The parse_actions() function uses 'len = str_has_prefix()' to test which
action is in the string being parsed. But then it goes and repeats the
logic for each different action. This logic can be simplified and
duplicate code can be removed as 'len' contains the length of the found
prefix which should be used for all actions.

__put_unaligned_be24() and friends use implicit casts to convert

Currently, if the function irq_domain_add_linear() fails to allocate
a new IRQ domain and returns NULL, we would then still return a success
from the xilinx_pl_dma_pcie_init_irq_domain() function regardless, as
the PTR_ERR(NULL) would return a value of zero. This is not a desirable
outcome.
Thus, fix the incorrect error code and return the -ENOMEM error code if
the irq_domain_add_linear() fails to allocate a new IRQ domain.

KVM x86 MMU changes for 6.8:
- Fix a relatively benign off-by-one error when splitting huge pages during
CLEAR_DIRTY_LOG.
- Fix a bug where KVM could incorrectly test-and-clear dirty bits in non-leaf
TDP MMU SPTEs if a racing thread replaces a huge SPTE with a non-huge SPTE.
- Relax the TDP MMU's lockdep assertions related to holding mmu_lock for read
versus write so that KVM doesn't pass "bool shared" all over the place just
to have precise assertions in paths that don't actually care about whether
the caller is a reader or a writer.

KVM Xen change for 6.8:
To workaround Xen guests that don't expect Xen PV clocks to be marked as being
based on a stable TSC, add a Xen config knob to allow userspace to opt out of
KVM setting the "TSC stable" bit in Xen PV clocks. Note, the "TSC stable" bit
was added to the PVCLOCK ABI by KVM without an ack from Xen, i.e. KVM isn't
entirely blameless for the buggy guest behavior.

KVM SVM changes for 6.8:
- Revert a bogus, made-up nested SVM consistency check for TLB_CONTROL.
- Advertise flush-by-ASID support for nSVM unconditionally, as KVM always

allows running bleeding edge versions of VMware Workstation on top of KVM.
- Sanity check that the CPU supports flush-by-ASID when enabling SEV support.
- Fix a benign NMI virtualization bug where KVM would unnecessarily intercept
IRET when manually injecting an NMI, e.g. when KVM pends an NMI and injects
a second, "simultaneous" NMI.

KVM x86 support for virtualizing Linear Address Masking (LAM)
Add KVM support for Linear Address Masking (LAM). LAM tweaks the canonicality
checks for most virtual address usage in 64-bit mode, such that only the most
significant bit of the untranslated address bits must match the polarity of the
last translated address bit. This allows software to use ignored, untranslated
address bits for metadata, e.g. to efficiently tag pointers for address
sanitization.
LAM can be enabled separately for user pointers and supervisor pointers, and
for userspace LAM can be select between 48-bit and 57-bit masking
- 48-bit LAM: metadata bits 62:48, i.e. LAM width of 15.
- 57-bit LAM: metadata bits 62:57, i.e. LAM width of 6.
For user pointers, LAM enabling utilizes two previously-reserved high bits from
CR3 (similar to how PCID_NOFLUSH uses bit 63): LAM_U48 and LAM_U57, bits 62 and
61 respectively. Note, if LAM_57 is set, LAM_U48 is ignored, i.e.:
- CR3.LAM_U48=0 && CR3.LAM_U57=0 == LAM disabled for user pointers
- CR3.LAM_U48=1 && CR3.LAM_U57=0 == LAM-48 enabled for user pointers
- CR3.LAM_U48=x && CR3.LAM_U57=1 == LAM-57 enabled for user pointers
For supervisor pointers, LAM is controlled by a single bit, CR4.LAM_SUP, with
the 48-bit versus 57-bit LAM behavior following the current paging mode, i.e.:
- CR4.LAM_SUP=0 && CR4.LA57=x == LAM disabled for supervisor pointers
- CR4.LAM_SUP=1 && CR4.LA57=0 == LAM-48 enabled for supervisor pointers
- CR4.LAM_SUP=1 && CR4.LA57=1 == LAM-57 enabled for supervisor pointers
The modified LAM canonicality checks:
- LAM_S48 : [ 1 ][ metadata ][ 1 ]
63 47
- LAM_U48 : [ 0 ][ metadata ][ 0 ]
63 47
- LAM_S57 : [ 1 ][ metadata ][ 1 ]
63 56
- LAM_U57 + 5-lvl paging : [ 0 ][ metadata ][ 0 ]
63 56
- LAM_U57 + 4-lvl paging : [ 0 ][ metadata ][ 0...0 ]
63 56..47
The bulk of KVM support for LAM is to emulate LAM's modified canonicality
checks. The approach taken by KVM is to "fill" the metadata bits using the
highest bit of the translated address, e.g. for LAM-48, bit 47 is sign-extended
to bits 62:48. The most significant bit, 63, is *not* modified, i.e. its value
from the raw, untagged virtual address is kept for the canonicality check. This
untagging allows
Aside from emulating LAM's canonical checks behavior, LAM has the usual KVM
touchpoints for selectable features: enumeration (CPUID.7.1:EAX.LAM[bit 26],
enabling via CR3 and CR4 bits, etc.

