c966182752 Fix up more non-executable files marked executable
Joe found another DT file that shouldn't be executable, and that
frustrated me enough that I went hunting with this script:

    git ls-files -s |
        grep '^100755' |
        cut -f2 |
        xargs grep -L '^#!'

and that found another file that shouldn't have been marked executable
either, despite being in the scripts directory.

Maybe these two are the last ones at least for now.  But I'm sure we'll
be back in a few years, fixing things up again.

a44b765148 netfilter: conntrack: unify established states for SCTP paths
An SCTP endpoint can start an association through a path and tear it
down over another one. That means the initial path will not see the
shutdown sequence, and the conntrack entry will remain in ESTABLISHED
state for 5 days.

By merging the HEARTBEAT_ACKED and ESTABLISHED states into one
ESTABLISHED state, there remains no difference between a primary or
secondary path. The timeout for the merged ESTABLISHED state is set to
210 seconds (hb_interval * max_path_retrans + rto_max). So, even if a
path doesn't see the shutdown sequence, it will expire in a reasonable
amount of time.

With this change in place, there is now more than one state from which
we can transition to ESTABLISHED, COOKIE_ECHOED and HEARTBEAT_SENT, so
handle the setting of ASSURED bit whenever a state change has happened
and the new state is ESTABLISHED. Removed the check for dir==REPLY since
the transition to ESTABLISHED can happen only in the reply direction.

   - mei driver/bus fixes and new device ids
   - interconnect driver fixes for reported problems
   - vmci bugfix

 Almost all of these have been in linux-next with no reported problems,
 the rest have all passed 0-day bot testing in my tree and on the mailing
 lists where they have sat too long due to me taking a long time to catch
 up on my pending patch queue.

1ed46384f8 ARM: SoC DT and driver fixes 6.2
Lots of dts fixes for Qualcomm Snapdragon and NXP i.MX platforms,
 including:
 
  - A regression fix for SDHCI controllers on Inforce 6540, and
    another SDHCI fix on SM8350
 
  - Reenable cluster idle on sm8250 after the the code fix is upstream
 
  - multiple fixes for the QMP PHY binding, needing an incompatible
    dt change
 
  - The reserved memory map is updated on Xiaomi Mi 4C and Huawei Nexus
    6P, to avoid instabilities caused by use of protected memory regions
 
  - Fix i.MX8MP DT for missing GPC Interrupt, power-domain typo and USB
    clock error
 
  - A couple of verdin-imx8mm DT fixes for audio playback support
 
  - Fix pca9547 i2c-mux node name for i.MX and Vybrid device trees
 
  - Fix an imx93-11x11-evk uSDHC pad setting problem that causes Micron
    eMMC CMD8 CRC error in HS400ES/HS400 mode
 
 The remaining ARM and RISC-V platforms only have very few
 smaller dts bugfixes this time:
 
  - A fix for the SiFive unmatched board's PCI memory space
 
  - A revert to fix a regression with GPIO on Marvell Armada
 
  - A fix for the UART address on Marvell AC5
 
  - Missing chip-select phandles for stm32 boards
 
  - Selecting the correct clock for the sam9x60 memory controller
 
  - Amlogic based Odroid-HC4 needs a revert to restore USB
    functionality.
 
 And finally, there are some minor code fixes:
 
  - Build fixes for OMAP1, pxa, riscpc, raspberry pi firmware, and zynq
    firmware
 
  - memory controller driver fixes for an OMAP regression and older bugs
    on tegra, atmel and mvebu
 
  - reset controller fixes for ti-sci and uniphier platforms
 
  - ARM SCMI firmware fixes for a couple of rare corner cases
 
  - Qualcomm platform driver fixes for incorrect error handling and a
    backwards compatibility fix for the apr driver using older dtb
 
  - NXP i.MX SoC driver fixes for HDMI output, error handling in the imx8
    soc-id and missing reference counting on older cpuid code

0a4eecf96c dt-bindings: i2c: renesas,rzv2m: Fix SoC specific string
The preferred form for Renesas' compatible strings is:
"<vendor>,<family>-<module>"

Somehow the compatible string for the r9a09g011 I2C IP was upstreamed
as renesas,i2c-r9a09g011 instead of renesas,r9a09g011-i2c, which
is really confusing, especially considering the generic fallback
is renesas,rzv2m-i2c.

The first user of renesas,i2c-r9a09g011 in the kernel is not yet in
a kernel release, it will be in v6.1, therefore it can still be
fixed in v6.1.
Even if we don't fix it before v6.2, I don't think there is any
harm in making such a change.

s/renesas,i2c-r9a09g011/renesas,r9a09g011-i2c/g for consistency.

