The card power state change via snd_power_change_state() at the system
suspend/resume seems dropped mistakenly during the PM code rewrite.
The card power state doesn't play much role nowadays but it's still
referred in a few places such as the HDMI codec driver.
This patch restores them, but in a more appropriate place now in the
prepare and complete callbacks.

A kernel panic was observed due to a timing issue between the sync thread
and the initiator processing a login response from the target. The session
reopen can be invoked both from the session sync thread when iscsid
restarts and from iscsid through the error handler. Before the initiator
receives the response to a login, another reopen request can be sent from
the error handler/sync session. When the initial login response is
subsequently processed, the connection has been closed and the socket has
been released.
To fix this a new connection state, ISCSI_CONN_BOUND, is added:
- Set the connection state value to ISCSI_CONN_DOWN upon
iscsi_if_ep_disconnect() and iscsi_if_stop_conn()
- Set the connection state to the newly created value ISCSI_CONN_BOUND
after bind connection (transport->bind_conn())
- In iscsi_set_param(), return -ENOTCONN if the connection state is not
either ISCSI_CONN_BOUND or ISCSI_CONN_UP

If a uaccess (e.g. get_user()) triggers a fault and there's a
fault signal pending, the handler will return to the uaccess without
having performed a uaccess fault fixup, and so the CPU will immediately
execute the uaccess instruction again, whereupon it will livelock
bouncing between that instruction and the fault handler.

pm_runtime_put_suppliers() must not decrement rpm_active unless the
consumer is suspended. That is because, otherwise, it could suspend
suppliers for an active consumer.
That can happen as follows:
static int driver_probe_device(struct device_driver *drv, struct device *dev)
{
int ret = 0;
if (!device_is_registered(dev))
return -ENODEV;
dev->can_match = true;
pr_debug("bus: '%s': %s: matched device %s with driver %s\n",
drv->bus->name, __func__, dev_name(dev), drv->name);
pm_runtime_get_suppliers(dev);
if (dev->parent)
pm_runtime_get_sync(dev->parent);
At this point, dev can runtime suspend so rpm_put_suppliers() can run,
rpm_active becomes 1 (the lowest value).
pm_runtime_barrier(dev);
if (initcall_debug)
ret = really_probe_debug(dev, drv);
else
ret = really_probe(dev, drv);
Probe callback can have runtime resumed dev, and then runtime put
so dev is awaiting autosuspend, but rpm_active is 2.
pm_request_idle(dev);
if (dev->parent)
pm_runtime_put(dev->parent);
pm_runtime_put_suppliers(dev);
Now pm_runtime_put_suppliers() will put the supplier
i.e. rpm_active 2 -> 1, but consumer can still be active.
return ret;
}
Fix by checking the runtime status. For any status other than
RPM_SUSPENDED, rpm_active can be considered to be "owned" by
rpm_[get/put]_suppliers() and pm_runtime_put_suppliers() need do nothing.

ACPI tables mapped via kmap() do not have their mapped pages
reserved and the pages can be "stolen" by the buddy allocator.
Apparently, on the affected system, the ACPI table in question is
not located in "reserved" memory, like ACPI NVS or ACPI Data, that
will not be used by the buddy allocator, so the memory occupied by
that table has to be explicitly reserved to prevent the buddy
allocator from using it.
In order to address this problem, rearrange the initialization of the
ACPI tables on x86 to locate the initial tables earlier and reserve
the memory occupied by them.
The other architectures using ACPI should not be affected by this
change.

- Use thread info versions of flag testing, as discussed last week.
- The series enabling PF_IO_WORKER to just take signals, instead of
needing to special case that they do not in a bunch of places. Ends
up being pretty trivial to do, and then we can revert all the special
casing we're currently doing.

As tasks always wait and kill their io-wq on exec/exit, files are of no
more concern to us, so we don't need to specifically cancel them by hand
in those cases. Moreover we should not, because io_match_task() looks at
req->task->files now, which is always true and so leads to extra
cancellations, that wasn't a case before per-task io-wq.

