Merge tag 'nios2-v3.19-rc1' of git://git.rocketboards.org/linux-socfpga-next
Pull Altera Nios II processor support from Ley Foon Tan:
"Here is the Linux port for Nios II processor (from Altera) arch/nios2/
tree for v3.19.
The patchset has been discussed on the kernel mailing lists since
April and has gone through 6 revisions of review. The additional
changes since then have been mostly further cleanups and fixes when
merged with other trees.
The arch code is in arch/nios2 and one asm-generic change (acked by
Arnd)"
Arnd Bergmann says:
"I've reviewed the architecture port in the past and it looks good in
its latest version"

This patch is the usual mix of driver updates (srp, ipr, scsi_debug, NCR5380,
fnic, 53c974, ses, wd719x, hpsa, megaraid_sas). Of those, wd7a9x is new and
53c974 is a rewrite of the old tmscsim driver and the extensive work by Finn
Thain rewrites all the NCR5380 based drivers. There's also extensive

performance requirements that were requested by the Gluster

aggregate IO that will be issued to the same thinp block before
issuing IO to the underlying devices. This really helps improve
performance on HW RAID6 devices that have a writeback cache because it
avoids RMW in the HW RAID controller.
- Some stable fixes: fix leak in DM bufio if integrity profiles were
enabled, use memzero_explicit in DM crypt to avoid any potential for
information leak, and a DM cache fix to properly mark a cache block
dirty if it was promoted to the cache via the overwrite optimization.
- A few simple DM persistent data library fixes
- DM cache multiqueue policy block promotion improvements.
- DM cache discard improvements that take advantage of range
(multiblock) discard support in the DM bio-prison. This allows for
much more efficient bulk discard processing (e.g. when mkfs.xfs
discards the entire device).
- Some small optimizations in DM core and RCU deference cleanups
- DM core changes to suspend/resume code to introduce the new internal
suspend/resume interface that the DM thin-pool target now uses to
suspend/resume active thin devices when the thin-pool must
suspend/resume. This avoids forcing userspace to track all active
thin volumes in a thin-pool when the thin-pool is suspended for the
purposes of metadata or data space resize.

Allow reading of timestamps and cmsg at the same time on all relevant
socket families. One use is to correlate timestamps with egress
device, by asking for cmsg IP_PKTINFO.
on AF_INET sockets, call the relevant function (ip_cmsg_recv). To
avoid changing legacy expectations, only do so if the caller sets a
new timestamping flag SOF_TIMESTAMPING_OPT_CMSG.
on AF_INET6 sockets, IPV6_PKTINFO and all other recv cmsg are already
returned for all origins. only change is to set ifindex, which is
not initialized for all error origins.
In both cases, only generate the pktinfo message if an ifindex is
known. This is not the case for ACK timestamps.
The difference between the protocol families is probably a historical
accident as a result of the different conditions for generating cmsg
in the relevant ip(v6)_recv_error function:
ipv4: if (serr->ee.ee_origin == SO_EE_ORIGIN_ICMP) {
ipv6: if (serr->ee.ee_origin != SO_EE_ORIGIN_LOCAL) {
At one time, this was the same test bar for the ICMP/ICMP6
distinction. This is no longer true.

Changes
v1 -> v2
large rewrite
- integrate with existing pktinfo cmsg generation code
- on ipv4: only send with new flag, to maintain legacy behavior
- on ipv6: send at most a single pktinfo cmsg
- on ipv6: initialize fields if not yet initialized
The recv cmsg interfaces are also relevant to the discussion of
whether looping packet headers is problematic. For v6, cmsgs that
identify many headers are already returned. This patch expands

Lots and lots of changes this time around, the usual set of driver
updates and a huge bulk of cleanups from Lars-Peter. Probably the most
interesting thing for most users is the Intel driver updates which will
(with some more machine integration work) enable support for newer x86
laptops.
- Conversion of AC'97 drivers to use regmap, bringing us closer to the
removal of the ASoC level I/O code.
- Clean up a lot of old drivers that were open coding things that have
subsequently been implemented in the core.
- Some DAPM performance improvements.
- Removal of the now seldom used CODEC mutex.
- Lots of updates for the newer Intel SoC support, including support
for the DSP and some Cherrytrail and Braswell machine drivers.
- Support for Samsung boards using rt5631 as the CODEC.
- Removal of the obsolete AFEB9260 machine driver.
- Driver support for the TI TS3A227E headset driver used in some

