Recently, the spinlock implementation grew a static key optimization,
but the jump_label.h header include was left out, leading to build
errors:
linux/arch/powerpc/include/asm/spinlock.h:44:7: error: implicit declaration of function ‘static_branch_unlikely’
44 | if (!static_branch_unlikely(&shared_processor))
This commit adds the missing header.
mpe: The build break is only seen with CONFIG_JUMP_LABEL=n.

ASUS reported that there's an bass speaker in addition to internal
speaker and it uses DAC 0x02. It was not enabled in the commit
436e25505f34 ("ALSA: hda/realtek - Enable internal speaker of ASUS
UX431FLC") which only enables the amplifier and the front speaker.
This commit enables the bass speaker on top of the aforementioned

Ido Schimmel says:
====================
mlxsw: Couple of fixes
This patch set contains two fixes for mlxsw. Please consider both for
stable.
Patch #1 from Amit fixes a wrong check during MAC validation when
creating router interfaces (RIFs). Given a particular order of
configuration this can result in the driver refusing to create new RIFs.
Patch #2 fixes a wrong trap configuration in which VRRP packets and
routing exceptions were policed by the same policer towards the CPU. In
certain situations this can prevent VRRP packets from reaching the CPU.
====================

Currently, VRRP packets and packets that hit exceptions during routing
(e.g., MTU error) are policed using the same policer towards the CPU.
This means, for example, that misconfiguration of the MTU on a routed
interface can prevent VRRP packets from reaching the CPU, which in turn
can cause the VRRP daemon to assume it is the Master router.
Fix this by using a dedicated policer for VRRP packets.

When a router interface (RIF) is created the MAC address of the backing
netdev is verified to have the same MSBs as existing RIFs. This is
required in order to avoid changing existing RIF MAC addresses that all
share the same MSBs.
Loopback RIFs are special in this regard as they do not have a MAC
address, given they are only used to loop packets from the overlay to
the underlay.
Without this change, an error is returned when trying to create a RIF
after the creation of a GRE tunnel that is represented by a loopback
RIF. 'rif->dev->dev_addr' points to the GRE device's local IP, which
does not share the same MSBs as physical interfaces. Adding an IP
address to any physical interface results in:
Error: mlxsw_spectrum: All router interface MAC addresses must have the
same prefix.
Fix this by skipping loopback RIFs during MAC validation.

Jia-Ju Bai reported a possible sleep-in-atomic scenario in the ice1724
driver with Infrasonic Quartet support code: namely, ice->set_rate
callback gets called inside ice->reg_lock spinlock, while the callback
in quartet.c holds ice->gpio_mutex.
This patch fixes the invalid call: it simply moves the calls of
ice->set_rate and ice->set_mclk callbacks outside the spinlock.

Some filesystem, such as vfat, may send bio which crosses device boundary,
and the worse thing is that the IO request starting within device boundaries
can contain more than one segment past EOD.
Commit dce30ca9e3b6 ("fs: fix guard_bio_eod to check for real EOD errors")
tries to fix this issue by returning -EIO for this situation. However,
this way lets fs user code lose chance to handle -EIO, then sync_inodes_sb()
may hang for ever.
Also the current truncating on last segment is dangerous by updating the
last bvec, given bvec table becomes not immutable any more, and fs bio
users may not retrieve the truncated pages via bio_for_each_segment_all() in
its .end_io callback.
Fixes this issue by supporting multi-segment truncating. And the
approach is simpler:
- just update bio size since block layer can make correct bvec with
the updated bio size. Then bvec table becomes really immutable.
- zero all truncated segments for read bio

When support for !MMU was added, the declaration of
__asm_copy_to_user() & __asm_copy_from_user() were #ifdefed
out hence their EXPORT_SYMBOL() give an error message like:
.../riscv_ksyms.c:13:15: error: '__asm_copy_to_user' undeclared here
.../riscv_ksyms.c:14:15: error: '__asm_copy_from_user' undeclared here
Since these symbols are not defined with !MMU it's wrong to export them.
Same for __clear_user() (even though this one is also declared in
include/asm-generic/uaccess.h and thus doesn't give an error message).
Fix this by doing the EXPORT_SYMBOL() directly where these symbols
are defined: inside lib/uaccess.S itself.

GXBB and newer SoCs use the fixed FCLK_DIV2 (1GHz) clock as input for
the m250_sel clock. Meson8b and Meson8m2 use MPLL2 instead, whose rate
can be adjusted at runtime.
So far we have been running MPLL2 with ~250MHz (and the internal
m250_div with value 1), which worked enough that we could transfer data
with an TX delay of 4ns. Unfortunately there is high packet loss with
an RGMII PHY when transferring data (receiving data works fine though).
Odroid-C1's u-boot is running with a TX delay of only 2ns as well as
the internal m250_div set to 2 - no lost (TX) packets can be observed
with that setting in u-boot.
Manual testing has shown that the TX packet loss goes away when using
the following settings in Linux (the vendor kernel uses the same
settings):
- MPLL2 clock set to ~500MHz
- m250_div set to 2
- TX delay set to 2ns on the MAC side
Update the m250_div divider settings to only accept dividers greater or
equal 2 to fix the TX delay generated by the MAC.

