regulator: da9063: Fix get_mode() functions to read sleep field
get_mode() is used to retrieve the active mode state. Settings-A
config is used during active state, whilst Settings-B is for
suspend. This means we only need to check the sleep field of each
buck and LDO as that field solely relates to Settings-A config.

13c5a577b3 drm/i915/gt: Select the deepest available parking mode for rc6
On Ivybridge, we can go lower than rc6 to rc6p. And this is required for
Ivybridge to hit the same minimum power consumption as rc6 on other
platforms, so make it so.

v2: Update selftest to include all rc6 residency counters

Note that Andi did mention that we should be converting the magic
numbers into opaque magic macros, so if they ever get reused (unlikely
given only Ivybridge used the extra modes) we'll need to pay back the
technical debt.

93de44eb3f dm writecache: implement the "cleaner" policy
The "flush" or "flush_on_suspend" messages flush the whole cache. However,
these flushing methods can take some time and the process is left in
an interruptible state during the flush.

Implement a "cleaner" option that offers an alternate flushing method.
When this option is activated (either by a message or in the constructor
arguments), the cache will not promote new writes (however, writes to
already cached blocks are promoted, to avoid data corruption due to
misordered writes) and it will gradually writeback any cached data. The
userspace can then monitor the cleaning process with "dmsetup status".
When the number of cached bloks drops to zero, the userspace can unload
the dm-writecache target and replace it with dm-linear or other targets.

137e553135 vfio/pci: Add sriov_configure support
With the VF Token interface we can now expect that a vfio userspace
driver must be in collaboration with the PF driver, an unwitting
userspace driver will not be able to get past the GET_DEVICE_FD step
in accessing the device.  We can now move on to actually allowing
SR-IOV to be enabled by vfio-pci on the PF.  Support for this is not
enabled by default in this commit, but it does provide a module option
for this to be enabled (enable_sriov=1).  Enabling VFs is rather
straightforward, except we don't want to risk that a VF might get
autoprobed and bound to other drivers, so a bus notifier is used to
"capture" VFs to vfio-pci using the driver_override support.  We
assume any later action to bind the device to other drivers is
condoned by the system admin and allow it with a log warning.

vfio-pci will disable SR-IOV on a PF before releasing the device,
allowing a VF driver to be assured other drivers cannot take over the
PF and that any other userspace driver must know the shared VF token.
This support also does not provide a mechanism for the PF userspace
driver itself to manipulate SR-IOV through the vfio API.  With this
patch SR-IOV can only be enabled via the host sysfs interface and the
PF driver user cannot create or remove VFs.

43eeeecc8e vfio: Introduce VFIO_DEVICE_FEATURE ioctl and first user
The VFIO_DEVICE_FEATURE ioctl is meant to be a general purpose, device
agnostic ioctl for setting, retrieving, and probing device features.
This implementation provides a 16-bit field for specifying a feature
index, where the data porition of the ioctl is determined by the
semantics for the given feature.  Additional flag bits indicate the
direction and nature of the operation; SET indicates user data is
provided into the device feature, GET indicates the device feature is
written out into user data.  The PROBE flag augments determining
whether the given feature is supported, and if provided, whether the
given operation on the feature is supported.

The first user of this ioctl is for setting the vfio-pci VF token,
where the user provides a shared secret key (UUID) on a SR-IOV PF
device, which users must provide when opening associated VF devices.

cc20d79990 vfio/pci: Introduce VF token
If we enable SR-IOV on a vfio-pci owned PF, the resulting VFs are not
fully isolated from the PF.  The PF can always cause a denial of service
to the VF, even if by simply resetting itself.  The degree to which a PF
can access the data passed through a VF or interfere with its operation
is dependent on a given SR-IOV implementation.  Therefore we want to
avoid a scenario where an existing vfio-pci based userspace driver might
assume the PF driver is trusted, for example assigning a PF to one VM
and VF to another with some expectation of isolation.  IOMMU grouping
could be a solution to this, but imposes an unnecessarily strong
relationship between PF and VF drivers if they need to operate with the
same IOMMU context.  Instead we introduce a "VF token", which is
essentially just a shared secret between PF and VF drivers, implemented
as a UUID.

The VF token can be set by a vfio-pci based PF driver and must be known
by the vfio-pci based VF driver in order to gain access to the device.
This allows the degree to which this VF token is considered secret to be
determined by the applications and environment.  For example a VM might
generate a random UUID known only internally to the hypervisor while a
userspace networking appliance might use a shared, or even well know,
UUID among the application drivers.

To incorporate this VF token, the VFIO_GROUP_GET_DEVICE_FD interface is
extended to accept key=value pairs in addition to the device name.  This
allows us to most easily deny user access to the device without risk
that existing userspace drivers assume region offsets, IRQs, and other
device features, leading to more elaborate error paths.  The format of
these options are expected to take the form:

"$DEVICE_NAME $OPTION1=$VALUE1 $OPTION2=$VALUE2"

Where the device name is always provided first for compatibility and
additional options are specified in a space separated list.  The
relation between and requirements for the additional options will be
vfio bus driver dependent, however unknown or unused option within this
schema should return error.  This allow for future use of unknown
options as well as a positive indication to the user that an option is
used.

An example VF token option would take this form:

"0000:03:00.0 vf_token=2ab74924-c335-45f4-9b16-8569e5b08258"

When accessing a VF where the PF is making use of vfio-pci, the user
MUST provide the current vf_token.  When accessing a PF, the user MUST
provide the current vf_token IF there are active VF users or MAY provide
a vf_token in order to set the current VF token when no VF users are
active.  The former requirement assures VF users that an unassociated
driver cannot usurp the PF device.  These semantics also imply that a
VF token MUST be set by a PF driver before VF drivers can access their
device, the default token is random and mechanisms to read the token are
not provided in order to protect the VF token of previous users.  Use of
the vf_token option outside of these cases will return an error, as
discussed above.

40280cf7e8 vfio: avoid inefficient operations on VFIO group in vfio_pin/unpin_pages
vfio_group_pin_pages() and vfio_group_unpin_pages() are introduced to
avoid inefficient search/check/ref/deref opertions associated with VFIO
group as those in each calling into vfio_pin_pages() and
vfio_unpin_pages().

VFIO group is taken as arg directly. The callers combine
search/check/ref/deref operations associated with VFIO group by calling
vfio_group_get_external_user()/vfio_group_get_external_user_from_dev()
beforehand, and vfio_group_put_external_user() afterwards.

c0560f51cf vfio: allow external user to get vfio group from device
external user calls vfio_group_get_external_user_from_dev() with a device
pointer to get the VFIO group associated with this device.
The VFIO group is checked to be vialbe and have IOMMU set. Then
container user counter is increased and VFIO group reference is hold
to prevent the VFIO group from disposal before external user exits.

when the external user finishes using of the VFIO group, it calls
vfio_group_put_external_user() to dereference the VFIO group and the
container user counter.

723fe298ad vfio: platform: Switch to platform_get_irq_optional()
Since commit 7723f4c5ec ("driver core: platform: Add an error
message to platform_get_irq*()"), platform_get_irq() calls dev_err()
on an error. As we enumerate all interrupts until platform_get_irq()
fails, we now systematically get a message such as:
"vfio-platform fff51000.ethernet: IRQ index 3 not found" which is
a false positive.

Let's use platform_get_irq_optional() instead.

0d33b34352 perf dso: Fix dso comparison
Perf gets dso details from two different sources. 1st, from builid
headers in perf.data and 2nd from MMAP2 samples. Dso from buildid
header does not have dso_id detail. And dso from MMAP2 samples does
not have buildid information. If detail of the same dso is present
at both the places, filename is common.

Previously, __dsos__findnew_link_by_longname_id() used to compare only
long or short names, but Commit 0e3149f86b ("perf dso: Move dso_id
from 'struct map' to 'struct dso'") also added a dso_id comparison.
Because of that, now perf is creating two different dso objects of the
same file, one from buildid header (with dso_id but without buildid)
and second from MMAP2 sample (with buildid but without dso_id).

This is causing issues with archive, buildid-list etc subcommands. Fix
this by comparing dso_id only when it's present. And incase dso is
present in 'dsos' list without dso_id, inject dso_id detail as well.

Before:

  $ sudo ./perf buildid-list -H
  0000000000000000000000000000000000000000 /usr/bin/ls
  0000000000000000000000000000000000000000 /usr/lib64/ld-2.30.so
  0000000000000000000000000000000000000000 /usr/lib64/libc-2.30.so

  $ ./perf archive
  perf archive: no build-ids found

After:

  $ ./perf buildid-list -H
  b6b1291d0cead046ed0fa5734037fa87a579adee /usr/bin/ls
  641f0c90cfa15779352f12c0ec3c7a2b2b6f41e8 /usr/lib64/ld-2.30.so
  675ace3ca07a0b863df01f461a7b0984c65c8b37 /usr/lib64/libc-2.30.so

  $ ./perf archive
  Now please run:

  $ tar xvf perf.data.tar.bz2 -C ~/.debug

  wherever you need to run 'perf report' on.

Committer notes:

Renamed is_empty_dso_id() to dso_id__empty() and inject_dso_id() to
dso__inject_id() to keep namespacing consistent.

The enum containing the *_PARTITION symbolic names is only relevant

partition table system indicators and thus should go straight into
msdos.c.  One value is only used by the sun partition parser, and the
sun and sgi partition parsers use the same value as the x86 Linux
RAID indicator to also indicate RAID autodetection.  Duplicate them
in sun.c and sgi.c given that the different partition types use
entirely different values otherwise.
