When excuting a command like:
modprobe ipmi_si ports=0xffc0e3 type=bt
The system would get an oops.
The trouble here is that ipmi_si_hardcode_find_bmc() is called before
ipmi_si_platform_init(), but initialization of the hard-coded device
creates an IPMI platform device, which won't be initialized yet.
The real trouble is that hard-coded devices aren't created with
any device, and the fixup is done later. So do it right, create the
hard-coded devices as normal platform devices.
This required adding some new resource types to the IPMI platform
code for passing information required by the hard-coded device
and adding some code to remove the hard-coded platform devices
on module removal.
To enforce the "hard-coded devices passed by the user take priority
over firmware devices" rule, some special code was added to check
and see if a hard-coded device already exists.

The user can ask the message to be returned even if it didn't supply
enough memory for the data, and it will return an error but still
fills in as much data as possible. However, the return value
wasn't being set to an error, it was being overwritten. Create a

The code to tell the lower layer to enable or disable watching for
certain things was lazy in disabling, it waited until a timer tick
to see if a disable was necessary. Not a really big deal, but it
could be improved.
Modify the code to enable and disable watching immediately and don't
do it from the background timer any more.

The IPMI driver has a mechanism to tell the lower layers it needs
to watch for messages, commands, and watchdogs (so it doesn't
needlessly poll). However, it needed some extensions, it needed
a way to tell what is being waited for so it could set the timeout
appropriately.
The update to the lower layer was also being done once a second
at best because it was done in the main timeout handler. However,
if a command is sent and a response message is coming back,
it needed to be started immediately. So modify the code to
update immediately if it needs to be enabled. Disable is still
lazy.

Commit 89986496de ("ipmi: Turn off all activity on an idle ipmi
interface") modified the IPMI code to only request events when the
driver had somethine waiting for events. The SSIF code, however,
was using the event fetch request to also fetch the flags.
Add a timer and the proper handling for the upper layer telling
whether flags fetches are required.

- A workaround for a Loongson 3 CPU bug is the biggest change, but
still fairly straightforward. It adds extra memory barriers (sync
instructions) around atomics to avoid a CPU bug that can break
atomicity.
- Loongson64 also sees a fix for powering off some systems which would
incorrectly reboot rather than waiting for the power down sequence to
complete.
- We have DT fixes for the Ingenic JZ4740 SoC & the JZ4780-based Ci20
board, and a DT warning fix for the Nexsys4/MIPSfpga board.
- The Cavium Octeon platform sees a further fix to the behaviour of the
pcie_disable command line argument that was introduced in v3.3.
- The VDSO, introduced in v4.4, sees build fixes for configurations of
GCC that were built using the --with-fp-32= flag to specify a default
32-bit floating point ABI.
- get_frame_info() sees a fix for configurations with
CONFIG_KALLSYMS=n, for which it previously always returned an error.
- If the MIPS Coherence Manager (CM) reports an error then we'll now

The ->inflight counter may be negative (-1) if
1) blk-iolatency was disabled when the IO was issued,
2) blk-iolatency was enabled before this IO reached its endio,
3) the ->inflight counter is decreased from 0 to -1 in endio()
In fact the hang can be easily reproduced by the below script,
H=/sys/fs/cgroup/unified/
P=/sys/fs/cgroup/unified/test
echo "+io" > $H/cgroup.subtree_control
mkdir -p $P
echo $$ > $P/cgroup.procs
xfs_io -f -d -c "pwrite 0 4k" /dev/sdg
echo "`cat /sys/block/sdg/dev` target=1000000" > $P/io.latency
xfs_io -f -d -c "pwrite 0 4k" /dev/sdg
This fixes the problem by freezing the queue so that while
enabling/disabling iolatency, there is no inflight rq running.
Note that quiesce_queue is not needed as this only updating iolatency
configuration about which dispatching request_queue doesn't care.

