It has been reported that on Fairphone 2 (msm8974-based), increasing
the clock rate for some of the NoCs during boot may lead to hangs.
Let's restore the original behavior and not touch the clock rate of
any of the NoCs to fix the regression.

When sync_state support got introduced recently, by default we try to
set the NoCs to run initially at maximum rate. But as these values are
aggregated, we may end with a really big clock rate value, which is
then converted from "u64" to "long" during the clock rate rounding.
But on 32bit platforms this may result an overflow. Fix it by making
sure that the rate is within range.

Pull char/misc fixes/removals from Greg KH:
"Here's some small fixes for 5.10-rc2 and a big driver removal.
The fixes are for some reported issues in the interconnect and
coresight drivers, nothing major.
The "big" driver removal is the MIC drivers have been asked to be
removed as the hardware never shipped and Intel no longer wants to
maintain something that no one can use. This is welcomed by many as
the DMA usage of these drivers was "interesting" and the security
people were starting to question some issues that were starting to be
found in the codebase.
Note, one of the subsystems for this driver, the "VOP" code, will
probably come back in future kernel versions as it was looking to
potentially solve some PCIe virtualization issues that a number of
other vendors were wanting to solve. But as-is, this codebase didn't
work for anyone else so no actual functionality is being removed.
All of these have been in linux-next with no reported issues"

There is a regular need in the kernel to provide a way to declare having a
dynamically sized set of trailing elements in a structure. Kernel code should
always use “flexible array members”[1] for these cases. The older style of
one-element or zero-length arrays should no longer be used[2].

Refactor the code according to the use of a flexible-array member in

struct_size() helper to calculate the size for the resource allocation.

- Fixes in some drivers to make sure the correct sequence is used for

vdpa_sim generates a ramdom MAC address but it is never used by upper
layers because the VIRTIO_NET_F_MAC bit is not set in the features list.
Because of that, virtio-net always regenerates a random MAC address each
time it is loaded whereas the address should only change on vdpa_sim
load/unload.
Fix that by adding VIRTIO_NET_F_MAC in the features list of vdpa_sim.

LKP considered variable 'ret' in vhost_vdpa_setup_vq_irq() as
a unused variable, so suggest we remove it. Actually it stores
return value of irq_bypass_register_producer(), but we did not
check it, we should handle the failure case.
This commit will print a message if irq bypass register producer
fail, in this case, vqs still remain functional.

When the system goes to suspend, if the controller is at device mode with
cable connecting to host, the call stack is: cdns3_suspend->
cdns3_gadget_suspend -> cdns3_disconnect_gadget, after cdns3_disconnect_gadget
is called, it owns lock wrongly, it causes the system being deadlock after
resume due to at cdns3_device_thread_irq_handler, it tries to get the lock,
but can't get it forever.
To fix it, we delete the unlock-lock operations at cdns3_disconnect_gadget,
and do it at the caller.

Patch fixes issue caused setting On-chip memory overflow bit in usb_sts
register. The issue occurred because EP_CFG register was set twice
before USB_STS.CFGSTS was set. Every write operation on EP_CFG.BUFFERING
causes that controller increases internal counter holding the number
of reserved on-chip buffers. First time this register was updated in
function cdns3_ep_config before delegating SET_CONFIGURATION request
to class driver and again it was updated when class wanted to enable
endpoint. This patch fixes this issue by configuring endpoints
enabled by class driver in cdns3_gadget_ep_enable and others just
before status stage.

While I thought I had this correct (since it actually did reject modes
like I expected during testing), Ville Syrjala from Intel pointed out
that the logic here isn't correct. max_clock refers to the max data rate
supported by the DP encoder. So, limiting it to the output of ds_clock (which
refers to the maximum dotclock of the downstream DP device) doesn't make any
sense. Additionally, since we're using the connector's bpc as the canonical BPC
we should use this in mode_valid until we support dynamically setting the bpp
based on bandwidth constraints.
https://lists.freedesktop.org/archives/dri-devel/2020-September/280276.html
For more info.
So, let's rewrite this using Ville's advice.
v2:
* Ville pointed out I mixed up the dotclock and the link rate. So fix that...
* ...and also rename all the variables in this function to be more appropriately
labeled so I stop mixing them up.
* Reuse the bpp from the connector for now until we have dynamic bpp selection.
* Use use DIV_ROUND_UP for calculating the mode rate like i915 does, which we
should also have been doing from the start

Ville also pointed out that I got a lot of the logic here wrong as well, whoops.
While I don't think anyone's likely using 3D output with nouveau, the next patch
will make nouveau_conn_mode_valid() make a lot less sense. So, let's just get
rid of it and open-code it like before, while taking care to move the 3D frame
packing calculations on the dot clock into the right place.

