Pull irq fixes from Thomas Gleixner:
"Two small changes:
- a fix for a interrupt regression caused by the vector management
changes in 4.15 affecting museum pieces which rely on interrupt
probing for legacy (e.g. parallel port) devices.
One of the startup calls in the autoprobe code was not changed to
the new activate_and_startup() function resulting in a warning and
as a consequence failing to discover the device interrupt.
- a trivial update to the copyright/license header of the STM32 irq
chip driver"

Pull arm64 updates from Catalin Marinas:
"The main theme of this pull request is security covering variants 2
and 3 for arm64. I expect to send additional patches next week
covering an improved firmware interface (requires firmware changes)
for variant 2 and way for KPTI to be disabled on unaffected CPUs
(Cavium's ThunderX doesn't work properly with KPTI enabled because of
a hardware erratum).
Summary:
- Security mitigations:
- variant 2: invalidate the branch predictor with a call to
secure firmware
- variant 3: implement KPTI for arm64
- 52-bit physical address support for arm64 (ARMv8.2)
- arm64 support for RAS (firmware first only) and SDEI (software
delegated exception interface; allows firmware to inject a RAS
error into the OS)
- perf support for the ARM DynamIQ Shared Unit PMU
- CPUID and HWCAP bits updated for new floating point multiplication
instructions in ARMv8.4
- remove some virtual memory layout printks during boot
- fix initial page table creation to cope with larger than 32M kernel
images when 16K pages are enabled"

The ACPI specification says OS shouldn't attempt to use GICC configuration
parameters if the flag ACPI_MADT_ENABLED is cleared. The ARM64-SMP code
skips the disabled GICC entries but not causing any issue. However the
current GICv3 driver probe bails out causing kernel panic() instead of
skipping the disabled GICC interfaces. This issue happens on systems
where redistributor regions are not in the always-on power domain and
one of GICC interface marked with ACPI_MADT_ENABLED=0.
This patch does the two things to fix the panic.
- Don't return an error in gic_acpi_match_gicc() for disabled GICC entry.
- No need to keep GICR region information for disabled GICC entry.
Observed kernel crash on QDF2400 platform GICC entry is disabled.

The IRQ code already has support for lockdep class for the lock mutex
in an interrupt descriptor. Extend this to add a second class for the
request mutex in the descriptor. Not having a class is resulting in

Set I/O port resource structs to have IORESOURCE_IO in their type field.

Pull ARM SoC platform updates from Arnd Bergmann:
"Most of the commits are for defconfig changes, to enable newly added
drivers or features that people have started using. For the changed
lines lines, we have mostly cleanups, the affected platforms are OMAP,
Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions.
The largest single change is the introduction of the TI "sysc" bus
driver, with the intention of cleaning up more legacy code.
Two new SoC platforms get added this time:
- Allwinner R40 is a modernized version of the A20 chip, now with a
Quad-Core ARM Cortex-A7. According to the manufacturer, it is
intended for "Smart Hardware"
- Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family of
chips meant for managed gigabit ethernet switches, based around a
Cortex-A9 CPU.
Finally, we gain SMP support for two platforms: Renesas R-Car E2 and
Amlogic Meson8/8b, which were previously added but only supported
uniprocessor operation"

Pull irqchip updates for 4.15, take #4 from Marc Zyngier
- A core irq fix for legacy cases where the irq trigger is not reported
by firmware
- A couple of GICv3/4 fixes (Kconfig, of-node refcount, error handling)
- Trivial pr_err fixes
|

Pull irq core updates from Thomas Gleixner:
"A rather large update for the interrupt core code and the irq chip drivers:
- Add a new bitmap matrix allocator and supporting changes, which is
used to replace the x86 vector allocator which comes with separate
pull request. This allows to replace the convoluted nested loop
allocation function in x86 with a facility which supports the
recently added property of managed interrupts proper and allows to
switch to a best effort vector reservation scheme, which addresses
problems with vector exhaustion.
- A large update to the ARM GIC-V3-ITS driver adding support for
range selectors.
- New interrupt controllers:
- Meson and Meson8 GPIO
- BCM7271 L2
- Socionext EXIU
If you expected that this will stop at some point, I have to
disappoint you. There are new ones posted already. Sigh!
- STM32 interrupt controller support for new platforms.
- A pile of fixes, cleanups and updates to the MIPS GIC driver
- The usual small fixes, cleanups and updates all over the place.
Most visible one is to move the irq chip drivers Kconfig switches
into a separate Kconfig menu"

