Here are some tiny USB and Thunderbolt driver fixes and quirks, for
6.0-final.
Included in here are:
- 3 uas/usb-storage driver quirks to get the devices working
properly due to broken firmware images in them (they can not
run at high data rates, and are also throttled on other
operating systems because of this.)
- thunderbolt bugfix for plug event delays
- typec runtime warning removal
- dwc3 st driver bugfix. Note, a follow-on fix for this will
end up coming in for 6.1-rc1 as the developers are still
arguing over what the final solution will be, but this should
be sufficient for now.
All of these have been in linux-next with no reported problems.

Nearly all other firmware environments have some way of passing a RNG
seed to initialize the RNG: DTB's rng-seed, EFI's RNG protocol, m68k's
bootinfo block, x86's setup_data, and so forth. This adds something
similar for MIPS, which will allow various firmware environments,
bootloaders, and hypervisors to pass an RNG seed to initialize the
kernel's RNG.

We enable -Wcast-function-type globally in the kernel to warn about
mismatching types in function pointer casts. Compilers currently
warn only about ABI incompability with this flag, but Clang 16 will
enable a stricter version of the check by default that checks for an
exact type match. This will be very noisy in the kernel, so disable
-Wcast-function-type-strict without W=1 until the new warnings have
been addressed.

patches fix serious problems, for example, i.MX has an issue where
changing the NAND clk frequency hangs the system. On Allwinner H6 the
GPU is being overclocked which could lead to long term hardware damage.
And finally on some Broadcom SoCs the serial console stopped working
because the clk tree hierarchy description got broken by an inadvertant
DT node name change. That's fixed by using 'clock-output-names' to
generate a stable and unique name for clks so the framework can properly
link things up.
There's also a couple build fixes in here. One to fix CONFIG_OF=n builds
and one to avoid an array out of bounds bug that happens during clk
registration on microchip. I hope that KASAN would have found that OOB
problem, but probably KASAN wasn't attempted. Instead LLVM/clang
compilation caused an oops, while GCC didn't.

After the commit 6505e452371d ("ACPI: LPSS: Use the helper
acpi_dev_get_memory_resources()") the list is empty or
contains only resource of IORESOURCE_MEM type. Hence, no
need to check for the type, and since we break after the
first found, no need to iterate over full list. That said,
replace loop with first entry retrieval.

On one of the Chrome system, if we define more than 12 trip points,
probe for thermal sensor fails with
"int3403 thermal: probe of INTC1046:03 failed with error -22"
and throws an error as
"thermal_sys: Error: Incorrect number of thermal trips".
The thermal_zone_device_register() interface needs maximum
number of trip points supported in a zone as an argument.
This number can't exceed THERMAL_MAX_TRIPS, which is currently
set to 12. To address this issue, THERMAL_MAX_TRIPS value
has to be increased.
This interface also has an argument to specify a mask of trips
which are writable. This mask is defined as an int.
This mask sets the ceiling for increasing maximum number of
supported trips. With the current implementation, maximum number
of trips can be supported is 31.
Also, THERMAL_MAX_TRIPS macro is used in one place only.
So, remove THERMAL_MAX_TRIPS macro and compare num_trips
directly with using a macro BITS_PER_TYPE(int)-1.

It turns out Apple doesn't capitalise the "mini" in "Macmini" in DMI, which
is inconsistent with other model line names.
Correct the capitalisation of Macmini in the quirk for skipping loading
platform certs on T2 Macs.

This reverts commit e4f0a7ec58.
When using this new interface, both efi_pstore and ramoops
backends are unable to properly decompress dmesg if using
zstd, lz4 and lzo algorithms (and maybe more). It does succeed
with deflate though.
The message observed in the kernel log is:
[2.328828] pstore: crypto_acomp_decompress failed, ret = -22!
The pstore infrastructure is able to collect the dmesg with
both backends tested, but since decompression fails it's
unreadable. With this revert everything is back to normal.

Clean up config files by:
- removing configs that were deleted in the past
- removing configs not in tree and without recently pending patches
- adding new configs that are replacements for old configs in the file
For some detailed information, see Link.

Directly compare the expected versus observed hypercall instructions when
verifying that KVM patched in the native hypercall (FIX_HYPERCALL_INSN
quirk enabled). gcc rightly complains that doing a 4-byte memcpy() with
an "unsigned char" as the source generates an out-of-bounds accesses.
Alternatively, "exp" and "obs" could be declared as 3-byte arrays, but
there's no known reason to copy locally instead of comparing directly.

Implement memcmp(), memcpy(), and memset() to override the compiler's
built-in versions in order to guarantee that the compiler won't generate
out-of-line calls to external functions via the PLT. This allows the
helpers to be safely used in guest code, as KVM selftests don't support
dynamic loading of guest code.
Steal the implementations from the kernel's generic versions, sans the
optimizations in memcmp() for unaligned accesses.
Put the utilities in a separate compilation unit and build with
-ffreestanding to fudge around a gcc "feature" where it will optimize
memset(), memcpy(), etc... by generating a recursive call. I.e. the
compiler optimizes itself into infinite recursion. Alternatively, the
individual functions could be tagged with
optimize("no-tree-loop-distribute-patterns"), but using "optimize" for
anything but debug is discouraged, and Linus NAK'd the use of the flag
in the kernel proper[*].

IA32_PLATFORM_DCA_CAP[31:0] in EAX. This MSR doesn't even exist in the

Bail out of test_dump_stack() if the stack trace is empty rather than
invoking addr2line with zero addresses. The problem with the latter is
that addr2line will block waiting for addresses to be passed in via
stdin, e.g. if running a selftest from an interactive terminal.
Opportunistically fix up the comment that mentions skipping 3 frames
since only 2 are skipped in the code.

[Small tweak to keep backtrace() call close to if(). - Paolo]
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Page_idle uses {ptep/pmdp}_clear_young_notify which in turn calls
the mmu notifier callback ->clear_young(), which purposefully
does not flush the TLB.
When running the test in a nested guest, point 1. of the test
doc header is violated, because KVM TLB is unbounded by size
and since no flush is forced, KVM does not update the sptes
accessed/idle bits resulting in guest assertion failure.
More precisely, only the first ACCESS_WRITE in run_test() actually
makes visible changes, because sptes are created and the accessed
bit is set to 1 (or idle bit is 0). Then the first mark_memory_idle()
passes since access bit is still one, and sets all pages as idle
(or not accessed). When the next write is performed, the update
is not flushed therefore idle is still 1 and next mark_memory_idle()
fails.

Now that Clang's -enable-trivial-auto-var-init-zero-knowing-it-will-be-removed-from-clang
option is no longer required, remove it from the command line. Clang 16
and later will warn when it is used, which will cause Kconfig to think
it can't use -ftrivial-auto-var-init=zero at all. Check for whether it
is required and only use it when so.
