Hi,
Recently, when I trying to destroy a virtual machine, I came across
a panic. The stack is listed at the end of this mail.
After analyze, I think it is a problem of cpu, it generate an interrupt
of vector 24.
SS/ESP/EFLAGS/CS/RIP are push into stack. and EFLAGS is changed from 0x286
to 0x100

Hi Thomas,
I am sorry, this is the reason why I added Fenghua in SOB list:
I have sent this patch to Fenghua for internal review. After that, I sent it

What is your suggestion to fix? Move Fenghua from "Signed-off-by:" to "Cc:"?
Thank you.

The lpuart of imx7ulp is basically the same as ls1021a. It's also
32 bit width register, but unlike ls1021a, it's little endian.
Besides that, imx7ulp lpuart has a minor different register layout
from ls1021a that it has four extra registers (verid, param, global,
pincfg) located at the beginning o

On new LPUART versions, the oversampling ratio for the receiver can be
changed from 4x (00011) to 32x (1) which could help us get a more
accurate baud rate divider.
The idea is to use the best OSR (over-sampling rate) possible.
Note, OSR is typically hard-set to 16 in other LPUART instantiatio

Do not keep `printk_pending' in per-CPU area. We set the following bits
of printk_pending:
a) PRINTK_PENDING_WAKEUP

to call console_unlock().

Implement PWM dead-times for atmel PWM controllers.
Since this driver is used by PWM controllers which
supports dead-times and PWM controllers which doesn't,
add specific input for dead-time register in atmel
register private data structure.

possible. By default `atomic_print_limit' is set to 0, so no
offloading will take place, unless requested by user.

It's not always possible/safe to wake_up() printk kernel
thread. For example, late suspend/early resume may printk()
while timekeeping is not initialized yet, so calling into the
scheduler may result in recursive warnings.
Another thing to notice is the fact PM at some point

The notions introduced are rising edge dead-time

printk() is quite complex internally and, basically, it does two
slightly independent things:
a) adds a new message to a kernel log buffer (log_store())
b) prints kernel log messages to serial consoles (console_unlock())
while (a) is guaranteed to be executed by printk(), (b) is not, for a

On some Layerscape boards like LS2085ARDB/LS2080ARDB,
input pull-up resistors on PCA954x Mux device are
missing on board. So, if mux are disabled after powered-on,
input lines will float leading to incorrect functionality.
Hence, PCA954x Mux device should never be turned-off

I dare to point change possibilities out which correspond to a special error

When using trace_dump_stack() you currently just get a list of function
names.
It can be very useful to know exactly where a call came from, especially
if there are multiple calls from one function to another.
By switching trace_dump_stack() to use %pF we get the function name and
the offset, whi

In order to reduce power consumption and bus traffic, it is sensible
for secondary cores to enter a low-power idle state when waiting to
