One of the SUSE QA tests triggered:
localhost kernel: efi: Failed to lookup EFI memory descriptor for 0x000000003dcf8000
which comes from x86's version of efi_arch_mem_reserve() trying to
reserve a memory region. Usually, that function expects
EFI_BOOT_SERVICES_DATA memory descriptors but the above case is for the
MOKvar table which is allocated in the EFI shim as runtime services.
That lead to a fix changing the allocation of that table to boot services.
However, that fix broke booting SEV guests with that shim leading to
this kernel fix
8d651ee9c71b ("x86/ioremap: Map EFI-reserved memory as encrypted for SEV")
which extended the ioremap hint to map reserved EFI boot services as
decrypted too.
However, all that wasn't needed, IMO, because that error message in
efi_arch_mem_reserve() was innocuous in this case - if the MOKvar table
is not in boot services, then it doesn't need to be reserved in the
first place because it is, well, in runtime services which *should* be
reserved anyway.
So do that reservation for the MOKvar table only if it is allocated
in boot services data. I couldn't find any requirement about where
that table should be allocated in, unlike the ESRT which allocation is
mandated to be done in boot services data by the UEFI spec.

The IOC firmware assumes that the host driver is still alive after shutdown
and continues to post events to host memory (due to faulty expander phy
links, etc). This leads to 0x2666 (a bus fault occurred during a host-IOC
memory access).
Perform an IOC soft reset as part of shutdown to disable event posting.

Fix an 11-year old bug in ngene_command_config_free_buf() while
addressing the following warnings caught with -Warray-bounds:
arch/alpha/include/asm/string.h:22:16: warning: '__builtin_memcpy' offset [12, 16] from the object at 'com' is out of the bounds of referenced subobject 'config' with type 'unsigned char' at offset 10 [-Warray-bounds]
arch/x86/include/asm/string_32.h:182:25: warning: '__builtin_memcpy' offset [12, 16] from the object at 'com' is out of the bounds of referenced subobject 'config' with type 'unsigned char' at offset 10 [-Warray-bounds]
The problem is that the original code is trying to copy 6 bytes of
data into a one-byte size member _config_ of the wrong structue
FW_CONFIGURE_BUFFERS, in a single call to memcpy(). This causes a
legitimate compiler warning because memcpy() overruns the length
of &com.cmd.ConfigureBuffers.config. It seems that the right
structure is FW_CONFIGURE_FREE_BUFFERS, instead, because it contains
6 more members apart from the header _hdr_. Also, the name of
the function ngene_command_config_free_buf() suggests that the actual
intention is to ConfigureFreeBuffers, instead of ConfigureBuffers
(which takes place in the function ngene_command_config_buf(), above).
Fix this by enclosing those 6 members of struct FW_CONFIGURE_FREE_BUFFERS
into new struct config, and use &com.cmd.ConfigureFreeBuffers.config as
the destination address, instead of &com.cmd.ConfigureBuffers.config,
when calling memcpy().
This also helps with the ongoing efforts to globally enable
-Warray-bounds and get us closer to being able to tighten the
FORTIFY_SOURCE routines on memcpy().

As of now any communication between CGXs PFs and
their VFs within the system is possible only by
external switches sending packets back to the
system. This patch adds internal switching support.
Broadcast packet replication is not covered here.
RVU admin function (AF) maintains MAC addresses
of all interfaces in the system. When switching is
enabled, MCAM entries are allocated to install rules
such that packets with DMAC matching any of the
internal interface MAC addresses is punted back
into the system via the loopback channel.
On the receive side the default unicast rules
are modified to not check for ingress channel.
So any packet with matching DMAC irrespective of
which interface it is coming from will be forwarded
to the respective PF/VF interface.
The transmit side rules and default unicast rules
are updated if user changes MAC address of an interface.

AF till now only manages the allocation and freeing of
MCAM rules for other PF/VFs in system. To implement
L2 switching between all CGX mapped PF and VFs, AF
requires MCAM entries for DMAC rules for each PF and VF.
This patch modifies AF driver such that AF can also
allocate MCAM rules and install rules for other
PFs and VFs. All the checks like channel verification
for RX rules and PF_FUNC verification for TX rules are
relaxed in case AF is allocating or installing rules.
Also all the entry and counter to owner mappings are
set to NPC_MCAM_INVALID_MAP when they are free indicating
those are not allocated to AF nor PF/VFs.
This patch also ensures that AF allocated and installed
entries are displayed in debugfs.