The last time this documentation was accurate was
just over 8 years ago. In this time we've added
support for two new generations of Xbox console
controllers and dozens of third-party controllers.
This patch unifies terminology and makes it explicit
which model of controller a sentence refers to.
It also expands certain sections to address the latest
versions of Xbox controllers.
Thus this documentation should now be useful to
end users and not contain out-right untruths.
This is the patch's second revision. Prior versions
of this patch altered the driver's TODO list. That
change has been pulled out of this documentation

These are a pre-req to get rk3288 SMP to work with some firmwares, so merge

* clocksource/physical-timers:

clocksource: arch_timer: Fix code to use physical timers when requested
* clocksource/physical-timers:
clocksource: arch_timer: Allow the device tree to specify uninitialized timer registers
clocksource: arch_timer: Fix code to use physical timers when requested
Some 32-bit (ARMv7) systems are architected like this:
* The firmware doesn't know and doesn't care about hypervisor mode and
we don't want to add the complexity of hypervisor there.
* The firmware isn't involved in SMP bringup or resume.
* The ARCH timer come up with an uninitialized offset (CNTVOFF)
between the virtual and physical counters. Each core gets a
different random offset.
* The device boots in "Secure SVC" mode.
* Nothing has touched the reset value of CNTHCTL.PL1PCEN or
CNTHCTL.PL1PCTEN (both default to 1 at reset)
On systems like the above, it doesn't make sense to use the virtual
counter. There's nobody managing the offset and each time a core goes
down and comes back up it will get reinitialized to some other random
value.
This adds an optional property which can inform the kernel of this
situation, and firmware is free to remove the property if it is going
to initialize the CNTVOFF registers when each CPU comes out of reset.
Currently, the best course of action in this case is to use the
physical timer, which is why it is important that CNTHCTL hasn't been
changed from its reset value and it's a reasonable assumption given
that the firmware has never entered HYP mode.
Note that it's been said that on ARMv8 systems the firmware and
kernel really can't be architected as described above. That means
using the physical timer like this really only makes sense for ARMv7
systems.

Currently, function graph tracer prints "!" or "+" just before
function execution time to signal a function overhead, depending
on the time. And some tracers tracing latency also print "!" or
"+" just after time to signal overhead, depending on the interval
between events. Even it is usually enough to do that, we sometimes
need to signal for bigger execution time than 100 micro seconds.
For example, I used function graph tracer to detect if there is
any case that exit_mm() takes too much time. I did following steps
in /sys/kernel/debug/tracing. It was easier to detect very large
excution time with patched kernel than with original kernel.
$ echo exit_mm > set_graph_function
$ echo function_graph > current_tracer
$ echo > trace
$ cat trace_pipe > $LOGFILE
... (do something and terminate logging)
$ grep "\\$" $LOGFILE

3) $ 22206949 us | } /* exit_mmap */
3) $ 22207659 us | } /* mmput */
3) $ 22207793 us | } /* exit_mm */
And then, it was easy to find out that a schedule-out occured by
sub_preempt_count() within kernel_map_pages().
To detect very large function exection time caused by either problematic
function implementation or scheduling issues, this patch can be useful.

I added a paragraph on choosing label names, and updated the example
code to use a better label name. I also cleaned up the example code to
more modern style by moving the allocation out of the initializer and
changing the NULL check.
Perhaps the most common type of error handling bug in the kernel is "one
err bugs". CodingStyle already says that we should "avoid nesting" by
using error labels and one err style error handling tends to have
multiple indent levels, so this was already bad style. But I've added a
new paragraph explaining how to avoid one err bugs by using multiple
error labels which is, hopefully, more clear.

It reverts commit a4b4e0461e ("of: Add standard property for poweroff capability").
As discussed on the mailing list, it makes more sense to rename back to the
old established property name, without the vendor prefix. Problem being that
the word "source" usually tends to be used for inputs and that is out of control
of the OS. The poweroff capability is an output which simply turns the
system-power off. Also, this property might be used by drivers which power-off
the system and power back on subsequent RTC alarms. This seems to suggest to
remove "poweroff" from the property name and to choose "system-power-controller"
as the more generic name. This patchs adds the required renaming changes and
defines an helper function which checks if this property is set.

