Moreover, the device is going away. If the kcalloc() fails, the pages

kcalloc().
Finally, as there is no need to have physically contiguous memory, Switch
kcalloc() to kvcalloc() in order to avoid failing allocations.

[ Upstream commit ef302283dd ]
mlx5 has a built in self-test at driver startup to evaluate if the
platform supports write combining to generate a 64 byte PCIe TLP or
not. This has proven necessary because a lot of common scenarios end up
with broken write combining (especially inside virtual machines) and there
is other way to learn this information.
This self test has been consistently failing on new ARM64 CPU
designs (specifically with NVIDIA Grace's implementation of Neoverse
V2). The C loop around writeq() generates some pretty terrible ARM64
assembly, but historically this has worked on a lot of existing ARM64 CPUs
till now.
We see it succeed about 1 time in 10,000 on the worst effected
systems. The CPU architects speculate that the load instructions
interspersed with the stores makes the WC buffers statistically flush too
often and thus the generation of large TLPs becomes infrequent. This makes
the boot up test unreliable in that it indicates no write-combining,
however userspace would be fine since it uses a ST4 instruction.
Further, S390 has similar issues where only the special zpci_memcpy_toio()
will actually generate large TLPs, and the open coded loop does not
trigger it at all.
Fix both ARM64 and S390 by switching to __iowrite64_copy() which now
provides architecture specific variants that have a high change of
generating a large TLP with write combining. x86 continues to use a
similar writeq loop in the generate __iowrite64_copy().

In rxe_send() a ref is taken on the qp to keep it alive until the
kfree_skb() has a chance to call the skb destructor rxe_skb_tx_dtor()
which drops the reference. If the packet has an incorrect protocol the
error path just calls kfree_skb() which will call the destructor which
will drop the ref. Currently the driver also calls rxe_put() which is
incorrect. Additionally since the packets sent to rxe_send() are under the
control of the driver and it only ever produces IPV4 or IPV6 packets the
simplest fix is to remove all the code in this block.

In rxe_comp_queue_pkt() an incoming response packet skb is enqueued to the
resp_pkts queue and then a decision is made whether to run the completer
task inline or schedule it. Finally the skb is dereferenced to bump a 'hw'
performance counter. This is wrong because if the completer task is
already running in a separate thread it may have already processed the skb
and freed it which can cause a seg fault. This has been observed
infrequently in testing at high scale.
This patch fixes this by changing the order of enqueuing the packet until
after the counter is accessed.

[ Upstream commit 7cf0324ba0 ]
When SPI transfer is being prepared, the spi-s3c64xx driver will call
clk_set_rate() to change the rate of SPI source clock (IPCLK). But IPCLK
is a gate (leaf) clock, so it must propagate the rate change up the
clock tree, so that corresponding MUX/DIV clocks can actually change
their values. Add CLK_SET_RATE_PARENT flag to corresponding clocks for
all USI instances in GS101 PERIC1: USI{0, 9, 10, 11, 12, 13}. This change
involves the following clocks:
PERIC1 USI*:
Clock Div range MUX Selection
-------------------------------------------------------------------
gout_peric1_peric1_top0_ipclk_* - -
dout_peric1_usi*_usi /1..16 -
mout_peric1_usi*_usi_user - {24.5 MHz, 400 MHz}
With input clock of 400 MHz this scheme provides the following IPCLK
rate range, for each USI block:
PERIC1 USI*: 1.5 MHz ... 400 MHz
Accounting for internal /4 divider in SPI blocks, and because the max
SPI frequency is limited at 50 MHz, it gives us next SPI SCK rates:
PERIC1 USI_SPI*: 384 KHz ... 49.9 MHz
Which shall be fine for the applications of the SPI bus.
Note that with this we allow the reparenting of the MUX_USIx clocks to
OSCCLK. Each instance of the USI IP has its own MUX_USI clock, thus the
reparenting of a MUX_USI clock corresponds to a single instance of the
USI IP. The datasheet mentions OSCCLK just in the low-power mode
context, but the downstream driver reparents too the MUX_USI clocks to
OSCCLK. Follow the downstream driver and do the same.