8c29f01654 x86/sev: Add SEV-SNP guest feature negotiation support
The hypervisor can enable various new features (SEV_FEATURES[1:63]) and start a
SNP guest. Some of these features need guest side implementation. If any of
these features are enabled without it, the behavior of the SNP guest will be
undefined.  It may fail booting in a non-obvious way making it difficult to
debug.

Instead of allowing the guest to continue and have it fail randomly later,
detect this early and fail gracefully.

The SEV_STATUS MSR indicates features which the hypervisor has enabled.  While
booting, SNP guests should ascertain that all the enabled features have guest
side implementation. In case a feature is not implemented in the guest, the
guest terminates booting with GHCB protocol Non-Automatic Exit(NAE) termination
request event, see "SEV-ES Guest-Hypervisor Communication Block Standardization"
document (currently at https://developer.amd.com/wp-content/resources/56421.pdf),
section "Termination Request".

Populate SW_EXITINFO2 with mask of unsupported features that the hypervisor can
easily report to the user.

More details in the AMD64 APM Vol 2, Section "SEV_STATUS MSR".

  [ bp:
    - Massage.
    - Move snp_check_features() call to C code.
    Note: the CC:stable@ aspect here is to be able to protect older, stable
    kernels when running on newer hypervisors. Or not "running" but fail
    reliably and in a well-defined manner instead of randomly. ]

d60c471a86 phy: Revert "phy: qualcomm: usb28nm: Add MDM9607 init sequence"
This reverts commit 557a28811c.

This commit introduced an init sequence from downstream DT [1] in the
driver.  As mentioned by the comment above the HSPHY_INIT_CFG macro for
this sequence:

    /*
     * The macro is used to define an initialization sequence.  Each tuple
     * is meant to program 'value' into phy register at 'offset' with 'delay'
     * in us followed.
     */

Instead of corresponding to offsets into the phy register, the sequence
read by the downstream driver [2] is passed into ulpi_write [3] which
crafts the address-value pair into a new value and writes it into the
same register at USB_ULPI_VIEWPORT [4].  In other words, this init
sequence is programmed into the hardware in a totally different way than
downstream and is unlikely to achieve the desired result, if the hsphy
is working at all.

An alternative method needs to be found to write these init values at
the desired location.  Fortunately mdm9607 did not land upstream yet [5]
and should have its compatible revised to use the generic one, instead
of a compatible that writes wrong data to the wrong registers.

689968db7b sound fixes for 6.2-rc4
This became a slightly big update, but it's more or less expected,
 as the first batch after holidays.
 
 All changes (but for the last two last-minute fixes) have been
 stewed in linux-next long enough, so it's fairly safe to take.
 
 - PCM UAF fix in 32bit compat layer
 - ASoC board-specific fixes for Intel, AMD, Medathek, Qualcomm
 - SOF power management fixes
 - ASoC Intel link failure fixes
 - A series of fixes for USB-audio regressions
 - CS35L41 HD-audio codec regression fixes
 - HD-audio device-specific fixes / quirks
 
 Note that one SPI patch has been taken in ASoC subtree mistakenly,
 and the same fix is found in spi tree, but it should be OK to apply.

Pull arm64 fixes from Will Deacon:
 "Here's a sizeable batch of Friday the 13th arm64 fixes for -rc4. What
  could possibly go wrong?

  The obvious reason we have so much here is because of the holiday
  season right after the merge window, but we've also brought back an
  erratum workaround that was previously dropped at the last minute and
  there's an MTE coredumping fix that strays outside of the arch/arm64
  directory.

  Summary:

   - Fix PAGE_TABLE_CHECK failures on hugepage splitting path

   - Fix PSCI encoding of MEM_PROTECT_RANGE function in UAPI header

   - Fix NULL deref when accessing debugfs node if PSCI is not present

   - Fix MTE core dumping when VMA list is being updated concurrently

   - Fix SME signal frame handling when SVE is not implemented by the
     CPU

   - Fix asm constraints for cmpxchg_double() to hazard both words

   - Fix build failure with stack tracer and older versions of Clang

   - Bring back workaround for Cortex-A715 erratum 2645198"

e695bc7e54 Merge tag 'drm-msm-fixes-2023-01-12' of https://gitlab.freedesktop.org/drm/msm into drm-fixes
msm-fixes for v6.3-rc4

Display Fixes:

- Fix the documentation for dpu_encoder_phys_wb_init() and
  dpu_encoder_phys_wb_setup_fb() APIs to address doc warnings
- Remove vcca-supply and vdds-supply as mandatory for 14nm PHY and
  10nm PHY DT schemas respectively as they are not present on some
  SOCs using these PHYs
- Add the dsi-phy-regulator-ldo-mode to dsi-phy-28nm.yaml as it was
  missed out during txt to yaml migration
- Remove operating-points-v2 and power-domain as a required property
  for the DSI controller as thats not the case for every SOC
- Fix the description from display escape clock to display core
  clock in the dsi controller yaml
- Fix the memory leak for mdp1-mem path for the cases when we return
  early after failing to get mdp0-mem ICC paths for msm
- Fix error handling path in msm_hdmi_dev_probe() to release the phy
  ref count when devm_pm_runtime_enable() fails
- Fix the dp_aux_isr() routine to make sure it doesnt incorrectly
  signal the aux transaction as complete if the ISR was not an AUX
  isr. This fixes a big hitter stability bug on chromebooks.
- Add protection against null pointer dereference when there is no
  kms object as in the case of headless adreno GPU in the shutdown
  path.

