The active property of port altmode should be writable (to prevent or
allow partner altmodes from entering) and needs to be part of
typec_altmode_desc so we can initialize the port to an inactive state if
desired.

Mode in struct typec_altmode is used to indicate the index of the
altmode on a port, partner or plug. It is used in enter mode VDMs but
doesn't make much sense for matching against altmode drivers or for
matching partner to port altmodes.

The UDC state in sysfs (/sys/class/udc/<udc>/state) should accurately
reflect the current state of the USB Device Controller.
Currently, the UDC state is not handled consistently during gadget
disconnection. While the disconnect interrupt path correctly sets the
state to "not-attached", manual deconfiguration leaves the state in
"configured", misrepresenting the actual situation.
This commit ensures consistent UDC state handling by setting the state to
"not-attached" after manual deconfiguration. This accurately reflects the
UDC's state and provides a consistent behavior regardless of the
disconnection method.

Fixes issue where memory will fail to be allocated for larger bulk
transfers, ~1 MB or more. This occurs because userland libraries, such
as libusb, send the entire USB data buffer when SG support is detected.
The assumption is that the driver knows how to properly split the data
up before sending it out.
By hardcoding a limit, bigger transfers that exceed the SG tablesize
limit of 32 will be unable to use SG. This results in an attempt to
allocate contiguous pages which, unsurprisingly, will fail too and
returns an ENOMEM. It looks like other drivers that support SG allow for
any length of SG lists. Accepting any SG size allows the driver to
properly handle large bulk transfer situations.
Tested bulk read and write operations using the following devices:
- Logitech Webcam Pro 9000 - USB 2.0
- SanDisk Ultra - USB 3.0
- Logitech M500s Mouse

This commit adds a new AMS for responding to a "Get_Revision" request.
Revision message consists of the following fields:
+----------------------------------------------------+
| Header | RMDO |
| No. of data objects = 1 | |
+----------------------------------------------------+
While RMDO consists of:
* B31..28 Revision Major
* B27..24 Revision Minor
* B23..20 Version Major
* B19..16 Version Minor
* B15..0 Reserved, shall be set to zero.
As per the PD spec ("8.3.3.16.2.1 PR_Give_Revision State"), a request is
only expected when an explicit contract is established and the port is
in ready state. This AMS is only supported for PD >= 3.0.

Add support for parsing "pd-revision" DT property in TCPM and store PD
revision and version supported by the Type-C connnector.
It should be noted that the PD revision is the maximum possible revision
supported by the port. This is different from the 2 bit revision set in
PD msg headers. The purpose of the 2 bit revision value is to negotiate
between Rev 2.X & 3.X spec rev as part of contract negotiation, while
this is used for Get_Revision AMS after a contract is in place.

The TI HD3SS3220 Type-C controller supports configuring
its role preference when operating as a dual-role port
through the SOURCE_PREF field of the General Control Register.
The previous driver behavior was to set the role preference
based on the dr_set typec_operation.
However, the controller does not support swapping the data role
on an active connection due to its lack of Power Delivery support.
Remove previous dr_set typec_operation, and support setting
the role preference based on the corresponding fwnode property,
as well as the try_role typec_operation.

The TI HD3SS3220 Type-C controller supports configuring the port type
it will operate as through the MODE_SELECT field of the General
Control Register.
Configure the port type based on the fwnode property "power-role"
during probe, if present. If the property is absent, leave the
operation mode at the default, which is defined by the PORT pin
of the chip.
Support configuring the port type through the port_type_set
typec_operation as well.
The MODE_SELECT field can only be changed when the controller is in
unattached state, so follow the sequence recommended by the datasheet to:
1. disable termination on CC pins to disable the controller
2. change the mode
3. re-enable termination
This will effectively cause a connected device to disconnect
for the duration of the mode change.

In the function pmc_mux_port_debugfs_init() the buffer for
the name of the port is limited to six bytes. That makes the
compiler think that the output of "port%d" may be truncated.
That can't actually happen as the interface can support
maximum of eight ports. To make the compiler happy just
increase the buffer to where the warning goes away.

