GCC appears to have kind of fragile inlining heuristics, in the
sense that it can change whether or not it inlines something based on
optimizations. It looks like the kcov instrumentation being added (or in
this case, removed) from a function changes the optimization results,
and some functions marked "inline" are _not_ inlined. In that case,
we end up with __init code calling a function not marked __init, and we
get the build warnings I'm trying to eliminate in the coming patch that
adds __no_sanitize_coverage to __init functions:
WARNING: modpost: vmlinux: section mismatch in reference: xbc_exit+0x8 (section: .text.unlikely) -> _xbc_exit (section: .init.text)

WARNING: modpost: vmlinux: section mismatch in reference: efi_config_table_is_usable+0x16 (section: .text.unlikely) -> xen_efi_config_table_is_usable (section: .init.text)
This problem is somewhat fragile (though using either __always_inline
or __init will deterministically solve it), but we've tripped over
this before with GCC and the solution has usually been to just use
__always_inline and move on.
For x86 this means forcing several functions to be inline with
__always_inline.

The pidfd selftests run in userspace and include both userspace and kernel
header files. On some distros (for example, CentOS), this results in
duplicate-symbol warnings in allmodconfig builds, while on other distros
(for example, Ubuntu) it does not.
Therefore, use #undef to get rid of the userspace definitions in favor
of the kernel definitions.
Other ways of handling this include splitting up the selftest code so
that the userspace definitions go into one translation unit and the
kernel definitions into another (which might or might not be feasible)
or to adjust compiler command-line options to suppress the warnings
(which might or might not be desirable).

Tested on SG2042 Pioneer Box, read, write operations.
Thanks Chen Wang who provided machine and guidance.
One more improvement for the T-HEAD TH1520 clock controller this cycle:
Yao Zi has fixed an issue where the c910 mux clk could end up as an
orphan in CCF when the bootloader reparents it to the c910-i0 mux clk.
The solution is to refactor the handling of mux clocks by embedding a
clk_mux structure directly in ccu_mux. This allows the mux clocks to be
registered with devm_clk_hw_register() without allocating any new clk_hw
pointer which solves the orphan issue.
This change has been tested in linux-next. The LPi4a still boots okay
without clk_ignore_unused and peripherals like serial, emmc and ethernet
are functional. The file /sys/kernel/debug/clk/c910/clk_possible_parents
now correctly outputs: "c910-i0 cpu-pll1"

The subsystem event test enables all "sched" events and makes sure there's
at least 3 different events in the output. It used to cat the entire trace
file to | wc -l, but on slow machines, that could last a very long time.
To solve that, it was changed to just read the first 100 lines of the
trace file. This can cause false failures as some events repeat so often,
that the 100 lines that are examined could possibly be of only one event.
Instead, create an awk script that looks for 3 different events and will
exit out after it finds them. This will find the 3 events the test looks
for (eventually if it works), and still exit out after the test is
satisfied and not cause slower machines to run forever.

Add doorbell support by allocating a dedicated BAR using the
pci_epf_alloc_doorbell() API and mapping the Endpoint MSI controller
message data address to it. The data to be written in the message address
is stored in the 'pci_epf_test_reg::doorbell_data' register. Finally, the
RC can trigger doorbell in the Endpoint by writing the content of
'doorbell_data' register to the offset specified in 'doorbell_offset' of
the 'doorbell_bar' BAR.
Triggering of the doorbell is detected by pci_epf_test_doorbell_handler(),
which is bound to the doorbell IRQ. On successful completion,
STATUS_DOORBELL_SUCCESS status is set in the above mentioned handler.
To avoid breaking compatibility between host and endpoint, add two new
commands: COMMAND_ENABLE_DOORBELL and COMMAND_DISABLE_DOORBELL.
The doorbell is allocated when COMMAND_ENABLE_DOORBELL command is called
and destroyed when COMMAND_DISABLE_DOORBELL is called.
This doorbell feature only works when both RC and EP drivers support it.
If one of them doesn't support the feature, the testcase will fail.

Some MSI controllers can change address/data pair during the execution of
irq_chip::irq_set_affinity() callback. Since the current PCI Endpoint
framework cannot support mutable MSI controllers, call
irq_domain_is_msi_immutable() API to check if the controller is immutable
or not.
Also ensure that the MSI domain is a parent MSI domain so that it can
allocate address/data pairs.

Implement the doorbell feature by mapping the EP's MSI interrupt controller
message address to a dedicated BAR.
The EPF driver should pass the actual message data to be written to the
message address by the host through implementation-specific logic.