With this we try to detect if the endianess switch works and assume LE if
not. Suggested by Ben.

Not entirely sure why this never came up when I originally tested this
(maybe some BIOSes already have this setup?) but the ->caps_init vfunc
appears to cause the display engine to throw an exception on driver
init, at least on my ThinkPad P72:
nouveau 0000:01:00.0: disp: chid 0 mthd 008c data 00000000 0000508c 0000102b
This is magic nvidia speak for "You need to have the DMA notifier offset
programmed before you can call NV507D_GET_CAPABILITIES." So, let's fix
this by doing that, and also perform an update afterwards to prevent
racing with the GPU when reading capabilities.
v2:
* Don't just program the DMA notifier offset, make sure to actually
perform an update
v3:
* Don't call UPDATE()
* Actually read the correct notifier fields, as apparently the
CAPABILITIES_DONE field lives in a different location than the main
NV_DISP_CORE_NOTIFIER_1 field. As well, 907d+ use a different
CAPABILITIES_DONE field then pre-907d cards.
v4:
* Don't forget to check the return value of core507d_read_caps()
v5:
* Get rid of NV50_DISP_CAPS_NTFY[14], use NV50_DISP_CORE_NTFY
* Disable notifier after calling GetCapabilities()

The user level OpenCL code shouldn't have to align start and end
addresses to a page boundary. That is better handled in the nouveau
driver. The npages field is also redundant since it can be computed
from the start and end addresses.

There is a regular need in the kernel to provide a way to declare having a
dynamically sized set of trailing elements in a structure. Kernel code should
always use “flexible array members”[1] for these cases. The older style of
one-element or zero-length arrays should no longer be used[2].

K2G devices still only use single parameter for power-domains property,
so check for this properly in the driver. Without this, every peripheral
fails to probe resulting in boot failure.

Pull networking fixes from Jakub Kicinski:
"Current release regressions:
- r8169: fix forced threading conflicting with other shared
interrupts; we tried to fix the use of raise_softirq_irqoff from an
IRQ handler on RT by forcing hard irqs, but this driver shares
legacy PCI IRQs so drop the _irqoff() instead
- tipc: fix memory leak caused by a recent syzbot report fix to
tipc_buf_append()
Current release - bugs in new features:
- devlink: Unlock on error in dumpit() and fix some error codes
- net/smc: fix null pointer dereference in smc_listen_decline()
Previous release - regressions:
- tcp: Prevent low rmem stalls with SO_RCVLOWAT.
- net: protect tcf_block_unbind with block lock
- ibmveth: Fix use of ibmveth in a bridge; the self-imposed filtering
to only send legal frames to the hypervisor was too strict
- net: hns3: Clear the CMDQ registers before unmapping BAR region;
incorrect cleanup order was leading to a crash
- bnxt_en - handful of fixes to fixes:
- Send HWRM_FUNC_RESET fw command unconditionally, even if there
are PCIe errors being reported
- Check abort error state in bnxt_open_nic().
- Invoke cancel_delayed_work_sync() for PFs also.
- Fix regression in workqueue cleanup logic in bnxt_remove_one().
- mlxsw: Only advertise link modes supported by both driver and
device, after removal of 56G support from the driver 56G was not
cleared from advertised modes
- net/smc: fix suppressed return code
Previous release - always broken:
- netem: fix zero division in tabledist, caused by integer overflow
- bnxt_en: Re-write PCI BARs after PCI fatal error.
- cxgb4: set up filter action after rewrites
- net: ipa: command payloads already mapped
Misc:
- s390/ism: fix incorrect system EID, it's okay to change since it
was added in current release
- vsock: use ns_capable_noaudit() on socket create to suppress false
positive audit messages"

Commit [bb1860efc817] changed the sink handling code introducing an
uninitialised pointer bug. This results in the default sink selection
failing.
Prior to commit:
static void etm_setup_aux(...)
<snip>
struct coresight_device *sink;
<snip>
/* First get the selected sink from user space. */
if (event->attr.config2) {
id = (u32)event->attr.config2;
sink = coresight_get_sink_by_id(id);
} else {
sink = coresight_get_enabled_sink(true);
}
<ctd>
*sink always initialised - possibly to NULL which triggers the
automatic sink selection.
After commit:
static void etm_setup_aux(...)
<snip>
struct coresight_device *sink;
<snip>
/* First get the selected sink from user space. */
if (event->attr.config2) {
id = (u32)event->attr.config2;
sink = coresight_get_sink_by_id(id);
}
<ctd>
*sink pointer uninitialised when not providing a sink on the perf command
line. This breaks later checks to enable automatic sink selection.