For enabling VF-VF switching the packets egressing
out of CGX mapped VFs needed to be sent to LBK
so that same packets are received back to the system.
But the LBK link also needs to be enabled in addition
to a VF's mapped CGX_LMAC link otherwise hardware
raises send error interrupt indicating selected LBK
link is not enabled in NIX_AF_TL3_TL2X_LINKX_CFG register.
Hence this patch enables all LBK links in
TL3_TL2_LINKX_CFG registers.
Also to enable packet flow between PFs/VFs of NIX0
to PFs/VFs of NIX1(in 98xx silicon) the NPC TX DMAC
rules has to be installed such that rules must be hit
for any TX interface i.e., NIX0-TX or NIX1-TX provided
DMAC match creteria is met. Hence this patch changes the
behavior such that MCAM is programmed to match with any
NIX0/1-TX interface for TX rules.

The current PTP initialization logic does not account for firmware
reset that may cause PTP capability to change. The valid pointer
bp->ptp_cfg is used to indicate that the device is capable of PTP
and that it has been initialized. So we must clean up bp->ptp_cfg
and free it if the firmware after reset does not support PTP.

The device needs to be in ifup state for PTP to function, so move
bnxt_ptp_init() to bnxt_open(). This means that the PHC will be
registered during bnxt_open().
This also makes firmware reset work correctly. PTP configurations
may change after firmware upgrade or downgrade. bnxt_open() will
be called after firmware reset, so it will work properly.
bnxt_ptp_start() is now incorporated into bnxt_ptp_init(). We now
also need to call bnxt_ptp_clear() in bnxt_close().

bnxt_half_open_nic() is called during during ethtool self test and is
protected by rtnl_lock. Firmware reset can be happening at the same
time. Only critical portions of the entire firmware reset sequence
are protected by the rtnl_lock. It is possible that bnxt_half_open_nic()
can be called when the firmware reset sequence is aborting. In that
case, bnxt_half_open_nic() needs to check if the ABORT_ERR flag is set
and abort if it is. The ethtool self test will fail but the NIC will be
brought to a consistent IF_DOWN state.
Without this patch, if bnxt_half_open_nic() were to continue in this
error state, it may crash like this:

This reverts commit 9e31c1fe45d555a948ff66f1f0e3fe1f83ca63f7. Ever
since that commit, we've been having issues where a hang in one client
can propagate to another. In particular, a hang in an app can propagate
to the X server which causes the whole desktop to lock up.
Error propagation along fences sound like a good idea, but as your bug
shows, surprising consequences, since propagating errors across security
boundaries is not a good thing.
What we do have is track the hangs on the ctx, and report information to
userspace using RESET_STATS. That's how arb_robustness works. Also, if my
understanding is still correct, the EIO from execbuf is when your context
is banned (because not recoverable or too many hangs). And in all these
cases it's up to userspace to figure out what is all impacted and should
be reported to the application, that's not on the kernel to guess and
automatically propagate.
What's more, we're also building more features on top of ctx error
reporting with RESET_STATS ioctl: Encrypted buffers use the same, and the
userspace fence wait also relies on that mechanism. So it is the path
going forward for reporting gpu hangs and resets to userspace.
So all together that's why I think we should just bury this idea again as
not quite the direction we want to go to, hence why I think the revert is
the right option here.

This reverts 686c7c35abc2 ("drm/i915/gem: Asynchronous cmdparser"). The
justification for this commit in the git history was a vague comment
about getting it out from under the struct_mutex. While this may
improve perf for some workloads on Gen7 platforms where we rely on the
command parser for features such as indirect rendering, no numbers were
provided to prove such an improvement. It claims to closed two
gitlab/bugzilla issues but with no explanation whatsoever as to why or
what bug it's fixing.
Meanwhile, by moving command parsing off to an async callback, it leaves
us with a problem of what to do on error. When things were synchronous,
EXECBUFFER2 would fail with an error code if parsing failed. When
moving it to async, we needed another way to handle that error and the
solution employed was to set an error on the dma_fence and then trust
that said error gets propagated to the client eventually. Moving back
to synchronous will help us untangle the fence error propagation mess.
This also reverts most of 0edbb9ba1bfe ("drm/i915: Move cmd parser
pinning to execbuffer") which is a refactor of some of our allocation
paths for asynchronous parsing. Now that everything is synchronous, we
don't need it.