Pull OpenRISC updates from Stafford Horne:
"The OpenRISC work is a bit more interesting this time, adding SMP
support and a few general cleanups.
Small Things:
- Move OpenRISC docs into Documentation and clean them up
- Document previously undocumented devicetree bindings
- Update the or1ksim dts to use stdout-path
OpenRISC SMP support details:
- First the "use shadow registers" and "define CPU_BIG_ENDIAN as
true" get the architecture ready for SMP.
- The "add 1 and 2 byte cmpxchg support" and "use qspinlocks and
qrwlocks" add the SMP locking infrastructure as needed. Using the
qspinlocks and qrwlocks as suggested by Peter Z while reviewing the
original spinlocks implementation.
- The "support for ompic" adds a new irqchip device which is used for
IPI communication to support SMP.
- The "initial SMP support" adds smp.c and makes changes to all of
the necessary data-structures to be per-cpu.
The remaining patches are bug fixes and debug helpers which I wanted
to keep separate from the "initial SMP support" in order to allow them
to be reviewed on their own. This includes:
- add cacheflush support to fix icache aliasing
- fix initial preempt state for secondary cpu tasks
- sleep instead of spin on secondary wait
- support framepointers and STACKTRACE_SUPPORT
- enable LOCKDEP_SUPPORT and irqflags tracing
- timer sync: Add tick timer sync logic
- fix possible deadlock in timer sync, pointed out by mips guys

it together with these patches"

The GICv3 ITS doesn't really depend on PCI. Only the PCI/MSI
part of it does, and there is no reason not to blow away most
of the irqchip stack because PCI is not selected (though not
selecting PCI seem to be asking for punishment, but hey...).
So let's split the PCI-specific part from the ITS in the Kconfig
file, and let's make that part depend on PCI. Architecture specific
hacks (arch/arm{,64}/Kconfig) will be addressed in a separate patch.

If the physical address of the GIC resource cannot be read from device
tree, then the code falls back to reading it from the gcr_gic_base
register. Hopefully this has been set to a sane value by the bootloader
or some platform code, but is defined by the hardware manual to have
"undefined" reset state. Using it as the address at which the GIC will
be mapped into physical memory space can therefore be risky if it has
not been initialised, since it may result in the GIC being mapped to an
effectively random address anywhere in physical memory, where it might
conflict with peripherals or RAM and lead to weird crashes.
Since a "sane value" is very platform specific because it is particular
to the platform's memory map, it is difficult to test for. At the very
least, a warning message should be printed in the case that we trust the
inherited value.

Some systems without proper firmware and/or hardware description data
don't support the split EOI and deactivate operation.
On such systems, we cannot leave the physical interrupt active after the
timer handler on the host has run, so we cannot support KVM with an
in-kernel GIC with the timer changes we are about to introduce.
This patch makes sure that trying to initialize the KVM GIC code will

IPI driver for the Open Multi-Processor Interrupt Controller (ompic) as
described in the Multi-core support section of the OpenRISC 1.2
architecture specification:
https://github.com/openrisc/doc/raw/master/openrisc-arch-1.2-rev0.pdf
Each OpenRISC core contains a full interrupt controller which is used in
the SMP architecture for interrupt balancing. This IPI device, the
ompic, is the only external device required for enabling SMP on
OpenRISC.
Pending ops are stored in a memory bit mask which can allow multiple
pending operations to be set and serviced at a time. This is mostly
borrowed from the alpha IPI implementation.

The gic_set_type() function included writes to the MIPS GIC polarity,
trigger & dual-trigger registers in each case of a switch statement
determining the IRQs type. This is all well & good when we only have a
single cluster & thus a single GIC whose register we want to update. It
will lead to significant duplication once we have multi-cluster support
& multiple GICs to update.
Refactor this such that we determine values for the polarity, trigger &
dual-trigger registers and then have a single set of register writes
following the switch statement. This will allow us to write the same
values to each GIC in a multi-cluster system in a later patch, rather
than needing to duplicate more register writes in each case.

Reserving a number of IPIs based upon the number of VPs reported by the
GIC makes little sense for a few reasons:
- The kernel may have been configured with NR_CPUS less than the number
of VPs in the cluster, in which case using gic_vpes causes us to
reserve more interrupts for IPIs than we will possibly use.
- If a kernel is configured without support for multi-threading & runs
on a system with multi-threading & multiple VPs per core then we'll
similarly reserve more interrupts for IPIs than we will possibly use.
- In systems with multiple clusters the GIC can only provide us with
the number of VPs in its cluster, not across all clusters. In this
case we'll reserve fewer interrupts for IPIs than we need.
Fix these issues by using num_possible_cpus() instead, which in all
cases is actually indicative of how many IPIs we may need.

