Allocate memory for the data when it's used. Ideally the struct could
be on the stack, but we can't DMA stack memory. With this change only
the header and status memory are shared between commands, which will
allow using a tighter lock than RTNL.

Currently, the MT7530 DSA subdriver configures the MT7530 switch to provide
direct access to switch PHYs, meaning, the switch PHYs listen on the MDIO
bus the switch listens on. The PHY muxing feature makes use of this.
This is problematic as the PHY may be attached before the switch is
initialised, in which case, the PHY will fail to be attached.
Since commit 91374ba537bd ("net: dsa: mt7530: support OF-based registration
of switch MDIO bus"), we can describe the switch PHYs on the MDIO bus of
the switch on the device tree. Extend the check to detect PHY muxing when
the PHY is defined on the MDIO bus of the switch on the device tree.
When the PHY is described this way, the switch will be initialised first,
then the switch MDIO bus will be registered. Only after these steps, the
PHY will be attached.

qede_parse_actions() can currently fail with:

Commit 319a1d19471e ("flow_offload: check for

assumption that it could only fail with -EINVAL,
by changing it to return -EOPNOTSUPP, when hardware
stats are requested.
However AFAICT it's not possible to trigger
qede_parse_actions() to return -EOPNOTSUPP, when
called from qede_flow_spec_to_rule(), as hardware
stats can't be requested by ethtool_rx_flow_rule_create().

RISC-V SoC Kconfig Updates for v6.10
A few different bits of SoC-related Kconfig work. The first part of
this is shared with the DT updates - the modification of all SOC_CANAAN
users to SOC_CANAAN_K210 to split the existing m-mode nommu k210 away
from the k230 that is able to be used in a "common" kernel.
The other thing here is the removal of most of the SOC_VENDOR options,
with their ARCH_VENDOR equivalents that've been waiting in the wings for
1 year+ now made visible. Due a lapse on my part when originally adding
the ARCH_VENDOR stuff, the Microchip transition isn't complete - the
_POLARFIRE was a mistake to keep as there's gonna be non-PolarFire
RISC-V stuff from Microchip soonTM.

According to GCC, the constriction of irq_name in otx2_open()
may, theoretically, be truncated.
This patch takes the approach of treating such a situation as an error
which it detects by making use of the return value of snprintf, which is
the total number of bytes, excluding the trailing '\0', that would have
been written.
Based on the approach taken to a similar problem in
commit 54b909436ede ("rtc: fix snprintf() checking in is_rtc_hctosys()")
Flagged by gcc-13 W=1 builds as:
.../otx2_pf.c:1933:58: warning: 'snprintf' output may be truncated before the last format character [-Wformat-truncation=]

- Redefining relevant structs to __le32/__be32 data types for proper cpu

However during rmmod, the flag is not cleared leading to unnecessary delays

Hi Martin, James & Alim,
This series adds support to the ufs-exynos driver for Tensor gs101
found in Pixel 6. It was send previously in [1] and [2] but included
the other clock, phy and DTS parts. This series has been split into
just the ufs-exynos part to hopefully make things easier.
With this series, plus the phy, clock and dts changes UFS is
functional upstream for Pixel 6. The SKhynix HN8T05BZGKX015 can be
enumerated, partitions mounted etc.
The series is split into some prepatory patches for ufs-exynos and a
final patch that adds the gs101 support.
Note the sysreg clock has been moved to ufs node as fine grained clock
control around the syscon sysreg register accesses doesn't result in
functional UFS.

To maintain backwards compatibility in the case a DT does not provide
an avdd-supply, we fall back to calling devm_regulator_get_enable()

will still be in sysfs).
Also add an informative error message when we failed to get the voltage
and knowing the voltage is required while we are touching this.

Currently, we allocate a count-sized kernel buffer and copy count from
userspace to that buffer. Later, we use kstrtouint on this buffer but we
don't ensure that the string is terminated inside the buffer, this can
lead to OOB read when using kstrtouint. Fix this issue by using
memdup_user_nul instead of memdup_user.

Currently, we allocate a nbytes-sized kernel buffer and copy nbytes from
userspace to that buffer. Later, we use sscanf on this buffer but we don't
ensure that the string is terminated inside the buffer, this can lead to
OOB read when using sscanf. Fix this issue by using memdup_user_nul instead
of memdup_user.

This allows to define a GTP tunnel for dual stack MS/UE with both IPv4
and IPv6 addresses while using the same TEID via two PDP context
objects.

Add new protocol field to PDP context that determines the transmit path
IP protocol to encapsulate the original packets, either IPv4 or IPv6.
Relax existing netlink attribute checks to allow to specify different
family in MS and peer attributes from the control plane.
Use build helpers to tx path to encapsulate IPv4-in-IPv6-GTP and
IPv6-in-IPv4-GTP according to the user-specified configuration.
From rx path, snoop for the inner protocol header since outer
skb->protocol might differ and use this to validate for valid PDP
context and to restore skb->protocol after decapsulation.

Add routine to attach an IPv6 route for the encapsulated packet, deal
with Path MTU and push GTP header.
This helper function will be used to deal with IPv4-in-IPv6-GTP.

Based on the idea that ip_tunnel_get_dsfield() provides the tos field
regardless the IP version, use either iph->tos or ipv6_get_dsfield().
This comes in preparation to support for IPv4-in-IPv6-GTP and
IPv6-in-IPv4-GTP.

According to TS 29.061, it is possible to see IPv6 link-local traffic in
the GTP tunnel, see 11.2.1.3.2 IPv6 Stateless Address Autoconfiguration
(IPv6 SLAAC).
Pass up these packets to the userspace daemon to handle them as control
GTP traffic.
