d7f39c40eb irqchip/bcm2836: Fix IPI acknowledgement after conversion to handle_percpu_devid_irq 
It appears that despite its name, the bcm2836_arm_irqchip_ipi_eoi()
callback is an acknowledgement, and not an EOI. This means that
we lose IPIs that are made pending between the handling of the
IPI and the write to LOCAL_MAILBOX0_CLR0. With the right timing,
things fail nicely.

This used to work with handle_percpu_devid_fasteoi_ipi(), which
started by eoi-ing the interrupt. With the standard fasteoi flow,
this doesn't work anymore.

So let's use this callback for what it is, an ack. Your favourite
RPi-2/3 is back up and running.

06fde695ee genirq/msi: Initialize msi_alloc_info before calling msi_domain_prepare_irqs() 
Since commit 5fe71d271d ("irqchip/gic-v3-its: Tag ITS device as shared if
allocating for a proxy device"), some of the devices are wrongly marked as
"shared" by the ITS driver on systems equipped with the ITS(es). The
problem is that the @info->flags may not be initialized anywhere and we end
up looking at random bits on the stack. That's obviously not good.

We can perform the initialization in the IRQ core layer before calling
msi_domain_prepare_irqs(), which is neat enough.

2f5fbc4305 irqchip/qcom-pdc: Fix phantom irq when changing between rising/falling 
We have a problem if we use gpio-keys and configure wakeups such that
we only want one edge to wake us up.  AKA:
  wakeup-event-action = <EV_ACT_DEASSERTED>;
  wakeup-source;

Specifically we end up with a phantom interrupt that blocks suspend if
the line was already high and we want wakeups on rising edges (AKA we
want the GPIO to go low and then high again before we wake up).  The
opposite is also problematic.

Specifically, here's what's happening today:
1. Normally, gpio-keys configures to look for both edges.  Due to the
   current workaround introduced in commit c3c0c2e18d ("pinctrl:
   qcom: Handle broken/missing PDC dual edge IRQs on sc7180"), if the
   line was high we'd configure for falling edges.
2. At suspend time, we change to look for rising edges.
3. After qcom_pdc_gic_set_type() runs, we get a phantom interrupt.

We can solve this by just clearing the phantom interrupt.

NOTE: it is possible that this could cause problems for a client with
very specific needs, but there's not much we can do with this
hardware.  As an example, let's say the interrupt signal is currently
high and the client is looking for falling edges.  The client now
changes to look for rising edges.  The client could possibly expect
that if the line has a short pulse low (and back high) that it would
always be detected.  Specifically no matter when the pulse happened,
it should either have tripped the (old) falling edge trigger or the
(new) rising edge trigger.  We will simply not trip it.  We could
narrow down the race a bit by polling our parent before changing
types, but no matter what we do there will still be a period of time
where we can't tell the difference between a real transition (or more
than one transition) and the phantom.

e15f2fa959 driver core: platform: Add devm_platform_get_irqs_affinity() 
Drivers for multi-queue platform devices may also want managed interrupts
for handling HW queue completion interrupts, so add support.

The function accepts an affinity descriptor pointer, which covers all IRQs
expected for the device.

The function is devm class as the only current in-tree user will also use
devm method for requesting the interrupts; as such, the function is made
as devm as it can ensure ordering of freeing the irq and disposing of the
mapping.

1d3aec8928 genirq/affinity: Add irq_update_affinity_desc() 
Add a function to allow the affinity of an interrupt be switched to
managed, such that interrupts allocated for platform devices may be
managed.

This new interface has certain limitations, and attempts to use it in the
following circumstances will fail:
- For when the kernel is configured for generic IRQ reservation mode (in
  config GENERIC_IRQ_RESERVATION_MODE). The reason being that it could
  conflict with managed vs. non-managed interrupt accounting.
- The interrupt is already started, which should not be the case during
  init
- The interrupt is already configured as managed, which means double init

91f90daa4f platform-msi: Track shared domain allocation 
We have two flavours of platform-MSI:

- MSIs generated by devices for themselves (the usual case)

- MSIs generated on behalf of other devices, as the generating
  device is some form of bridge (either a wire-to-MSI bridge,
  or even a non-transparent PCI bridge that repaints the PCI
  requester ID).

In the latter case, the underlying interrupt architecture may need
to track this in order to keep the mapping alive even when no MSI
are currently being generated.

Add a set of flags to the generic msi_alloc_info_t structure, as
well as the MSI_ALLOC_FLAGS_PROXY_DEVICE flag that will get
advertized by the platform-MSI code when allocating an irqdomain
for a device.

fc6c7cd387 irqchip/ti-sci-intr: Fix freeing of irqs 
ti_sci_intr_irq_domain_free() assumes that out_irq of intr is stored in
data->chip_data and uses it for calling ti_sci irq_free() and then
mark the out_irq as available resource. But ti_sci_intr_irq_domain_alloc()
is storing p_hwirq(parent's hardware irq) which is translated from out_irq.
This is causing resource leakage and eventually out_irq resources might
be exhausted. Fix ti_sci_intr_irq_domain_alloc() by storing the out_irq
in data->chip_data.

