frontswap_init, sets the need_init bitmap]
       modprobe tmem		[calls frontswap_register_ops, -->init calls, finds out
      			tmem_frontswap_poolid is 0, does not make a hypercall.
      			Later in the module_init, sets tmem_frontswap_poolid=-1]
      Which meant that in the failing case we would not call the hypercall
      to initialize the pool and never be able to make any frontswap
      backend calls.
      Moving the frontswap_register_ops after setting the tmem_frontswap_poolid
      fixes it.
