      intel_idle: Allow ACPI _CST to be used for selected known processors · bff8e60a
      Rafael J. Wysocki authored
      Update the intel_idle driver to get the C-states information from ACPI
      _CST in some cases in which the processor is known to the driver, as long as
      that information is available and the new use_acpi flag is set in the
      profile of the processor in question.
      
      In the cases when there is a specific table of C-states for the given
      processor in the driver, that table is used as the primary source of
      information on the available C-states, but if ACPI _CST is present,
      the C-states that are not listed by it will not be enabled by default
      (they still can be enabled later by user space via sysfs, though).
      
      The new CPUIDLE_FLAG_ALWAYS_ENABLE flag can be used for marking
      C-states that should be enabled by default even if they are not
      listed by ACPI _CST.

      cpuidle: Allow idle states to be disabled by default · 75a80267
      Rafael J. Wysocki authored
      In certain situations it may be useful to prevent some idle states
      from being used by default while allowing user space to enable them
      later on.
      
      For this purpose, introduce a new state flag, CPUIDLE_FLAG_OFF, to
      mark idle states that should be disabled by default, make the core
      set CPUIDLE_STATE_DISABLED_BY_USER for those states at the
      initialization time and add a new state attribute in sysfs,
      "default_status", to inform user space of the initial status of
      the given idle state ("disabled" if CPUIDLE_FLAG_OFF is set for it,
      "enabled" otherwise).

      intel_idle: Use ACPI _CST for processor models without C-state tables · 18734958
      Rafael J. Wysocki authored
      Modify the intel_idle driver to get the C-states information from ACPI
      _CST if the processor model is not recognized by it.
      
      The processor is still required to support MWAIT and the information
      from ACPI _CST will only be used if all of the C-states listed by
      _CST are of the ACPI_CSTATE_FFH type (which means that they are
      expected to be entered via MWAIT).
      
      Moreover, the driver assumes that the _CST information is the same
      for all CPUs in the system, so it is sufficient to evaluate _CST for
      one of them and extract the common list of C-states from there.
      Also _CST is evaluated once at the system initialization time and
      the driver does not respond to _CST change notifications (that can
      be changed in the future).
      
      The main functional difference between intel_idle with this change
      and the ACPI processor driver is that the former sets the target
      residency to be equal to the exit latency (provided by _CST) for
      C1-type C-states and to 3 times the exit latency value for the other
      C-state types, whereas the latter obtains the target residency by
      multiplying the exit latency by the same number (2 by default) for
      all C-state types.  Therefore it is expected that in general using
      the former instead of the latter on the same system will lead to
      improved energy-efficiency.

      The intel_idle driver will be modified to use ACPI _CST subsequently

      function to acpi_processor.c so that it is always present (which is

        kernel-centric functions:
      
        For each replacement of ksys_mount() with do_mount(), one needs to
        verify that the first and third parameter (char *dev_name, char *type)
        are strings allocated in kernelspace and that the fifth parameter
        (void *data) is either NULL or refers to a full page (only occurence

        parameters (char *dir_name, unsigned long flags) are passed by
        ksys_mount() to do_mount() unchanged, and therefore do not require
        particular care.
      
        Moreover, instead of pretending to be userspace, the opening of

      xen/balloon: fix ballooned page accounting without hotplug enabled · c673ec61
      Juergen Gross authored
      When CONFIG_XEN_BALLOON_MEMORY_HOTPLUG is not defined
      reserve_additional_memory() will set balloon_stats.target_pages to a
      wrong value in case there are still some ballooned pages allocated via
      alloc_xenballooned_pages().
      
      This will result in balloon_process() no longer be triggered when
      ballooned pages are freed in batches.

      xen-blkback: prevent premature module unload · fa2ac657
      Paul Durrant authored
      Objects allocated by xen_blkif_alloc come from the 'blkif_cache' kmem
      cache. This cache is destoyed when xen-blkif is unloaded so it is
      necessary to wait for the deferred free routine used for such objects to
      complete. This necessity was missed in commit 14855954 "xen-blkback:
      allow module to be cleanly unloaded". This patch fixes the problem by
      taking/releasing extra module references in xen_blkif_alloc/free()
      respectively.
