The output of perf test and perf test list differ because perf test list
does not display subtests. Correct this behavior and also let perf test
list report subtests.
For example:
$ ./perf test 2>&1 |wc -l

Without this commit:
$ ./perf test list 2>&1 |wc -l

With this commit:
$ ./perf test list 2>&1 |wc -l

Out of thread__find_add_map(..., MAP__FUNCTION, ...), idea here is to
continue removing references to MAP__{FUNCTION,VARIABLE} ahead of
getting both types of symbols in the same rbtree, as various places do
two lookups, looking first at MAP__FUNCTION, then at MAP__VARIABLE.
So thread__find_map() will eventually do just that, and 'struct symbol'
will have the symbol type, for code that cares about that.

Even though we weren't injecting guilty requests to be reset, we could
still fall over the issue of resetting the same request too fast -- where
the GPU refuses to start again. (Although it is interesting to note that
reloading the driver is sufficient, suggesting that we could recover if
we delayed the setup after reset?) Continue to paper over the problem by
adding a small delay by waiting for the engine to idle between tests,
and ensure that the engines are idle before starting the idle tests.

It's possible for userspace to control n. Sanitize n when using it as an
array index.
Note that while it appears that n must be bound to the interval [0,3]
due to the way it is extracted from addr, we cannot guarantee that
compiler transformations (and/or future refactoring) will ensure this is
the case, and given this is a slow path it's better to always perform
the masking.

ceph_con_workfn() validates con->state before calling try_read() and
then try_write(). However, try_read() temporarily releases con->mutex,
notably in process_message() and ceph_con_in_msg_alloc(), opening the
window for ceph_con_close() to sneak in, close the connection and
release con->sock. When try_write() is called on the assumption that
con->state is still valid (i.e. not STANDBY or CLOSED), a NULL sock
gets passed to the networking stack:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000020
IP: selinux_socket_sendmsg+0x5/0x20
Make sure con->state is valid at the top of try_write() and add an
explicit BUG_ON for this, similar to try_read().

We call intel_dp_compute_rate() in intel_dp_compute_config() only to be
able to debug log the link_bw and rate_select parameters; we don't use
the parameters here for anything else. We call intel_dp_compute_rate()
again during link training where we actually need and use the
parameters.
Move the debug logging of link_bw and rate_select to
intel_dp_link_training_clock_recovery(), and clean up the extra
intel_dp_compute_rate() call and extra clutter from the already
overcrowded intel_dp_compute_config().

When the blk-mq inflight implementation was added, /proc/diskstats was
converted to use it, but /sys/block/$dev/inflight was not. Fix it by

In the legacy block case, we increment the counter right after we
allocate the request, not when the driver handles it. In both the legacy
and blk-mq cases, part_inc_in_flight() is called from
blk_account_io_start() right after we've allocated the request. blk-mq
only considers requests started requests as inflight, but this is
inconsistent with the legacy definition and the intention in the code.
This removes the started condition and instead counts all allocated
requests.

- Enable CMA for the framebuffer, and the new TVE200
framebuffer driver and the Ilitek ILI9322 driver for
graphics on the D-Link DIR-685. HIGHMEM support comes in
as part of this.
- Enable networking and the new Cortina Gemini ethernet
driver.
- Enable MDIO over GPIO and the Realtek PHY devices used on
several of these systems.
- Enable I2C over GPIO and SPI over GPIO which is used on
several of these devices.
- Enable the Thermal framework, GPIO fan control and LM75 sensor
adding cooling on the D-Link DNS-313 with no userspace

For ACPI support of the HiSilicon LPC driver we depend
on MFD_CORE config.
Currently the HiSi LPC Kconfig entry does not define this
dependency, so add it.
The reason for depending on MFD_CORE in the driver is
that we model the LPC host as an MFD, in that a platform
device will be created for each device on the bus.
We do this as we need to modify the resources of these
derived platform devices, something which we should not
do to the original devices created in the ACPI scan.

In other places where regmap_read() is used a u32 variable is passed
to store the register read value, so do the same here as well.
regmap API already takes care of endianness, so the usage of u32 is safe.

Sometimes it is useful to see which user opcode bytes RIP points to
when a fault happens: be it to rule out RIP corruption, to dump info
early during boot, when doing core dumps is impossible due to not having
a writable filesystem yet.
Sometimes it is useful if debugging an issue and one doesn't have access
to the executable which caused the fault in order to disassemble it.
That last aspect might have some security implications so
show_unhandled_signals could be revisited for that or a new config option
added.

The code used to iterate byte-by-byte over the bytes around RIP and that
is expensive: disabling pagefaults around it, copy_from_user, etc...
Make it read the whole buffer of OPCODE_BUFSIZE size in one go. Use a
statically allocated 64 bytes buffer so that concurrent show_opcodes()
do not interleave in the output even though in the majority of the cases
it's serialized via die_lock. Except the #PF path which doesn't...
Also, do the PAGE_OFFSET check outside of the function because latter
will be reused in other context.

This was added by
86c4183742 ("[PATCH] i386: add option to show more code in oops reports")
long time ago but experience shows that 64 instruction bytes are plenty
when deciphering an oops. So get rid of it.
Removing it will simplify further enhancements to the opcodes dumping
machinery coming in the following patches.

The majority of the engine state dumping is too voluminous to be useful
outside of a controlled setup, though a few do accompany severe errors.
Keep the debug dumps next to the errors, but hide the others behind a CI
compile flag. This becomes more useful when adding more dumps to latency
sensitive paths.

This patch adds support for the MT7622 AFE which reuses MT2701 driver.
We also introduce the 'struct mt2701_soc_variants' to differentiate
between the SoC generations as there might be other (existing or future)
chips that use the same binding and driver, then being a little more
abstract could help in the long run.

Recent AMD systems support using MWAIT for C1 state. However, MWAIT will
not allow deeper cstates than C1 on current systems.
play_dead() expects to use the deepest state available. The deepest state
available on AMD systems is reached through SystemIO or HALT. If MWAIT is
available, it is preferred over the other methods, so the CPU never reaches
the deepest possible state.
Don't try to use MWAIT to play_dead() on AMD systems. Instead, use CPUIDLE
to enter the deepest state advertised by firmware. If CPUIDLE is not
available then fallback to HALT.
