The Jensen IO functions are overly copmplicated because some of the IO
addresses refer to special 'local IO' ports, and they get accessed
differently.
That then makes gcc not actually inline them, and since they were marked
"extern inline" when included through the regular <asm/io.h> path, and
then only marked "inline" when included from sys_jensen.c, you never
necessarily got a body for the IO functions at all.
The intent of the sys_jensen.c code is to actually get the non-inlined
copy generated, so remove the 'inline' from the magic macro that is
supposed to sort this all out.
Also, do not mix 'extern inline' functions (that may or may not be
inlined and will not generate a function body if they are not) with
'static inline' (that _will_ generate a function body when not inlined).
Because gcc will complain about this situation:
error: ‘jensen_bus_outb’ is static but used in inline function ‘jensen_outb’ which is not static
because gcc basically doesn't know whether to generate a body for that
static inline function or not for that call site.
So make all of these use that __EXTERN_INLINE marker. Gcc will
generally not inline these things on use, and then generate the function
body out-of-line in sys_jensen.c.
This makes the core IO functions build for the alpha Jensen config.
Not that the rest then builds, because it turns out Jensen also doesn't
enable PCI, which then makes other drievrs very unhappy, but that's a
separate issue.

Without CONFIG_PM enabled, the SET_RUNTIME_PM_OPS() macro ends up being

The separation of pinctrl and gpio drivers created a tiny window where
a pinconfig setting might produce a null-pointer dereference.
The affected device were rk3288-veyron devices in this case.
Pinctrl-hogs are claimed when the pinctrl driver is registered,
at which point their pinconfig settings will be applied.
At this time the now separate gpio devices will not have been created
yet and the matching driver won't have probed yet, making the gpio->foo()
call run into a null-ptr.
As probing is not really guaranteed to have been completed at a specific
time, introduce a queue that can hold the output settings until the gpio
driver has probed and will (in a separate patch) fetch the elements
of the list.
We expect the gpio driver to empty the list, but will nevertheless empty
it ourself on remove if that didn't happen.

It's not uncommon where __btrfs_dump_space_info() gets called
under over-commit situations.
In that case free space would underflow as total allocated space is not
enough to handle all the over-committed space.
Such underflow values can sometimes cause confusion for users enabled
enospc_debug mount option, and takes some seconds for developers to
convert the underflow value to signed result.
Just output the free space as s64 to avoid such problem.

When we get an error flushing one device, during a super block commit, we
record the error in the device structure, in the field 'last_flush_error'.
This is used to later check if we should error out the super block commit,
depending on whether the number of flush errors is greater than or equals
to the maximum tolerated device failures for a raid profile.
However if we get a transient device flush error, unmount the filesystem
and later try to mount it, we can fail the mount because we treat that
past error as critical and consider the device is missing. Even if it's
very likely that the error will happen again, as it's probably due to a
hardware related problem, there may be cases where the error might not
happen again. One example is during testing, and a test case like the
new generic/648 from fstests always triggers this. The test cases
generic/019 and generic/475 also trigger this scenario, but very
sporadically.
When this happens we get an error like this:
$ mount /dev/sdc /mnt
mount: /mnt wrong fs type, bad option, bad superblock on /dev/sdc, missing codepage or helper program, or other error.
$ dmesg
(...)
[12918.886926] BTRFS warning (device sdc): chunk 13631488 missing 1 devices, max tolerance is 0 for writable mount
[12918.888293] BTRFS warning (device sdc): writable mount is not allowed due to too many missing devices
[12918.890853] BTRFS error (device sdc): open_ctree failed
The failure happens because when btrfs_check_rw_degradable() is called at
mount time, or at remount from RO to RW time, is sees a non zero value in
a device's ->last_flush_error attribute, and therefore considers that the
device is 'missing'.
Fix this by setting a device's ->last_flush_error to zero when we close a
device, making sure the error is not seen on the next mount attempt. We
only need to track flush errors during the current mount, so that we never
commit a super block if such errors happened.