This is racy - move the blocking into when the task is created and
we're marking it as PF_IO_WORKER anyway. The IO threads are now
prepared to handle signals like SIGSTOP as well, so clear that from
the mask to allow proper stopping of IO threads.

We go through various hoops to disallow signals for the IO threads, but
there's really no reason why we cannot just allow them. The IO threads
never return to userspace like a normal thread, and hence don't go through
normal signal processing. Instead, just check for a pending signal as part
of the work loop, and call get_signal() to handle it for us if anything
is pending.
With that, we can support receiving signals, including special ones like
SIGSTOP.

Commit a33df75c63 ("block: use an xarray for disk->part_tbl") drops the
check on max supported number of partitionsr, and allows partition with
bigger partition numbers to be added. However, ->bd_partno is defined as
u8, so partition index of xarray table may not match with ->bd_partno.
Then delete_partition() may delete one unmatched partition, and caused

firmware: stratix10-svc: reset COMMAND_RECONFIG_FLAG_PARTIAL to 0
There were two problems (one of which could cause data corruption)
that were noticed with duplicate extents (ie reflink)
when debugging why various xfstests were being incorrectly skipped
(e.g. generic/138, generic/140, generic/142). First, we were not
updating the file size locally in the cache when extending a
file due to reflink (it would refresh after actimeo expires)
but xfstest was checking the size immediately which was still
0 so caused the test to be skipped. Second, we were setting
the target file size (which could shrink the file) in all cases
to the end of the reflinked range rather than only setting the
target file size when reflink would extend the file.

Make SMB2 not print out an error when an oplock break is received for an

these unknown handles may also be misleading, so fix that too.

Under SMB1 + POSIX, if an inode is reused on a server after we have read and
cached a part of a file, when we then open the new file with the
re-cycled inode there is a chance that we may serve the old data out of cache
to the application.
This only happens for SMB1 (deprecated) and when posix are used.
The simplest solution to avoid this race is to force a revalidate
on smb1-posix open.

in preparation for doing so, don't handle a fatal signal for them. The

instead of calling do_exit() on their behalf. The threads themselves will
detect a fatal signal and do proper shutdown.

Pull power management fixes from Rafael Wysocki:
"These fix an issue related to device links in the runtime PM framework
and debugfs usage in the Energy Model code.
Specifics:
- Modify the runtime PM device suspend to avoid suspending supplier
devices before the consumer device's status changes to
RPM_SUSPENDED (Rafael Wysocki)
- Change the Energy Model code to prevent it from attempting to
create its main debugfs directory too early (Lukasz Luba)"
* tag 'pm-5.12-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
PM: EM: postpone creating the debugfs dir till fs_initcall
PM: runtime: Defer suspending suppliers
Too many fixes have accumulated in the soc tree, so this is a fairly
large set. As usual, most of the fixes are for devicetree files, but
there are also notable code changes for imx and omap regressions as
well as some maintainer file updates.
imx:
- Fix an Ethernet issue on imx6ul-14x14-evk board that is caused by
independent PHY reset.
- Add missing `dma-coherent` property for LayerScape device trees to fix a
kernel BUG report.
- Use IRQCHIP_DECLARE for AVIC driver to fix a boot issue on i.MX25 with
fw_devlink=on.
- Add missing I2C pinctrl entry for imx8mp-phyboard-pollux-rdk board to
fix the broken I2C GPIO recovery support.
- Add `fsl,use-minimum-ecc` property for imx6ull-myir-mys-6ulx-eval
device tree to fix UBI filesystem mount failure.
at91:
- wrong phy address that blocks Ethernet use on boards with sama5d27 SoM1
- restrictive pin possibilities for sam9x60
omap:
- Fix ocp interconnect bus access error reporting for omap_l3_noc by
setting IRQF_NO_THREAD
- Fix changed mmc slot order regression by adding mmc aliases for am335x
- Fix dra7 reboot regression caused by invalid pcie reset map
- Fix smartreflex init regression caused by dropped legacy data
- Fix ti-sysc driver warning on unbind if reset is not deasserted
- Fix flakey reset deassert for dra7 iva
