Hi; some minor changes for 6.2, which I think can be classified
as bug fixes and are OK for this point in the release cycle.
(Wouldn't be the end of the world if they slipped to 7.0.)

[PULL 1/4] hw/intc/arm_gicv3: Move checking of redist-region-count to arm_gicv3_common_realize

[Peter Maydell]

The GICv3 devices have an array property redist-region-count.
Currently we check this for errors (bad values) in
gicv3_init_irqs_and_mmio(), just before we use it.  Move this error
checking to the arm_gicv3_common_realize() function, where we
sanity-check all of the other base-class properties. (This will
always be before gicv3_init_irqs_and_mmio() is called, because
that function is called in the subclass realize methods, after
they have called the parent-class realize.)

The motivation for this refactor is:
 * we would like to use the redist_region_count[] values in
   arm_gicv3_common_realize() in a subsequent patch, so we need
   to have already done the sanity-checking first
 * this removes the only use of the Error** argument to
   gicv3_init_irqs_and_mmio(), so we can remove some error-handling
   boilerplate

[PULL 2/4] hw/intc/arm_gicv3: Set GICR_TYPER.Last correctly when nb_redist_regions > 1

[Peter Maydell]

The 'Last' bit in the GICR_TYPER GICv3 redistributor register is
supposed to be set to 1 if this is the last redistributor in a series
of contiguous redistributor pages.  Currently we set Last only for
the redistributor for CPU (num_cpu - 1).  This only works if there is
a single redistributor region; if there are multiple redistributor
regions then we need to set the Last bit for the last redistributor
in each region.

This doesn't cause any problems currently because only the KVM GICv3
supports multiple redistributor regions, and it ignores the value in
GICv3State::gicr_typer.  But we need to fix this before we can enable
support for multiple regions in the emulated GICv3.

[PULL 3/4] hw/intc/arm_gicv3: Support multiple redistributor regions

[Peter Maydell]

Our GICv3 QOM interface includes an array property
redist-region-count which allows board models to specify that the
registributor registers are not in a single contiguous range, but
split into multiple pieces.  We implemented this for KVM, but
currently the TCG GICv3 model insists that there is only one region.
You can see the limit being hit with a setup like:
  qemu-system-aarch64 -machine virt,gic-version=3 -smp 124

Add support for split regions to the TCG GICv3.  To do this we switch
from allocating a simple array of MemoryRegions to an array of
GICv3RedistRegion structs so that we can use the GICv3RedistRegion as
the opaque pointer in the MemoryRegion read/write callbacks.  Each
GICv3RedistRegion contains the MemoryRegion, a backpointer allowing
the read/write callback to get hold of the GICv3State, and an index
which allows us to calculate which CPU's redistributor is being
accessed.

Note that arm_gicv3_kvm always passes in NULL as the ops argument
to gicv3_init_irqs_and_mmio(), so the only MemoryRegion read/write
callbacks we need to update to handle this new scheme are the
gicv3_redist_read/write functions used by the emulated GICv3.

[PULL 4/4] hw/rtc/pl031: Send RTC_CHANGE QMP event

[Peter Maydell]

From: Eric Auger <eric.auger@redhat.com>

The PL031 currently is not able to report guest RTC change to the QMP
monitor as opposed to mc146818 or spapr RTCs. This patch adds the call
to qapi_event_send_rtc_change() when the Load Register is written. The
value which is reported corresponds to the difference between the guest
reference time and the reference time kept in softmmu/rtc.c.

For instance adding 20s to the guest RTC value will report 20. Adding
an extra 20s to the guest RTC value will report 20 + 20 = 40.

The inclusion of qapi/qapi-types-misc-target.h in hw/rtl/pl031.c
require to compile the PL031 with specific_ss.add() to avoid
./qapi/qapi-types-misc-target.h:18:13: error: attempt to use poisoned
"TARGET_<ARCH>".
