Stop Endpoint command on LINK TRB with TC bit set to 1 causes that
internal cycle bit can have incorrect state after command complete.
In consequence empty transfer ring can be incorrectly detected
when EP is resumed.
NOP TRB before LINK TRB avoid such scenario. Stop Endpoint command
is then on NOP TRB and internal cycle bit is not changed and have
correct value.

The i915 driver generates sysfs entries for each engine of the
GPU in /sys/class/drm/cardX/engines/.
The process is straightforward: we loop over the UABI engines and
for each one, we:
- Create the object.
- Create basic files.
- If the engine supports timeslicing, create timeslice duration files.
- If the engine supports preemption, create preemption-related files.
- Create default value files.
Currently, if any of these steps fail, the process stops, and no
further sysfs files are created.
However, it's not necessary to stop the process on failure.
Instead, we can continue creating the remaining sysfs files for
the other engines. Even if some files fail to be created, the
list of engines can still be retrieved by querying i915.

These errors happen when MVC device, which is a child of AHUB
device, tries to access its device registers. This happens as
part of call tegra210_mvc_reset_vol_settings() in MVC device
probe().
The root cause of this problem is, the child MVC device gets
probed before the AHUB clock gets enabled. The AHUB clock is
enabled in runtime PM resume of parent AHUB device and due to
the wrong sequence of pm_runtime_enable() in AHUB driver,
runtime PM resume doesn't happen for AHUB device when MVC makes
register access.
Fix this by calling pm_runtime_enable() for parent AHUB device
before of_platform_populate() in AHUB driver. This ensures that
clock becomes available when MVC makes register access.

Currently on a very large system with 1780 CPUs, hv_acpi_init() takes
around 3 seconds to complete. This is because of sequential synic
initialization for each CPU performed by hv_synic_init().
Schedule these tasks parallelly so that each CPU executes hv_synic_init()
in parallel to take full advantage of multiple CPUs.
This solution saves around 2 seconds of boot time on a 1780 CPU system,
which is around 66% improvement in the existing logic.

====================
Support bpf_kptr_xchg into local kptr
This revision adds substaintial changes to patch 2 to support structures
with kptr as the only special btf type. The test is split into
local_kptr_stash and task_kfunc_success to remove dependencies on
bpf_testmod that would break veristat results.
This series allows stashing kptr into local kptr. Currently, kptrs are
only allowed to be stashed into map value with bpf_kptr_xchg(). A
motivating use case of this series is to enable adding referenced kptr to
bpf_rbtree or bpf_list by using allocated object as graph node and the
storage of referenced kptr. For example, a bpf qdisc [0] enqueuing a
referenced kptr to a struct sk_buff* to a bpf_list serving as a fifo:
struct skb_node {
struct sk_buff __kptr *skb;
struct bpf_list_node node;
};
private(A) struct bpf_spin_lock fifo_lock;
private(A) struct bpf_list_head fifo __contains(skb_node, node);
/* In Qdisc_ops.enqueue */
struct skb_node *skbn;
skbn = bpf_obj_new(typeof(*skbn));
if (!skbn)
goto drop;
/* skb is a referenced kptr to struct sk_buff acquired earilier
* but not shown in this code snippet.
*/
skb = bpf_kptr_xchg(&skbn->skb, skb);
if (skb)
/* should not happen; do something below releasing skb to
* satisfy the verifier */
...
bpf_spin_lock(&fifo_lock);
bpf_list_push_back(&fifo, &skbn->node);
bpf_spin_unlock(&fifo_lock);
The implementation first searches for BPF_KPTR when generating program
BTF. Then, we teach the verifier that the detination argument of
bpf_kptr_xchg() can be local kptr, and use the btf_record in program BTF
to check against the source argument.
This series is mostly developed by Dave, who kindly helped and sent me
the patchset. The selftests in bpf qdisc (WIP) relies on this series to
work.
