208a352a54 KVM VMX changes for 6.11
- Remove an unnecessary EPT TLB flush when enabling hardware.
 
  - Fix a series of bugs that cause KVM to fail to detect nested pending posted
    interrupts as valid wake eents for a vCPU executing HLT in L2 (with
    HLT-exiting disable by L1).
 
  - Misc cleanups

  - Rework the sched_in/out() paths to replace kvm_arch_sched_in() with a flag
    that arch code can use for hooking both sched_in() and sched_out().
 
  - Take the vCPU @id as an "unsigned long" instead of "u32" to avoid
    truncating a bogus value from userspace, e.g. to help userspace detect bugs.
 
  - Mark a vCPU as preempted if and only if it's scheduled out while in the

    memory when retrieving guest state during live migration blackout.

ASoC: Intel: Fix RT5650 SSP lookup
Commit 8efcd48646 ("ASoC: Intel: sof_rt5682: use common module for
sof_card_private initialization") migrated the pin assignment in the
context struct up to soc-acpi-intel-ssp-common.c. This uses a lookup
table to see if a device has a amp/codec before assigning the pin. The
issue here arises when combination parts that serve both (with 2 ports)
are used.

kobject: kobject_add_internal failed for SSP0-Codec with -EEXIST, don't try to register things with the same name in the same directory.

The issue is that the ALC5650 was only defined in the codec table and
not the amp table which left the pin unassigned but the dai link was
still created by the machine driver.

Also patch the suffix filename code for the topology to prevent double
suffix names as a result of this change.

ASOC: SOF: Intel: hda-loader: only wait for HDaudio IOC for IPC4 devices
Multiple users report a regression bisected to commit d5263dbbd8
("ASoC: SOF: Intel: don't ignore IOC interrupts for non-audio
transfers"). The firmware version is the likely suspect, as these
users relied on SOF 2.0 while Intel only tested with the 2.2 release.

Rather than completely disable the wait_for_completion(), which can
help us gather timing information on the different stages of the boot
process, the simplest course of action is to just disable it for older
IPC versions which are no longer under active development.

3f45181358 tcp: Don't access uninit tcp_rsk(req)->ao_keyid in tcp_create_openreq_child().
syzkaller reported KMSAN splat in tcp_create_openreq_child(). [0]

The uninit variable is tcp_rsk(req)->ao_keyid.

tcp_rsk(req)->ao_keyid is initialised only when tcp_conn_request() finds
a valid TCP AO option in SYN.  Then, tcp_rsk(req)->used_tcp_ao is set
accordingly.

Let's not read tcp_rsk(req)->ao_keyid when tcp_rsk(req)->used_tcp_ao is
false.

platform/x86/intel/tpmi/plr: Fix output in plr_print_bits()
Smatch complains that 'str' can be used without being initialized:

    drivers/platform/x86/intel/intel_plr_tpmi.c:178 plr_print_bits()
    error: uninitialized symbol 'str'.

In this loop, we iterate over all the set bits and print the name of the
bit.  The intention is that if there is a bit which is between 0-31 we
look for the name in the first array plr_coarse_reasons[] which has 10
elements.  If the bit is in the 32-63 range we look for it in the
plr_fine_reasons[] array which has 30 elements.  If the bit is in the
invalid ranges, 10-31 or 62-63, then we should print "UNKNOWN(%d)".

The problem is that 'str' needs to be initialized at the start of each
iteration, otherwise if we can't find the string then instead of printing
"UNKNOWN(%d)", we will re-print whatever the previous bit was.

Intel N100 system / DELL UD22 dock, the LTTPR residing either on the
host or the dock. To fix the issue, keep the current mode on an active
link, adjusting the LTTPR count accordingly (resetting it to 0 in
transparent mode).

v2: Adjust code comment during link training about reiniting the LTTPRs.

d13e2a6e95 drm/i915/dp: Reset intel_dp->link_trained before retraining the link
Regularly retraining a link during an atomic commit happens with the
given pipe/link already disabled and hence intel_dp->link_trained being
false. Ensure this also for retraining a DP SST link via direct calls to
the link training functions (vs. an actual commit as for DP MST). So far
nothing depended on this, however the next patch will depend on
link_trained==false for changing the LTTPR mode to non-transparent.

8bfd6f0923 kconfig: call expr_eliminate_yn() at least once in expr_eliminate_dups()
Kconfig simplifies expressions, but redundant '&&' and '||' operators
involving constant symbols 'y' and 'n' are sometimes trimmed and
sometimes not.

