Pull x86 cpu updates from Ingo Molnar:
- Rework the x86 CPU vendor/family/model code: introduce the 'VFM'
value that is an 8+8+8 bit concatenation of the vendor/family/model
value, and add macros that work on VFM values. This simplifies the
addition of new Intel models & families, and simplifies existing
enumeration & quirk code.
- Add support for the AMD 0x80000026 leaf, to better parse topology
information
- Optimize the NUMA allocation layout of more per-CPU data structures
- Improve the workaround for AMD erratum 1386
- Clear TME from /proc/cpuinfo as well, when disabled by the firmware
- Improve x86 self-tests
- Extend the mce_record tracepoint with the ::ppin and ::microcode fields
- Implement recovery for MCE errors in TDX/SEAM non-root mode
- Misc cleanups and fixes

Move the EST structure to struct stmmac_priv, because the
EST configs don't look like platform config, but EST is
enabled in runtime with the settings retrieved for the TC
TAPRIO feature also in runtime. So it's better to have the
EST-data preserved in the driver private data instead of
the platform data storage.

Reinitialize the whole EST structure would also reset the mutex
lock which is embedded in the EST structure, and then trigger
the following warning. To address this, move the lock to struct
stmmac_priv. We also need to reacquire the mutex lock when doing
this initialization.

====================
mptcp: small improvements, fix and clean-ups
This series contain mostly unrelated patches:
- The two first patches can be seen as "fixes". They are part of this
series for -next because it looks like the last batch of fixes for
v6.9 has already been sent. These fixes are not urgent, so they can
wait if an unlikely v6.9-rc8 is published. About the two patches:
- Patch 1 fixes getsockopt(SO_KEEPALIVE) support on MPTCP sockets
- Patch 2 makes sure the full TCP keep-alive feature is supported,
not just SO_KEEPALIVE.
- Patch 3 is a small optimisation when getsockopt(MPTCP_INFO) is used
without buffer, just to check if MPTCP is still being used: no
fallback to TCP.
- Patch 4 adds net.mptcp.available_schedulers sysctl knob to list packet
schedulers, similar to net.ipv4.tcp_available_congestion_control.
- Patch 5 and 6 fix CheckPatch warnings: "prefer strscpy over strcpy"
and "else is not generally useful after a break or return".
- Patch 7 and 8 remove and add header includes to avoid unused ones, and
add missing ones to be self-contained.

strcpy() performs no bounds checking on the destination buffer. This
could result in linear overflows beyond the end of the buffer, leading
to all kinds of misbehaviors. The safe replacement is strscpy() [1].
This is in preparation of a possible future step where all strcpy() uses
will be removed in favour of strscpy() [2].
This fixes CheckPatch warnings:

Up to recently, it has been recommended to use getsockopt(MPTCP_INFO) to
check if a fallback to TCP happened, or if the client requested to use
MPTCP.
In this case, the userspace app is only interested by the returned value
of the getsocktop() call, and can then give 0 for the option length, and
NULL for the buffer address. An easy optimisation is then to stop early,
and avoid filling a local buffer -- which now requires two different
locks -- if it is not needed.

SO_KEEPALIVE support has been added a while ago, as part of a series
"adding SOL_SOCKET" support. To have a full control of this keep-alive
feature, it is important to also support TCP_KEEP* socket options at the
SOL_TCP level.
Supporting them on the setsockopt() part is easy, it is just a matter of
remembering each value in the MPTCP sock structure, and calling
tcp_sock_set_keep*() helpers on each subflow. If the value is not
modified (0), calling these helpers will not do anything. For the
getsockopt() part, the corresponding value from the MPTCP sock structure
or the default one is simply returned. All of this is very similar to
other TCP_* socket options supported by MPTCP.
It looks important for kernels supporting SO_KEEPALIVE, to also support
TCP_KEEP* options as well: some apps seem to (wrongly) consider that if
the former is supported, the latter ones will be supported as well. But
also, not having this simple and isolated change is preventing MPTCP
support in some apps, and libraries like GoLang [1]. This is why this
patch is seen as a fix.

SO_KEEPALIVE support has to be set on each subflow: on each TCP socket,
where sk_prot->keepalive is defined. Technically, nothing has to be done
on the MPTCP socket. That's why mptcp_sol_socket_sync_intval() was
called instead of mptcp_sol_socket_intval().
Except that when nothing is done on the MPTCP socket, the
getsockopt(SO_KEEPALIVE), handled in net/core/sock.c:sk_getsockopt(),
will not know if SO_KEEPALIVE has been set on the different subflows or
not.
The fix is simple: simply call mptcp_sol_socket_intval() which will end
up calling net/core/sock.c:sk_setsockopt() where the SOCK_KEEPOPEN flag
will be set, the one used in sk_getsockopt().
So now, getsockopt(SO_KEEPALIVE) on an MPTCP socket will return the same
value as the one previously set with setsockopt(SO_KEEPALIVE).