There is a BUG_ON() in btrfs_csum_one_bio() to catch code logic error.
It has indeed caught several bugs during subpage development.
But the BUG_ON() itself will bring down the whole system which is
an overkill.
Replace it with a WARN() and exit gracefully, so that it won't crash the
whole system while we can still catch the code logic error.

Pull io_uring iov_iter retry fixes from Jens Axboe:
"This adds a helper to save/restore iov_iter state, and modifies
io_uring to use it.
After that is done, we can now kill the iter->truncated addition that
we added for this release. The io_uring change is being overly
cautious with the save/restore/advance, but better safe than sorry and
we can always improve that and reduce the overhead if it proves to be
of concern. The only case to be worried about in this regard is huge
IO, where iteration can take a while to iterate segments.
I spent some time writing test cases, and expanded the coverage quite
a bit from the last posting of this. liburing carries this regression
test case now:
https://git.kernel.dk/cgit/liburing/tree/test/file-verify.c
which exercises all of this. It now also supports provided buffers,
and explicitly tests for end-of-file/device truncation as well.

The function __init_rwsem() is not part of the official API, it just a helper
function used by init_rwsem().
Changing the lock's class and name should be done by using
lockdep_set_class_and_name() after the has been fully initialized. The overhead
of the additional class struct and setting it twice is negligible and it works
across all locks.
Fully initialize the lock with init_rwsem() and then set the custom class and

pmic_gpio_child_to_parent_hwirq() and
gpiochip_populate_parent_fwspec_fourcell() translate a pinctrl-
spmi-gpio irqspec to an SPMI controller irqspec. When they do
this, they use a fixed SPMI slave ID of 0 and a fixed GPIO
peripheral offset of 0xC0 (corresponding to SPMI address 0xC000).
This translation results in an incorrect irqspec for secondary
PMICs that don't have a slave ID of 0 as well as for PMIC chips
which have GPIO peripherals located at a base address other than
0xC000.
Correct this issue by passing the slave ID of the pinctrl-spmi-
gpio device's parent in the SPMI controller irqspec and by
calculating the peripheral ID base from the device tree 'reg'
property of the pinctrl-spmi-gpio device.

from sysfs
Fan speed minimum can be enforced from sysfs. For example, setting
current fan speed to 20 is used to enforce fan speed to be at 100%
speed, 19 - to be not below 90% speed, etcetera. This feature provides
ability to limit fan speed according to some system wise
considerations, like absence of some replaceable units or high system
ambient temperature.
Request for changing fan minimum speed is configuration request and can
be set only through 'sysfs' write procedure. In this situation value of
argument 'state' is above nominal fan speed maximum.
Return non-zero code in this case to avoid
thermal_cooling_device_stats_update() call, because in this case
statistics update violates thermal statistics table range.
The issues is observed in case kernel is configured with option
CONFIG_THERMAL_STATISTICS.

tx timeout and slot time are currently specified in units of HZ. On
Alpha, HZ is defined as 1024. When building alpha:allmodconfig, this
results in the following error message.
drivers/net/hamradio/6pack.c: In function 'sixpack_open':
drivers/net/hamradio/6pack.c:71:41: error:
unsigned conversion from 'int' to 'unsigned char'
changes value from '256' to '0'
In the 6PACK protocol, tx timeout is specified in units of 10 ms and
transmitted over the wire:
https://www.linux-ax25.org/wiki/6PACK
Defining a value dependent on HZ doesn't really make sense, and
presumably comes from the (very historical) situation where HZ was
originally 100.
Note that the SIXP_SLOTTIME use explicitly is about 10ms granularity:
mod_timer(&sp->tx_t, jiffies + ((when + 1) * HZ) / 100);
and the SIXP_TXDELAY walue is sent as a byte over the wire.

[ Not so 'new' static annotations any more, and I removed the part of
the patch that added __maybe_unused to cdn_dp_suspend(), because it's
used by the shutdown/remove code.
