Pull xen fix from Juergen Gross:
 "A fix for the xen events driver:

  Closing of an event channel in the Linux kernel can result in a
  deadlock. This happens when the close is being performed in parallel
  to an unrelated Xen console action and the handling of a Xen console
  interrupt in an unprivileged guest.

  The closing of an event channel is e.g. triggered by removal of a
  paravirtual device on the other side. As this action will cause
  console messages to be issued on the other side quite often, the
  chance of triggering the deadlock is not negligible"

  xen/events: replace evtchn_rwlock with RCU

Static calls invocations aren't well supported from module __init and
__exit functions. Especially the static call from cleanup_trusted() led
to a crash on x86 kernel with CONFIG_DEBUG_VIRTUAL=y.

However, the usage of static call invocations for trusted_key_init()
and trusted_key_exit() don't add any value from either a performance or
security perspective. Hence switch to use indirect function calls instead.

Note here that although it will fix the current crash report, ultimately
the static call infrastructure should be fixed to either support its
future usage from module __init and __exit functions or not.

Pull irq fixes from Thomas Gleixner:
 "A set of updates for interrupt chip drivers:

   - Fix the fail of the Qualcomm PDC driver on v3.2 hardware which is
     caused by a control bit being moved to a different location

   - Update the SM8150 device tree PDC resource so the version register
     can be read

   - Make the Renesas RZG2L driver correct for interrupts which are
     outside of the LSB in the TSSR register by using the proper macro
     for calculating the mask

   - Document the Renesas RZ2GL device tree binding correctly and update
     them for a few devices which faul to boot otherwise

   - Use the proper accessor in the RZ2GL driver instead of blindly
     dereferencing an unchecked pointer

   - Make GICv3 handle the dma-non-coherent attribute correctly

   - Ensure that all interrupt controller nodes on RISCV are marked as
     initialized correctly

  Maintainer changes:

   - Add a new entry for GIC interrupt controllers and assign Marc
     Zyngier as the maintainer

   - Remove Marc Zyngier from the core and driver maintainer entries as
     he is burried in work and short of time to handle that.

  Thanks to Marc for all the great work he has done in the past couple
  of years!

  Also note that commit 5873d380 ("irqchip/qcom-pdc: Add support for
  v3.2 HW") has a incorrect SOB chain.

  The real author is Neil. His patch was posted by Dmitry once and Neil
  picked it up from the list and reposted it with the bogus SOB chain.

  Not a big deal, but worth to mention. I wanted to fix that up, but
  then got distracted and Marc piled more changes on top. So I decided
  to leave it as is instead of rebasing world"

Ifcfg config file support in NetworkManger is deprecated. This patch
provides support for the new keyfile config format for connection
profiles in NetworkManager. The patch modifies the hv_kvp_daemon code
to generate the new network configuration in keyfile
format(.ini-style format) along with a ifcfg format configuration.
The ifcfg format configuration is also retained to support easy
backward compatibility for distro vendors. These configurations are
stored in temp files which are further translated using the
hv_set_ifconfig.sh script. This script is implemented by individual
distros based on the network management commands supported.
For example, RHEL's implementation could be found here:
https://gitlab.com/redhat/centos-stream/src/hyperv-daemons/-/blob/c9s/hv_set_ifconfig.sh
Debian's implementation could be found here:
https://github.com/endlessm/linux/blob/master/debian/cloud-tools/hv_set_ifconfig

The next part of this support is to let the Distro vendors consume
these modified implementations to the new configuration format.

In unprivileged Xen guests event handling can cause a deadlock with
Xen console handling. The evtchn_rwlock and the hvc_lock are taken in
opposite sequence in __hvc_poll() and in Xen console IRQ handling.
Normally this is no problem, as the evtchn_rwlock is taken as a reader
in both paths, but as soon as an event channel is being closed, the
lock will be taken as a writer, which will cause read_lock() to block:

CPU0                     CPU1                CPU2
(IRQ handling)           (__hvc_poll())      (closing event channel)

read_lock(evtchn_rwlock)
                         spin_lock(hvc_lock)
                                             write_lock(evtchn_rwlock)
                                                 [blocks]
spin_lock(hvc_lock)
    [blocks]
                        read_lock(evtchn_rwlock)
                            [blocks due to writer waiting,
                             and not in_interrupt()]

This issue can be avoided by replacing evtchn_rwlock with RCU in
xen_free_irq(). Note that RCU is used only to delay freeing of the
irq_info memory. There is no RCU based dereferencing or replacement of
pointers involved.

In order to avoid potential races between removing the irq_info
reference and handling of interrupts, set the irq_info pointer to NULL
only when freeing its memory. The IRQ itself must be freed at that
time, too, as otherwise the same IRQ number could be allocated again
before handling of the old instance would have been finished.

