[why]
currently dc has never reset this dpcd_cap.dpcd_rev.
[how]
ideally we should reset this before redo detection.
change the passive dongle only for now to reduce the impact.

Commit 65d6470d139a ("ibmvnic: clean pending indirect buffs during reset")
intended to remove the call to ibmvnic_tx_scrq_flush() when the
->resetting flag is true and was tested that way. But during the final
rebase to net-next, the hunk got applied to a block few lines below
(which happened to have the same diff context) and the wrong call to
ibmvnic_tx_scrq_flush() got removed.
Fix that by removing the correct ibmvnic_tx_scrq_flush() and restoring
the one that was incorrectly removed.

====================
Fix PMTU for ESP-in-UDP encapsulation
Bug 213669 uncovered regression in PMTU discovery for UDP-encapsulated
routes and some incorrect usage in udp tunnel fields. This series fixes
problems and also adds such case for selftests
v3:
- update checking logic to account SCTP use case
v2:
- remove refactor code that was in first patch
- move checking logic to __udp{4,6}_lib_err_encap
- add more tests, especially routed configuration

Commit d26796ae5894 ("udp: check udp sock encap_type in __udp_lib_err")
added checks for encapsulated sockets but it broke cases when there is
no implementation of encap_err_lookup for encapsulation, i.e. ESP in
UDP encapsulation. Fix it by calling encap_err_lookup only if socket
implements this method otherwise treat it as legal socket.

This is an use-after-free issue caused by not updating asoc->shkey after
it was replaced in the key list asoc->endpoint_shared_keys, and the old
key was freed.
This patch is to fix by also updating active_key for asoc when old key is
being replaced with a new one. Note that this issue doesn't exist in
sctp_auth_del_key_id(), as it's not allowed to delete the active_key
from the asoc.

When registering the MDIO bus for a r8169 device, we use the PCI
bus/device specifier as a (seemingly) unique device identifier.
However the very same BDF number can be used on another PCI segment,
which makes the driver fail probing:
[ 27.544136] r8169 0002:07:00.0: enabling device (0000 -> 0003)
[ 27.559734] sysfs: cannot create duplicate filename '/class/mdio_bus/r8169-700'
....
[ 27.684858] libphy: mii_bus r8169-700 failed to register
[ 27.695602] r8169: probe of 0002:07:00.0 failed with error -22
Add the segment number to the device name to make it more unique.
This fixes operation on ARM N1SDP boards, with two boards connected
together to form an SMP system, and all on-board devices showing up
twice, just on different PCI segments. A similar issue would occur on
large systems with many PCI slots and multiple RTL8169 NICs.

Variable ret is set to -ENOENT and -ENOMEM but this value is never
read as it is overwritten or not used later on, hence it is a
redundant assignment and can be removed.
Cleans up the following clang-analyzer warning:

[clang-analyzer-deadcode.DeadStores].
fs/afs/dir.c:659:2: warning: Value stored to 'ret' is never read

[DH made the following modifications:
- In afs_rename(), -ENOMEM should be placed in op->error instead of ret,
rather than the assignment being removed entirely. afs_put_operation()
will pick it up from there and return it.
- If afs_sillyrename() fails, its error code should be placed in op->error
rather than in ret also.

To quote Alexey[1]:
I was adding custom tracepoint to the kernel, grabbed full F34 kernel
.config, disabled modules and booted whole shebang as VM kernel.
Then did
perf record -a -e ...
It crashed:
general protection fault, probably for non-canonical address 0x435f5346592e4243: 0000 [#1] SMP PTI
CPU: 1 PID: 842 Comm: cat Not tainted 5.12.6+ #26
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33 04/01/2014
RIP: 0010:t_show+0x22/0xd0
Then reproducer was narrowed to
# cat /sys/kernel/tracing/printk_formats
Original F34 kernel with modules didn't crash.
So I started to disable options and after disabling AFS everything
started working again.
The root cause is that AFS was placing char arrays content into a
section full of _pointers_ to strings with predictable consequences.
Non canonical address 435f5346592e4243 is "CB.YFS_" which came from
CM_NAME macro.
Steps to reproduce:
CONFIG_AFS=y
CONFIG_TRACING=y
# cat /sys/kernel/tracing/printk_formats
Fix this by the following means:
(1) Add enum->string translation tables in the event header with the AFS
and YFS cache/callback manager operations listed by RPC operation ID.
(2) Modify the afs_cb_call tracepoint to print the string from the
translation table rather than using the string at the afs_call name
pointer.
(3) Switch translation table depending on the service we're being accessed
as (AFS or YFS) in the tracepoint print clause. Will this cause
problems to userspace utilities?
Note that the symbolic representation of the YFS service ID isn't
available to this header, so I've put it in as a number. I'm not sure
if this is the best way to do this.
(4) Remove the name wrangling (CM_NAME) macro and put the names directly
into the afs_call_type structs in cmservice.c.

