There are a lot of platforms that have not seen any interesting code
changes in the past five years or more.
I made a list and asked around which ones are no longer in use [1], and
received confirmation about six ARM platforms and the TI C6x architecture
that have all reached the end of their life upstream, with no known
users remaining:
- efm32 -- added in 2011, first Cortex-M, no notable changes after 2013
- picoxcell -- added in 2011, abandoned after 2012 acquisition
- prima2 -- added in 20111, no notable changes since 2015
- tango -- added in 2015, sporadic changes until 2017, but abandoned
- u300 -- added in 2009, no notable changes since 2013
- zx --added in 2015 for both 32, 2017 for 64 bit, no notable changes
- arch/c6x -- added in 2011, but work stalled soon after that
A number of other platforms on the original list turned out to still
have users. In some cases there are out-of-tree patches and users
that plan to contribute them in the future, in other cases the code
is complete and works reliably.

After switching to non-RCU mode, we want nd->depth to match the number
of entries in nd->stack[] that need eventual path_put().
legitimize_links() takes care of that on failures; unfortunately,
failure exits added for LOOKUP_CACHED do not.
We could add the logics for that into those failure exits, both in
try_to_unlazy() and in try_to_unlazy_next(), but since both checks
are immediately followed by legitimize_links() and there's no calls
of legitimize_links() other than those two... It's easier to
move the check (and required handling of nd->depth on failure) into
legitimize_links() itself.
[caught by Jens: ... and since we are zeroing ->depth here, we need
to do drop_links() first]

Commit 36dadef23f ("kprobes: Init kprobes in early_initcall")
moved the kprobe setup in early_initcall(), which includes kprobe
jump optimization.
The kprobes jump optimizer involves synchronize_rcu_tasks() which
depends on the ksoftirqd and rcu_spawn_tasks_*(). However, since
those are setup in core_initcall(), kprobes jump optimizer can not
run at the early_initcall().
To avoid this issue, make the kprobe optimization disabled in the
early_initcall() and enables it in subsys_initcall().
Note that non-optimized kprobes is still available after
early_initcall(). Only jump optimization is delayed.

Wrapping the function with DC_FP_START()/DC_FP_END() seems to solve the

The CoreSight testing contains sub cases, e.g. every CPU iterates the
possible conntected sinks and tests the paths between the associated ETM
with the found sink. Besides the per-thread testing, it also contains
system wide testing and snapshot testing.
To easier observe results for the sub cases, this patch introduces a new
function arm_cs_report(), it outputs the result as "PASS" or "FAIL" for
every sub case; and it records the error in the variable "glb_err" which
is used as the final return value when exits the testing.

With the option '-v' for the verbose logs, "perf test" outputs tons of
logs for the CoreSight case, the logs are mainly introduced by the
decoding. And it outputs some trivial info from "perf record" command
and there have debugging info for CPU number and device name when
iterates between ETMs and sinks.
For a neat output format, this patch redirects the output logs to
"/dev/null", thus can avoid to flood logs. And it removes the redundant
log for CPU number and device name, which have already printed out the
relevant info in the function record_touch_file().

The PIP packet NR (non-root) flag indicates whether or not a virtual
machine is being traced (NR=1 => VM). Add support for tracking its value.
In particular note that the PIP packet (outside of PSB+) will be
associated with a TIP packet from which address the NR value takes
effect. At that point, there is a branch from_ip, to_ip with
corresponding from_nr and to_nr.
In the event of VM-Entry failure, there should still PIP and TIP packets
that can be followed in the same way.
Also note that this assumes that a host VMM is not employing VMX controls
that affect Intel PT, e.g. to hide the host from a guest using Intel PT.
