16b1936ae6 lib/rbtree: add random seed 
Current test use pseudo rand function with fixed seed, which means the
test data is the same pattern each time.

Add random seed parameter to randomize the test.

4164e1525d lib/rbtree: enable userland test suite for rbtree related data structure 
Patch series "lib/interval_tree: add some test cases and cleanup", v2.

Since rbtree/augmented tree/interval tree share similar data structure,
besides new cases for interval tree, this patch set also does cleanup for
others.


This patch (of 7):

Currently we have some tests for rbtree related data structure, e.g. 
rbtree, augmented rbtree, interval tree, in lib/ as kernel module.

To facilitate the test and debug for those fundamental data structure,
this patch enable those tests in userland.

bc2f19d653 checkpatch: describe --min-conf-desc-length 
Neither the warning nor the help message gives any hint on the unit for
length: Could be meters, inches, bytes, characters or ...  lines.

Extend the output of `--help` to name the unit "lines" and the default:
-  --min-conf-desc-length=n   set the min description length, if shorter, warn
+  --min-conf-desc-length=n   set the minimum description length for config symbols
+                             in lines, if shorter, warn (default 4)

Include the minimum number of lines as other error messages already do:
- WARNING: please write a help paragraph that fully describes the config symbol
+ WARNING: please write a help paragraph that fully describes the config symbol with at least 4 lines

8a56f26607 signal: avoid clearing TIF_SIGPENDING in recalc_sigpending() if unset 
Clearing is an atomic op and the flag is not set most of the time.

When creating and destroying threads in the same process with the pthread
family, the primary bottleneck is calls to sigprocmask which take the
process-wide sighand lock.

Avoiding the atomic gives me a 2% bump in start/teardown rate at 24-core
scale.

e0349c46cb scripts/gdb/linux/symbols.py: address changes to module_sect_attrs 
When loading symbols from kernel modules we used to iterate
from 0 to module_sect_attrs::nsections, in order to
retrieve their name and address.

However module_sect_attrs::nsections has been removed from
the struct by a previous commit.

Re-arrange the iteration by accessing all items in
module_sect_attrs::grp::bin_attrs[] until NULL is found
(it's a NULL terminated array).

At the same time the symbol address cannot be extracted
from module_sect_attrs::attrs[]::address anymore because
it has also been deleted. Fetch it from
module_sect_attrs::grp::bin_attrs[]::private as described
in 4b2c11e4aa.

6cf828d2fb nvme: convert timeouts to secs_to_jiffies() 
Commit b35108a51c ("jiffies: Define secs_to_jiffies()") introduced
secs_to_jiffies().  As the value here is a multiple of 1000, use
secs_to_jiffies() instead of msecs_to_jiffies() to avoid the
multiplication

15c200eaf5 coccinelle: misc: secs_to_jiffies: Patch expressions too 
Patch series "Converge on using secs_to_jiffies() part two", v3.

This is the second series that converts users of msecs_to_jiffies() that
either use the multiply pattern of either of:
- msecs_to_jiffies(N*1000) or
- msecs_to_jiffies(N*MSEC_PER_SEC)

where N is a constant or an expression, to avoid the multiplication.

The conversion is made with Coccinelle with the secs_to_jiffies() script
in scripts/coccinelle/misc.  Attention is paid to what the best change can
be rather than restricting to what the tool provides.


This patch (of 16):

Teach the script to suggest conversions for timeout patterns where the
arguments to msecs_to_jiffies() are expressions as well.

4022918876 scripts/gdb: add $lx_per_cpu_ptr() 
We currently have $lx_per_cpu() which works fine for stuff that kernel
code would access via per_cpu().  But this doesn't work for stuff that
kernel code accesses via per_cpu_ptr():

(gdb) p $lx_per_cpu(node_data[1].node_zones[2]->per_cpu_pageset)
Cannot access memory at address 0xffff11105fbd6c28

This is because we take the address of the pointer and use that as the
offset, instead of using the stored value.

Add a GDB version that mirrors the kernel API, which uses the pointer
value.

To be consistent with per_cpu_ptr(), we need to return the pointer value
instead of dereferencing it for the user.  Therefore, move the existing
dereference out of the per_cpu() Python helper and do that only in the
$lx_per_cpu() implementation.

