27221b69a3 s390x: introduce s390_get_memory_limit()
Let's add s390_get_memory_limit(), to query what has been successfully
set via s390_set_memory_limit(). Allow setting the limit only once.

We'll remember the limit in the machine state. Move
s390_set_memory_limit() to machine code, merging it into
set_memory_limit(), because this really is a machine property.

3c6fb557d2 s390x/s390-virtio-ccw: move setting the maximum guest size from sclp to machine code
Nowadays, it feels more natural to have that code located in
s390_memory_init(), where we also have direct access to the machine
object.

While at it, use the actual RAM size, not the maximum RAM size which
cannot currently be reached without support for any memory devices.
Consequently update s390_pv_vm_try_disable_async() to rely on the RAM size
as well, to avoid temporary issues while we further rework that
handling.

set_memory_limit() is temporary, we'll merge it with
s390_set_memory_limit() next.

6e9cc2da4e s390x/s390-virtio-hcall: prepare for more diag500 hypercalls
Let's generalize, abstracting the virtio bits. diag500 is now a generic
hypercall to handle QEMU/KVM specific things. Explicitly specify all
already defined subcodes, including legacy ones (so we know what we can
use for new hypercalls).

Move the PGM_SPECIFICATION injection into the renamed function
handle_diag_500(), so we can turn it into a void function.

We'll rename the files separately, so git properly detects the rename.

4be0fce498 s390x/s390-virtio-hcall: remove hypercall registration mechanism
Nowadays, we only have a single machine type in QEMU, everything is based
on virtio-ccw and the traditional virtio machine does no longer exist. No
need to dynamically register diag500 handlers. Move the two existing
handlers into s390-virtio-hcall.c.

14e568ab48 s390x/s390-virtio-ccw: don't crash on weird RAM sizes
KVM is not happy when starting a VM with weird RAM sizes:

  # qemu-system-s390x --enable-kvm --nographic -m 1234K
  qemu-system-s390x: kvm_set_user_memory_region: KVM_SET_USER_MEMORY_REGION
    failed, slot=0, start=0x0, size=0x244000: Invalid argument
  kvm_set_phys_mem: error registering slot: Invalid argument
  Aborted (core dumped)

Let's handle that in a better way by rejecting such weird RAM sizes
right from the start:

  # qemu-system-s390x --enable-kvm --nographic -m 1234K
  qemu-system-s390x: ram size must be multiples of 1 MiB

713484d038 virtio-mem: unplug memory only during system resets, not device resets
We recently converted from the LegacyReset to the new reset framework
in commit c009a311e9 ("virtio-mem: Use new Resettable framework instead
of LegacyReset") to be able to use the ResetType to filter out wakeup
resets.

However, this change had an undesired implications: as we override the
Resettable interface methods in VirtIOMEMClass, the reset handler will
not only get called during system resets (i.e., qemu_devices_reset())
but also during any direct or indirect device rests (e.g.,
device_cold_reset()).

Further, we might now receive two reset callbacks during
qemu_devices_reset(), first when reset by a parent and later when reset
directly.

The memory state of virtio-mem devices is rather special: it's supposed to
be persistent/unchanged during most resets (similar to resetting a hard
disk will not destroy the data), unless actually cold-resetting the whole
system (different to a hard disk where a reboot will not destroy the data):
ripping out system RAM is something guest OSes don't particularly enjoy,
but we want to detect when rebooting to an OS that does not support
virtio-mem and wouldn't be able to detect+use the memory -- and we want
to force-defragment hotplugged memory to also shrink the usable device
memory region. So we rally want to catch system resets to do that.

On supported targets (e.g., x86), getting a cold reset on the
device/parent triggers is not that easy (but looks like PCI code
might trigger it), so this implication went unnoticed.

However, with upcoming s390x support it is problematic: during
kdump, s390x triggers a subsystem reset, ending up in
s390_machine_reset() and calling only subsystem_reset() instead of
qemu_devices_reset() -- because it's not a full system reset.

In subsystem_reset(), s390x performs a device_cold_reset() of any
TYPE_VIRTUAL_CSS_BRIDGE device, which ends up resetting all children,
including the virtio-mem device. Consequently, we wrongly detect a system
reset and unplug all device memory, resulting in hotplugged memory not
getting included in the crash dump -- undesired.

We really must not mess with hotplugged memory state during simple
device resets. To fix, create+register a new reset object that will only
get triggered during qemu_devices_reset() calls, but not during any other
resets as it is logically not the child of any other object.

68df8c8dba accel/tcg: Include missing 'exec/translation-block.h' header
TB compile flags, tb_page_addr_t type, tb_cflags() and few
other methods are defined in "exec/translation-block.h".

All these files don't include "exec/translation-block.h" but
include "exec/exec-all.h" which include it. Explicitly include
"exec/translation-block.h" to be able to remove it from
"exec/exec-all.h" later when it won't be necessary. Otherwise
we'd get errors such:

a6c0102a86 linux-user/aarch64: Include missing 'user/abitypes.h' header
arm_set_mte_tcf0() uses the abi_long type which is defined
in "user/abitypes.h". Include it in order to avoid when
refactoring:

  In file included from ../../target/arm/gdbstub64.c:28:
  ../linux-user/aarch64/mte_user_helper.h:30:42: error: unknown type name ‘abi_long’; did you mean ‘u_long’?
     30 | void arm_set_mte_tcf0(CPUArchState *env, abi_long value);
        |                                          ^~~~~~~~