This commit extends the mvebu-mbus driver to provide suspend/resume
support. Since mvebu-mbus is not a platform_driver, the syscore_ops
mechanism is used to get ->suspend() and ->resume() hooks called into
the driver.
In those hooks, we save and restore the MBus windows state, to make
sure after resume all Mbus windows are properly restored. Note that
while the state of some windows could be gathered by looking again at
the Device Tree (for statically described windows), it is not the case
of dynamically described windows such as the PCIe memory and I/O
windows. Therefore, we take the simple approach of saving and
restoring the registers for all MBus windows.
In addition, the commit extends the Device Tree binding of the MBus
controller, to control the MBus bridge registers (which define which
parts of the physical address space is routed to MBus windows
vs. normal RAM memory). Those registers must be saved and restored
during suspend/resume. The Device Tree binding extension is made is a
backward compatible fashion, but of course, suspend/resume will not
work without the Device Tree update.

Make the map match the reality, the current binding text is
nonsense:
- The clock required for the clocking of the serial port
must come first and is not optional (as the driver will
otherwise proceed to grab and use the apb_pclk as uartclk),
and the apb_pclk that clocks the logic must come second
as the code will retrieve the first clock by index,
whereas the PrimeCell but will explicitly look for
"apb_pclk" so this can be specified later, as it is
looked up by name.
- The pin control state "default" is the only mandated
state, the sleep state is entirely optional.
We also add an example to avoid further confusion.

The task_collector mode (or "latency_injector", (C) Dan Willians) is an
optional I/O path in libsas that queues up scsi commands instead of
directly sending it to the hardware. It generall increases latencies
to in the optiomal case slightly reduce mmio traffic to the hardware.
Only the obsolete aic94xx driver and the mvsas driver allowed to use
it without recompiling the kernel, and most drivers didn't support it
at all.

* SIRF timer updates from Yanchang Li
- Make clock rate configurable
The OMAP mailbox driver and its existing clients (remoteproc
for OMAP4+) are adapted to use the generic mailbox framework.
The main changes for the adaptation are:
- The tasklet used for Tx is replaced with the state machine from
the generic mailbox framework. The workqueue used for processing
the received messages stays intact for minimizing the effects on
the OMAP mailbox clients.
- The existing exported client API, omap_mbox_get, omap_mbox_put and
omap_mbox_send_msg are deleted, as the framework provides equivalent
functionality. A OMAP-specific omap_mbox_request_channel is added
though to support non-DT way of requesting mailboxes.
- The OMAP mailbox driver is integrated with the mailbox framework
through the proper implementations of mbox_chan_ops, except for
.last_tx_done and .peek_data. The OMAP mailbox driver does not need
these ops, as it is completely interrupt driven.
- The OMAP mailbox driver uses a custom of_xlate controller ops that
allows phandles for the pargs specifier instead of indexing to avoid
any channel registration order dependencies.
- The new framework does not support multiple clients operating on a
single channel, so the reference counting logic is simplified.
- The remoteproc driver (current client) is adapted to use the new API.
The notifier callbacks used within this client is replaced with the
regular callbacks from the newer framework.
- The exported OMAP mailbox API are limited to omap_mbox_save_ctx,
omap_mbox_restore_ctx, omap_mbox_enable_irq & omap_mbox_disable_irq,
with the signature modified to take in the new mbox_chan handle instead
of the OMAP specific omap_mbox handle. The first 2 will be removed when
the OMAP mailbox driver is adapted to runtime_pm. The other exported
API omap_mbox_request_channel will be removed once existing legacy
users are converted to DT.

Some regulators can run on different operating modes (opmodes). This
allows systems to choose the most efficient opmode for each regulator.
This patch builds on top of (291d761 regulator: Document binding for
regulator suspend state for PM state) adding a regulator-initial-mode
DT property to configure at startup the operating mode for regulators
that support changing its mode during normal operation and a property
regulator-mode to be used in the regulator-state-[mem/disk] nodes for
regulators that supports changing its operating mode when the system
enters in a suspend state.
The set of possible modes that a regulator can operate depends on the
hardware capabilities so a list of generic operating modes can't be
provided. Instead, each hardware binding should define the list of
valid operating modes for the regulators found on that device.
