The ipc code uses the equivalent of
rcu_read_lock();
kfree_rcu(a, rcu);
if (a->deleted) {
rcu_read_unlock();

Is this safe, or is dereferencing "a" after having called call_rcu()

Subject: [PA
This patch adds an additional property in the device tree for adjusting the
delay between a rising edge on PD_SCK until data is ready on DOUT.
This is necessary because of parasitic capacities on different systems.
In the last patch there is a fix of dtc warning if someone is using the
given exam
On a system with parasitic capacities it turned out that DOUT is not ready
after 100 ns after PD_SCK has raised. A measurement showed almost 1000 ns
until DOUT has reached its correct value.
With this patch its now possible to wait until data is ready.
The wait time should not be higher than the
Add clock-frequency property for hx711 ADC
This is the frequency of PD_SCK. It affects only the high value duration
since low value duration is not relevant and we are not able to switch
faster than the minimum duration specified.
After PD_SCK goes high DOUT is read just before PD_SCK goes down a
device tree compiler (dtc) gives a warning if a device node has "@" with a
following number as it's name but no reg property.
fix the example in the documentation of avia,hx711 to conform to dtc
behavior

A new control bit(bit 29) in the TEST_CTRL MSR will be introduced
to enable detection of split locks.
When bit 29 of the TEST_CTRL(33H) MSR is set, the processor
causes an #AC exception to be issued instead of suppressing LOCK on
bus(during split lock access). A previous control bit (bit 31)

These patches switch nios2 boot time memory allocators from bootmem to
memblock + no_bootmem.
As nios2 uses fdt, the conversion is pretty much about actually using the
existing fdt infrastructure for the early memory management.
The first patch in the series is not strictly related to nios2. It's
Memory region size is rounded down to page boundary and with sub-page
region it becomes 0 and there is no point to add an empty region.
Moreover, when the base is less than PAGE_SIZE we get a bogus size as
(base + size - 1) evaluates to -1.
The commit 8cccffc52694 ("of: check for size < 0 after ro
Remove bootmem bitmap initialization and replace reserve_bootmem() with
memblock_reserve().

Use device_get_match_data API to simplify access to driver data.
Let acpi_device_id table entries point to the same driver data as
of_device_id table entries and uniquify access to driver data by using
device_get_match_data API. Remove unused i2c_device_id .driver_data

When trying to instantiate a st_accel_i2c device from an ACPI based
system, I ran into some problems:
For my device, there is no ACPI match table entry, so rather than
creating /allocating a new ACPI HID for the device, I wanted to use an
existing DT table compatible entry via creating an ACPI_DT_

To avoid the below build warning message,
