bc1f40df1b reserved_memory: change print of all reserved memory [1/1]
PD#SWPL-16049

Problem:
When boot, print information of all reserved memory is not nice
for reading.

Solution:
Change print format of reserved memory like:

ec1e1e3c0f suspend: fix freeze hangup which caused by insmod [1/1]
PD#TV-10472

Problem:
When system on, enter freeze mode lead to flush deferd probe.
Init.rc also run insmod in parallel, if insmod task
atomic_inc(&probe_count), and this task is freezed,
deadlock happends.

Solution:
Move flush deferd probe action before freeze task

3c34d4e34a PM / wakeup: Rework wakeup source timer cancellation
commit 1fad17fb1b upstream.

If wakeup_source_add() is called right after wakeup_source_remove()
for the same wakeup source, timer_setup() may be called for a
potentially scheduled timer which is incorrect.

To avoid that, move the wakeup source timer cancellation from
wakeup_source_drop() to wakeup_source_remove().

Moreover, make wakeup_source_remove() clear the timer function after
canceling the timer to let wakeup_source_not_registered() treat
unregistered wakeup sources in the same way as the ones that have
never been registered.

997e954bb0 BACKPORT:dma-buf/fence: Fix lock inversion within dma-fence-array
Ages ago Rob Clark noted,

"Currently with fence-array, we have a potential deadlock situation.  If
we fence_add_callback() on an array-fence, the array-fence's lock is
acquired first, and in it's ->enable_signaling() callback, it will install
cbs on it's array-member fences, so the array-member's lock is acquired
second.

But in the signal path, the array-member's lock is acquired first, and
the array-fence's lock acquired second."

Rob proposed either extensive changes to dma-fence to unnest the
fence-array signaling, or to defer the signaling onto a workqueue. This
is a more refined version of the later, that should keep the latency
of the fence signaling to a minimum by using an irq-work, which is
executed asap.

6989d4079d PM / OPP: Update voltage in case freq == old_freq
commit c5c2a97b3a upstream.

This commit fixes a rare but possible case when the clk rate is updated
without update of the regulator voltage.

At boot up, CPUfreq checks if the system is running at the right freq. This
is a sanity check in case a bootloader set clk rate that is outside of freq
table present with cpufreq core. In such cases system can be unstable so
better to change it to a freq that is preset in freq-table.

The CPUfreq takes next freq that is >= policy->cur and this is our
target_freq that needs to be set now.

dev_pm_opp_set_rate(dev, target_freq) checks the target_freq and the
old_freq (a current rate). If these are equal it returns early. If not,
it searches for OPP (old_opp) that fits best to old_freq (not listed in
the table) and updates old_freq (!).

Here, we can end up with old_freq = old_opp.rate = target_freq, which
is not handled in _generic_set_opp_regulator(). It's supposed to update
voltage only when freq > old_freq  || freq > old_freq.

if (freq > old_freq) {
		ret = _set_opp_voltage(dev, reg, new_supply);
[...]
if (freq < old_freq) {
		ret = _set_opp_voltage(dev, reg, new_supply);
		if (ret)

It results in, no voltage update while clk rate is updated.

Example:
freq-table = {
	1000MHz   1.15V
	 666MHZ   1.10V
	 333MHz   1.05V
}
boot-up-freq        = 800MHz   # not listed in freq-table
freq = target_freq  = 1GHz
old_freq            = 800Mhz
old_opp = _find_freq_ceil(opp_table, &old_freq);  #(old_freq is modified!)
old_freq            = 1GHz

4f65ebcffa driver core: Don't ignore class_dir_create_and_add() failure.
commit 84d0c27d62 upstream.

syzbot is hitting WARN() at kernfs_add_one() [1].
This is because kernfs_create_link() is confused by previous device_add()
call which continued without setting dev->kobj.parent field when
get_device_parent() failed by memory allocation fault injection.
Fix this by propagating the error from class_dir_create_and_add() to
the calllers of get_device_parent().

7a2e11e7ba regmap: Correct comparison in regmap_cached
[ Upstream commit 71df179363 ]

The cache pointer points to the actual memory used by the cache, as the
comparison here is looking for the type of the cache it should check
against cache_type.

