If the hardware watchdog in the clock chip simply pulls the reset line

Hi all,
Today's linux-next merge of the vhost tree got a conflict in:
drivers/scsi/virtio_scsi.c
between commit:
92e8d0323a51 ("scsi: virtio_scsi: Remove unnecessary condition check")
from the scsi tree and commit:
3dfd411ea7ec ("scsi: virtio_scsi: remove unnecessary condition check")
The crash_exclude_mem_range() can only handle one memory region one time.
It will fail the case in which the passed in area covers several memory
regions. In the case, it will only exclude the first region, then return,
but leave the later regions unsolved.
E.g in a NEC system with two usable RAM
Currently, when we enable the debugging switch to debug kexec_file,

kexec_file: Crash PT_LOAD elf header. phdr=3cca69a0 vaddr=0x0,
This series includes the following patches, it fixes some corners bugs
and improves the crash_exclude_mem_range().

parameters
[2] [PATCH 2/3] kexec: Improve the crash_exclude_mem_range() to handle

Let's carefully handle the boundary of the function parameter to make

The OpenRISC user access functions put_user(), get_user() and
clear_user() were missing proper sparse annotations. This generated
warnings like the below.
This patch adds the annotations to fix the warnings.
Example warnings:
net/ipv4/ip_sockglue.c:759:29: warning: incorrect type in argument 1
Hello,
This a series of fixes for OpenRISC sparse warnings. The kbuild robots report
many issues related to issues with OpenRISC headers having missing or incorrect
sparse annotations.
Example kdbuild-all report:
net/ipv4/ip_sockglue.c:1489:13: sparse: sparse: incorrect type in initializer
The __user annotations in signal.c were mostly missing. The missing
annotations caused the warnings listed below. This patch fixes them up
by adding the __user annotations.
arch/openrisc/kernel/signal.c:71:38: warning: incorrect type in initializer
(different address spaces)
Now that __user annotations are fixed for openrisc uaccess api's we can
add checking to the access_ok macro. This patch adds the __chk_user_ptr
check, on normal builds the added check is a nop.

As suggested by Linus when reviewing commit 9cb2feb4d21d
("arch/openrisc: Fix issues with access_ok()") last year; making
__range_ok an inline function also fixes the used twice issue that the
commit was fixing. I agree it's a good cleanup. This patch addresses
that as I am currently working on
This didn't seem to cause any issues, but while working on fixing up
sparse annotations for OpenRISC I noticed this. This patch moves the
include of asm-generic/io.h to the end of the file. Also, we add
defines of ioremap and iounmap, that way we don't get duplicate
definitions from
Since commit b48b2c3e5043 ("openrisc: use generic strnlen_user()
function") the macro __addr_ok is no longer used. It is safe to remove
so this patch removes it.

On big-endian architectures like OpenRISC, sparse outputs below warnings on
asm-generic/io.h. This is due to io statements like:
__raw_writel(cpu_to_le32(value), PCI_IOBASE + addr);
The __raw_writel() function expects native endianness, however

The function of mtk_jpeg_adjust_fmt_mplane() equals
mtk_jpeg_g_fmt_vid_mplane(), so use mtk_jpeg_g_fmt_vid_mplane() to
replace it .
Delete the unused ctx parameter.
Using fourcc to distinguish between different formats is more generic,
because that jpeg enc will also use it.

There is a delayed work scheduled before starting the hardware and
canceled in the interrupt handler. If the delayed work is executed, it
resets the hardware and reports the failure to V4L2, so that the
execution can continue from next frames.

The driver can be instantiated multiple times, e.g. for a decoder and
an encoder. Moreover, other drivers could coexist on the same system.
This makes the static video node number assignment pointless, so switch
to automatic assignment instead.

On Power9 a pair of cores can be presented by the firmware as a big-core
for backward compatibility reasons, with 4 threads per (small) core and 8
threads per big-core. cpu_smt_mask() should generally point to the cpu mask
of the (small)core.

cpu_smt_mask tracks topology_sibling_cpumask. This would be good for
most architectures. One of the users of cpu_smt_mask(), would be to
identify idle-cores. On Power9, a pair of cores can be presented by the
firmware as a big-core for backward compatibility reasons.