This is XSA-441 / CVE-2023-34324.

  parisc: Restore __ldcw_align for PA-RISC 2.0 processors
  parisc: Fix crash with nr_cpus=1 option

Back in 2005, Kyle McMartin removed the 16-byte alignment for
ldcw semaphores on PA 2.0 machines (CONFIG_PA20). This broke
spinlocks on pre PA8800 processors. The main symptom was random
faults in mmap'd memory (e.g., gcc compilations, etc).

Unfortunately, the errata for this ldcw change is lost.

The issue is the 16-byte alignment required for ldcw semaphore
instructions can only be reduced to natural alignment when the
ldcw operation can be handled coherently in cache. Only PA8800
and PA8900 processors actually support doing the operation in
cache.

Aligning the spinlock dynamically adds two integer instructions
to each spinlock.

Tested on rp3440, c8000 and a500.

It is pretty obvious that I haven't done much on the IRQ side
for a while, and it is unlikely that I'll have more bandwidth
for it any time soon. People keep sending me patches that
I end-up reviewing in a cursory manner, which isn't great for
anyone.

So in everyone's interest, I'm removing myself from the list
of maintainers and leave the irqchip and irqdomain subsystems
in Thomas' capable hands.

It is unlikely that anyone is mad enough to pick this up,
so I'll keep doing that for the foreseable future.

The STM32F4/7 EXTI driver was missing the xlate callback, so IRQ trigger
flags specified in the device tree were being ignored. This was
preventing the RTC alarm interrupt from working, because it must be set
to trigger on the rising edge to function correctly.

The RISC-V INTC local interrupts are per-HART (or per-CPU) so we
create INTC IRQ domain only for the INTC node belonging to the boot
HART. This means only the boot HART INTC node will be marked as
initialized and other INTC nodes won't be marked which results
downstream interrupt controllers (such as PLIC, IMSIC and APLIC
direct-mode) not being probed due to missing device suppliers.

To address this issue, we mark all INTC node for which we don't
create IRQ domain as initialized.

The GIC architecture specification defines a set of registers
for redistributors and ITSes that control the sharebility and
cacheability attributes of redistributors/ITSes initiator ports
on the interconnect (GICR_[V]PROPBASER, GICR_[V]PENDBASER,
GITS_BASER<n>).

Architecturally the GIC provides a means to drive shareability
and cacheability attributes signals and related IWB/OWB/ISH barriers
but it is not mandatory for designs to wire up the corresponding
interconnect signals that control the cacheability/shareability
of transactions.

Redistributors and ITSes interconnect ports can be connected to
non-coherent interconnects that are not able to manage the
shareability/cacheability attributes; this implicitly makes
the redistributors and ITSes non-coherent observers.

So far, the GIC driver on probe executes a write to "probe" for
the redistributors and ITSes registers shareability bitfields
by writing a value (ie InnerShareable - the shareability domain the
CPUs are in) and check it back to detect whether the value sticks or
not; this hinges on a GIC programming model behaviour that predates the
current specifications, that just define shareability bits as writeable
but do not guarantee that writing certain shareability values
enable the expected behaviour for the redistributors/ITSes
memory interconnect ports.

To enable non-coherent GIC designs, introduce the "dma-noncoherent"
device tree property to allow firmware to describe redistributors and
ITSes as non-coherent observers on the memory interconnect and use the
property to force the shareability attributes to be programmed into the
redistributors and ITSes registers through the GIC quirks mechanism.

In order to pave the way for more fancy quirk handling without making
more of a mess of this terrible driver, split the allocation of the
ITS descriptor (its_node) from the actual probing.

This will allow firmware-specific hooks to be added between these
two points.

The GIC v3 specifications allow redistributors and ITSes interconnect
ports used to access memory to be wired up in a way that makes the
respective initiators/memory observers non-coherent.

Add the standard dma-noncoherent property to the GICv3 bindings to
allow firmware to describe the redistributors/ITSes components and
interconnect ports behaviour in system designs where the redistributors
and ITSes are not coherent with the CPU.

Document RZ/G2UL (R9A07G043U) IRQC bindings. The IRQC block on RZ/G2UL SoC
is almost identical to one found on the RZ/G2L SoC the only difference
being it can support BUS_ERR_INT for which it has additional registers.
Hence new generic compatible string "renesas,r9a07g043u-irqc" is added
for RZ/G2UL SoC.

Now that we have additional interrupt for RZ/G2UL and RZ/Five SoC
interrupt-names property is added so that we can parse them based on
names.

While at it updated the example node to four spaces and added
interrupt-names property.

The 'msi' child node schema is missing constraints on additional properties.
It turns out it is incomplete and properties for it are documented in the
parent node by mistake. Move the reference to msi-controller.yaml and
the custom properties to the 'msi' node. Adding 'unevaluatedProperties'
ensures all the properties in the 'msi' node are documented.

With the schema corrected, a minimal interrupt controller node is needed
to properly decode the interrupt properties since the example has
multiple interrupt parents.