Fixes: 1ea975cf1e ("regmap: Add a function to check if a regmap register is cached")

24e4dd97af x86/bugs: Expose /sys/../spec_store_bypass
commit c456442cd3 upstream

Add the sysfs file for the new vulerability. It does not do much except
show the words 'Vulnerable' for recent x86 cores.

Intel cores prior to family 6 are known not to be vulnerable, and so are
some Atoms and some Xeon Phi.

It assumes that older Cyrix, Centaur, etc. cores are immune.

cddf0e1ce6 regmap: Fix reversed bounds check in regmap_raw_write()
commit f00e71091a upstream.

We're supposed to be checking that "val_len" is not too large but
instead we check if it is smaller than the max.

The only function affected would be regmap_i2c_smbus_i2c_write() in
drivers/base/regmap/regmap-i2c.c.  Strangely that function has its own
limit check which returns an error if (count >= I2C_SMBUS_BLOCK_MAX) so
it doesn't look like it has ever been able to do anything except return
an error.

f361eb39cd PM / OPP: list_del_rcu should be used in function _remove_opp_dev
list_del_rcu should be used to replace list_del in function _remove_opp_dev,
since the opp is a rcu protected pointer.

Test: for example, on an ARM big.Little platform, the opp_table of big cluster
will be removed when big cluster is removed, which should be implemented in
the cpufreq driver.
Then a stress test that the big cluster is plugged in/out, can test the patch.

1d8c402e0c drivers: base: cacheinfo: fix boot error message when acpi is enabled
commit 55877ef45f upstream.

ARM64 enables both CONFIG_OF and CONFIG_ACPI and the firmware can pass
both ACPI tables and the device tree. Based on the kernel parameter, one
of the two will be chosen. If acpi is enabled, then device tree is not
unflattened.

Currently ARM64 platforms report:
"
	Failed to find cpu0 device node
	Unable to detect cache hierarchy from DT for CPU 0
"
which is incorrect when booting with ACPI. Also latest ACPI v6.1 has no
support for cache properties/hierarchy.

This patch adds check for unflattened device tree and also returns as
"not supported" if ACPI is runtime enabled.

It also removes the reference to DT from the error message as the cache
hierarchy can be detected from the firmware(OF/DT/ACPI)

f5aaa5a283 drivers: base: cacheinfo: fix x86 with CONFIG_OF enabled
commit fac5148257 upstream.

With CONFIG_OF enabled on x86, we get the following error on boot:
"
	Failed to find cpu0 device node
 	Unable to detect cache hierarchy from DT for CPU 0
"
and the cacheinfo fails to get populated in the corresponding sysfs
entries. This is because cache_setup_of_node looks for of_node for
setting up the shared cpu_map without checking that it's already
populated in the architecture specific callback.

In order to indicate that the shared cpu_map is already populated, this
patch introduces a boolean `cpu_map_populated` in struct cpu_cacheinfo
that can be used by the generic code to skip cache_shared_cpu_map_setup.

This patch also sets that boolean for x86.

11ec2df9c0 sysfs/cpu: Add vulnerability folder
commit 87590ce6e3 upstream.

As the meltdown/spectre problem affects several CPU architectures, it makes
sense to have common way to express whether a system is affected by a
particular vulnerability or not. If affected the way to express the
mitigation should be common as well.

Create /sys/devices/system/cpu/vulnerabilities folder and files for
meltdown, spectre_v1 and spectre_v2.

Allow architectures to override the show function.

check, opp table will not be created in platform code,
so cpufreq driver prints the following error message:

cpu cpu0: dev_pm_opp_get_opp_count: OPP table not found (-19)

However, this is not really an error in this case because the
imx6q-cpufreq driver first calls dev_pm_opp_get_opp_count()
and if it fails, it means that platform code does not provide
OPP and then dev_pm_opp_of_add_table() will be called.

In order to avoid such confusing error message, move it to
debug level.

It is up to the caller of dev_pm_opp_get_opp_count() to check its
return value and decide if it will print an error or not.

