Fix incorrect data offset read in the pd692x0_pi_get_pw_limit callback.
The issue was previously unnoticed as it was only used by the regulator
API and not thoroughly tested, since the PSE is mainly controlled via
ethtool.
The function became actively used by ethtool after commit 3e9dbfec4998
("net: pse-pd: Split ethtool_get_status into multiple callbacks"),
which led to the discovery of this issue.
Fix it by using the correct data offset.

Before this patch the NETDEV_XDP_ACT_NDO_XMIT XDP feature flag is set by
default as part of driver initialization, and is never cleared. However,
this flag differs from others in that it is used as an indicator for
whether the driver is ready to perform the ndo_xdp_xmit operation as
part of an XDP_REDIRECT. Kernel helpers
xdp_features_(set|clear)_redirect_target exist to convey this meaning.
This patch ensures that the netdev is only reported as a redirect target
when XDP queues exist to forward traffic.

All other(hwsp, hwctx and vmas) binaries follow this format:

The error one is just in case by some reason it was not able to

iBoot on at least some firmwares/machines leaves ANS2 running, requiring
a wake command instead of a CPU boot (and if we reset ANS2 in that
state, everything breaks).
Only stop the CPU if RTKit was running, and only do the reset dance if
the CPU is stopped.
Normal shutdown handoff:
- RTKit not yet running
- CPU detected not running
- Reset
- CPU powerup
- RTKit boot wait
ANS2 left running/idle:
- RTKit not yet running
- CPU detected running
- RTKit wake message
Sleep/resume cycle:
- RTKit shutdown
- CPU stopped
- (sleep here)
- CPU detected not running
- Reset
- CPU powerup
- RTKit boot wait
Shutdown or device removal:
- RTKit shutdown
- CPU stopped
Therefore, the CPU running bit serves as a consistent flag of whether
the coprocessor is fully stopped or just idle.

nvme_tcp_init_connection() attempts to receive an ICResp PDU but only
checks that the return value from recvmsg() is non-negative. If the
sender closes the TCP connection or sends fewer than 128 bytes, this
check will pass even though the full PDU wasn't received.
Ensure the full ICResp PDU is received by checking that recvmsg()
returns the expected 128 bytes.
Additionally set the MSG_WAITALL flag for recvmsg(), as a sender could
split the ICResp over multiple TCP frames. Without MSG_WAITALL,
recvmsg() could return prematurely with only part of the PDU.

The delayed work item function nvmet_pci_epf_poll_sqs_work() polls all
submission queues and keeps running in a loop as long as commands are

The solution for this is simply to explicitly allow rescheduling using
cond_resched(). However, since doing so for every loop of
nvmet_pci_epf_poll_sqs_work() significantly degrades performance
(for 4K random reads using 4 I/O queues, the maximum IOPS goes down from
137 KIOPS to 110 KIOPS), call cond_resched() every second to avoid the
RCU stalls.

The function nvmet_pci_epf_poll_cc_work() will do nothing if there are
no changes to the controller configuration (CC) register. However, even
for such case, this function still calls nvmet_update_cc() and uselessly
writes the CSTS register. Avoid this by simply rescheduling the poll_cc
work if the CC register has not changed.
Also reschedule the poll_cc work if the function
nvmet_pci_epf_enable_ctrl() fails to allow the host the chance to try
again enabling the controller.
While at it, since there is no point in trying to handle the CC register
as quickly as possible, change the poll_cc work scheduling interval to
10 ms (from 5ms), to avoid excessive read accesses to that register.

The function nvmet_pci_epf_poll_cc_work() sets the NVME_CSTS_RDY bit of
the controller status register (CSTS) when nvmet_pci_epf_enable_ctrl()
returns success. However, since this function can be called several
times (e.g. if the host reboots), instead of setting the bit in
ctrl->csts, initialize this field to only have NVME_CSTS_RDY set.
Conversely, if nvmet_pci_epf_enable_ctrl() fails, make sure to clear all
bits from ctrl->csts.
To simplify nvmet_pci_epf_poll_cc_work(), initialize ctrl->csts to
NVME_CSTS_RDY directly inside nvmet_pci_epf_enable_ctrl() and clear this
field in that function as well in case of a failure. To be consistent,
move clearing the NVME_CSTS_RDY bit from ctrl->csts when the controller
is being disabled from nvmet_pci_epf_poll_cc_work() into
nvmet_pci_epf_disable_ctrl().

In order for two Acer FA100 SSDs to work in one PC (in the case of
myself, a Lenovo Legion T5 28IMB05), and not show one drive and not
the other, and sometimes mix up what drive shows up (randomly), these
two lines of code need to be added, and then both of the SSDs will
show up and not conflict when booting off of one of them. If you boot
up your computer with both SSDs installed without this patch, you may
also randomly get into a kernel panic (if the initrd is not set up) or
stuck in the initrd "/init" process, it is set up, however, if you do
apply this patch, there should not be problems with booting or seeing
both contents of the drive. Tested with the btrfs filesystem with a
RAID configuration of having the root drive '/' combined to make two
256GB Acer FA100 SSDs become 512GB in total storage.

namely: setting and getting values for GPIO descriptor arrays with

This patch does two things: first it makes struct gpio_array store the

Previously, after successfully flushing the xmit buffer to VIOS,
the tx_bytes stat was incremented by the length of the skb.
It is invalid to access the skb memory after sending the buffer to
the VIOS because, at any point after sending, the VIOS can trigger
an interrupt to free this memory. A race between reading skb->len
and freeing the skb is possible (especially during LPM) and will
result in use-after-free:

According to device_release() in /drivers/base/core.c,
a device without a release function is a broken device
and must be fixed.
The current code directly frees the device after calling device_add()
without waiting for other kernel parts to release their references.
Thus, a reference could still be held to a struct device,
e.g., by sysfs, leading to potential use-after-free
issues if a proper release function is not set.

