Martin Kaiser 039980de89 hwrng: nomadik - keep clock enabled while hwrng is registered
The nomadik driver uses devres to register itself with the hwrng core,
the driver will be unregistered from hwrng when its device goes out of
scope. This happens after the driver's remove function is called.

However, nomadik's clock is disabled in the remove function. There's a
short timeframe where nomadik is still registered with the hwrng core
although its clock is disabled. I suppose the clock must be active to
access the hardware and serve requests from the hwrng core.

Switch to devm_clk_get_enabled and let devres disable the clock and
unregister the hwrng. This avoids the race condition.

Damian Muszynski bec61a294d crypto: qat - add heartbeat counters check
A firmware update for QAT GEN2 changed the format of a data
structure used to report the heartbeat counters.

To support all firmware versions, extend the heartbeat logic
with an algorithm that detects the number of counters returned
by firmware. The algorithm detects the number of counters to
be used (and size of the corresponding data structure) by the
comparison the expected size of the data in memory, with the data
which was written by the firmware.

Firmware detection is done one time during the first read of heartbeat
debugfs file to avoid increasing the time needed to load the module.

Damian Muszynski 359b84f8db crypto: qat - add heartbeat feature
Under some circumstances, firmware in the QAT devices could become
unresponsive. The Heartbeat feature provides a mechanism to detect
unresponsive devices.

The QAT FW periodically writes to memory a set of counters that allow
to detect the liveness of a device. This patch adds logic to enable
the reporting of those counters, analyze them and report if a device
is alive or not.

In particular this adds
  (1) heartbeat enabling, reading and detection logic
  (2) reporting of heartbeat status and configuration via debugfs
  (3) documentation for the newly created sysfs entries
  (4) configuration of FW settings related to heartbeat, e.g. tick period
  (5) logic to convert time in ms (provided by the user) to clock ticks

This patch introduces a new folder in debugfs called heartbeat with the
following attributes:
 - status
 - queries_sent
 - queries_failed
 - config

All attributes except config are reading only. In particular:
 - `status` file returns 0 when device is operational and -1 otherwise.
 - `queries_sent` returns the total number of heartbeat queries sent.
 - `queries_failed` returns the total number of heartbeat queries failed.
 - `config` allows to adjust the frequency at which the firmware writes
   counters to memory. This period is given in milliseconds and it is
   fixed for GEN4 devices.

The QAT hardware does not expose a mechanism to report its clock
frequency. This is required to implement the Heartbeat feature.

Add a clock measuring algorithm that estimates the frequency by
comparing the internal timestamp counter incremented by the firmware
with the time measured by the kernel.
The frequency value is only used internally and not exposed to

Damian Muszynski fd77d8da1f crypto: qat - add internal timer for qat 4xxx
The power management feature in QAT 4xxx devices can disable clock
sources used to implement timers. Because of that, the firmware needs to
get an external reliable source of time.

Add a kernel delayed work that periodically sends an event to the
firmware. This is triggered every 200ms. At each execution, the driver
sends a sync request to the firmware reporting the current timestamp
counter value.

This is a pre-requisite for enabling the heartbeat, telemetry and
rate limiting features.

Mario Limonciello 15f8aa7bb3 crypto: ccp - Add unit tests for dynamic boost control
Interacting with dynamic boost control messages requires the caller
to supply a signature. To allow validation of individual dynamic
boost control components, introduce a set of tests that can be run.

The tests can be run in 3 distinct different environments, and so
certain tests will be skipped depending on the environment.

1. Systems that do not support DBC.
2. Production systems that support DBC but are secured silicon.
3. Pre-production systems that support DBC but are unsecured silicon.

Unsecured silicon does not validate the signature, and so this allows
testing more of the state machine and functionality.

Chang S. Bae 74c6df413f crypto: x86/aesni - Align the address before aes_set_key_common()
aes_set_key_common() performs runtime alignment to the void *raw_ctx
pointer. This facilitates consistent access to the 16byte-aligned
address during key extension.

However, the alignment is already handlded in the GCM-related setkey
functions before invoking the common function. Consequently, the
alignment in the common function is unnecessary for those functions.

To establish a consistent approach throughout the glue code, remove
the aes_ctx() call from its current location. Instead, place it at
each call site where the runtime alignment is currently absent.

Linus Torvalds c192ac7357 MAINTAINERS 2: Electric Boogaloo
We just sorted the entries and fields last release, so just out of a
perverse sense of curiosity, I decided to see if we can keep things
ordered for even just one release.

The answer is "No. No we cannot".

I suggest that all kernel developers will need weekly training sessions,
involving a lot of Big Bird and Sesame Street.  And at the yearly
maintainer summit, we will all sing the alphabet song together.

I doubt I will keep doing this.  At some point "perverse sense of
curiosity" turns into just a cold dark place filled with sadness and
despair.

Linus Torvalds e3da8db055 A single fix for the mechanism to park CPUs with an INIT IPI.
On shutdown or kexec, the kernel tries to park the non-boot CPUs with an
 INIT IPI. But the same code path is also used by the crash utility. If the
 CPU which panics is not the boot CPU then it sends an INIT IPI to the boot
 CPU which resets the machine. Prevent this by validating that the CPU which
 runs the stop mechanism is the boot CPU. If not, leave the other CPUs in
 HLT.

Lockdep is certainly right to complain about

  (&vma->vm_lock->lock){++++}-{3:3}, at: vma_start_write+0x2d/0x3f
                 but task is already holding lock:
  (&mapping->i_mmap_rwsem){+.+.}-{3:3}, at: mmap_region+0x4dc/0x6db

Invert those to the usual ordering.
