a5b9621024 aspeed: Remove duplicate typename in AspeedSoCClass
The SoC type name is stored under AspeedSoCClass which is
redundant. Use object_get_typename() instead where needed.

883cc6c578 qemu/atomic: Rename atomic128-ldst.h headers using .h.inc suffix
Since commit 139c1837db ("meson: rename included C source files
to .c.inc"), QEMU standard procedure for included C files is to
use *.c.inc.

Besides, since commit 6a0057aa22 ("docs/devel: make a statement
about includes") this is documented in the Coding Style:

  If you do use template header files they should be named with
  the ``.c.inc`` or ``.h.inc`` suffix to make it clear they are
  being included for expansion.

Therefore rename 'atomic128-ldst.h' as 'atomic128-ldst.h.inc'.

b9e3bf884a include/exec: Split out exec/cpu-interrupt.h
Some of these bits are actually common to all cpus; while the
reset have common reservations for target-specific usage.
While generic code cannot know what the target-specific usage is,
common code can know what to do with the bits, e.g. single-step.

Use a similar terminology smmu_hash_remove_by_sid_range() as the one

smmuv3_invalidate_ste() name is not self explanatory, and introduce a
helper that invokes the g_hash_table_foreach_remove.

f9f99d7ca5 target/arm: Implement SEL2 physical and virtual timers
When FEAT_SEL2 was implemented the SEL2 timers were missed. This
shows up when building the latest Hafnium with SPMC_AT_EL=2. The
actual implementation utilises the same logic as the rest of the
timers so all we need to do is:

  - define the timers and their access functions
  - conditionally add the correct system registers
  - create a new accessfn as the rules are subtly different to the
    existing secure timer

Fixes: e9152ee91c (target/arm: add ARMv8.4-SEL2 system registers)

dfcee1ea4c s390x/pci: add support for guests that request direct mapping
When receiving a guest mpcifc(4) or mpcifc(6) instruction without the T
bit set, treat this as a request to perform direct mapping instead of
address translation.  In order to facilitate this, pin the entirety of
guest memory into the host iommu.

Pinning for the direct mapping case is handled via vfio and its memory
listener.  Additionally, ram discard settings are inherited from vfio:
coordinated discards (e.g. virtio-mem) are allowed while uncoordinated
discards (e.g. virtio-balloon) are disabled.

Subsequent guest DMA operations are all expected to be of the format
guest_phys+sdma, allowing them to be used as lookup into the host
iommu table.

0f66536a01 accel: Forward-declare AccelOpsClass in 'qemu/typedefs.h'
The heavily imported "system/cpus.h" header includes "accel-ops.h"
to get AccelOpsClass type declaration. Reduce headers pressure by
forward declaring it in "qemu/typedefs.h", where we already
declare the AccelCPUState type.

Reduce "system/cpus.h" inclusions by only including
"system/accel-ops.h" when necessary.

b12a0f8566 accel: Rename 'hw/core/accel-cpu.h' -> 'accel/accel-cpu-target.h'
AccelCPUClass is for accelerator to initialize target specific
features of a vCPU. Not really related to hardware emulation,
rename "hw/core/accel-cpu.h" as "accel/accel-cpu-target.h"
(using the explicit -target suffix).

More importantly, target specific header often access the
target specific definitions which are in each target/FOO/cpu.h
header, usually included generically as "cpu.h" relative to
target/FOO/. However, there is already a "cpu.h" in hw/core/
which takes precedence. This change allows "accel-cpu-target.h"
to include a target "cpu.h".

Mechanical change doing:

 $  git mv include/hw/core/accel-cpu.h \
           include/accel/accel-cpu-target.h
 $  sed -i -e 's,hw/core/accel-cpu.h,accel/accel-cpu-target.h,' \
   $(git grep -l hw/core/accel-cpu.h)

and renaming header guard 'ACCEL_CPU_TARGET_H'.