The "struct prestera_msg_vtcam_rule_add_req" uses a dynamically sized
set of trailing elements. Specifically, it uses an array of structures
of type "prestera_msg_acl_action actions_msg".
The "struct prestera_msg_flood_domain_ports_set_req" also uses a
dynamically sized set of trailing elements. Specifically, it uses an
array of structures of type "prestera_msg_acl_action actions_msg".
So, use the preferred way in the kernel declaring flexible arrays [1].
At the same time, prepare for the coming implementation by GCC and Clang
of the __counted_by attribute. Flexible array members annotated with
__counted_by can have their accesses bounds-checked at run-time via
CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for
strcpy/memcpy-family functions). In this case, it is important to note
that the attribute used is specifically __counted_by_le since the
counters are of type __le32.
The logic does not need to change since the counters for the flexible
arrays are asigned before any access to the arrays.
The order in which the structure prestera_msg_vtcam_rule_add_req and the
structure prestera_msg_flood_domain_ports_set_req are defined must be
changed to avoid incomplete type errors.
Also, avoid the open-coded arithmetic in memory allocator functions [2]
using the "struct_size" macro.
Moreover, the new structure members also allow us to avoid the open-
coded arithmetic on pointers. So, take advantage of this refactoring
accordingly.
This code was detected with the help of Coccinelle, and audited and
modified manually.

There is a deadlock issue found in sungem driver, please refer to the
commit ac0a230f719b ("eth: sungem: remove .ndo_poll_controller to avoid
deadlocks"). The root cause of the issue is that netpoll is in atomic
context and disable_irq() is called by .ndo_poll_controller interface
of sungem driver, however, disable_irq() might sleep. After analyzing
the implementation of fec_poll_controller(), the fec driver should have
the same issue. Due to the fec driver uses NAPI for TX completions, the
.ndo_poll_controller is unnecessary to be implemented in the fec driver,
so fec_poll_controller() can be safely removed.

We're going to send an RST due to invalid syn packet which is already
checked whether 1) it is in sequence, 2) it is a retransmitted skb.
As RFC 793 says, if the state of socket is not CLOSED/LISTEN/SYN-SENT,
then we should send an RST when receiving bad syn packet:
"fourth, check the SYN bit,...If the SYN is in the window it is an
error, send a reset"

====================
net: stmmac: Add support for RZN1 GMAC devices
This is version seven of my series that adds support for a Gigabit Ethernet
controller featured in the Renesas r9a06g032 SoC, of the RZ/N1 family. This
GMAC device is based on a Synopsys IP and is compatible with the stmmac driver.
My former colleague Clément Léger originally sent a series for this driver,
but an issue in bringing up the PCS clock had blocked the upstreaming
process. This issue has since been resolved by the following series:
https://lore.kernel.org/all/20240326-rxc_bugfix-v6-0-24a74e5c761f@bootlin.com/
This series consists of a devicetree binding describing the RZN1 GMAC
controller IP, a node for the GMAC1 device in the r9a06g032 SoC device
tree, and the GMAC driver itself which is a glue layer in stmmac.
There are also two patches by Russell that improve pcs initialization handling
in stmmac.

Use the newly introduced pcs_init() and pcs_exit() operations to
create and destroy the PCS instance at a more appropriate moment during
the driver lifecycle, thereby avoiding publishing a network device to
userspace that has not yet finished its PCS initialisation.
There are other similar issues with this driver which remain
unaddressed, but these are out of scope for this patch.

A pcs_init() callback will be introduced to stmmac in a future patch. This
new function will be called during the hardware initialization phase.
Instead of separately initializing XPCS and PCS components, let's group all
PCS-related hardware initialization logic in the current
stmmac_xpcs_setup() function.
Rename stmmac_xpcs_setup() to stmmac_pcs_setup() and move the conditional
call to stmmac_xpcs_setup() inside the function itself.

Currently the XPCS handler destruction is performed in the
stmmac_mdio_unregister() method. It doesn't look good because the handler
isn't originally created in the corresponding protagonist
stmmac_mdio_unregister(), but in the stmmac_xpcs_setup() function. In
order to have more coherent MDIO and XPCS setup/cleanup procedures,
let's move the DW XPCS destruction to the dedicated stmmac_pcs_clean()
method.
This method will also be used to cleanup PCS hardware using the
pcs_exit() callback that will be introduced to stmmac in a subsequent
patch.

Use flow_rule_match_has_control_flags() to check for control flags,
such as can be set through `tc flower ... ip_flags frag`.
In case any control flags are masked, flow_rule_match_has_control_flags()
sets a NL extended error message, and we return -EOPNOTSUPP.

====================
virtio_net: rx enable premapped mode by default
Actually, for the virtio drivers, we can enable premapped mode whatever
the value of use_dma_api. Because we provide the virtio dma apis.
So the driver can enable premapped mode unconditionally.
This patch set makes the big mode of virtio-net to support premapped mode.
And enable premapped mode for rx by default.
Based on the following points, we do not use page pool to manage these
pages:
1. virtio-net uses the DMA APIs wrapped by virtio core. Therefore,
we can only prevent the page pool from performing DMA operations, and
let the driver perform DMA operations on the allocated pages.
2. But when the page pool releases the page, we have no chance to
execute dma unmap.
3. A solution to #2 is to execute dma unmap every time before putting
the page back to the page pool. (This is actually a waste, we don't
execute unmap so frequently.)
4. But there is another problem, we still need to use page.dma_addr to
save the dma address. Using page.dma_addr while using page pool is
unsafe behavior.
5. And we need space the chain the pages submitted once to virtio core.
More:

Why we do not use the page space to store the dma?