[ Upstream commit 7b54d9113c ]
Introduce nMUX() for MUX clocks that can be reparented on clock rate
change. "nMUX" comes from "n-to-1 selector", hopefully emphasising that
the selector can change on clock rate changes. Ideally MUX/MUX_F()
should change to not have the CLK_SET_RATE_NO_REPARENT flag set by
default, and all their users to be updated to add the flag back
(like in the case of DIV and GATE). But this is a very intrusive change
and because for now only GS101 allows MUX reparenting on clock rate
change, stick with nMUX().
GS101 defines MUX clocks that are dedicated for each instance of the IP.
One example is USI IP (SPI, I2C, serial). The reparenting of these MUX
clocks will not affect other instances of the same IP or different IPs
altogether.
When SPI transfer is being prepared, the spi-s3c64xx driver will call
clk_set_rate() to change the rate of SPI source clock (IPCLK). But IPCLK
is a gate (leaf) clock, so it must propagate the rate change up the

The offset of the CONFIG_CTL_U register defined for the Stromer
PLL is wrong. It is not aligned on a 4 bytes boundary which might
causes errors in regmap operations.
Maybe the intention behind of using the 0xff value was to indicate
that the register is not implemented in the PLL, but this is not
verified anywhere in the code. Moreover, this value is not used
even in other register offset arrays despite that those PLLs also
have unimplemented registers.
Additionally, on the Stromer PLLs the current code only touches
the CONFIG_CTL_U register if the result of pll_has_64bit_config()
is true which condition is not affected by the change.
Due to the reasons above, simply remove the CONFIG_CTL_U entry
from the Stromer specific array.

There is no error handling now in __iommu_set_group_pasid(), it relies on
its caller to loop all the devices to undo the pasid attachment. This is
not self-contained and has drawbacks. It would result in unnecessary
remove_dev_pasid() calls on the devices that have not been attached to the
new domain. But the remove_dev_pasid() callback would get the new domain
from the group->pasid_array. So for such devices, the iommu driver won't
find the attachment under the domain, hence unable to do cleanup. This may
not be a real problem today. But it depends on the implementation of the
underlying iommu driver. e.g. the intel iommu driver would warn for such
devices. Such warnings are unnecessary.
To solve the above problem, it is necessary to handle the error within
__iommu_set_group_pasid(). It only loops the devices that have attached
to the new domain, and undo it.

When the source device is operating above 1.5 Gbps per lane, it needs to

DPHY is initialized after the source stream is started, then it might
miss the sequence and not be able to receive data properly. Move the
start of source subdev to the end of the sequence to make sure

[ Upstream commit e0a200ab4b ]
DisplayID spec v1.3 revision history notes do claim that
the toplogy block was added in v1.3 so requiring structure
v1.2 would seem correct, but there is at least one EDID in
edid.tv with a topology block and structure v1.0. And
there are also EDIDs with DisplayID structure v1.3 which
seems to be totally incorrect as DisplayID spec v1.3 lists
structure v1.2 as the only legal value.
Unfortunately I couldn't find copies of DisplayID spec
v1.0-v1.2 anywhere (even on vesa.org), so I'll have to
go on empirical evidence alone.
We used to parse the topology block on all v1.x
structures until the check for structure v2.0 was added.
Let's go back to doing that as the evidence does suggest
that there are DisplayIDs in the wild that would miss
out on the topology stuff otherwise.
Also toss out DISPLAY_ID_STRUCTURE_VER_12 entirely as
it doesn't appear we can really use it for anything.
I *think* we could technically skip all the structure
version checks as the block tags shouldn't conflict
between v2.0 and v1.x. But no harm in having a bit of
extra sanity checks I guess.
So far I'm not aware of any user reported regressions
from overly strict check, but I do know that it broke
igt/kms_tiled_display's fake DisplayID as that one
gets generated with structure v1.0.

[ Upstream commit 07731053d1 ]
Logitech Rally Bar devices, despite behaving as UVC cameras, have a
different power management system that the other cameras from Logitech.
USB_QUIRK_RESET_RESUME is applied to all the UVC cameras from Logitech
at the usb core. Unfortunately, USB_QUIRK_RESET_RESUME causes undesired
USB disconnects in the Rally Bar that make them completely unusable.
There is an open discussion about if we should fix this in the core or
add a quirk in the UVC driver. In order to enable this hardware, let's
land this patch first, and we can revert it later if there is a
different conclusion.
