imx6ulz is derived SoC from imx6ull.
Currently, the boards based on imx6ulz are correctly recognized only if
the compatible includes "fsl,imx6ull", while "fsl,imx6ulz" is ignored.

The function call ida_simple_get maybe fail,we should deal with it.
And if ida_simple_get success ,it need to call ida_simple_remove also.

Starting from ICL, the default for MIPI GPIO sequences seems to be using
native GPIOs i.e. GPIOs available in the GPU. These native GPIOs reuse
many pins that quite frankly seem scary to poke based on the VBT
sequences. We pretty much have to trust that the board is configured
such that the relevant HPD, PP_CONTROL and GPIO bits aren't used for
anything else.
MIPI sequence v4 also adds a flag to fall back to non-native sequences.
v5:
- Wrap SHOTPLUG_CTL_DDI modification in spin_lock() in icp_irq_handler()
too (Ville)
- References instead of Closes issue 6131 because this does not fix everything
v4:
- Wrap SHOTPLUG_CTL_DDI modification in spin_lock_irq() (Ville)
v3:
- Fix -Wbitwise-conditional-parentheses (kernel test robot <lkp@intel.com>)
v2:
- Fix HPD pin output set (impacts GPIOs 0 and 5)
- Fix GPIO data output direction set (impacts GPIOs 4 and 9)
- Reduce register accesses to single intel_de_rwm()

Guoqing Jiang reports that openSUSE cannot compile the kernel rpm due
to "BuildRequires: elfutils-libelf-devel" added by commit 8818039f959b
("kbuild: add ability to make source rpm buildable using koji").
The relevant package name in openSUSE is libelf-devel.
Add it as an alternative package.
BTW, if it is impossible to solve the build requirement, the final
resort would be:
$ make RPMOPTS=--nodeps rpm-pkg
This passes --nodeps to the rpmbuild command so it will not verify
build dependencies. This is useful to test rpm builds on non-rpm
system. On Debian/Ubuntu, for example, you can install rpmbuild by
'apt-get install rpm'.
NOTE1:
Likewise, it is possible to bypass the build dependency check for
debian package builds:
$ make DPKG_FLAGS=-d deb-pkg
NOTE2:
The 'or' operator is supported since RPM 4.13. So, old distros such
as CentOS 7 will break. I suggest installing newer rpmbuild in such
cases.

commit 3d57e1b7b1d4 ("kbuild: refactor the prerequisites of the modpost
rule") moved 'vmlinux.o' inside modpost-args, possibly before some of
the other options. However, getopt() in musl libc follows POSIX and
stops looking for options upon reaching the first non-option argument.
As a result, the '-T' option is misinterpreted as a positional argument,
and the build fails:
make -f ./scripts/Makefile.modpost
scripts/mod/modpost -E -o Module.symvers vmlinux.o -T modules.order
-T: No such file or directory
make[1]: *** [scripts/Makefile.modpost:137: Module.symvers] Error 1
make: *** [Makefile:1960: modpost] Error 2
The fix is to move all options before 'vmlinux.o' in modpost-args.

Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux
since commit 994b7ac1697b ("arm64: remove special treatment for the
link order of head.o").
The issue is that the type of .notes section, which contains the BuildID,
changed from NOTES to PROGBITS.
Ard Biesheuvel figured out that whichever object gets linked first gets
to decide the type of a section. The PROGBITS type is the result of the
compiler emitting .note.GNU-stack as PROGBITS rather than NOTE.
While Ard provided a fix for arm64, I want to fix this globally because
the same issue is happening on riscv since commit 2348e6bf4421 ("riscv:
remove special treatment for the link order of head.o"). This problem
will happen in general for other architectures if they start to drop
unneeded entries from scripts/head-object-list.txt.
Discard .note.GNU-stack in include/asm-generic/vmlinux.lds.h.

Also, the size check was only being applied to the initial firmware

The catch-all evict can fail due to object lock contention, since it
only goes as far as trylocking the object, due to us already holding the
vm->mutex. Doing a full object lock here can deadlock, since the
vm->mutex is always our inner lock. Add another execbuf pass which drops
the vm->mutex and then tries to grab the object will the full lock,
before then retrying the eviction. This should be good enough for now to
fix the immediate regression with userspace seeing -ENOSPC from execbuf
due to contended object locks during GTT eviction.

- Also revamp the docs for the different passes.

The recent code refactoring for HD-audio HDMI codec driver caused a
regression on AMD/ATI HDMI codecs; namely, PulseAudioand pipewire
don't recognize HDMI outputs any longer while the direct output via
ALSA raw access still works.
The problem turned out that, after the code refactoring, the driver
assumes only the dynamic PCM assignment, and when a PCM stream that
still isn't assigned to any pin gets opened, the driver tries to
assign any free converter to the PCM stream. This behavior is OK for
Intel and other codecs, as they have arbitrary connections between
pins and converters. OTOH, on AMD chips that have a 1:1 mapping
between pins and converters, this may end up with blocking the open of
the next PCM stream for the pin that is tied with the formerly taken
converter.
Also, with the code refactoring, more PCM streams are exposed than
necessary as we assume all converters can be used, while this isn't
true for AMD case. This may change the PCM stream assignment and
confuse users as well.
This patch fixes those problems by:
- Introducing a flag spec->static_pcm_mapping, and if it's set, the
driver applies the static mapping between pins and converters at the
probe time
- Limiting the number of PCM streams per pins, too; this avoids the
superfluous PCM streams

Commit 8fda37cf3d41 ("KVM: selftests: Stuff RAX/RCX with 'safe' values
in vmmcall()/vmcall()", 2022-11-21) broke the svm_nested_soft_inject_test
because it placed a "pop rbp" instruction after vmmcall. While this is
correct and mimics what is done in the VMX case, this particular test
expects a ud2 instruction right after the vmmcall, so that it can skip
over it in the L1 part of the test.
Inline a suitably-modified version of vmmcall() to restore the
functionality of the test.

Currently only the locking order of SRCU vs kvm->slots_arch_lock
and kvm->slots_lock is documented. Extend this to kvm->lock
since Xen emulation got it terribly wrong.

While KVM_XEN_EVTCHN_RESET is usually called with no vCPUs running,
if that happened it could cause a deadlock. This is due to
kvm_xen_eventfd_reset() doing a synchronize_srcu() inside
a kvm->lock critical section.
To avoid this, first collect all the evtchnfd objects in an
array and free all of them once the kvm->lock critical section
is over and th SRCU grace period has expired.

include/uapi/linux/io_uring.h is synced 1:1 into
liburing:src/include/liburing/io_uring.h.
liburing has a configure check to detect the need for
linux/time_types.h. It can opt-out by defining
UAPI_LINUX_IO_URING_H_SKIP_LINUX_TIME_TYPES_H
