Pull in tip/sched/core to resolve two merge conflicts:
- 96fd6c65efc6 ("sched: Factor out update_other_load_avgs() from __update_blocked_others()")
5d871a63997f ("sched/fair: Move effective_cpu_util() and effective_cpu_util() in fair.c")
A simple context conflict. The former added __update_blocked_others() in
the same #ifdef CONFIG_SMP block that effective_cpu_util() and
sched_cpu_util() are in and the latter moved those functions to fair.c.
This makes __update_blocked_others() more out of place. Will follow up
with a patch to relocate.
- 96fd6c65efc6 ("sched: Factor out update_other_load_avgs() from __update_blocked_others()")
84d265281d6c ("sched/pelt: Use rq_clock_task() for hw_pressure")
The former factored out the body of __update_blocked_others() into
update_other_load_avgs(). The latter changed how update_hw_load_avg() is
called in the body. Resolved by applying the change to
update_other_load_avgs() instead.

Avoid unnecessary nested min()/max() which results in egregious macro
expansion.
Use clamp_t() as this introduces the least possible expansion, and turn
the {s,u}DIGIT_FITTING() macros into inline functions to avoid the
nested expansion.
This resolves an issue with slackware 15.0 32-bit compilation as
reported by Richard Narron.
Presumably the min/max fixups would be difficult to backport, this patch
should be easier and fix's Richard's problem in 5.15.

In the pxafb_probe function, it calls the pxafb_init_fbinfo function,
after which &fbi->task is associated with pxafb_task. Moreover,
within this pxafb_init_fbinfo function, the pxafb_blank function
within the &pxafb_ops struct is capable of scheduling work.
If we remove the module which will call pxafb_remove to make cleanup,
it will call unregister_framebuffer function which can call
do_unregister_framebuffer to free fbi->fb through
put_fb_info(fb_info), while the work mentioned above will be used.
The sequence of operations that may lead to a UAF bug is as follows:
CPU0 CPU1
| pxafb_task
pxafb_remove |
unregister_framebuffer(info) |
do_unregister_framebuffer(fb_info) |
put_fb_info(fb_info) |
// free fbi->fb | set_ctrlr_state(fbi, state)
| __pxafb_lcd_power(fbi, 0)
| fbi->lcd_power(on, &fbi->fb.var)
| //use fbi->fb
Fix it by ensuring that the work is canceled before proceeding
with the cleanup in pxafb_remove.
Note that only root user can remove the driver at runtime.

amd_get_boost_ratio_numerator()
The special case in amd_pstate_highest_perf_set() is the value used
for calculating the boost numerator. Merge this into
amd_get_boost_ratio_numerator() and then use that to calculate boost

AMD systems that support preferred cores will use "166" as their
numerator for max frequency calculations instead of "255".
Add a function for detecting preferred cores by looking at the
highest perf value on all cores.
If preferred cores are enabled return 166 and if disabled the
value in the highest perf register. As the function will be called
multiple times, cache the values for the boost numerator and if
preferred cores will be enabled in global variables.

[Why]
DC has a special commit path for native cursor, which use the built-in
cursor pipe within DCN planes. This update path does not require all
enabled planes to be added to the list of surface updates sent to DC.
This is not the case for overlay cursor; it uses the same path as MPO
commits. This update path requires all enabled planes to be added to the
list of surface updates sent to DC. Otherwise, DC will disable planes
not inside the list.
[How]
If overlay cursor is needed, add all planes on the same CRTC as this
cursor to the atomic state. This is already done for non-cursor planes
(MPO), just before the added lines.

The behavior of regulator_dev_lookup() for non-DT way has been broken
since the commit b8c325545714 ("regulator: Move OF-specific regulator
lookup code to of_regulator.c").
Before the commit, of_get_regulator() was used to get the regulator,
which returns NULL if the regulator is not found. So the regulator
will be looked up through regulator_lookup_by_name() if no matching
regulator is found in regulator_map_list.
However, currently, of_regulator_dev_lookup() is used to instead of
of_get_regulator(), but the variable 'r' is set to ERR_PTR(-ENODEV)
instead of NULL if the regulator is not found. In this case, if no
regulator is found in regulator_map_list, the variable 'r' is still
ERR_PTR(-ENODEV), So regulator_dev_lookup() returns the value of 'r'
directly instead of continuing to look up the regulator through
regulator_lookup_by_name().

U-Boot environment variables are stored in a specific format. Actual
data can be placed in various storage sources (MTD, UBI volume, EEPROM,
NVRAM, etc.).
Move all generic (NVMEM device independent) code from NVMEM device
driver to an NVMEM layout driver. Then add a simple NVMEM layout code on
top of it.
This allows using NVMEM layout for parsing U-Boot env data stored in any
kind of NVMEM device.
The old NVMEM glue driver stays in place for handling bindings in the
MTD context. To avoid code duplication it uses exported layout parsing
function. Please note that handling MTD & NVMEM layout bindings may be
refactored in the future.

Implement i.MX8Q (i.MX8QM, i.MX8QXP, and i.MX8DXL) PCIe Root Complex
(RC) support. While the controller resembles that of i.MX8MP, the PHY
differs significantly. Also, there's a distinction between PCI bus
addresses and CPU addresses.
Introduce IMX_PCIE_FLAG_CPU_ADDR_FIXUP in drvdata::flags to indicate driver
need the cpu_addr_fixup() callback to facilitate CPU address to PCI bus
address conversion according to "ranges" property.

kobject_init() which takes a 'const struct kobj_type *ktype'