KVM x86 PMU changes for 6.8:
- Fix a variety of bugs where KVM fail to stop/reset counters and other state
prior to refreshing the vPMU model.
- Fix a double-overflow PMU bug by tracking emulated counter events using a
dedicated field instead of snapshotting the "previous" counter. If the
hardware PMC count triggers overflow that is recognized in the same VM-Exit
that KVM manually bumps an event count, KVM would pend PMIs for both the
hardware-triggered overflow and for KVM-triggered overflow.
|
|
KVM x86 misc changes for 6.8:
- Turn off KVM_WERROR by default for all configs so that it's not
inadvertantly enabled by non-KVM developers, which can be problematic for
subsystems that require no regressions for W=1 builds.
- Advertise all of the host-supported CPUID bits that enumerate IA32_SPEC_CTRL
"features".
- Don't force a masterclock update when a vCPU synchronizes to the current TSC
generation, as updating the masterclock can cause kvmclock's time to "jump"
unexpectedly, e.g. when userspace hotplugs a pre-created vCPU.
- Use RIP-relative address to read kvm_rebooting in the VM-Enter fault paths,
partly as a super minor optimization, but mostly to make KVM play nice with
position independent executable builds.

|
KVM x86 Hyper-V changes for 6.8:

at build time.

KVM_GENERIC_MEMORY_ATTRIBUTES requires the generic MMU notifier code, because
it uses kvm_mmu_invalidate_begin/end. However, it would not work with a bespoke
implementation of MMU notifiers that does not use KVM_GENERIC_MMU_NOTIFIER,
because most likely it would not synchronize correctly on invalidation. So
the right thing to do is to note the problematic configuration if the
architecture does not select itself KVM_GENERIC_MMU_NOTIFIER; not to
enable it blindly.

CONFIG_HAVE_KVM is currently used by some architectures to either
enabled the KVM config proper, or to enable host-side code that is
not part of the KVM module. However, CONFIG_KVM's "select" statement
in virt/kvm/Kconfig corresponds to a third meaning, namely to
enable common Kconfigs required by all architectures that support
KVM.
These three meanings can be replaced respectively by an
architecture-specific Kconfig, by IS_ENABLED(CONFIG_KVM), or by
a new Kconfig symbol that is in turn selected by the
architecture-specific "config KVM".
Start by introducing such a new Kconfig symbol, CONFIG_KVM_COMMON.
Unlike CONFIG_HAVE_KVM, it is selected by CONFIG_KVM, not by
architecture code, and it brings in all dependencies of common
KVM code. In particular, INTERVAL_TREE was missing in loongarch
and riscv, so that is another thing that is fixed.

When OMTP headset plugin the headset jack of CX8070 and SN6160 sound cards,
the headset type detection circuit will recognize the headset type as CTIA.
At this point, plugout and plugin the headset will get the correct headset
type as OMTP.
The reason for the failure of headset type recognition is that the sound
card creation will enable the VREF voltage of the headset mic, which
interferes with the headset type automatic detection circuit. Plugout and
plugin the headset will restart the headset detection and get the correct
headset type.
The patch is disable the VREF voltage when the headset is not present, and
will enable the VREF voltage when the headset is present.

ASoC: Updates for v6.8
This is a relatively quiet release, there's a lot of driver specific
changes and the usual high level of activity in the SOF core but the
one big core change was Mormioto-san's work to support more N:M
CPU:CODEC mapping cases. Highlights include:
- Enhanced support for N:M CPU:CODEC mappings in the core and in
audio-graph-card2.
- Support for falling back to older SOF IPC versions where firmware for
new versions is not available.
- Support for notification of control changes generated by SOF firmware
with IPC4.
- Device tree support for describing parts of the card which can be
active over suspend (for very low power playback or wake word use
cases).
- ACPI parsing support for the ES83xx driver, reducing the number of
quirks neede for x86 systems.
- Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm
SM8250, SM8550, SM8650 and X1E80100.
- Removal of Freescale MPC8610 support, the SoC is no longer supported
by Linux.

smb2_compound_op(SMB2_OP_GET_REPARSE) already checks if ioctl response
has a valid reparse data buffer's length, so there's no need to check
it again in parse_reparse_point().
In order to get rid of duplicate check, validate reparse data buffer's
length also in cifs_query_reparse_point().

As the part of support for legacy layout of configuration ROM, this
commit traverses vendor directory as well as root directory when showing
device attribute for node device. This change expects 'model_name'
attribute appears in node device, however it is probable to see the other
types of descriptor leaf if the vendor directory includes.

Some legacy devices have configuration ROM against standard AV/C device.
They have vendor directory to store model identifier. It is described in
annex of the following document.
- Configuration ROM for AV/C Devices 1.0 (Dec. 12, 2000, 1394 Trading
Association)
In the case, current implementation of core function does not detect the
model identifier, thus device attributes and modalias of unit have lack of
it. Another KUnit test is required for the case, and this commit is for
the purpose.
The following output is the parse result for the hard-coded data, by
config-rom-pretty-printer in linux-firewire-utils
(https://git.kernel.org/pub/scm/utils/ieee1394/linux-firewire-utils.git/).
The data is written by my hand.

At present, core function can handle node which has configuration ROM
similar to standard AV/C device somehow. The standard layout of
configuration ROM is described in the following document.
- Configuration ROM for AV/C Devices 1.0 (Dec. 12, 2000, 1394 Trading
Association)
This commit adds a KUnit test for the above case.
The following output is the parse result for the hard-coded data, by
