The hwmon core uses device managed functions, tied to the hwmon parent
device, for various internal memory allocations. This is problematic
since hwmon device lifetime does not necessarily match its parent's
device lifetime. If there is a mismatch, memory leaks will accumulate
until the parent device is released.
Fix the problem by managing all memory allocations internally. The only
exception is memory allocation for thermal device registration, which
can be tied to the hwmon device, along with thermal device registration
itself.

reg2volt returns the voltage that matches a given register value.
Converting this back the other way with volt2reg didn't return the same
register value because it used truncation instead of rounding.
This meant that values read from sysfs could not be written back to sysfs
to set back the same register value.
With this change, volt2reg will return the same value for every voltage
previously returned by reg2volt (for the set of possible input values)

No alarm is reported by /sys/.../inX_alarm
In detail:
The SMI Voltage status register is the only register giving a status
for voltages, but it does not work like the non-SMI status registers
used for temperatures and fans.
A bit is set for each input crossing a threshold, in both direction,
but the "inside" or "outside" limits info is not available.
Also this register is cleared on read.
Note : this is not explicitly spelled out in the datasheet, but from
experiment.
As a result if an input is crossing a threshold (min or max in any
direction), the alarm is reported only once even if the input is
still outside limits. Also if the alarm for another input is read
before the one of this input, no alarm is reported at all.

We now use btrfs_can_overcommit() to see if we can flip a block group
read only. Before this would fail because we weren't taking into
account the usable un-allocated space for allocating chunks. With my
patches we were allowed to do the balance, which is technically correct.
The test is trying to start balance on degraded mount. So now we're
trying to allocate a chunk and cannot because we want to allocate a
RAID1 chunk, but there's only 1 device that's available for usage. This
results in an ENOSPC.
But we shouldn't even be making it this far, we don't have enough
devices to restripe. The problem is we're using btrfs_num_devices(),
that also includes missing devices. That's not actually what we want, we
need to use rw_devices.
The chunk_mutex is not needed here, rw_devices changes only in device
add, remove or replace, all are excluded by EXCL_OP mechanism.

progress scrub has done if an error happened - this includes -ECANCELED
which is returned when users ask for scrub to stop. A particular use
case, which is used in btrfs-progs, is to resume scrub after it is
canceled, in that case it relies on checking the progress from the scrub
arguments structure and then use that progress in a call to resume
scrub.
So fix this by always copying the scrub arguments structure to user
space, overwriting the value returned to user space with -EFAULT only if
copying the structure failed to let user space know that either that
copying did not happen, and therefore the structure is stale, or it
happened partially and the structure is probably not valid and corrupt
due to the partial copy.

We would not be transmitting using the correct SYSTEMPORT transmit queue
during ndo_select_queue() which looks up the internal TX ring map
because while establishing the mapping we would be off by 4, so for
instance, when we populate switch port mappings we would be doing:
switch port 0, queue 0 -> ring index #0
switch port 0, queue 1 -> ring index #1
...
switch port 0, queue 3 -> ring index #3
switch port 1, queue 0 -> ring index #8 (4 + 4 * 1)
...
instead of using ring index #4. This would cause our ndo_select_queue()
to use the fallback queue mechanism which would pick up an incorrect
ring for that switch port. Fix this by using the correct switch queue
number instead of SYSTEMPORT queue number.

Vince reports a worrying issue:
| so I was tracking down some odd behavior in the perf_fuzzer which turns
| out to be because perf_even_open() sometimes returns 0 (indicating a file
| descriptor of 0) even though as far as I can tell stdin is still open.
... and further the cause:
| error is triggered if aux_sample_size has non-zero value.
|

|
| if (perf_need_aux_event(event) && !perf_get_aux_event(event, group_leader))
| goto err_locked;
|
| (note, err is never set)
This seems to be a thinko in commit:
ab43762ef0 ("perf: Allow normal events to output AUX data")

happen when the new event is mis-configured or does not have a
compatible aux_event group leader.

When there is not enough memory and napi_alloc_skb() return NULL,
the HNS driver will print error message, and than try again, if
the memory is not enough for a while, huge error message and the
retry operation will cause soft lockup.
When napi_alloc_skb() return NULL because of no memory, we can
get a warn_alloc() call trace, so this patch deletes the error
message. We already use polling mode to handle irq, but the
retry operation will render the polling weight inactive, this
patch just return budget when the rx is not completed to avoid
dead loop.

