Pull printk updates from Petr Mladek:
- Help userspace log daemons to catch up with a flood of messages. They
will get woken after each message even if the console is far behind
and handled by another process.
- Flush printk safe buffers safely even when panic() happens in the
normal context.
- Fix possible va_list reuse when race happened in printk_safe().
- Remove %pCr printf format to prevent sleeping in the atomic context.
- Misc vsprintf code cleanup.

Printk format "%pCr" will be removed soon, as clk_get_rate() must not be
called in atomic context.
Replace it by open-coding the operation. This is safe here, as the code
runs in task context.

Printk format "%pCr" will be removed soon, as clk_get_rate() must not be
called in atomic context.
Replace it by printing the variable that already holds the clock rate.
Note that calling clk_get_rate() is safe here, as the code runs in task
context.

Pull IPMI updates from Corey Minyard:
"It's been a busy release for the IPMI driver. Some notable changes:
- A user was running into timeout issues doing maintenance commands
over the IPMB network behind an IPMI controller.
Extend the maintenance mode concept to messages over IPMB and allow
the timeouts to be tuned.
- Lots of cleanup, style fixing, some bugfixes, and such.
- At least one user was having trouble with the way the IPMI driver
would lock the i2c driver module it used.
The IPMI driver was not designed for hotplug. However, hotplug is a
reality now, so the IPMI driver was modified to support hotplug.
- The proc interface code is now completely removed. Long live sysfs!"

Original kcs_bmc_npcm7xx.c was missing enabling to send interrupt to the
host on writes to output buffer.
This patch fixes it by setting the bits that enables the generation of
IRQn events by hardware control based on the status of the OBF flag.

There was one place where the timeout value for an operation was
not being set, if a capabilities request was done from idle. Move
the timeout value setting to before where that change might be
requested.
IMHO the cause here is the invisible returns in the macros. Maybe
that's a job for later, though.

This driver exposes the Keyboard Controller Style (KCS) interface on
Novoton NPCM7xx SoCs as a character device. Such SOCs are commonly used
as a BaseBoard Management Controller (BMC) on a server board, and KCS
interface is commonly used to perform the in-band IPMI communication
between the server and its BMC.

The mutex didn't really serve any useful purpose, from what I can
tell, and it would just get in the way. So remove it.
Removing that required a mutex around the default value setting and
getting, so just use the receive mutex for that.
Also pull the fasync stuff outside of the lock for adding the data
to the queue, since it didn't need to be there.

Users of the IPMI code had their own panic handlers, but the
order was not necessarily right, the base IPMI code would
need to handle the panic first, and the user had no way to
know if the IPMI interface could run at panic time.
Add a panic handler to the user interface, it is called if
non-NULL and the interface the user is on is capable of panic
handling. It also cleans up the panic log handling a bit to
reuse the existing interface loop in the main panic handler.

Simplify things by creating one set of message handling data for
setting the watchdog and doing a heartbeat. Rework the locking
to avoid some (probably not very important) races and to avoid
a fairly unlikely infinite recursion.
Get rid of ipmi_ignore_heartbeat, it wasn't used, and use
watchdog_user to tell if we have a working IPMI device below
us.

By default the retry timeout is 1 second. Allow that to be modified,
primarily for slow operations, like firmware writes.
Also, the timeout was driven by a 1 second timer, so 1 second really
meant between 0 and 1 second. Set the default to 2 seconds so it
means between 1 and 2 seconds.
Also allow the time the interface automatically stays in mainenance
mode to be modified from it's default 30 seconds.
Also consolidate some of the timeout and retry setup.

Prevent build error when CONFIG_ACPI_NFIT=m and CONFIG_EDAC_SKX=y by
limiting EDAC_SKX based on how ACPI_NFIT is set.
Fixes this build error:
drivers/edac/skx_edac.o: In function `get_nvdimm_info':

The ghes_edac driver obtains memory type from SMBIOS type 17, but it
does not recognize DDR4 and NVDIMM types.
Add support of DDR4 and NVDIMM types. NVDIMM type is denoted by memory
type DDR3/4 and non-volatile.

On Stratix10, uncorrectable errors are routed to the SError exception
instead of the IRQ exceptions. In Stratix10, uncorrectable SErrors
must be treated as fatal and will cause a panic. Older Altera/Intel
parts printed out a message for UE so do that here using the notifier
framework.
Record the UE in sticky registers that retain the state through a reset.
Check these registers on probe and printout the error on startup.

Add a null check for ghes_pvt, before dereferencing it. The pointer
could still be null in case the return path is taken before initialising
ghes_pvt in the registration function.

Tony reported seeing
"Internal error: Can't find EDAC structure"
when injecting correctable errors due to the fact that ghes_edac would
still load even if the whitelist won't hit. Drop the pr_err() in
ghes_edac_report_mem_error() for now due to the hacky way how ghes_edac
depends on ghes.c.
While at it, make ghes_edac_register() return an error if it doesn't hit
in the whitelist as it is the only sensible thing to do in that
situation.
Furthermore, move the call to it to happen last in ghes_probe() so that
GHES initializing properly does not depend on ghes_edac init at all
as latter is only reporting errors and not required for GHES's proper
functioning.

This patch is provided in the context of allowing the Coresight driver
subsystem to be loaded as modules. Coresight uses amba_bus in its call
to bus_find_device() in of_coresight_get_endpoint_device() when
searching for a configurable endpoint device. This patch allows
Coresight to reference amba_bustype when built as a module.