My local syzbot instance hit GPF in ttm_bo_release().
Unfortunately, syzbot didn't produce a reproducer for this, but I
found out possible scenario:
drm_gem_vram_create() <-- drm_gem_vram_object kzalloced
(bo embedded in this object)
ttm_bo_init()
ttm_bo_init_reserved()
ttm_resource_alloc()
man->func->alloc() <-- allocation failure
ttm_bo_put()
ttm_bo_release()
ttm_mem_io_free() <-- bo->resource == NULL passed
as second argument
*GPF*
Added NULL check inside ttm_mem_io_free() to prevent reported GPF and
make this function NULL save in future.
Same problem was in ttm_bo_move_to_lru_tail() as Christian reported.
ttm_bo_move_to_lru_tail() is called in ttm_bo_release() and mem pointer
can be NULL as well as in ttm_mem_io_free().

This reverts commit c742199a014de23ee92055c2473d91fe5561ffdf.
c742199a014d ("mm/pgtable: add stubs for {pmd/pub}_{set/clear}_huge")
breaks arm64 in at least two ways for configurations where PUD or PMD
folding occur:
1. We no longer install huge-vmap mappings and silently fall back to
page-granular entries, despite being able to install block entries
at what is effectively the PGD level.
2. If the linear map is backed with block mappings, these will now
silently fail to be created in alloc_init_pud(), causing a panic
early during boot.
The pgtable selftests caught this, although a fix has not been
forthcoming and Christophe is AWOL at the moment, so just revert the
change for now to get a working -rc3 on which we can queue patches for
5.15.
A simple revert breaks the build for 32-bit PowerPC 8xx machines, which
rely on the default function definitions when the corresponding
page-table levels are folded, since commit a6a8f7c4aa7e ("powerpc/8xx:
add support for huge pages on VMAP and VMALLOC"), eg:
powerpc64-linux-ld: mm/vmalloc.o: in function `vunmap_pud_range':
linux/mm/vmalloc.c:362: undefined reference to `pud_clear_huge'
To avoid that, add stubs for pud_clear_huge() and pmd_clear_huge() in
arch/powerpc/mm/nohash/8xx.c as suggested by Christophe.

lr (register x30), causing __arm_smccc_hvc() to return to itself and
crash. Save lr on the stack before calling __arm_smccc_sve_check(). Save

The register_gop_device() function registers an "efi-framebuffer" platform
device to match against the efifb driver, to have an early framebuffer for
EFI platforms.
But there is already support to do exactly the same by the Generic System
Framebuffers (sysfb) driver. This used to be only for X86 but it has been
moved to drivers/firmware and could be reused by other architectures.
Also, besides supporting registering an "efi-framebuffer", this driver can
register a "simple-framebuffer" allowing to use the siple{fb,drm} drivers
on non-X86 EFI platforms. For example, on aarch64 these drivers can only
be used with DT and doesn't have code to register a "simple-frambuffer"
platform device when booting with EFI.
For these reasons, let's remove the register_gop_device() duplicated code
and instead move the platform specific logic that's there to sysfb driver.

The x86 architecture has generic support to register a system framebuffer
platform device. It either registers a "simple-framebuffer" if the config
option CONFIG_X86_SYSFB is enabled, or a legacy VGA/VBE/EFI FB device.
But the code is generic enough to be reused by other architectures and can
be moved out of the arch/x86 directory.
This will allow to also support the simple{fb,drm} drivers on non-x86 EFI
platforms, such as aarch64 where these drivers are only supported with DT.

This reverts commit 0bd860493f81eb2a46173f6f5e44cc38331c8dbd.
While the patch was working as stated,ie preventing the L850-GL LTE modem
from crashing on some U3 wake-ups due to a race condition between the
host wake-up and the modem-side wake-up, when using the MBIM interface,
this would force disabling the USB runtime PM on the device.
The increased power consumption is significant for LTE laptops,
and given that with decently recent modem firmwares, when the modem hits
the bug, it automatically recovers (ie it drops from the bus, but
automatically re-enumerates after less than half a second, rather than being
stuck until a power cycle as it was doing with ancient firmware), for
most people, the trade-off now seems in favor of re-enabling it by
default.
For people with access to the platform code, the bug can also be worked-around
successfully by changing the USB3 LFPM polling off-time for the XHCI
controller in the BIOS code.

When the last path to a ns_head drops the current code
removes the ns_head from the subsystem list, but will only
delete the disk itself if the last reference to the ns_head
drops. This is causing an refcounting imbalance eg when
applications have a reference to the disk, as then they'll
never get notified that the disk is in fact dead.
This patch moves the call 'del_gendisk' into nvme_mpath_check_last_path(),
ensuring that the disk can be properly removed and applications get the

Commit 0112b7ce68ea ("usb: dwc2: Update dwc2_handle_usb_suspend_intr
function.") changed the way the driver handles power down modes in a such
way that it uses clock gating when no other power down mode is available.
This however doesn't work well on the DWC2 implementation used on the
Samsung SoCs. When a clock gating is enabled, system hangs. It looks that
the proper clock gating requires some additional glue code in the shared
USB2 PHY and/or Samsung glue code for the DWC2. To restore driver
operation on the Samsung SoCs simply skip enabling clock gating mode
until one finds what is really needed to make it working reliably.

When the dwc2 platform device is removed, it unregisters the generic
phy. usb_remove_phy() is called and the dwc2 usb_phy is removed from the
"phy_list", but the uevent may still attempt to get the usb_phy from the
list, resulting in a page fault bug. Currently we can't access the usb_phy
from the "phy_list" after the device is removed. As a fix check to make
sure that we can get the usb_phy before moving forward with the uevent.
