The difference between 'make clean' and 'make mrproper' is documented in
'make help' as:
clean - Remove most generated files but keep the config and
enough build support to build external modules
mrproper - Remove all generated files + config + various backup files
After commit 68b4fe32d7 ("kbuild: Add objtool to top-level clean
target"), running 'make clean' then attempting to build an external
module with the resulting build directory fails with
$ make ARCH=x86_64 O=build clean
$ make -C build M=... MO=...

Split the objtool clean target into mrproper and clean like Kbuild does
and remove all generated artifacts with 'make clean' except for the
objtool binary, which is removed with 'make mrproper'. To avoid a small
race when running the objtool clean target through both objtool_mrproper
and objtool_clean when running 'make mrproper', modify objtool's clean
up find command to avoid using find's '-delete' command by piping the
files into 'xargs rm -f' like the rest of Kbuild does.

When determining whether or not a WRMSR with reserved bits will #GP or
succeed due to the WRMSR not existing per the guest virtual CPU model,
expect failure if and only if _all_ features associated with the MSR are
unsupported. Checking only the primary feature results in false failures
when running on AMD and Hygon CPUs with only one of RDPID or RDTSCP, as
AMD/Hygon CPUs ignore MSR_TSC_AUX[63:32], i.e. don't treat the bits as
reserved, and so #GP only if the MSR is unsupported.

Most of KVM x86 selftests for AMD are compatible with Hygon architecture
(but not all), add a flag "host_cpu_is_amd_compatible" to figure out
these cases.
Following test failures on Hygon platform can be fixed:
* Fix hypercall test: Hygon architecture also uses VMMCALL as guest
hypercall instruction.
* Following test failures due to access reserved memory address regions:
- access_tracking_perf_test
- demand_paging_test
- dirty_log_perf_test
- dirty_log_test
- kvm_page_table_test
- memslot_modification_stress_test
- pre_fault_memory_test
- x86/dirty_log_page_splitting_test
Hygon CSV also makes the "physical address space width reduction", the
reduced physical address bits are reported by bits 11:6 of
CPUID[0x8000001f].EBX as well, so the existed logic is totally
applicable for Hygon processors. Mapping memory into these regions and

Use guard() and scoped_guard() to replace manual mutex lock/unlock
calls. This simplifies error handling and ensures RAII-style cleanup.
guard() is used in read_raw, write_raw, trig_reen, and
trigger_set_state. Case blocks using guard() in read_raw and write_raw
are wrapped in braces at the case label level to ensure clear scope for
the cleanup guards.
A bmc150_magn_set_power_mode_locked() helper is added to deduplicate
the lock-call-unlock pattern used by remove, runtime_suspend, suspend,
and resume.
The trigger_handler function is left unchanged as mixing guard() with
goto error paths can be fragile.

During recovery of an MLO setup from a core reset,
ATH12K_GROUP_FLAG_REGISTERED is set because ath12k_mac_unregister is not
called during core reset. So, when an MLO setup is recovering from a core
reset, ath12k_core_mlo_setup() is skipped. Hence, the firmware will not
have information about partner links. This makes MLO association fail
after recovery.
To resolve this, call ath12k_core_mlo_setup() during recovery, to set up
MLO. Also, if MLO setup fails during recovery, call
ath12k_mac_unregister() and ath12k_mac_destroy() to unregister mac and
then tear down the mac structures.
Also, initiate MLO teardown in the hardware group stop sequence to align
with the hardware group start sequence.

Add a new IIO_DECLARE_QUATERNION() macro that is used to declare the
field in an IIO buffer struct that contains a quaternion vector.
Quaternions are currently the only IIO data type that uses the .repeat
feature of struct iio_scan_type. This has an implicit rule that the
element in the buffer must be aligned to the entire size of the repeated
element. This macro will make that requirement explicit. Since this is
the only user, we just call the macro IIO_DECLARE_QUATERNION() instead
of something more generic.

The ADE9000_ST_ERROR macro references ADE9000_ST1_ERROR0
through ADE9000_ST1_ERROR3, but the actual defined symbols
use the BIT suffix. Since this macro is currently unused
in the driver, remove it entirely rather than fixing the names.
It can be reintroduced in a future patch when it is actually needed.
The individual error bit definitions (bits 28-31 of the STATUS1
register at 0x403) are retained as they follow the convention of
defining all register fields.
Reference: ADE9000 datasheet (Rev. B, Page 61), STATUS1 register
(0x403), bits 28-31 define ERROR0 through ERROR3 status flags.

As there is no threaded handler, replace devm_request_threaded_irq()
with devm_request_irq(), and as the handler calls iio_trigger_poll()
which may not be called from a threaded handler replace IRQF_ONESHOT
with IRQF_NO_THREAD.
Since commit aef30c8d56 ("genirq: Warn about using IRQF_ONESHOT
without a threaded handler"), the IRQ core checks IRQF_ONESHOT flag
in IRQ request and gives a warning if there is no threaded handler.

Currently xe_lrc_init() does two things.
1. Allocates LRC bo based on exec queue parameters.
2. Initializes LRC bo with actual context details.
Introduce xe_lrc_ctx_init() and split these two implementations for
better maintainability.

devm_request_threaded_irq already prints an error message when failure,
so the error message is redundant, drop it.