There's no skb_pull performed when a mirred action is set at egress of a
mac device, with a target device/action that expects skb->data to point
at the network header.
As a result, either the target device is errornously given an skb with
data pointing to the mac (egress case), or the net stack receives the
skb with data pointing to the mac (ingress case).
E.g:
# tc qdisc add dev eth9 root handle 1: prio
# tc filter add dev eth9 parent 1: prio 9 protocol ip handle 9 basic \
action mirred egress redirect dev tun0
(tun0 is a tun device. result: tun0 errornously gets the eth header
instead of the iph)
Revise the push/pull logic of tcf_mirred_act() to not rely on the
skb_at_tc_ingress() vs tcf_mirred_act_wants_ingress() comparison, as it
does not cover all "pull" cases.
Instead, calculate whether the required action on the target device
requires the data to point at the network header, and compare this to
whether skb->data points to network header - and make the push/pull
adjustments as necessary.

The burning process requires to perform internal allocations of large
chunks of memory. This memory doesn't need to be contiguous and can be
safely allocated by vzalloc() instead of kzalloc(). This patch changes
such allocation to avoid possible out-of-memory failure.

The downstream implementation of ahci_brcm.c did contain clock
management recovery, but until recently, did that outside of the
libahci_platform helpers and this was unintentionally stripped out while
forward porting the patch upstream.
Add the missing clock management during recovery and sleep for 10
milliseconds per the design team recommendations to ensure the SATA PHY
controller and AFE have been fully quiesced.

Set AHCI_HFLAG_DELAY_ENGINE for the BCM7425 AHCI controller thus making
it conforming to the 'strict' AHCI implementation which this controller
is based on.
This solves long link establishment with specific hard drives (e.g.:
Seagate ST1000VM002-9ZL1 SC12) that would otherwise have to complete the
error recovery handling before finally establishing a succesful SATA
link at the desired speed.
We re-order the hpriv->flags assignment to also remove the NONCQ quirk
since we can set the flag directly.

The AHCI resources management within ahci_brcm.c is a little
convoluted, largely because it historically had a dedicated clock that
was managed within this file in the downstream tree. Once brough
upstream though, the clock was left to be managed by libahci_platform.c
which is entirely appropriate.
This patch series ensures that the AHCI resources are fetched and
enabled before any register access is done, thus avoiding bus errors on
platforms which clock gate the controller by default.
As a result we need to re-arrange the suspend() and resume() functions
in order to avoid accessing registers after the clocks have been turned
off respectively before the clocks have been turned on. Finally, we can
refactor brcm_ahci_get_portmask() in order to fetch the number of ports
from hpriv->mmio which is now accessible without jumping through hoops
like we used to do.
The commit pointed in the Fixes tag is both old and new enough not to
require major headaches for backporting of this patch.

This reverts commit 6bb86fefa086faba7b60bb452300b76a47cde1a5
("libahci_platform: Staticize ahci_platform_<en/dis>able_phys()") we are
going to need ahci_platform_{enable,disable}_phys() in a subsequent
commit for ahci_brcm.c in order to properly control the PHY
initialization order.
Also make sure the function prototypes are declared in
include/linux/ahci_platform.h as a result.

====================
hsr: fix several bugs in hsr module
1. The first patch fixes debugfs warning when it's opened when hsr module
is being removed. debugfs file is opened, it tries to hold .owner module,
but it would print warning messages if it couldn't hold .owner module.
In order to avoid the warning message, this patch makes hsr module does
not set .owner. Unsetting .owner is safe because these are protected by
inode_lock().
2. The second patch fixes wrong error handling of hsr_dev_finalize()
a) hsr_dev_finalize() calls debugfs_create_{dir/file} to create debugfs.
it checks NULL pointer but debugfs don't return NULL so it's wrong code.
b) hsr_dev_finalize() calls register_netdevice(). so if it fails after
register_netdevice(), it should call unregister_netdevice().
But it doesn't.
c) debugfs doesn't affect any actual logic of hsr module.
So, the failure of creating of debugfs could be ignored.
3. The third patch adds hsr root debugfs directory.
When hsr interface is created, it creates debugfs directory in
/sys/kernel/debug/<interface name>.
It's a little bit faulty path because if an interface is the same with
another directory name in the same path, it will fail. If hsr root
directory is existing, the possibility of failure of creating debugfs
file will be reduced.
4. The fourth patch adds debugfs rename routine.
debugfs directory name is the same with hsr interface name.
So hsr interface name is changed, debugfs directory name should be
changed too.
5. The fifth patch fixes a race condition in node list add and del.
hsr nodes are protected by RCU and there is no write side lock.
But node insertions and deletions could be being operated concurrently.
So write side locking is needed.
6. The Sixth patch resets network header
Tap routine is enabled, below message will be printed.
[ 175.852292][ C3] protocol 88fb is buggy, dev veth0
hsr module doesn't set network header for supervision frame.
But tap routine validates network header.
If network header wasn't set, it resets and warns about it.

The supervision frame is L2 frame.
When supervision frame is created, hsr module doesn't set network header.
If tap routine is enabled, dev_queue_xmit_nit() is called and it checks
network_header. If network_header pointer wasn't set(or invalid),
it resets network_header and warns.
In order to avoid unnecessary warning message, resetting network_header
is needed.
Test commands:
ip netns add nst
ip link add veth0 type veth peer name veth1
ip link add veth2 type veth peer name veth3
ip link set veth1 netns nst
ip link set veth3 netns nst
ip link set veth0 up
ip link set veth2 up
ip link add hsr0 type hsr slave1 veth0 slave2 veth2
ip a a 192.168.100.1/24 dev hsr0
ip link set hsr0 up
ip netns exec nst ip link set veth1 up
ip netns exec nst ip link set veth3 up
ip netns exec nst ip link add hsr1 type hsr slave1 veth1 slave2 veth3
ip netns exec nst ip a a 192.168.100.2/24 dev hsr1
ip netns exec nst ip link set hsr1 up
tcpdump -nei veth0
Splat looks like:
