* 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:

unsigned numbers in the ring-buffer code.
https://bugzilla.kernel.org/show_bug.cgi?id=118001
At first I did not think this was too much of an issue, because the
overflow would be caught later when either too much data was allocated
or it would trigger RB_WARN_ON() which shuts down the ring buffer.
But looking closer into it, I found that the right settings could bypass
the checks and crash the kernel. Luckily, this is only accessible
by root.
The first fix is to convert all the variables into long, such that
we don't get into issues between 32 bit variables being assigned 64 bit
ones. This fixes the RB_WARN_ON() triggering.
The next fix is to get rid of a duplicate DIV_ROUND_UP() that when called
twice with the right value, can cause a kernel crash.
The first DIV_ROUND_UP() is to normalize the input and it is checked
against the minimum allowable value. But then DIV_ROUND_UP() is called
again, which can overflow due to the (a + b - 1)/b, logic. The first
called upped the value, the second can overflow (with the +b part).
The second call to DIV_ROUND_UP() came in via a second change a while ago
and the code is cleaned up to remove it.

ring-buffer: Prevent overflow of size in ring_buffer_resize()

We saw the following extra refcount release on veth device:
kernel: [7957821.463992] unregister_netdevice: waiting for mesos50284 to become free. Usage count = -1
Since we heavily use mirred action to redirect packets to veth, I think
this is caused by the following race condition:
CPU0:
tcf_mirred_release(): (in RCU callback)
struct net_device *dev = rcu_dereference_protected(m->tcfm_dev, 1);
CPU1:
mirred_device_event():
spin_lock_bh(&mirred_list_lock);
list_for_each_entry(m, &mirred_list, tcfm_list) {
if (rcu_access_pointer(m->tcfm_dev) == dev) {
dev_put(dev);
/* Note : no rcu grace period necessary, as
* net_device are already rcu protected.
*/
RCU_INIT_POINTER(m->tcfm_dev, NULL);
}
}
spin_unlock_bh(&mirred_list_lock);
CPU0:
tcf_mirred_release():
spin_lock_bh(&mirred_list_lock);
list_del(&m->tcfm_list);
spin_unlock_bh(&mirred_list_lock);
if (dev) // <======== Stil refers to the old m->tcfm_dev
dev_put(dev); // <======== dev_put() is called on it again
The action init code path is good because it is impossible to modify
an action that is being removed.
So, fix this by moving everything under the spinlock.

configure the device/firmware with the dcbx results. Management Firmware
is responsible for communicating the DCBX and driving the negotiation,

configuring the results in hw/fw. This patch also adds the dcbx support for

When reopening the network device on ra7795/salvator-x, e.g. after a
DHCP timeout:
IP-Config: Reopening network devices...
genirq: Flags mismatch irq 139. 00000000 (eth0:ch0:rx_be) vs. 00000000 (ravb e6800000.ethernet eth0: cannot request IRQ eth0:ch0:rx_be
IP-Config: Failed to open eth0
IP-Config: No network devices available
The "mismatch" is due to requesting an IRQ that is already in use,
while IRQF_PROBE_SHARED wasn't set.
However, the real cause is that ravb_close() doesn't release any of the
R-Car Gen3-specific secondary IRQs.
Add the missing free_irq() calls to fix this.

PIC32 clock driver is now implemented as platform driver instead of
as part of of_clk_init(). It meants all the clock modules are available
quite late in the boot sequence. So request for CPU clock by clk_get_sys()
and clk_get_rate() to find c0_timer rate fails.
To fix this use PIC32 specific early clock functions implemented for early
console support.

The VZ guest register & TLB access macros introduced in commit "MIPS:
Add guest CP0 accessors" use VZ ASE specific instructions that aren't
understood by versions of binutils prior to 2.24.
Add a check for whether the toolchain supports the -mvirt option,
similar to the MSA toolchain check, and implement the accessors using
.word if not.
Due to difficulty in converting compiler specified registers (e.g. "$3")
to usable numbers (e.g. "3") in inline asm, we need to copy to/from a
temporary register, namely the assembler temporary (at/$1), and specify
guest CP0 registers numerically in the gc0 macros.

Pull power management updates from Rafael Wysocki:
"The majority of changes go into the cpufreq subsystem this time.
To me, quite obviously, the biggest ticket item is the new "schedutil"
governor. Interestingly enough, it's the first new cpufreq governor
since the beginning of the git era (except for some out-of-the-tree
ones).
There are two main differences between it and the existing governors.
First, it uses the information provided by the scheduler directly for
making its decisions, so it doesn't have to track anything by itself.
Second, it can invoke drivers (supporting that feature) to adjust CPU
performance right away without having to spawn work items to be
executed in process context or similar. Currently, the acpi-cpufreq
driver is the only one supporting that mode of operation, but then it
is used on a large number of systems.
The "schedutil" governor as included here is very simple and mostly
regarded as a foundation for future work on the integration of the
scheduler with CPU power management (in fact, there is work in
progress on top of it already). Nevertheless it works and the
preliminary results obtained with it are encouraging.
There also is some consolidation of CPU frequency management for ARM
platforms that can add their machine IDs the the new stub dt-platdev
driver now and that will take care of creating the requisite platform
device for cpufreq-dt, so it is not necessary to do that in platform
code any more. Several ARM platforms are switched over to using this
generic mechanism.
In addition to that, the intel_pstate driver is now going to respect
CPU frequency limits set by the platform firmware (or a BMC) and
provided via the ACPI _PPC object.
The devfreq subsystem is getting a new "passive" governor for SoCs
subsystems that will depend on somebody else to manage their voltage
rails and its support for Samsung Exynos SoCs is consolidated.
The rest is support for new hardware (Intel Broxton support in
intel_idle for one example), bug fixes, optimizations and cleanups in
a number of places.
Specifics:
- New cpufreq "schedutil" governor (making decisions based on CPU
utilization information provided by the scheduler and capable of
switching CPU frequencies right away if the underlying driver
supports that) and support for fast frequency switching in the
acpi-cpufreq driver (Rafael Wysocki)

them to get rid of some platform-specific boilerplate code if they
are going to use the cpufreq-dt driver (Viresh Kumar, Finley Xiao,

A few core enhancements to deal with some of the slightly more
complicated edge cases that have started cropping up in systems, both
new ones and old ones that people started worrying about upstream, but
otherwise a quiet release for the regulator API:
- When applying constraints at system image if we have a voltage range
specified and the regulator is currently configured outside the
bounds of that range bring the regulator to the nearest end of the
range.
- When regulators are in non-regulating bypass modes make sure that we
always use the voltage from the parent regulator.
- Support for LP873x, PV88080, PM8894 and FAN53555 chips.

Pull LED updates from Jacek Anaszewski:
"In this merge cycle we had an interaction with MTD subsystem, that
included converting drivers/mtd/nand/nand_base.c to use newly
introduced MTD (NAND/NOR) LED trigger instead of implementing it on
its own.
Related MTD patches are intended to be merged through the LED tree,
before MTD tree is merged, since further MTD development is based on
those modifications.
Summary:
LEDs:
- Introduce a kernel panic LED trigger
- Introduce a MTD (NAND/NOR) trigger
- led-tca6507: silence an uninitialized variable warning
- ledtrig-ide-disk: Move ide_blink_delay to ledtrig_ide_activity()
- leds-ss4200: Add depend on x86 arch
- leds-ss4200: add DMI data for FSC SCALEO Home Server
- leds-triggers: Allow to switch the trigger to "panic" on a kernel panic
- devicetree: leds: Introduce "panic-indicator" optional property
- leds-gpio: Support the "panic-indicator" firmware property
MTD:
- Uninline mtd_write_oob and move it to mtdcore.c
- Remove the "nand-disk" LED trigger
- Hook I/O activity to the MTD LED trigger"

Unlike everywhere else in the IPMI specification, the I2C address
specified in the SPMI table is not shifted to the left one bit with
the LSB zero. Instead it is not shifted with the MSB zero.

Commit d61a3ead26 ("[PATCH] IPMI: reserve I/O ports separately")
changed the way I/O ports were reserved and includes this comment in
log:
Some BIOSes reserve disjoint I/O regions in their ACPI tables for the IPMI
controller. This causes problems when trying to register the entire I/O
region. Therefore we must register each I/O port separately.
There is a similar problem with memio regions on an arm64 platform
(AMD Seattle). Where I see:
ipmi message handler version 39.2
ipmi_si AMDI0300:00: probing via device tree
ipmi_si AMDI0300:00: ipmi_si: probing via ACPI
ipmi_si AMDI0300:00: [mem 0xe0010000] regsize 1 spacing 4 irq 23
ipmi_si: Adding ACPI-specified kcs state machine
IPMI System Interface driver.
ipmi_si: Trying ACPI-specified kcs state machine at mem \
address 0xe0010000, slave address 0x0, irq 23
ipmi_si: Could not set up I/O space
The problem is that the ACPI core registers disjoint regions for the
platform device:
e0010000-e0010000 : AMDI0300:00
e0010004-e0010004 : AMDI0300:00
and the ipmi_si driver tries to register one region e0010000-e0010004.
Based on a patch from Mark Salter <msalter@redhat.com>, who also wrote
all the above text.