GPU Fixes:

- a5xx: fix quirks to actually be a bitmask and not overwrite each
  other
- a6xx: fix gx halt sequence to avoid 1000ms hang on some devices
- kexec shutdown fix
- fix potential double free

310bc39546 KVM: x86/xen: Avoid deadlock by adding kvm->arch.xen.xen_lock leaf node lock
In commit 14243b3871 ("KVM: x86/xen: Add KVM_IRQ_ROUTING_XEN_EVTCHN
and event channel delivery") the clever version of me left some helpful
notes for those who would come after him:

       /*
        * For the irqfd workqueue, using the main kvm->lock mutex is
        * fine since this function is invoked from kvm_set_irq() with
        * no other lock held, no srcu. In future if it will be called
        * directly from a vCPU thread (e.g. on hypercall for an IPI)
        * then it may need to switch to using a leaf-node mutex for
        * serializing the shared_info mapping.
        */
       mutex_lock(&kvm->lock);

In commit 2fd6df2f2b ("KVM: x86/xen: intercept EVTCHNOP_send from guests")
the other version of me ran straight past that comment without reading it,
and introduced a potential deadlock by taking vcpu->mutex and kvm->lock
in the wrong order.

Solve this as originally suggested, by adding a leaf-node lock in the Xen
state rather than using kvm->lock for it.

kvm->srcu is taken in KVM_RUN and several other vCPU ioctls, therefore
vcpu->mutex is susceptible to the same deadlock that is documented
for kvm->slots_lock.  The same holds for kvm->lock, since kvm->lock
is held outside vcpu->mutex.  Fix the documentation and rearrange it
to highlight the difference between these locks and kvm->slots_arch_lock,
and how kvm->slots_arch_lock can be useful while processing a vmexit.

45e966fcca KVM: x86: Do not return host topology information from KVM_GET_SUPPORTED_CPUID
Passing the host topology to the guest is almost certainly wrong
and will confuse the scheduler.  In addition, several fields of
these CPUID leaves vary on each processor; it is simply impossible to
return the right values from KVM_GET_SUPPORTED_CPUID in such a way that
they can be passed to KVM_SET_CPUID2.

The values that will most likely prevent confusion are all zeroes.
Userspace will have to override it anyway if it wishes to present a
specific topology to the guest.

31abfdda65 docs: Deprecate use of Sphinx < 2.4.x
The Sphinx 2.4 release is three years old, and it is becoming increasingly
difficult to even find a system with an sufficiently archaic Python
installation that can run versions older than that.  I can no longer test
changes against anything prior to 2.4.x.

Move toward raising our minimum Sphinx requirement to 2.4.x so we can
delete some older support code and claim to support a range of versions
that we can actually test.

In the absence of screams, the actual removal of support can happen later
in 2023.

0283189e8f docs: Fix the docs build with Sphinx 6.0
Sphinx 6.0 removed the execfile_() function, which we use as part of the
configuration process.  They *did* warn us...  Just open-code the
functionality as is done in Sphinx itself.

Tested (using SPHINX_CONF, since this code is only executed with an
alternative config file) on various Sphinx versions from 2.5 through 6.0.

Merge patch series "riscv,isa fixups"
Conor Dooley <conor@kernel.org> says:

From: Conor Dooley <conor.dooley@microchip.com>

I noticed ~today~ while looking at the isa manual that I had not
accounted for another couple of edge cases with my regex. As before, I
think attempting to validate the canonical order for multiletter stuff
makes no sense - but we should totally try to avoid false-positives for
combinations that are known to be valid.

dt-bindings: riscv: fix single letter canonical order
I used the wikipedia table for ordering extensions when updating the
pattern here in commit 299824e68b ("dt-bindings: riscv: add new
riscv,isa strings for emulators").

Unfortunately that table did not match canonical order, as defined by
the RISC-V ISA Manual, which defines extension ordering in (what is
currently) Table 41, "Standard ISA extension names". Fix things up by
re-sorting v (vector) and adding p (packed-simd) & j (dynamic
languages). The e (reduced integer) and g (general) extensions are still
intentionally left out.