6abbd69889 irqchip/gic, gic-v3: Make SGIs use handle_percpu_devid_irq() 
handle_percpu_devid_fasteoi_ipi() states:

 * The biggest difference with the IRQ version is that the interrupt is
 * EOIed early, as the IPI could result in a context switch, and we need to
 * make sure the IPI can fire again

All that can actually happen scheduler-wise within the handling of an IPI
is the raising of TIF_NEED_RESCHED (and / or folding thereof into
preempt_count); see scheduler_ipi() or sched_ttwu_pending() for instance.

Said flag / preempt_count is evaluated some time later before returning to
whatever context was interrupted, and this gates a call to
preempt_schedule_irq() (arm64_preempt_schedule_irq() in arm64).

Per the above, SGI's do not need a different handler than PPI's, so make
them use the same (handle_percpu_devid_irq).

aae5ab854e RISC-V Fixes for 5.10-rc6 
I've collected a handful of fixes over the past few weeks:
 
 * A fix to un-break the build-id argument to the vDSO build, which is necessary
   for the LLVM linker.
 * A fix to initialize the jump label subsystem, without which it (and all the
   stuff that uses it) doesn't actually function.
 * A fix to include <asm/barrier.h> from <vdso/processor.h>, without which some
   drivers won't compile.
 
 I know it's the holidays, but I had some hiccups getting this tested earlier
 this week so it's just going out now.  None of these are tremendously urgent,
 so if they don't make rc6 it's not a big deal.  I'll have some more fixes
 coming next week either way.

ca579827c9 perf tools for v5.10: 4th batch 
- Fix die_entrypc() when DW_AT_ranges DWARF attribute not available.
 
 - Cope with broken DWARF (missing DW_AT_declaration) generated by some recent
   gcc versions.
 
 - Do not generate CGROUP metadata events when not asked to in 'perf record'.
 
 - Use proper CPU for shadow stats in 'perf stat'.
 
 - Update copy of libbpf's hashmap.c, silencing tools/perf build warning.
 
 - Fix return value in 'perf diff'.
 
 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
 
 Test results:
 
 The first ones are container based builds of tools/perf with and without libelf
 support.  Where clang is available, it is also used to build perf with/without
 libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
 when clang and its devel libraries are installed.
 
 The objtool and samples/bpf/ builds are disabled now that I'm switching from
 using the sources in a local volume to fetching them from a http server to
 build it inside the container, to make it easier to build in a container cluster.
 Those will come back later.
 
 Several are cross builds, the ones with -x-ARCH and the android one, and those
 may not have all the features built, due to lack of multi-arch devel packages,
 available and being used so far on just a few, like
 debian:experimental-x-{arm64,mipsel}.
 
 The 'perf test' one will perform a variety of tests exercising
 tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
 with a variety of command line event specifications to then intercept the
 sys_perf_event syscall to check that the perf_event_attr fields are set up as
 expected, among a variety of other unit tests.
 
 Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
 with a variety of feature sets, exercising the build with an incomplete set of
 features as well as with a complete one. It is planned to have it run on each
 of the containers mentioned above, using some container orchestration
 infrastructure. Get in contact if interested in helping having this in place.

76dc2bfc2e Raw NAND changes: 
* Because of a recent change in the core, NAND controller drivers
   initializing the ECC engine too early in the probe path are
   broken. Drivers should wait for the NAND device to be discovered and
   its memory layout known before doing any ECC related initialization,
   so instead of reverting the faulty change which is actually moving
   in the right direction, let's fix the drivers directly: socrates,
   sharpsl, r852, plat_nand, pasemi, tmio, txx9ndfmc, orion, mpc5121,
   lpc32xx_slc, lpc32xx_mlc, fsmc, diskonchip, davinci, cs553x, au1550,

Merge tag 'mtd/fixes-for-5.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux

Pull mtd fixes from Miquel Raynal:
 "Because of a recent change in the core, NAND controller drivers
  initializing the ECC engine too early in the probe path are broken.

  Drivers should wait for the NAND device to be discovered and its
  memory layout known before doing any ECC related initialization, so
  instead of reverting the faulty change which is actually moving in the
  right direction, let's fix the drivers directly: socrates, sharpsl,
  r852, plat_nand, pasemi, tmio, txx9ndfmc, orion, mpc5121, lpc32xx_slc,
  lpc32xx_mlc, fsmc, diskonchip, davinci, cs553x, au1550, ams-delta,
  xway and gpio"