Rather than configuring EIC mode for all CPUs during boot, configure it
locally on each when they come online. This will become important with
multi-cluster support, since clusters may be powered on & off (for
example via hotplug) and would lose the EIC configuration when powered
off.

We currently walk through the range 0..gic_vpes-1, expecting these
values all to be valid Linux CPU numbers to provide to mips_cm_vp_id(),
and masking all routable local interrupts during boot. This approach has
a few drawbacks:
- In multi-cluster systems we won't have access to all CPU's GIC local
registers when the driver is probed, since clusters (and their GICs)
may be powered down at this point & only brought online later.
- In multi-cluster systems we may power down clusters at runtime, for
example if we offline all CPUs within it via hotplug, and the
cluster's GIC may lose state. We therefore need to reinitialise it
when powering back up, which this approach does not take into
account.
- The range 0..gic_vpes-1 may not all be valid Linux CPU numbers, for
example if we run a kernel configured to support fewer CPUs than the
system it is running on actually has. In this case we'll get garbage
values from mips_cm_vp_id() as we read past the end of the cpu_data
array.
Fix this and simplify the code somewhat by writing an all-bits-set
value to the VP-local reset mask register when a CPU is brought online,
before any local interrupts are configured for it. This removes the need
for us to access all CPUs during driver probe, removing all of the
problems described above.
In the name of simplicity we drop the checks for routability of
interrupts and simply clear the mask bits for all interrupts. Bits for
non-routable local interrupts will have no effect so there's no point
performing extra work to avoid modifying them.

The gic_all_vpes_local_irq_controller chip currently attempts to operate
on all CPUs/VPs in the system when masking or unmasking an interrupt.
This has a few drawbacks:
- In multi-cluster systems we may not always have access to all CPUs in
the system. When all CPUs in a cluster are powered down that
cluster's GIC may also power down, in which case we cannot configure
its state.
- Relatedly, if we power down a cluster after having configured
interrupts for CPUs within it then the cluster's GIC may lose state &
we need to reconfigure it. The current approach doesn't take this
into account.
- It's wasteful if we run Linux on fewer VPs than are present in the
system. For example if we run a uniprocessor kernel on CPU0 of a
system with 16 CPUs then there's no point in us configuring CPUs
1-15.
- The implementation is also lacking in that it expects the range
0..gic_vpes-1 to represent valid Linux CPU numbers which may not
always be the case - for example if we run on a system with more VPs
than the kernel is configured to support.
Fix all of these issues by only configuring the affected interrupts for
CPUs which are online at the time, and recording the configuration in a
new struct gic_all_vpes_chip_data for later use by CPUs being brought
online. We register a CPU hotplug state (reusing
CPUHP_AP_IRQ_GIC_STARTING which the ARM GIC driver uses, and which seems
suitably generic for reuse with the MIPS GIC) and execute
irq_cpu_online() in order to configure the interrupts on the newly
onlined CPU.

The gic_local_irq_domain_map() function has only one callsite in
gic_irq_domain_map(), and the split between the two functions makes it
unclear that they duplicate calculations & checks.
Inline gic_local_irq_domain_map() into gic_irq_domain_map() in order to
clean this up. Doing this makes the following small issues obvious, and
the patch tidies them up:
- Both functions used GIC_HWIRQ_TO_LOCAL() to convert a hwirq number to
a local IRQ number. We now only do this once. Although the compiler
ought to have optimised this away before anyway, the change leaves us
with less duplicate code.
- gic_local_irq_domain_map() had a check for invalid local interrupt
numbers (intr > GIC_LOCAL_INT_FDC). This condition can never occur
because any hwirq higher than those used for local interrupts is a
shared interrupt, which gic_irq_domain_map() already handles
separately. We therefore remove this check.
- The decision of whether to map the interrupt to gic_cpu_pin or
timer_cpu_pin can be handled within the existing switch statement in
gic_irq_domain_map(), shortening the code a little.
The change additionally prepares us nicely for the following patch of
the series which would otherwise need to duplicate the check for whether
a local interrupt should be percpu_devid or just percpu (ie. the switch
statement from gic_irq_domain_map()) in gic_local_irq_domain_map().
