This debug code dereferences "old_iface" after it was already freed by
the call to release_iface(). Re-order the debugging to avoid this
issue.

decrease file_map_count for a non-leaf pmd comes from collapse_huge_page().

When we post a CQE we wake all ring pollers as it normally should be.
However, if a CQE was generated by a multishot poll request targeting
its own ring, it'll wake that request up, which will make it to post
a new CQE, which will wake the request and so on until it exhausts all
CQ entries.
Don't allow multishot polling io_uring files but downgrade them to
oneshots, which was always stated as a correct behaviour that the
userspace should check for.

There was a problem that a user burned a dm-integrity image on CDROM
and could not activate it because it had a non-empty journal.
Fix this problem by flushing the journal (done by the previous commit)
and clearing the journal (done by this commit). Once the journal is
cleared, dm-integrity won't attempt to replay it on the next
activation.

This commit flushes the journal on suspend. It is prerequisite for the
next commit that enables activating dm integrity devices in read-only mode.
Note that we deliberately didn't flush the journal on suspend, so that the
journal replay code would be tested. However, the dm-integrity code is 5
years old now, so that journal replay is well-tested, and we can make this
change now.

__list_versions will first estimate the required space using the
"dm_target_iterate(list_version_get_needed, &needed)" call and then will
fill the space using the "dm_target_iterate(list_version_get_info,
&iter_info)" call. Each of these calls locks the targets using the
"down_read(&_lock)" and "up_read(&_lock)" calls, however between the first
and second "dm_target_iterate" there is no lock held and the target
modules can be loaded at this point, so the second "dm_target_iterate"
call may need more space than what was the first "dm_target_iterate"
returned.
The code tries to handle this overflow (see the beginning of
list_version_get_info), however this handling is incorrect.
The code sets "param->data_size = param->data_start + needed" and
"iter_info.end = (char *)vers+len" - "needed" is the size returned by the
first dm_target_iterate call; "len" is the size of the buffer allocated by
userspace.
"len" may be greater than "needed"; in this case, the code will write up
to "len" bytes into the buffer, however param->data_size is set to
"needed", so it may write data past the param->data_size value. The ioctl
interface copies only up to param->data_size into userspace, thus part of
the result will be truncated.
Fix this bug by setting "iter_info.end = (char *)vers + needed;" - this
guarantees that the second "dm_target_iterate" call will write only up to
the "needed" buffer and it will exit with "DM_BUFFER_FULL_FLAG" if it
overflows the "needed" space - in this case, userspace will allocate a
larger buffer and retry.
Note that there is also a bug in list_version_get_needed - we need to add
"strlen(tt->name) + 1" to the needed size, not "strlen(tt->name)".

Since commit c7e3ca515e78 ("iommu/tegra: gart: Do not register with
bus") quite some time ago, the GART driver has effectively disabled
itself to avoid issues with the GPU driver expecting it to work in ways
that it doesn't. As of commit 57365a04c921 ("iommu: Move bus setup to
IOMMU device registration") that bodge no longer works, but really the
GPU driver should be responsible for its own behaviour anyway. Make the
workaround explicit.

"Another set of devicetree and code changes for SoC platforms, notably:
- DT schema warning fixes for i.MX
- Functional fixes for i.MX tqma8mqml-mba8mx USB and i.MX8M OCOTP
- MAINTAINERS updates for Hisilicon and RISC-V, documenting which
RISC-V SoC specific patches will now get merged through the SoC
tree in the future.
- A code fix for at91 suspend, to work around broken hardware
- A devicetree fix for lan966x/pcb8291 LED support
- Lots of DT fixes for Qualcomm SoCs, mostly fixing minor problems
like incorrect register sizes and schema warnings. One fix makes
the UFS controller work on sc8280xp, and six fixes address the same
regulator problem in a variety of platforms"

Having REQ_F_POLLED set doesn't guarantee that the request is
executed as a multishot from the polling path. Fortunately for us, if
the code thinks it's multishot issue when it's not, it can only ask to
skip completion so leaking the request. Use issue_flags to mark
multipoll issues.

When io_poll_check_events() collides with someone attempting to queue a
task work, it'll spin for one more time. However, it'll continue to use
the mask from the first iteration instead of updating it. For example,
if the first wake up was a EPOLLIN and the second EPOLLOUT, the
userspace will not get EPOLLOUT in time.
Clear the mask for all subsequent iterations to force vfs_poll().

An external PHY needs settling time after power up or reset.
In the bind() function an mdio bus is registered. If at this point
the external PHY is still initialising, no valid PHY ID will be
read and on phy_find_first() the bind() function will fail.
If an external PHY is present, wait the maximum time specified
in 802.3 45.2.7.1.1.