Here are some driver core fixes for 5.0-rc6.
Well, not so much "driver core" as "debugfs". There's a lot of
outstanding debugfs cleanup patches coming in through different
subsystem trees, and in that process the debugfs core was found that it
really should return errors when something bad happens, to prevent
random files from showing up in the root of debugfs afterward. So
debugfs was fixed up to handle this properly, and then two fixes for
the relay and blk-mq code was needed as it was making invalid
assumptions about debugfs return values.
There's also a cacheinfo fix in here that resolves a tiny issue.

Fixes the issues with non BCM58XX chips in the b53 driver
failing, when the irq is not specified in the device tree.
Removed the check for BCM58XX in b53_srab_prepare_irq(),
so the 'port->irq' will be set to '-EXIO' if the irq is not
specified in the device tree.
Fixes: 16994374a6 ("net: dsa: b53: Make SRAB driver manage port interrupts")
Fixes: b2ddc48a81 ("net: dsa: b53: Do not fail when IRQ are not initialized")

Currently, blktrace will not show requests that don't have any data as
rq->__sector is initialized to -1 which is out of device range and thus
discarded by act_log_check(). This is most notably the case for cache
flush requests sent to the device. Fix the problem by making
blk_rq_trace_sector() return 0 for requests without initialized sector.

The GCR_ERROR_CAUSE.ERR_TYPE field and the GCR_ERROR_MULT.ERR_TYPE
fields can be cleared by either a reset or by writing the current
value of GCR_ERROR_CAUSE.ERR_TYPE to the
GCR_ERROR_CAUSE.ERR_TYPE register.

Do exactly this. Original value of cm_error may be safely written back;
it clears error cause and keeps other bits untouched.

On my Yeeloong 8089, I noticed the machine fails to shutdown
properly, and often, the function mach_prepare_reboot() is
unexpectedly executed, thus the machine reboots instead. A
wait loop is needed to ensure the system is in a well-defined
state before going down.
In commit 997e93d4df ("MIPS: Hang more efficiently on
halt/powerdown/restart"), a general superset of the wait loop for all
platforms is already provided, so we don't need to implement our own.
This commit simply removes the unreachable() compiler marco after
mach_prepare_reboot(), thus allowing the execution of machine_hang().
My test shows that the machine is now able to shutdown successfully.
Please note that there are two different bugs preventing the machine
from shutting down, another work-in-progress commit is needed to
fix a lockup in cpufreq / i8259 driver, please read Reference, this
commit does not fix that bug.

====================
fix two kernel panics when disabled IPv6 on boot up
When disabled IPv6 on boot up, since there is no ipv6 route tables, we should
not call rt6_lookup. Fix them by checking if we have inet6_dev pointer on
netdevice.
v2: Fix idev reference leak, declarations and code mixing as Stefano,
Eric pointed. Since we only want to check if idev exists and not
reference it, use __in6_dev_get() insteand of in6_dev_get().
====================

If we disabled IPv6 from the kernel command line (ipv6.disable=1), we should
not call ip6_err_gen_icmpv6_unreach(). This:
ip link add sit1 type sit local 192.0.2.1 remote 192.0.2.2 ttl 1
ip link set sit1 up
ip addr add 198.51.100.1/24 dev sit1
ping 198.51.100.2
if IPv6 is disabled at boot time, will crash the kernel.
v2: there's no need to use in6_dev_get(), use __in6_dev_get() instead,
as we only need to check that idev exists and we are under
rcu_read_lock() (from netif_receive_skb_internal()).

When we add a new GENEVE device with IPv6 remote, checking only for
IS_ENABLED(CONFIG_IPV6) is not enough as we may disable IPv6 in the
kernel command line (ipv6.disable=1), and calling rt6_lookup() would
cause a NULL pointer dereference.
v2:
- don't mix declarations and code (reported by Stefano Brivio, Eric Dumazet)
- there's no need to use in6_dev_get() as we only need to check that
idev exists (reported by David Ahern). This is under RTNL, so we can
simply use __in6_dev_get() instead (Stefano, Eric).