USB-serial drivers must not be unbound from their ports before the
corresponding USB driver is unbound from the parent interface so
suppress the bind and unbind attributes.
Unbinding a serial driver while it's port is open is a sure way to
trigger a crash as any driver state is released on unbind while port
hangup is handled on the parent USB interface level. Drivers for
multiport devices where ports share a resource such as an interrupt
endpoint also generally cannot handle individual ports going away.

syzbot reported some bogus lockdep warnings, for example bad unlock
balance in sch_direct_xmit(). They are due to a race condition between
slow path and fast path, that is qdisc_xmit_lock_key gets re-registered
in netdev_update_lockdep_key() on slow path, while we could still
acquire the queue->_xmit_lock on fast path in this small window:
CPU A CPU B
__netif_tx_lock();
lockdep_unregister_key(qdisc_xmit_lock_key);
__netif_tx_unlock();
lockdep_register_key(qdisc_xmit_lock_key);
In fact, unlike the addr_list_lock which has to be reordered when
the master/slave device relationship changes, queue->_xmit_lock is
only acquired on fast path and only when NETIF_F_LLTX is not set,
so there is likely no nested locking for it.
Therefore, we can just get rid of re-registration of
qdisc_xmit_lock_key.

writer to spin on the owner. Unfortunately, if the owner happens to be
RWSEM_OWNER_UNKNOWN, the code will incorrectly spin on it leading to a
kernel crash. This is fixed by passing the proper non-spinnable bits
to rwsem_spin_on_owner() so that RWSEM_OWNER_UNKNOWN will be treated
as a non-spinnable target.

The F54 Report Data is apparently read through a fifo and for
the smbus protocol that means that between reading a block of 32
bytes the rmiaddr shouldn't be incremented. However, changing
that causes other non-fifo reads to fail and so that change was
reverted.
This patch changes just the F54 function and it now reads 32 bytes
at a time from the fifo, using the F54_FIFO_OFFSET to update the
start address that is used when reading from the fifo.
This has only been tested with smbus, not with i2c or spi. But I
suspect that the same is needed there since I think similar
problems will occur there when reading more than 256 bytes.

I've been sitting on these longer than I meant, so the patch count is
a bit higher than ideal for this part of the release. There's also some
reverts of double-applied patches that brings the diffstat up a bit.

- Move of two device nodes that got applied to the wrong part of the
tree on ASpeed G6.
- Regulator fix for Beaglebone X15 (adding 12/5V supplies)
- Use interrupts for keys on Amlogic SM1 to avoid missed polls
In addition to that, there is a collection of smaller DT fixes:

Pull ARM SoC fixes from Olof Johansson:
"I've been sitting on these longer than I meant, so the patch count is
a bit higher than ideal for this part of the release. There's also
some reverts of double-applied patches that brings the diffstat up a
bit.
With that said, the biggest changes are:
- Revert of duplicate i2c device addition on two Aspeed (BMC)
Devicetrees.
- Move of two device nodes that got applied to the wrong part of the
tree on ASpeed G6.
- Regulator fix for Beaglebone X15 (adding 12/5V supplies)
- Use interrupts for keys on Amlogic SM1 to avoid missed polls
In addition to that, there is a collection of smaller DT fixes:
- Power supply assignment fixes for i.MX6
- Fix of interrupt line for magnetometer on i.MX8 Librem5 devkit
- Build fixlets (selects) for davinci/omap2+
- More interrupt number fixes for Stratix10, Amlogic SM1, etc.
- ... and more similar fixes across different platforms

- optee fix to register multiple shared pages properly

fix for PM on TI SoCs with sysc devices and fixes a bunch of clks that
are stuck always enabled on Qualcomm SDM845 SoCs. Allwinner SoCs get the
usual set of fixes too, mostly correcting drivers to have the right bits
that match the hardware. There's also a Samsung and Tegra fix in here
to mark a clk critical and avoid a double free. And finally there's a
fix for critical clks that silences a big warning splat about trying
to enable a clk that couldn't even be prepared.

Upon resuming from hibernation, free pages may contain stale data from
the kernel that initiated the resume. This breaks the invariant
inflicted by init_on_free=1 that freed pages must be zeroed.
To deal with this problem, make clear_free_pages() also clear the free
pages when init_on_free is enabled.

If the SME and SEV features are present via CPUID, but memory encryption
support is not enabled (MSR 0xC001_0010[23]), the feature flags are cleared
using clear_cpu_cap(). However, if get_cpu_cap() is later called, these
feature flags will be reset back to present, which is not desired.
Change from using clear_cpu_cap() to setup_clear_cpu_cap() so that the
clearing of the flags is maintained.
