[ Upstream commit c2af060d1c18beaec56351cf9c9bcbbc5af341a3 ]
The kcalloc() in dmirror_device_evict_chunk() will return null if the
physical memory has run out. As a result, if src_pfns or dst_pfns is
dereferenced, the null pointer dereference bug will happen.
Moreover, the device is going away. If the kcalloc() fails, the pages
mapping a chunk could not be evicted. So add a __GFP_NOFAIL flag in
kcalloc().
Finally, as there is no need to have physically contiguous memory, Switch
kcalloc() to kvcalloc() in order to avoid failing allocations.

[ Upstream commit ef302283ddfceaba2657923af3f90fd58e6dff06 ]
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 4f2bc4acbb1916b8cd2ce4bb3ba7b1cd7cb705fa ]
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.

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.

The .bpc = 6 implies .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG ,
add the missing bus_format. Add missing connector type and bus_flags
as well.
Documentation [1] 1.4 GENERAL SPECIFICATI0NS indicates this panel is
capable of both RGB 18bit/24bit panel, the current configuration uses
18bit mode, .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , .bpc = 6.
Support for the 24bit mode would require another entry in panel-simple
with .bus_format = MEDIA_BUS_FMT_RGB666_1X7X4_SPWG and .bpc = 8, which
is out of scope of this fix.

[ Upstream commit 5d1a7493343cc00d9019880b686e4e0a0f649531 ]
As documented in the description of the transfer() function of
"struct drm_dp_aux", the transfer() function can be called at any time
regardless of the state of the DP port. Specifically if the kernel has
the DP AUX character device enabled and userspace accesses
"/dev/drm_dp_auxN" directly then the AUX transfer function will be
called regardless of whether a DP device is connected.
For eDP panels we have a special rule where we wait (with a 5 second
timeout) for HPD to go high. This rule was important before all panels
drivers were converted to call wait_hpd_asserted() and actually can be
removed in a future commit.
For external DP devices we never checked for HPD. That means that
trying to access the DP AUX character device (AKA `hexdump -C
/dev/drm_dp_auxN`) would very, very slowly timeout. Specifically on my
system:
$ time hexdump -C /dev/drm_dp_aux0
hexdump: /dev/drm_dp_aux0: Connection timed out
real 0m8.200s
We want access to the drm_dp_auxN character device to fail faster than
8 seconds when no DP cable is plugged in.
Let's add a test to make transfers fail right away if a device isn't
plugged in. Rather than testing the HPD line directly, we have the
dp_display module tell us when AUX transfers should be enabled so we
can handle cases where HPD is signaled out of band like with Type C.
