A large increase in the maximum number of processes. Or did I misinterpret?

Factor out perf_prepare_dump_data() so that the same logic is used for
dumping stack data as other types, such as TLS.
Slightly refactor perf_sample_ustack_size() to perf_sample_dump_size().
Move reg checks up into perf_ustack_task_size() since the task size
must now be calculated before preparing
We now have two user dump sources (stack and tls). Both are doing the
same logic to ensure the user dump ABI output is properly handled. The
only difference is one gets the address within the method, and the other
is passed the address.
Add perf_output_sample_udump() and utilize it for both stack
Now that perf supports TLS dumps, x86-64 can provide the details for how
to get TLS data for user threads.
Enable HAVE_PERF_USER_TLS_DUMP Kconfig only for x86-64. I do not have
access to x86 to validate 32-bit.
Utilize mmap_is_ia32() to determine 32/64 bit threads. Use fsbase for
64-bit and gsbas
In the Open Telemetry profiling SIG [1], we are trying to find a way to
grab a tracing association quickly on a per-sample basis. The team at
Elastic has a bespoke way to do this [2], however, I'd like to see a
more general way to achieve this. The folks I've been talking with seem
open to the idea
When samples are generated, there is no way via the perf_event ABI to
fetch per-thread data. This data is very useful in tracing scenarios
that involve correlation IDs, such as OpenTelemetry. They are also
useful for tracking per-thread performance details directly within a
cooperating user process

On the time to free xbc memory, memblock has handed over memory to buddy
allocator. So it doesn't make sense to free memory back to memblock.
memblock_free() called by xbc_exit() even causes UAF bugs on architectures
with CONFIG_ARCH_KEEP_MEMBLOCK disabled like x86. Following KA

There is a space at the end of extra_init_args. In the current logic,
copying extra_init_args to saved_command_line will cause extra spaces
in saved_command_line here or there. Remove the trailing space from
extra_init_args to make the string in saved_command_line look more perfect.
