The old MIPS implementation of dma_cache_sync() didn't use the dev argument,
but commit c9eb6172c328 ("dma-mapping: turn dma_cache_sync into a
dma_map_ops method") changed that, so we now need to set dev.parent.

Currently there is an underlying assumption that i915_request_unsubmit()
is synchronous wrt the GPU -- that is the request is no longer in flight
as we remove it. In the near future that may change, and this may upset
our signaling as we can process an interrupt for that request while it
is no longer in flight.
CPU0 CPU1
intel_engine_breadcrumbs_irq
(queue request completion)
i915_request_cancel_signaling
... ...
i915_request_enable_signaling
dma_fence_signal
Hence in the time it took us to drop the lock to signal the request, a
preemption event may have occurred and re-queued the request. In the
process, that request would have seen I915_FENCE_FLAG_SIGNAL clear and
so reused the rq->signal_link that was in use on CPU0, leading to bad
pointer chasing in intel_engine_breadcrumbs_irq.
A related issue was that if someone started listening for a signal on a
completed but no longer in-flight request, we missed the opportunity to
immediately signal that request.
Furthermore, as intel_contexts may be immediately released during
request retirement, in order to be entirely sure that
intel_engine_breadcrumbs_irq may no longer dereference the intel_context
(ce->signals and ce->signal_link), we must wait for irq spinlock.
In order to prevent the race, we use a bit in the fence.flags to signal
the transfer onto the signal list inside intel_engine_breadcrumbs_irq.
For simplicity, we use the DMA_FENCE_FLAG_SIGNALED_BIT as it then
quickly signals to any outside observer that the fence is indeed signaled.

v3: And the test_and_set_bit()

On HSW the pipe A panel fitter lives inside the display power well,
and the input MUX for the EDP transcoder needs to be configured
appropriately to route the data through the power well as needed.
Changing the MUX setting is not allowed while the pipe is active,
so we need to force a full modeset whenever we need to change it.
Currently we may end up doing a fastset which won't change the
MUX settings, but it will drop the power well reference, and that
kills the pipe.

On many (all?) the Gemini Lake systems we work with, there is frequent
momentary graphical corruption at the top of the screen, and it seems
that disabling framebuffer compression can avoid this.
The ticket was reported 6 months ago and has already affected a
multitude of users, without any real progress being made. So, lets
disable framebuffer compression on GeminiLake until a solution is found.

In cpufreq_init_policy() we will check if there's last_governor for target
and setpolicy type. However last_governor is set only if has_target() is
true in cpufreq_offline(). That means find last_governor for setpolicy
type is pointless. Also new_policy.governor will not be used if ->setpolicy
callback is set in cpufreq_set_policy().
Moreover, there's duplicate ->setpolicy check in using default policy path.

Commit 31fd85816dbe ("bpf: permits narrower load from bpf program
context fields") made the verifier add AND instructions to clear the
unwanted bits with a mask when doing a narrow load. The mask is
computed with
(1 << size * 8) - 1
where "size" is the size of the narrow load. When doing a 4 byte load
of a an 8 byte field the verifier shifts the literal 1 by 32 places to
the left. This results in an overflow of a signed integer, which is an
undefined behavior. Typically, the computed mask was zero, so the
result of the narrow load ended up being zero too.
Cast the literal to long long to avoid overflows. Note that narrow
load of the 4 byte fields does not have the undefined behavior,
because the load size can only be either 1 or 2 bytes, so shifting 1
by 8 or 16 places will not overflow it. And reading 4 bytes would not
be a narrow load of a 4 bytes field.