5e40d0d196 reboot: retire hw_protection_reboot and hw_protection_shutdown helpers 
The hw_protection_reboot and hw_protection_shutdown functions mix
mechanism with policy: They let the driver requesting an emergency action
for hardware protection also decide how to deal with it.

This is inadequate in the general case as a driver reporting e.g.  an
imminent power failure can't know whether a shutdown or a reboot would be
more appropriate for a given hardware platform.

With the addition of the hw_protection parameter, it's now possible to
configure at runtime the default emergency action and drivers are expected
to use hw_protection_trigger to have this parameter dictate policy.

As no current users of either hw_protection_shutdown or
hw_protection_shutdown helpers remain, remove them, as not to tempt driver
authors to call them.

Existing users now either defer to hw_protection_trigger or call
__hw_protection_trigger with a suitable argument directly when they have
inside knowledge on whether a reboot or shutdown would be more
appropriate.

941a07cad2 thermal: core: allow user configuration of hardware protection action 
In the general case, we don't know which of system shutdown or reboot is
the better action to take to protect hardware in an emergency situation. 
We thus allow the policy to come from the device-tree in the form of an
optional critical-action OF property, but so far there was no way for the
end user to configure this.

With recent addition of the hw_protection parameter, the user can now
choose a default action for the case, where the driver isn't fully sure
what's the better course of action.

Let's make use of this by passing HWPROT_ACT_DEFAULT in absence of the
critical-action OF property.

As HWPROT_ACT_DEFAULT is shutdown by default, this introduces no
functional change for users, unless they start using the new parameter.

738b785693 dt-bindings: thermal: give OS some leeway in absence of critical-action 
An operating system may allow its user to configure the action to be
undertaken on critical overtemperature events.

However, the bindings currently mandate an absence of the critical-action
property to be equal to critical-action = "shutdown", which would mean any
differing user configuration would violate the bindings.

Resolve this by documenting the absence of the property to mean that the
OS gets to decide.

cd9beb9eb3 platform/chrome: cros_ec_lpc: prepare for hw_protection_shutdown removal 
In the general case, a driver doesn't know which of system shutdown or
reboot is the better action to take to protect hardware in an emergency
situation.  For this reason, hw_protection_shutdown is going to be removed
in favor of hw_protection_trigger, which defaults to shutdown, but may be
configured at kernel runtime to be a reboot instead.

The ChromeOS EC situation is different as we do know that shutdown is the
correct action as the EC is programmed to force reset after the short
period, thus replace hw_protection_shutdown with __hw_protection_trigger
with HWPROT_ACT_SHUTDOWN as argument to maintain the same behavior.

No functional change.

b15388a2f0 regulator: allow user configuration of hardware protection action 
When the core detects permanent regulator hardware failure or imminent
power failure of a critical supply, it will call hw_protection_shutdown in
an attempt to do a limited orderly shutdown followed by powering off the
system.

This doesn't work out well for many unattended embedded systems that don't
have support for shutdown and that power on automatically when power is
supplied:

  - A brief power cycle gets detected by the driver
  - The kernel powers down the system and SoC goes into shutdown mode
  - Power is restored
  - The system remains oblivious to the restored power
  - System needs to be manually power cycled for a duration long enough
    to drain the capacitors

Allow users to fix this by calling the newly introduced
hw_protection_trigger() instead: This way the hw_protection commandline or
sysfs parameter is used to dictate the policy of dealing with the
regulator fault.

e016173f65 reboot: add support for configuring emergency hardware protection action 
We currently leave the decision of whether to shutdown or reboot to
protect hardware in an emergency situation to the individual drivers.

This works out in some cases, where the driver detecting the critical
failure has inside knowledge: It binds to the system management controller
for example or is guided by hardware description that defines what to do.

In the general case, however, the driver detecting the issue can't know
what the appropriate course of action is and shouldn't be dictating the
policy of dealing with it.

Therefore, add a global hw_protection toggle that allows the user to
specify whether shutdown or reboot should be the default action when the
driver doesn't set policy.

This introduces no functional change yet as hw_protection_trigger() has no
callers, but these will be added in subsequent commits.