The original implementation of RPM handling in probe() was mostly
correct, except it failed to call pm_runtime_get_*() to activate the
hardware. The subsequent fix, 734882a8bf98 ("spi: cadence: Correct
initialisation of runtime PM"), breaks the implementation further,
to the point where the system using this hard IP on ZynqMP hangs on
boot, because it accesses hardware which is gated off.
Undo 734882a8bf98 ("spi: cadence: Correct initialisation of runtime
PM") and instead add missing pm_runtime_get_noresume() and move the
RPM disabling all the way to the end of probe(). That makes ZynqMP
not hang on boot yet again.

The vmbus module uses a rotational algorithm to assign target CPUs to
a device's channels. Depending on the timing of different device's channel
offers, different channels of a device may be assigned to the same CPU.
For example on a VM with 2 CPUs, if NIC A and B's channels are offered
in the following order, NIC A will have both channels on CPU0, and
NIC B will have both channels on CPU1 -- see below. This kind of
assignment causes RSS load that is spreading across different channels
to end up on the same CPU.
Timing of channel offers:
NIC A channel 0
NIC B channel 0
NIC A channel 1
NIC B channel 1

Update the vmbus CPU assignment algorithm to avoid duplicate CPU
assignments within a device.
The new algorithm iterates num_online_cpus + 1 times.
The existing rotational algorithm to find "next NUMA & CPU" is still here.
But if the resulting CPU is already used by the same device, it will try
the next CPU.
In the last iteration, it assigns the channel to the next available CPU
like the existing algorithm. This is not normally expected, because
during device probe, we limit the number of channels of a device to
be <= number of online CPUs.

driver we might not match and return that we don't want attr visible in
sysfs. The patch fixes this by setting the type when we figure out what the
param is.

According to reference guides mt7530 (mt7620) and mt7531:
NOTE: When IVL is reset, MAC[47:0] and FID[2:0] will be used to
read/write the address table. When IVL is set, MAC[47:0] and CVID[11:0]
will be used to read/write the address table.
Since the function only fills in CVID and no FID, we need to set the
IVL bit. The existing code does not set it.
This is a fix for the issue I dropped here earlier:
http://lists.infradead.org/pipermail/linux-mediatek/2021-June/025697.html
With this patch, it is now possible to delete the 'self' fdb entry
manually. However, wifi roaming still has the same issue, the entry
does not get deleted automatically. Wifi roaming also needs a fix
somewhere else to function correctly in combination with vlan.

Commit 72a7cf0aec0c ("drm/amd/display: Keep linebuffer pixel depth at
30bpp for DCE-11.0.") doesn't seems to have fixed 10bit 4K rendering over
DisplayPort for CIK GPUs. On my machine with a HAWAII GPU I get a broken
image that looks like it has an effective resolution of 1920x1080 but
scaled up in an irregular way. Reverting the commit or applying this
patch fixes the problem on v5.14-rc1.

cadence-quadspi has a builtin Auto-HW polling funtionality using which
it keep tracks of completion of write operations. When Auto-HW polling
is enabled, it automatically initiates status register read operation,
until the flash clears its busy bit.
cadence-quadspi controller doesn't allow an address phase when
auto-polling the busy bit on the status register. Unlike SPI NOR
flashes, SPI NAND flashes do require the address of status register
when polling the busy bit using the read register operation. As
Auto-HW polling is enabled by default, cadence-quadspi returns a
timeout for every write operation after an indefinite amount of
polling on SPI NAND flashes.
Disable Auto-HW polling completely as the spi-nor core, spinand core,
etc. take care of polling the busy bit on their own.

kexec_load_file() relies on the memblock infrastructure to avoid
stamping over regions of memory that are essential to the survival
of the system.
However, nobody seems to agree how to flag these regions as reserved,
and (for example) EFI only publishes its reservations in /proc/iomem
for the benefit of the traditional, userspace based kexec tool.
On arm64 platforms with GICv3, this can result in the payload being
placed at the location of the LPI tables. Shock, horror!
Let's augment the EFI reservation code with a memblock_reserve() call,
protecting our dear tables from the secondary kernel invasion.

KFD Thunk maps invisible VRAM BOs with PROT_NONE, MAP_PRIVATE.
is_cow_mapping returns true for these mappings, which causes mmap to fail
in ttm_bo_mmap_obj.
As a workaround, clear VM_MAYWRITE for PROT_NONE-COW mappings. This
should prevent the mapping from ever becoming writable and makes
is_cow_mapping(vm_flags) false.
