Fix the absence of warning message and kernel tainting when initializing
drivers from the `drivers/staging` subtree from initcalls (when
configured as built-in).
When such a driver is built as module and the module is loaded, the

Please take in consideration i do not own any qcs404 board

Changes since v1
In commit b022f0c7e404
("tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbols")
it was already done for symbol in __trace_kprobe_create(), but func in
create_local_trace_kprobe() is also valid usage.
Not doing so leads to ENOENT for module_name:symbol_name

pid_list_fill_irq() runs via irq_work.
When CONFIG_PREEMPT_RT is disabled, it would run in irq_context.
so it shouldn't sleep while memory allocation.
Change gfp flags from GFP_KERNEL to GFP_NOWAIT to prevent sleep in
irq_work.

Here we use the hugetlbfs tracepoint to track the call stack. And
the output in trace is as follows:
```
touch-5250[002] . 123.557640: hugetlbfs_alloc_inode: dev = (0,49),
ino = 29897, dir = 24079, mode = 0100644
touch-5250[002] . 123.557650: hugetlbfs_setattr: dev = (0,49),
Here we add some basic tracepoints for debugging hugetlbfs: {alloc, free,
evict}_inode, setattr and fallocate.
v1 can be found at:
https://lore.kernel.org/linux-mm/20240701194906.3a9b6...@gandalf.local.home/T/
Changes since v1:
- Decrease the parameters for setattr tracer suggested by Steve
Add basic tracepoints for {alloc, evict, free}_inode, setattr and
fallocate. These can help users to debug hugetlbfs more conveniently.

This change adds a handler for tdx_hcall in the x86_hyper_runtime type for
VMware hypervisors which will ultimately invoke __tdx_hypercall. The
