With a 64-bit resource_size_t, we get a build warning on bcm63xx_spi_probe:
drivers/spi/spi-bcm63xx.c:565:16: warning: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'resource_size_t {aka long long unsigned int}' [-Wformat=]
As we are printing a resource, we can just use the %pr format
specifier that pretty-prints the address and avoids the warning.

We can now select clocksource drivers like ti-32k and CONFIG_OF
on ancient machines that still use gettimeoffset, and the combination
results in a link error.
arch/arm/kernel/built-in.o: In function `time_init':
(.init.text+0xc28): undefined reference to `clocksource_probe'
The reason for this is that the Makefile is hidden behind
CONFIG_ARCH_USES_GETTIMEOFFSET, but the Kconfig file is not, and
it has shown up just now because the ti-32k driver was added
and can be selected using COMPILE_TEST on all platforms.
This patch hides the Kconfig menu in CONFIG_ARCH_USES_GETTIMEOFFSET
as well.

The ftm_clockevent_init passes the value of "~0UL" into a function
that takes a 32-bit argument, which drops the upper 32 bits, as
gcc warns about on ARM64:
clocksource/fsl_ftm_timer.c: In function 'ftm_clockevent_init':
clocksource/fsl_ftm_timer.c:206:13: warning: large integer implicitly truncated to unsigned type [-Woverflow]
This was obviously unintended behavior, and is easily avoided by
using '~0u' as the integer literal, because that is 32-bit wide
on all architectures.

Currently it's assumed that firmware exports only the class of sensors
supported by the driver. However with newer firmware or SCPI protocol
revision, support for newer classes of sensors can be present.
The driver fails to probe with the following warning if an unsupported
class of sensor is encountered in the firmware.
sysfs: cannot create duplicate filename

The newly added scpi thermal support is broken when the scpi driver
is built-in but the thermal driver is a loadable module:
drivers/built-in.o: In function `scpi_hwmon_probe':
(.text+0x444d70): undefined reference to `thermal_zone_of_sensor_unregister'
(.text+0x444d94): undefined reference to `thermal_zone_of_sensor_register'
drivers/built-in.o: In function `scpi_hwmon_remove':
(text+0x444e6c): undefined reference to `thermal_zone_of_sensor_unregister'
This uses the same Kconfig trick that we have in a couple of other
drivers already to ensure we can only select the driver in valid
configurations when either THERMAL_OF is disabled, or when with a
dependency on CONFIG_THERMAL that can force SCPI to be a loadable
module in the case I was hitting.

The DEVICE_HWI type was added under the faulty assumption that Huawei
devices based on Qualcomm chipsets and firmware use the static USB
interface numbering known from Gobi devices. But this model does
not apply to Huawei devices like the HP branded lt4112 (Huawei me906e).
Huawei firmwares will dynamically assign interface numbers. Functions
are renumbered when the firmware is reconfigured.
Fix by changing the DEVICE_HWI type to use a simplified version
of Huawei's subclass + protocol scheme: Blacklisting known network
interface combinations and assuming the rest are serial.

There is a bit of a mess in the order of arguments to the ulpi write
callback. There is
int ulpi_write(struct ulpi *ulpi, u8 addr, u8 val)
in drivers/usb/common/ulpi.c;
struct usb_phy_io_ops {
...
int (*write)(struct usb_phy *x, u32 val, u32 reg);
}
in include/linux/usb/phy.h.
The callback registered by the musb driver has to comply to the latter,
but up to now had "offset" first which effectively made the function
broken for correct users. So flip the order and while at it also
switch to the parameter names of struct usb_phy_io_ops's write.

Before this patch the scheduler fence was created when we push the job
into the queue, so we could only get the fence after pushing it.
The mutex now was necessary to prevent the thread pushing the jobs to
the hardware from running faster than the thread pushing the jobs into
the queue.
Otherwise the thread pushing jobs into the queue would have accessed
possible freed up memory when it tries to get a reference to the fence.
So what you get in the end is thread A:
mutex_lock(&job->lock);
...
Kick of thread B.
...
mutex_unlock(&job->lock);
And thread B:
mutex_lock(&job->lock);
....
mutex_unlock(&job->lock);
kfree(job);
I'm actually not sure if I'm still up to date on this, but this usage
pattern used to be not allowed with mutexes. See here as well

The amdgpu driver has a debugfs interface that shows the amount of

drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c:1076:17: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'long long int' [-Wformat=]
This fixes the format string to use "%llu" for printing 64-bit
numbers, which works everywhere, as long as we also cast to 'u64'.
Unlike atomic64_t, u64 is defined as 'unsigned long long' on
all architectures.

transition
A thin-pool that is in out-of-data-space (OODS) mode may transition back
to write mode -- without the admin adding more space to the thin-pool --
if/when blocks are released (either by deleting thin devices or
discarding provisioned blocks).
But as part of the thin-pool's earlier transition to out-of-data-space
mode the thin-pool may have set the 'error_if_no_space' flag to true if
the no_space_timeout expires without more space having been made
available. That implementation detail, of changing the pool's
error_if_no_space setting, needs to be reset back to the default that
the user specified when the thin-pool's table was loaded.
Otherwise we'll drop the user requested behaviour on the floor when this
out-of-data-space to write mode transition occurs.

When we set and later readback a frequency value through
sysfs interface, igt/pm_rpm assumes that we get same value back
if it matches hw granularity.
On bxt we have found out that this is not always the case.
Currently frequency - hw ratio - frequency conversions round down,
with few exceptions on platforms that have more specific conversions.
On bxt the supported range can be for example from 100Mhz to 650Mhz.
Midpoint is then calculated by test to be 375 which pm_rps uses to find a
closest hw supported frequency. That is 366 (ratio 22),
which it then writes back. But as the rounding down kicks in,
driver actually sets 350 instead of 366, as 366 is 2/3 below 22 * 50/3.
Fix this by rounding to closest instead of rounding down in
freq-ratio-freq conversions.
