usb: dwc3: gadget: WARN() on bogus usb_ep_queue()
Some gadget/function drivers might want to do
improper request recycling by allocating a single
request from one particular endpoint and queueing
it to another completely unrelated endpoint.
One such case was found with f_loopback.c.
To prevent such cases from happening again, let's
WARN() so we get a loud enough failure and persuade
users to report errors.
USB gadgets composed with configfs lack suspend and resume
methods. This patch uses composite_suspend()/composite_resume()
the same way e.g. composite_setup() or composite_disconnect()
are used in a configfs-based gadget.

usb: dwc3: dwc3-omap: get rid of ->prepare()/->complete()
Enabling the core interrupts in complete is too late for
XHCI, and stops it from proper operation. The root of the
problem is due to a disagreement between dwc3-omap and XHCI
about when IRQs should be enabled.
As it turns out, ->resume's documentation states that:
"... generally the driver is expected to start working
again, responding to hardware events and software requests
(the device itself may be left in a low-power state, waiting
for a runtime resume to occur) ..."
From that we infer that IRQs must be unmasked by the end of
->resume().
Due to that, we will remove ->prepare() and ->complete() and
disable/enable interrupts in ->suspend()/->resume().

usb: gadget: composite: conditionally dequeue os_desc and setup requests
In case we unload a gadget driver while any of
os_desc_req or req are still pending, we need
to make sure to dequeue them.
By using our setup_pending and os_desc_pending
flags we achieve that in a way that doesn't
cause any regressions because we won't dequeue
a request which was already completed.
The original idea came from Li Jun's commit f2267089ea17fa97b796b1b4247e3f8957655df3
(usb: gadget: composite: dequeue cdev->req
before free it in composite_dev_cleanup) which,
unfortunately, caused two regressions (kfree()
being called before usb_ep_dequeue() and calling
usb_ep_dequeue() when the request was already
completed). That commit also didn't take care
of os_desc_req which can fall into the same
situation so we must care for that one too.
Note that in order to make code slightly easier
to read, we introduce composite_ep_queue() which
hides details about how to fiddle with our pending
flags.

that register and use it for debugging.

In order to access the shadow VMCS, we need to load it. At this point,
vmx->loaded_vmcs->vmcs and the actually loaded one start to differ. If

vmx_vcpu_load will work against the wrong vmcs. That can cause

Fix the issue by disabling preemption during the copy operation.
copy_vmcs12_to_shadow is safe from this issue as it is executed by
vmx_vcpu_run when preemption is already disabled before vmentry.
This bug is exposed by running Jailhouse within KVM on CPUs with
shadow VMCS support. Jailhouse never expects an interrupt pending

is preempted, the active VMCS happens to have the virtual interrupt

PM / Sleep: fix async suspend_late/freeze_late error handling
ACPI: Use ACPI companion to match only the first physical device
cpufreq: cpufreq-dt: disable unsupported OPPs
An unintentional sysfs filename change in commit 5136b2da770d
("PCI: convert bus code to use dev_groups"), which appeared in
v3.13, changed "enable" to "enabled", and this changes it back.
Old users of "enable" are currently broken and will be helped by
this change. Anything that started to use "enabled" after v3.13
will be broken by this change. If necessary, we can add a symlink
to make both work, but this patch doesn't do that.
A mistaken duplicate merge that added a check twice. Nothing's
broken; this just removes the unnecessary code.

x86_64, entry: Fix out of bounds read on sysenter
Rusty noticed a Really Bad Bug (tm) in my NT fix. The entry code
reads out of bounds, causing the NT fix to be unreliable. But, and
this is much, much worse, if your stack is somehow just below the
top of the direct map (or a hole), you read out of bounds and crash.
That read is deterministically above the top of the stack. I
thought I even single-stepped through this code when I wrote it to
check the offset, but I clearly screwed it up.

drivers: net: cpsw: Support ALLMULTI and fix IFF_PROMISC in switch mode
The cpsw driver did not support the IFF_ALLMULTI flag which makes dynamic
multicast routing not work. Related to this, when enabling IFF_PROMISC
in switch mode, all registered multicast addresses are flushed, resulting
in only broadcast and unicast traffic being received.
A new cpsw_ale_set_allmulti function now scans through the ALE entry
table and adds/removes the host port from the unregistered multicast
port mask of each vlan entry depending on the state of IFF_ALLMULTI.
In promiscious mode, cpsw_ale_set_allmulti is used to force reception
of all multicast traffic in addition to the unicast and broadcast traffic.
With this change dynamic multicast and promiscious mode both work in
switch mode.

while fixing a real bug.
It was correct to fix the dual_emac mode section since there 'i' is used
as an index into priv->slaves which is a 0 based array.
However the other two changes (which are only used in switch mode)
are wrong since there 'i' is actually the ALE port number, and port 0
is the host port, while port 1 and up are the slave ports.
Putting the loop condition back in the switch mode section fixes it.
A comment has been added to point out the intent clearly to avoid future
confusion. Also a comment is fixed that said the opposite of what was
actually happening.