The jcore-aic irqchip does not have separate interrupt numbers reserved for
cpu-local vs global interrupts. Therefore the device drivers need to
request the given interrupt as per CPU interrupt.
69a9dcbd2d65 ("clocksource/drivers/jcore: Use request_percpu_irq()")
converted the clocksource driver over to request_percpu_irq(), but failed
to do add all the required changes, resulting in a failure to register PIT
interrupts.
Fix this by:
1) Explicitly mark the interrupt via irq_set_percpu_devid() in
jcore_pit_init().
2) Enable and disable the per CPU interrupt in the CPU hotplug callbacks.
3) Pass the correct per-cpu cookie to the irq handler by using
handle_percpu_devid_irq() instead of handle_percpu_irq() in
handle_jcore_irq().

Christoph reports that their rk3399 system dies since commit 773c05f417fa1
("irqchip/gic-v3: Work around insecure GIC integrations").
It appears that some rk3399 have secure payloads, and that the firmware
sets SCR_EL3.FIQ==1. Obivously, disabling security in that configuration
leads to even more problems.
Revisit the workaround by:
- making it rk3399 specific
- checking whether Group-0 is available, which is a good proxy
for SCR_EL3.FIQ being 0
- either apply the workaround if Group-0 is available, or disable
pseudo-NMIs if not
Note that this doesn't mean that the secure side is able to receive
interrupts, as all interrupts are made non-secure anyway.
Clearly, nobody ever tested secure interrupts on this platform.

Any active plane needs to have its crtc included in the atomic
state. For planes enabled via uapi that is all handler in the core.
But when we use a plane for joiner the uapi code things the plane
is disabled and therefore doesn't have a crtc. So we need to pull
those in by hand. We do it first thing in
intel_joiner_add_affected_crtcs() so that any newly added crtc will
subsequently pull in all of its joined crtcs as well.
The symptoms from failing to do this are:
- duct tape in the form of commit 1d5b09f8daf8 ("drm/i915: Fix NULL
ptr deref by checking new_crtc_state")
- the plane's hw state will get overwritten by the disabled
uapi state if it can't find the uapi counterpart plane in
the atomic state from where it should copy the correct state

Having an DRM_MODE_CONNECTOR_Unknown connector type is considered bad, and
drm_panel_bridge_add_typed() and derivatives are deprecated for this.
drm_panel_init() won't prevent initializing a panel with a
DRM_MODE_CONNECTOR_Unknown connector type. Luckily there are no in-tree
users doing it, so take this as an opportinuty to document a valid
connector type must be passed.
Returning an error if this rule is violated is not possible because
drm_panel_init() is a void function. Add at least a warning to make any
violations noticeable, especially to non-upstream drivers.

Add locking to `vf610_gpio_direction_input|output()` functions. Without
this locking, a race condition exists between concurrent calls to these
functions, potentially leading to incorrect GPIO direction settings.
To verify the correctness of this fix, a `trylock` patch was applied,
where after a couple of reboots the race was confirmed. I.e., one user
had to wait before acquiring the lock. With this patch the race has not
been encountered. It's worth mentioning that any type of debugging
(printing, tracing, etc.) would "resolve"/hide the issue.

this, and it passes all build tests from 0-day and linux-next, so all
should be good"

Pull serial driver fixes from Greg KH:
"Here are some small serial driver fixes for some reported problems.
Nothing major, just:
- sc16is7xx irq check fix
- 8250 fifo underflow fix
- serial_port and 8250 iotype fixes
Most of these have been in linux-next already, and all have passed
0-day testing"

Pull kvm fixes from Paolo Bonzini:
"ARM:
- Large set of fixes for vector handling, especially in the
interactions between host and guest state.
This fixes a number of bugs affecting actual deployments, and
greatly simplifies the FP/SIMD/SVE handling. Thanks to Mark Rutland
for dealing with this thankless task.
- Fix an ugly race between vcpu and vgic creation/init, resulting in
unexpected behaviours
- Fix use of kernel VAs at EL2 when emulating timers with nVHE
- Small set of pKVM improvements and cleanups
x86:
- Fix broken SNP support with KVM module built-in, ensuring the PSP
module is initialized before KVM even when the module
infrastructure cannot be used to order initcalls
- Reject Hyper-V SEND_IPI hypercalls if the local APIC isn't being
emulated by KVM to fix a NULL pointer dereference
- Enter guest mode (L2) from KVM's perspective before initializing
the vCPU's nested NPT MMU so that the MMU is properly tagged for
L2, not L1
- Load the guest's DR6 outside of the innermost .vcpu_run() loop, as
the guest's value may be stale if a VM-Exit is handled in the
fastpath"
