User space uses this field to count physical DAIs, not only BE DAIs since
users may not use DPCM. So we rename this field from be_dai_elems to
dai_elems.
This change is backward compatible, because it does not change the layout
of the struct or data type.

Add a new flag bit SND_SOC_TPLG_LNK_FLGBIT_VOICE_WAKEUP to link flags.

Code refactoring. These functions and variables are for configuring

Rename the ABI struct and type because they are for configuring physical
DAIs, not only backend DAIs since users may not need DPCM:
- Rename struct snd_soc_tplg_be_dai to snd_soc_tplg_dai.
- Rename type SND_SOC_TPLG_TYPE_BE_DAI to SND_SOC_TPLG_TYPE_DAI.
This code refactoring is backward compatible because:
- Both layout of the struct and type value has no change. Kernel can
find the same type value and map to same data layout.
- This struct is not in ABI v4 at all. Now the user space uses ABI v4.

Topology will find an existing physical link (including BE link for

Define the API to find an existing DAI link of the soc card by matching
the ID, name and stream name.
Some cards may use unique ID for each DAI link, so matching ID is enough,
and name or stream name are not necessary. But user need to specify name
or stream name as well if not sure whether link ID is unique since most
cards use 0 as the default link ID.
Topology can use this API to find an existing BE link and configure it.

The following fields are added to physical link configuration struct
(snd_soc_tplg_link_config) in ABI v5:
- name and stream name
Topology will use them to find an existing physical link and configure
it.
- HW configurations
Define the types and ABI struct for runtime supported hardware configs
of physical DAI links, e.g. audio hardware formats. The default HW
config ID will help topology to find the DAI format to set on init.
Topology provides this as a fallback if such HW settings are not
available in ACPI or device tree, to avoid hard code in drivers. It's
only for config items that can be programmed by SW or FW, not for
physical things like link connections or GPIO used for HP etc.
- flags and private data
The flags will be used to configure an existing physical DAI link.
The private data is reserved for future extension.
NOTE: Current kernel has no support for physical links. A later patch
will add support for configuring physical links and make the support
backward compatible for ABI v4.

This is the remaining update to PCM ABI object of version 5.

This patch adds support for old version 4 of PCMs (FE DAI & DAI links).
Topology ABI v5 added new fields to stream caps and thus changed PCMs.
Since user space may still uses v4, kernel will check the ABI version by
comparing the object size. If user space uses v4 of PCMs, kernel will
create the latest version of PCMs from the old version, and use the new
version internally to create FE DAI & DAI links. Because these new created
PCM elements will be freed later, kernel need duplicate the name strings
of DAI driver and DAI links when creating them.

Change thaw_super() to check frozen != SB_FREEZE_COMPLETE rather than
frozen == SB_UNFROZEN, otherwise it can race with freeze_super() which
drops sb->s_umount after SB_FREEZE_WRITE to preserve the lock ordering.
In this case thaw_super() will wrongly call s_op->unfreeze_fs() before
it was actually frozen, and call sb_freeze_unlock() which leads to the

Both import_iovec() and rw_copy_check_uvector() take an array
(typically small and on-stack) which is used to hold an iovec array copy
from userspace. This is to avoid an expensive memory allocation in the
fast path (i.e. few iovec elements).
The caller may have to check whether these functions actually used
the provided buffer or allocated a new one -- but this differs between
the too. Let's just add a kernel doc to clarify what the semantics are
for each function.

Pull rdma qedr RoCE driver from Doug Ledford:
"Early on in the merge window I mentioned I had a backlog of new
drivers waiting to be reviewed and that, in addition to the hns-roce
driver, I wanted to get possible a couple more reviewed. I ended up
only having the time to complete one of the additional drivers.
During Dave Miller's pull request this go around, there were a series
of 9 patches to the QLogic qed net driver that add basic support for a
paired RoCE driver. That support is currently not functional because
it is missing the matching RoCE driver in the RDMA subsystem. I
managed to finish that review. However, because it goes against part
of Dave's net pull, and a part that was accepted a day or two after
the merge window opened, to apply cleanly it has to be applied to
either the tip of Dave's net branch, or as I did in this case, I just
applied it to your master after you had taken Dave's pull request."

Merge tag 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull more rdma updates from Doug Ledford:
"This merge window was the first where Huawei had to try and coordinate
their patches between their net driver and their new roce driver
(similar to mlx4 and mlx5).
They didn't do horribly, but there were some issues (and we knew that
because they simply didn't know what to do in the beginning). As a
result, I had a set of patches that depended on some patches that
normally would have come to you via Dave's tree. Those patches have
been on netdev@ for a while, so I got Dave to give me his approval to
send them to you. As such, the other 29 patches I had behind them are
also now ready to go.
This catches the hns and hns-roce drivers up to current, and for
future patches we are working with them to get them up to speed on how
to do joint driver development so that they don't have these sorts of
cross tree dependency issues again. BTW, Dave gave me permission to
add his Acked-by: to the patches against the net tree, but I've had
this branch through 0day (but not linux-next since it was off by
itself) and I didn't want to rebase the series just to add Dave's ack
for the 8 patches in the net area.

- Various fixes to the hns-roce driver

Pull more power management updates from Rafael Wysocki:
"This includes a couple of fixes for cpufreq regressions introduced in
4.8, a rework of the intel_pstate algorithm used on Atom processors
(that took some time to test) plus a fix and a couple of cleanups in
that driver, a CPPC cpufreq driver fix, and a some devfreq fixes and
cleanups (core and exynos-nocp).
Specifics:
- Fix two cpufreq regressions causing undesirable changes in behavior
to appear (one in the core and one in the conservative governor)
introduced during the 4.8 cycle (Aaro Koskinen, Rafael Wysocki).
- Fix the way the intel_pstate driver accesses MSRs related to the
hardware-managed P-states (HWP) feature during the initialization
which currently is unsafe and may cause the processor to generate a
general protection fault (Srinivas Pandruvada).
- Rework the intel_pstate's P-state selection algorithm used on Atom
processors to avoid known problems with the current one and to make
the computation more straightforward, which also happens to improve
performance in multiple benchmarks a bit (Rafael Wysocki).
- Improve two comments in the intel_pstate driver (Rafael Wysocki).
- Fix the desired performance computation in the CPPC cpufreq driver
(Hoan Tran).
- Fix the devfreq core to avoid printing misleading error messages in
some cases (Tobias Jakobi).
- Fix the error code path in devfreq_add_device() to use proper
locking around list modifications (Axel Lin).
- Fix a build failure and remove a couple of redundant updates of
variables in the exynos-nocp devfreq driver (Axel Lin)"

New mount option "idsfromsid" indicates to cifs.ko that
it should try to retrieve the uid and gid owner fields
from special sids. This patch adds the code to parse the owner
sids in the ACL to see if they match, and if so populate the
uid and/or gid from them. This is faster than upcalling for
them and asking winbind, and is a fairly common case, and is
also helpful when cifs.upcall and idmapping is not configured.

Add "idsfromsid" mount option to indicate to cifs.ko that it should
try to retrieve the uid and gid owner fields from special sids in the
ACL if present. This first patch just adds the parsing for the mount
option.
