The Wacom driver maps the HID_DG_TWIST usage to ABS_Z (rather than ABS_RZ)
for historic reasons. When the code to support twist was introduced in
commit 50066a042d ("HID: wacom: generic: Add support for height, tilt,
and twist usages"), we were careful to write it in such a way that it had
HID calculate the resolution of the twist axis assuming ABS_RZ instead
(so that we would get correct angular behavior). This was broken with
the introduction of commit 08a46b4190 ("HID: wacom: Set a default
resolution for older tablets"), which moved the resolution calculation
to occur *before* the adjustment from ABS_Z to ABS_RZ occurred.
This commit moves the calculation of resolution after the point that
we are finished setting things up for its proper use.

And it is completely unclear why register_for_each_vma() takes mmap_lock

avoid the following race:
- A task T hits the bp installed by uprobe and calls
find_active_uprobe()
- uprobe_unregister() removes this uprobe/bp
- T calls find_uprobe() which returns NULL
- another uprobe_register() installs the bp at the same address
- T calls is_trap_at_addr() which returns true
- T returns to handle_swbp() and gets SIGTRAP.

When tracing user functions with uprobe functionality, it's common to
install the probe (e.g., a BPF program) at the first instruction of the
function. This is often going to be `push %rbp` instruction in function
preamble, which means that within that function frame pointer hasn't
been established yet. This leads to consistently missing an actual
caller of the traced function, because perf_callchain_user() only
records current IP (capturing traced function) and then following frame
pointer chain (which would be caller's frame, containing the address of
caller's caller).
So when we have target_1 -> target_2 -> target_3 call chain and we are
tracing an entry to target_3, captured stack trace will report
target_1 -> target_3 call chain, which is wrong and confusing.
This patch proposes a x86-64-specific heuristic to detect `push %rbp`
(`push %ebp` on 32-bit architecture) instruction being traced. Given
entire kernel implementation of user space stack trace capturing works
under assumption that user space code was compiled with frame pointer
register (%rbp/%ebp) preservation, it seems pretty reasonable to use
this instruction as a strong indicator that this is the entry to the
function. In that case, return address is still pointed to by %rsp/%esp,
so we fetch it and add to stack trace before proceeding to unwind the
rest using frame pointer-based logic.
We also check for `endbr64` (for 64-bit modes) as another common pattern
for function entry, as suggested by Josh Poimboeuf. Even if we get this
wrong sometimes for uprobes attached not at the function entry, it's OK
because stack trace will still be overall meaningful, just with one
extra bogus entry. If we don't detect this, we end up with guaranteed to
be missing caller function entry in the stack trace, which is worse
overall.

This change allows events to use PERF_SAMPLE_READ with inherit
so long as PERF_SAMPLE_TID is also set. This enables sample based
profiling of a group of counters over a hierarchy of processes or
threads. This is useful, for example, for collecting per-thread
counters/metrics, event based sampling of multiple counters as a unit,
access to the enabled and running time when using multiplexing and so
on.
Prior to this, users were restricted to either collecting aggregate
statistics for a multi-threaded/-process application (e.g. with
"perf stat"), or to sample individual threads, or to profile the entire
system (which requires root or CAP_PERFMON, and may produce much more
data than is required). Theoretically a tool could poll for or otherwise
monitor thread/process creation and construct whatever events the user
is interested in using perf_event_open, for each new thread or process,
but this is racy, can lead to file-descriptor exhaustion, and ultimately
just replicates the behaviour of inherit, but in userspace.
This configuration differs from inherit without PERF_SAMPLE_READ in that
the accumulated event count, and consequently any sample (such as if
triggered by overflow of sample_period) will be on a per-thread rather
than on an aggregate basis.
The meaning of read_format::value field of both PERF_RECORD_READ and
PERF_RECORD_SAMPLE is changed such that if the sampled event uses this
new configuration then the values reported will be per-thread rather
than the global aggregate value. This is a change from the existing
semantics of read_format (where PERF_SAMPLE_READ is used without
inherit), but it is necessary to expose the per-thread counter values,
and it avoids reinventing a separate "read_format_thread" field that
otherwise replicates the same behaviour. This change should not break
existing tools, since this configuration was not previously valid and
was rejected by the kernel. Tools that opt into this new mode will need
to account for this when calculating the counter delta for a given
sample. Tools that wish to have both the per-thread and aggregate value
can perform the global aggregation themselves from the per-thread
values.
The change to read_format::value does not affect existing valid
perf_event_attr configurations, nor does it change the behaviour of
calls to "read" on an event descriptor. Both continue to report the
aggregate value for the entire thread/process hierarchy. The difference
between the results reported by "read" and PERF_RECORD_SAMPLE in this
new configuration is justified on the basis that it is not (easily)
possible for "read" to target a specific thread (the caller only has
the fd for the original parent event).