06eaeaee5b docs: thermal: sync hardware protection doc with code 
Originally, the thermal framework's only hardware protection action was to
trigger a shutdown.  This has been changed a little over a year ago to
also support rebooting as alternative hardware protection action.

Update the documentation to reflect this.

bbf0ec4f57 reboot: reboot, not shutdown, on hw_protection_reboot timeout 
hw_protection_shutdown() will kick off an orderly shutdown and if that
takes longer than a configurable amount of time, an emergency shutdown
will occur.

Recently, hw_protection_reboot() was added for those systems that don't
implement a proper shutdown and are better served by rebooting and having
the boot firmware worry about doing something about the critical
condition.

On timeout of the orderly reboot of hw_protection_reboot(), the system
would go into shutdown, instead of reboot.  This is not a good idea, as
going into shutdown was explicitly not asked for.

Fix this by always doing an emergency reboot if hw_protection_reboot() is
called and the orderly reboot takes too long.

318f05a057 reboot: replace __hw_protection_shutdown bool action parameter with an enum 
Patch series "reboot: support runtime configuration of emergency
hw_protection action", v3.

We currently leave the decision of whether to shutdown or reboot to
protect hardware in an emergency situation to the individual drivers.

This works out in some cases, where the driver detecting the critical
failure has inside knowledge: It binds to the system management controller
for example or is guided by hardware description that defines what to do.

This is inadequate in the general case though as a driver reporting e.g. 
an imminent power failure can't know whether a shutdown or a reboot would
be more appropriate for a given hardware platform.

To address this, this series adds a hw_protection kernel parameter and
sysfs toggle that can be used to change the action from the shutdown
default to reboot.  A new hw_protection_trigger API then makes use of this
default action.

My particular use case is unattended embedded systems that don't have
support for shutdown and that power on automatically when power is
supplied:

  - A brief power cycle gets detected by the driver
  - The kernel powers down the system and SoC goes into shutdown mode
  - Power is restored
  - The system remains oblivious to the restored power
  - System needs to be manually power cycled for a duration long enough
    to drain the capacitors

With this series, such systems can configure the kernel with
hw_protection=reboot to have the boot firmware worry about critical
conditions.


This patch (of 12):

Currently __hw_protection_shutdown() either reboots or shuts down the
system according to its shutdown argument.

To make the logic easier to follow, both inside __hw_protection_shutdown
and at caller sites, lets replace the bool parameter with an enum.

This will be extra useful, when in a later commit, a third action is added
to the enumeration.

No functional change.

5f01a22c5b ucount: use RCU for ucounts lookups 
The ucounts element is looked up under ucounts_lock.  This can be
optimized by using RCU for a lockless lookup and return and element if the
reference can be obtained.

Replace hlist_head with hlist_nulls_head which is RCU compatible.  Let
find_ucounts() search for the required item within a RCU section and
return the item if a reference could be obtained.  This means
alloc_ucounts() will always return an element (unless the memory
allocation failed).  Let put_ucounts() RCU free the element if the
reference counter dropped to zero.

328152e677 ucount: replace get_ucounts_or_wrap() with atomic_inc_not_zero() 
get_ucounts_or_wrap() increments the counter and if the counter is
negative then it decrements it again in order to reset the previous
increment.  This statement can be replaced with atomic_inc_not_zero() to
only increment the counter if it is not yet 0.

This simplifies the get function because the put (if the get failed) can
be removed.  atomic_inc_not_zero() is implement as a cmpxchg() loop which
can be repeated several times if another get/put is performed in parallel.
This will be optimized later.

Increment the reference counter only if not yet dropped to zero.

8c6bbda879 rcu: provide a static initializer for hlist_nulls_head 
Patch series "ucount: Simplify refcounting with rcuref_t".

I noticed that the atomic_dec_and_lock_irqsave() in put_ucounts() loops
sometimes even during boot.  Something like 2-3 iterations but still. 
This series replaces the refcounting with rcuref_t and adds a RCU lookup.

This allows a lockless lookup in alloc_ucounts() if the entry is available
and a cmpxchg()less put of the item.


This patch (of 4):

Provide a static initializer for hlist_nulls_head so that it can be used
in statically defined data structures.

Now that the only user of the macro depends on DEBUG_ZLIB config, GCC
warns about unused macro if the library is built with W=2 against
defconfig.  So drop it for good.
