Hi Timur,
Sorry, how do you trigger a panic if WS1 ties to reset ?? don't know
what is your question
could you make it simple:
1) calling panic() on pre-timeout (WS0)
2) calling panic() on timeout (WS1)
in first version , I just print the timeleft for WS1 or panic when
WS0 occurs.

Hi all,
I noticed a regression on my arm64 APM X-Gene system a couple
of weeks back. I would occassionally see the system lock up and see RCU
stalls during the caching phase of kernbench. I then wrote a small
script that does nothing but cache the files
(http://paste.ubuntu.com/11324767/) and
Use the generic irqchip_init function to probe irqchip drivers using DT,
and add the appropriate node to the JZ4740 devicetree in place of the
call to mips_cpu_irq_init.

Make use of the generic plat_irq_dispatch function introduced by commit

Rather than hardcoding the IRQ number used to cascade interrupts from
the SoC interrupt controller to the CPU interrupt controller, read that
IRQ number from the DT describing the system.

Require a DT for JZ4740 based systems, and add a stub one for the
qi_lb60 (Ben NanoNote) board. Devices will be migrated to being probed
via this DT over time.

Allow the MIPS CPU interrupt controller to be probed from DT using the
generic __irqchip_of_table for platforms which use irqchip_init. This
will avoid such platforms needing to duplicate the compatible string

Introduce a driver suitable for use with the UARTs present in
Ingenic SoCs such as the JZ4740 JZ4780. These are described as being
ns16550 compatible but aren't quite - they require the setting of an
extra bit in the FCR register to enable the UART module. The serial_out
implementation is the
The jz4740-cgu driver already has access to the CGU, so it makes sense
to move the few remaining accesses to the CGU from arch/mips/jz4740
there too. Move the jz4740_clock_{suspend,resume} functions there for
such consistency. The arch/mips/jz4740/clock.c file now contains nothing
more of use so
Fork-routine sometimes fails to get a physically contiguous region for
thread_info on 4KB page system although free memory is enough. That is,
a physically contiguous region, which is currently 16KB, is not available
since system memory is fragmented.
This patch tries to solve the problem as
A current implementation assumes thread_info address is always correctly
calculated via virt_to_page. It restricts a different approach, such as
thread_info allocation from vmalloc space.
This patch, thus, introduces an independent function to calculate page
address from thread_info one.

The current watchdog API suggests that the pretimeout allows Linux

means to make this happen.
Now that I think about it, that does make sense.

So this fix is wrong.
But you know, even if it was correct... IMO, the fixes like this can
only make sense as a while at it part of the meaningful change.

For interrupts numbered after those of the interrupt controller, define
their numbers based upon the number of interrupts provided by the SoC
interrupt controller. This is in preparation for supporting newer
Ingenic SoCs which provide more interrupts.