Pull KVM x86 fixes from Paolo Bonzini:
- Disable AVIC on SNP-enabled systems that don't allow writes to the

host when running VMs of any flavor.
- Fix a WARN in the hypercall completion path due to KVM trying to
determine if a guest with protected register state is in 64-bit mode
(KVM's ABI is to assume such guests only make hypercalls in 64-bit
mode).
- Allow the guest to write to supported bits in MSR_AMD64_DE_CFG to fix
a regression with Windows guests, and because KVM's read-only
behavior appears to be entirely made up.
- Treat TDP MMU faults as spurious if the faulting access is allowed
given the existing SPTE. This fixes a benign WARN (other than the
WARN itself) due to unexpectedly replacing a writable SPTE with a
read-only SPTE.
- Emit a warning when KVM is configured with ignore_msrs=1 and also to
hide the MSRs that the guest is looking for from the kernel logs.
ignore_msrs can trick guests into assuming that certain processor
features are present, and this in turn leads to bogus bug reports.

When running KVM with ignore_msrs=1 and report_ignored_msrs=0, the user has
no clue that that the guest is being lied to. This may cause bug reports
such as https://gitlab.com/qemu-project/qemu/-/issues/2571, where enabling
a CPUID bit in QEMU caused Linux guests to try reading MSR_CU_DEF_ERR; and
being lied about the existence of MSR_CU_DEF_ERR caused the guest to assume
other things about the local APIC which were not true:

My tests run an allyesconfig build and it failed with the following errors:
LD [M] samples/kfifo/dma-example.ko
ld.lld: error: undefined symbol: nec7210_board_reset
ld.lld: error: undefined symbol: nec7210_read
ld.lld: error: undefined symbol: nec7210_write
It appears that some modules call the function nec7210_board_reset()
that is defined in nec7210.c. In an allyesconfig build, these other
modules are built in. But the file that holds nec7210_board_reset()
has:
obj-m += nec7210.o
Where that "-m" means it only gets built as a module. With the other
modules built in, they have no access to nec7210_board_reset() and the build
fails.
This isn't the only function. After fixing that one, I hit another:
ld.lld: error: undefined symbol: push_gpib_event
ld.lld: error: undefined symbol: gpib_match_device_path
Where push_gpib_event() was also used outside of the file it was defined
in, and that file too only was built as a module.
Since the directory that nec7210.c is only traversed when
CONFIG_GPIB_NEC7210 is set, and the directory with gpib_common.c is only
traversed when CONFIG_GPIB_COMMON is set, use those configs as the
option to build those modules. When it is an allyesconfig, then they
will both be built in and their functions will be available to the other
modules that are also built in.

Pull PCI fixes from Krzysztof Wilczyński:
"Two small patches that are important for fixing boot time hang on
Intel JHL7540 'Titan Ridge' platforms equipped with a Thunderbolt
controller.
The boot time issue manifests itself when a PCI Express bandwidth
control is unnecessarily enabled on the Thunderbolt controller
downstream ports, which only supports a link speed of 2.5 GT/s in
accordance with USB4 v2 specification (p. 671, sec. 11.2.1, "PCIe
Physical Layer Logical Sub-block").
As such, there is no need to enable bandwidth control on such
downstream port links, which also works around the issue.
Both patches were tested by the original reporter on the hardware on
which the failure origin golly manifested itself. Both fixes were
proven to resolve the reported boot hang issue, and both patches have
been in linux-next this week with no reported problems"

Since commit 13b25489b6f8 ("kbuild: change working directory to external
module directory with M="), module paths are always relative to the top
of the external module tree.
The module paths recorded in Module.symvers are no longer globally unique
when they are passed via KBUILD_EXTRA_SYMBOLS for building other external
modules, which may result in false-positive "exported twice" errors.
Such errors should not occur because external modules should be able to
override in-tree modules.
To address this, record the dump file path in struct module and check it
when searching for a module.

Stop installing Debian maintainer scripts when building a
user-mode-linux Debian package.
Debian maintainer scripts are used for e.g. requesting rebuilds of
initrd, rebuilding DKMS modules and updating of grub configuration. As
all of this is not relevant for UML but also may lead to failures while
processing the kernel hooks, do no more install maintainer scripts for
the UML package.

"include/asm-<arch>" was replaced by "arch/<arch>/include/asm" a long

"#include <asm/*>", so there is no longer a need to rewrite paths.

skb_network_offset() and skb_transport_offset() can be negative when
they are called after we pull the transport header, for example, when
we use eBPF sockmap at the point of ->sk_data_ready().
__bpf_skb_min_len() uses an unsigned int to get these offsets, this
leads to a very large number which then causes bpf_skb_change_tail()
failed unexpectedly.
Fix this by using a signed int to get these offsets and ensure the
minimum is at least zero.
