e844f0c5d0 hw: Replace qemu_or_irq typedef by OrIRQState
OBJECT_DECLARE_SIMPLE_TYPE() macro provides the OrIRQState
declaration for free. Besides, the QOM code style is to use
the structure name as typedef, and QEMU style is to use Camel
Case, so rename qemu_or_irq as OrIRQState.

Mechanical change using:

  $ sed -i -e 's/qemu_or_irq/OrIRQState/g' $(git grep -l qemu_or_irq)

4703f6c2f7 hw/irq: Declare QOM macros using OBJECT_DECLARE_SIMPLE_TYPE()
QOM *DECLARE* macros expect a typedef as first argument,
not a structure. Replace 'struct IRQState' by 'IRQState'
to avoid when modifying the macros:

  ../hw/core/irq.c:29:1: error: declaration of anonymous struct must be a definition
  DECLARE_INSTANCE_CHECKER(struct IRQState, IRQ,
  ^

Use OBJECT_DECLARE_SIMPLE_TYPE instead of DECLARE_INSTANCE_CHECKER.

This struct has no dependencies on TCG code and it is being used in
target/arm/ptw.c to simplify the passing around of page table walk
results. Those routines can be reached by KVM code via the gdbstub
breakpoint code, so take the structure out of CONFIG_TCG to make it
visible when building with --disable-tcg.

e97a9b8ce6 gitlab-ci.d/base: Mark jobs as interruptible by default
When handling pull requests in the staging branch, it often happens
that one of the job fails due to a problem, so that the pull request
can't be merged. Peter/Richard/Stefan then informs the sender of the
pull request and continues by pushing the next pending pull request
from another subsystem maintainer. Now the problem is that there might
still be lots of other running jobs in the pipeline of the first pull
request, eating up precious CI minutes though the pipeline is not
needed anymore. We can avoid this by marking the jobs as "interruptible".
With this setting, the jobs from previous pipelines are automatically
terminated when pushing a new one. If someone does not like this auto-
matic termination, it can still be disabled in the settings of the
repository. See this URL for details:

 https://docs.gitlab.com/ee/ci/yaml/index.html#interruptible

eda2321d7f gitlab-ci.d: Build with --enable-fdt=system by default
By using --enable-fdt=system we can make sure that the configure
script does not try to check out the "dtc" submodule. This should
help to safe some precious CI minutes in the long run.

While we're at it, also drop some now-redundant --enable-slirp
and --enable-capstone statements. These used to have the "=system"
suffix in the past, too, which has been dropped when the their
corresponding submodules had been removed. Since these features
are auto-enabled anyway now (since the containers have the right
libraries installed), we do not need the explicit --enable-...
statements anymore.

adf4c9bd2e meson: fix dependency on qemu-keymap
When qemu-keymap is not available on the host, and enable-xkbcommon
is specified, parallel make fails with:

  % make clean
  ...
  % make -j 32
  ...
  FAILED: pc-bios/keymaps/is
  ./qemu-keymap -f pc-bios/keymaps/is -l is
  /bin/sh: ./qemu-keymap: No such file or directory
  ... many similar messages ...

The code always runs find_program, rather than waiting to build
qemu-keymap, because it looks for CONFIG_XKBCOMMON in config_host
rather than config_host_data.  Making serially succeeds, by soft
linking files from pc-bios/keymaps, but that is not the desired
result for enable-xkbcommon.

Examining all occurrences of 'in config_host' for similar bugs shows one
instance in the docs, which is also fixed here.

c3a073c610 s390x/pv: Add support for asynchronous teardown for reboot
This patch adds support for the asynchronous teardown for reboot for
protected VMs.

When attempting to tear down a protected VM, try to use the new
asynchronous interface first. If that fails, fall back to the classic
synchronous one.

The asynchronous interface involves invoking the new
KVM_PV_ASYNC_DISABLE_PREPARE command for the KVM_S390_PV_COMMAND ioctl.

This will prepare the current protected VM for asynchronous teardown.
Once the protected VM is prepared for teardown, execution can continue
immediately.

Once the protected VM has been prepared, a new thread is started to
actually perform the teardown. The new thread uses the new
KVM_PV_ASYNC_DISABLE command for the KVM_S390_PV_COMMAND ioctl. The
previously prepared protected VM is torn down in the new thread.

Once KVM_PV_ASYNC_DISABLE is invoked, it is possible to use
KVM_PV_ASYNC_DISABLE_PREPARE again. If a protected VM has already been
prepared and its cleanup has not started, it will not be possible to
prepare a new VM. In that case the classic synchronous teardown has to
be performed.

The synchronous teardown will now also clean up any prepared VMs whose
asynchronous teardown has not been initiated yet.

This considerably speeds up the reboot of a protected VM; for large VMs
especially, it could take a long time to perform a reboot with the
traditional synchronous teardown, while with this patch it is almost
immediate.