Depending on used versions of libbpf, Clang, and kernel, it's possible to
have valid BPF object files with valid BTF information, that still won't
load successfully due to Clang emitting newer BTF features (e.g.,
BTF_KIND_FUNC, .BTF.ext's line_info/func_info, BTF_KIND_DATASEC, etc), that
are not yet supported by older kernel.
This patch adds detection of BTF features and sanitizes BPF object's BTF
by substituting various supported BTF kinds, which have compatible layout:
- BTF_KIND_FUNC -> BTF_KIND_TYPEDEF
- BTF_KIND_FUNC_PROTO -> BTF_KIND_ENUM
- BTF_KIND_VAR -> BTF_KIND_INT
- BTF_KIND_DATASEC -> BTF_KIND_STRUCT
Replacement is done in such a way as to preserve as much information as
possible (names, sizes, etc) where possible without violating kernel's
validation rules.
v2->v3:
- remove duplicate #defines from libbpf_util.h
v1->v2:

- switch SK storage BTF to use new libbpf__probe_raw_btf()

The script broke on parsing function prototype for bpf_strtoul(). This
is because the last argument for the function is a pointer to an
"unsigned long". The current version of the script only accepts "const"
and "struct", but not "unsigned", at the beginning of argument types
made of several words.
One solution could be to add "unsigned" to the list, but the issue could
come up again in the future (what about "long int"?). It turns out we do
not need to have such restrictions on the words: so let's simply accept
any series of words instead.

Vladimir Oltean says:
====================
Fix a bug and avoid dangerous usage patterns around DSA_SKB_CB
Making DSA use the sk_buff control block was my idea during the
'Traffic-support-for-SJA1105-DSA-driver' patchset, and I had also
introduced a series of macro helpers that turned out to not be so
helpful:
1. DSA_SKB_ZERO() zeroizes the 48-byte skb->cb area, but due to the high
performance impact in the hotpath it was only intended to be called
from the timestamping path. But it turns out that not zeroizing it
has uncovered the reading of an uninitialized member field of
DSA_SKB_CB, so in the future just be careful about what needs
initialization and remove this macro.
2. DSA_SKB_CLONE() contains a flaw in its body definition (originally
put there to silence checkpatch.pl) and is unusable at this point
(will only cause NPE's when used). So remove it.
3. For DSA_SKB_COPY() the same performance considerations apply as above
and therefore it's best to prune this function before it reaches a
stable kernel and potentially any users.

It's best to not expose this, due to the performance hit it may cause

This does not cause any bug now because it has no users, but its body
contains two pointer definitions within a code block:
struct sk_buff *clone = _clone; \
struct sk_buff *skb = _skb; \
When calling the macro as DSA_SKB_CLONE(clone, skb), these variables
would obscure the arguments that the macro was called with, and the
initializers would be a no-op instead of doing their job (undefined
behavior, by the way, but GCC nicely puts NULL pointers instead).
So simply remove this broken macro and leave users to simply call
"DSA_SKB_CB(skb)->clone = clone" by hand when needed.
There is one functional difference when doing what I just suggested
above: the control block won't be transferred from the original skb into
the clone. Since there's no foreseen need for the control block in the
clone ATM, this is ok.

The sk_buff control block can have any contents on xmit put there by the
stack, so initialization is mandatory, since we are checking its value
after the actual DSA xmit (the tagger may have changed it).
The DSA_SKB_ZERO() macro could have been used for this purpose, but:
- Zeroizing a 48-byte memory region in the hotpath is best avoided.
- It would have triggered a warning with newer compilers since
__dsa_skb_cb contains a structure within a structure, and the {0}
initializer was incorrect for that purpose.
So simply remove the DSA_SKB_ZERO() macro and initialize the
deferred_xmit variable by hand (which should be done for all further
dsa_skb_cb variables which need initialization - currently none - to
avoid the performance penalty).

Currently virtio-ccw devices do not work if the device has
VIRTIO_F_IOMMU_PLATFORM. In future we do want to support DMA API with
virtio-ccw.
Let us do the plumbing, so the feature VIRTIO_F_IOMMU_PLATFORM works
with virtio-ccw.
Let us also switch from legacy avail/used accessors to the DMA aware
ones (even if it isn't strictly necessary), and remove the legacy
accessors (we were the last users).

The commit 2a2d1382fe9d ("virtio: Add improved queue allocation API")
establishes a new way of allocating virtqueues (as a part of the effort
that taught DMA to virtio rings).
In the future we will want virtio-ccw to use the DMA API as well.
Let us switch from the legacy method of allocating virtqueues to
vring_create_virtqueue() as the first step into that direction.