[Test Code]

    config DEP
            def_bool y

    config A
            bool "A"
            depends on DEP && y

    config B
            bool "B"
            depends on DEP && y && y

[Result]

    $ make helpnewconfig
      [ snip ]
    -----

    There is no help available for this option.
    Symbol: A [=n]
    Type  : bool
    Defined at Kconfig:4
      Prompt: A
      Depends on: DEP [=y] && y [=y]
      Location:
        -> A (A [=n])

    -----
    -----

    There is no help available for this option.
    Symbol: B [=n]
    Type  : bool
    Defined at Kconfig:8
      Prompt: B
      Depends on: DEP [=y]
      Location:
        -> B (B [=n])

    -----

The dependency for A, 'DEP && y', remains as-is, while that for B,
'DEP && y && y', has been reduced to 'DEP'.

Currently, expr_eliminate_dups() calls expr_eliminate_yn() only when
trans_count != 0, in other words, only when expr_eliminate_dups1() has
trimmed at least one leaf. It fails to trim a single '&& y', etc.

To fix this inconsistent behavior, expr_eliminate_yn() should be called
at least once even if no leaf has been trimmed.

d67015eedd kbuild: deb-pkg: use default string when variable is unset or null
${DEBFULLNAME-${user}} falls back to ${user} when DEBFULLNAME is unset.
It is more reasonable to do so when DEBFULLNAME is unset or null.

Otherwise, the command:

  $ DEBFULLNAME= make deb-pkg

will leave the name field blank.

The same applies to KBUILD_BUILD_USER and KBUILD_BUILD_HOST.

Commit f5983dab0e ("modpost: define more R_ARM_* for old

build errors on CentOS 7.

RHEL/CentOS 7 were retired at the end of June.

Remove all the R_ARM_* definitions (except for R_ARM_THM_CALL), which
should be available in recent distributions.

glibc and musl added most of R_ARM_* macros in 2013. [1] [2]

5f99665ee8 kbuild: raise the minimum GNU Make requirement to 4.0
RHEL/CentOS 7, popular distributions that install GNU Make 3.82, reached
EOM/EOL on June 30, 2024. While you may get extended support, it is a
good time to raise the minimum GNU Make version.

The new requirement, GNU Make 4.0, was released in October, 2013.

I did not touch the Makefiles under tools/ because I do not know the
requirements for building tools. I do not find any GNU Make version
checks under tools/.

712aba5543 kbuild: avoid build error when single DTB is turned into composite DTB
As commit afa974b771 ("kbuild: add real-prereqs shorthand for
$(filter-out FORCE,$^)") explained, $(real-prereqs) is not just a list
of objects when linking a multi-object module. If a single-object module
is turned into a multi-object module, $^ (and therefore $(real-prereqs)
as well) contains header files recorded in the *.cmd file. Such headers
must be filtered out.

Now that a DTB can be built either from a single source or multiple
source files, the same issue can occur.

Consider the following scenario:

First, foo.dtb is implemented as a single-blob device tree.

The code looks something like this:

[Sample Code 1]

  Makefile:

      dtb-y += foo.dtb

  foo.dts:

    #include <dt-bindings/gpio/gpio.h>
    /dts-v1/;
    / { };

When it is compiled, .foo.dtb.cmd records that foo.dtb depends on
scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h.

Later, foo.dtb is split into a base and an overlay. The code looks
something like this:

[Sample Code 2]

  Makefile:

      dtb-y += foo.dtb
      foo-dtbs := foo-base.dtb foo-addon.dtbo

  foo-base.dts:

    #include <dt-bindings/gpio/gpio.h>
    /dts-v1/;
    / { };

  foo-addon.dtso:

    /dts-v1/;
    /plugin/;
    / { };

If you rebuild foo.dtb without 'make clean', you will get this error:

    Overlay 'scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h' is incomplete

$(real-prereqs) contains not only foo-base.dtb and foo-addon.dtbo but
also scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h, which is
passed to scripts/dtc/fdtoverlay.

Set -u because these scripts are invoked by Makefile, and do not work

Remove the explicit "test -n ..." from install-extmod-build.

0c60eb0cc3 scsi: ufs: core: Check LSDBS cap when !mcq
If the user sets use_mcq_mode to 0, the host will try to activate the LSDB
mode unconditionally even when the LSDBS of device HCI cap is 1. This makes
commands time out and causes device probing to fail.

To prevent that problem, check the LSDBS cap when MCQ is not supported.