1db069c057 isa: Prevent NULL dereference in isa_bus driver callbacks
commit 5a244727f4 upstream.

The isa_driver structure for an isa_bus device is stored in the device
platform_data member of the respective device structure. This
platform_data member may be reset to NULL if isa_driver match callback
for the device fails, indicating a device unsupported by the ISA driver.

This patch fixes a possible NULL pointer dereference if one of the
isa_driver callbacks to attempted for an unsupported device. This error
should not occur in practice since ISA devices are typically manually
configured and loaded by the users, but we may as well prevent this
error from popping up for the 0day testers.

7da4cd97f5 PM / wakeirq: report a wakeup_event on dedicated wekup irq
[ Upstream commit 09bb6e9395 ]

There are two reasons for reporting wakeup event when dedicated wakeup
IRQ is triggered:

- wakeup events accounting, so proper statistical data will be
  displayed in sysfs and debugfs;

- there are small window when System is entering suspend during which
  dedicated wakeup IRQ can be lost:

dpm_suspend_noirq()
  |- device_wakeup_arm_wake_irqs()
      |- dev_pm_arm_wake_irq(X)
         |- IRQ is enabled and marked as wakeup source
[1]...
  |- suspend_device_irqs()
     |- suspend_device_irq(X)
	|- irqd_set(X, IRQD_WAKEUP_ARMED);
	   |- wakup IRQ armed

The wakeup IRQ can be lost if it's triggered at point [1]
and not armed yet.

Hence, fix above cases by adding simple pm_wakeup_event() call in
handle_threaded_wake_irq().

2a077f7258 device property: Track owner device of device property
commit 5ab894aee0 upstream.

Deletion of subdevice will remove device properties associated to parent
when they share the same firmware node after commit 478573c93a (driver
core: Don't leak secondary fwnode on device removal).  This was observed
with a driver adding subdevice that driver wasn't able to read device
properties after rmmod/modprobe cycle.

Consider the lifecycle of it:

parent device registration
	ACPI_COMPANION_SET()
	device_add_properties()
		pset_copy_set()
		set_secondary_fwnode(dev, &p->fwnode)
	device_add()

parent probe
	read device properties
	ACPI_COMPANION_SET(subdevice, ACPI_COMPANION(parent))
	device_add(subdevice)

parent remove
	device_del(subdevice)
		device_remove_properties()
			set_secondary_fwnode(dev, NULL);
			pset_free()

Parent device will have its primary firmware node pointing to an ACPI
node and secondary firmware node point to device properties.

ACPI_COMPANION_SET() call in parent probe will set the subdevice's
firmware node to point to the same 'struct fwnode_handle' and the
associated secondary firmware node, i.e. the device properties as the
parent.

When subdevice is deleted in parent remove that will remove those
device properties and attempt to read device properties in next
parent probe call will fail.

Fix this by tracking the owner device of device properties and delete
them only when owner device is being deleted.

a97ca4f780 driver core: platform: Don't read past the end of "driver_override" buffer
commit bf563b01c2 upstream.

When printing the driver_override parameter when it is 4095 and 4094 bytes
long, the printing code would access invalid memory because we need count+1
bytes for printing.

Reject driver_override values of these lengths in driver_override_store().

This is in close analogy to commit 4efe874aac ("PCI: Don't read past the
end of sysfs "driver_override" buffer") from Sasha Levin.

The device_pm_check_callbacks() function doesn't check legacy
->suspend and ->resume callback pointers under the device's
bus type, class and driver, so in some cases it may set the
no_pm_callbacks flag for the device incorrectly and then the
callbacks may be skipped during system suspend/resume, which
shouldn't happen.

5555eb956e driver core: bus: Fix a potential double free
commit 0f9b011d33 upstream.

The .release function of driver_ktype is 'driver_release()'.
This function frees the container_of this kobject.

So, this memory must not be freed explicitly in the error handling path of
'bus_add_driver()'. Otherwise a double free will occur.

1f32e67ada device property: Make dev_fwnode() public
commit e44bb0cbdc upstream.

The function to obtain a fwnode related to a struct device is useful for
drivers that use the fwnode property API: it allows not being aware of the
underlying firmware implementation.
