      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
      f96972f2
      
       ("kernel/sys.c: call disable_nonboot_cpus() in
      kernel_restart()").
      
      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
      that.
      
      Restructure the code and make it generic enough to be useful for other
      usecases too.

      EE is hard-disabled on entry to kvmppc_handle_exit(), so call
      hard_irq_disable() so that PACA_IRQ_HARD_DIS is set, and soft_enabled
      is unset.
      
      Without this, we get warnings such as arch/powerpc/kernel/time.c:300,
      and sometimes host kernel hangs.

      The previous patch made 64-bit booke KVM build again, but Altivec
      support is still not complete, and we can't prevent the guest from
      turning on Altivec (which can corrupt host state until state
      save/restore is implemented).  Disable e6500 on KVM until this is
      fixed.

      IVORs 32 and 33 are shared so reflect this in the interrupts naming.

      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.
      
      Thanks to Tejun Heo and Rusty Russell and others for helping me track
      this down.
      
      This was introduced in 3.9 by commit c10d7367
      
       ("softirq: reduce
      latencies").
      
      It may be worth looking into ath9k to see if it has issues with its irq
      handler at a later date.
      
      The hang stack traces look something like this:

      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.

       - Trivial: unused variable removal
      
       - Posix-timers: Add the clock ID to the new proc interface to make it
         useful.  The interface is new and should be functional when we reach
         the final 3.10 release.
      
       - Cure a false positive warning in the tick code introduced by the
         overhaul in 3.10
      
       - Fix for a persistent clock detection regression introduced in this
         cycle

      irqchip: Return -EPERM for reserved IRQs · d94ea3f6
      Grant Likely authored
      
      
      The irqdomain core will report a log message for any attempted map call
      that fails unless the error code is -EPERM. This patch changes the
      Versatile irq controller drivers to use -EPERM because it is normal for
      a subset of the IRQ inputs to be marked as reserved on the various
      Versatile platforms.

      irqdomain: document the simple domain first_irq · 94a63da0
      Linus Walleij authored
      
      
      The first_irq needs to be zero to get a linear domain and that
      comes with special semantics. We want to simplify this going
      forward but some documentation never hurts.

      Since irq_data may be NULL, if so, we WARN_ON(), and continue, 'hwirq'
      which related with 'irq_data' has to initialize later, or it will cause
      issue.

      All other irq_domain_add_* functions are exported already, and apparently
      this one got left out by mistake, which causes build errors for ARM
      allmodconfig kernels:
