hw/intc: riscv-imsic: Fix interrupt state updates.

The IMSIC state variable eistate[] is modified by CSR instructions
within a range dedicated to the local CPU and by MMIO writes from any CPU.
Access to eistate from MMIO accessors is protected by the BQL, but
read-modify-write (RMW) sequences from CSRRW do not acquire the BQL,
making the RMW sequence vulnerable to a race condition with MMIO access
from a remote CPU.

This race can manifest as missing IPI or MSI in multi-CPU systems, eg:

[   43.008092] watchdog: BUG: soft lockup - CPU#2 stuck for 27s! [kworker/u19:1:52]
[   43.011723] CPU: 2 UID: 0 PID: 52 Comm: kworker/u19:1 Not tainted 6.11.0-rc6

[   43.019683] [<ffffffff80010914>] flush_tlb_kernel_range+0x20/0x28

The interrupt line raise/lower sequence was changed to prevent a race
between the evaluation of the eistate and the execution of the qemu_irq
raise/lower, ensuring that the interrupt line is not incorrectly
deactivated based on a stale topei check result. To avoid holding BQL
all modifications of eistate are converted to atomic operations.

block/reqlist: allow adding overlapping requests

Allow overlapping request by removing the assert that made it
impossible. There are only two callers:

1. block_copy_task_create()

It already asserts the very same condition before calling
reqlist_init_req().

2. cbw_snapshot_read_lock()

There is no need to have read requests be non-overlapping in
copy-before-write when used for snapshot-access. In fact, there was no
protection against two callers of cbw_snapshot_read_lock() calling
reqlist_init_req() with overlapping ranges and this could lead to an
assertion failure [1].

In particular, with the reproducer script below [0], two
cbw_co_snapshot_block_status() callers could race, with the second
calling reqlist_init_req() before the first one finishes and removes
its conflicting request.

minimum cluster size used for block-copy operations and thus in
particular also the granularity for discard requests to the source.

The type 'size' (corresponding to uint64_t in C) is used in QAPI to
rule out negative inputs and for consistency with already existing
@cluster-size parameters. Since block_copy_calculate_cluster_size()
uses int64_t for its result, a check that the input is not too large
is added in block_copy_state_new() before calling it. The calculation
in block_copy_calculate_cluster_size() is done in the target int64_t
type.

.gitlab-ci.d: Make separate collapsible log sections for build and test

GitLab lets a CI job create its own collapsible log sections by
emitting special escape codes, as documented here:

https://docs.gitlab.com/ee/ci/yaml/script.html#expand-and-collapse-job-log-sections

Use these to make "configure", "build" and "test" separate
collapsible stages.

As recommended by the GitLab docs, we use some shell which is
sourced in the CI job to define functions to emit the magic
lines that start and end sections, to hide the ugliness of
the printf lines from the log.

.gitlab-ci.d: Split build and test in cross build job templates

In the native_build_job_template we have separate steps in the script
for the build and the test steps.  This is helpful because then
gitlab will give separate timestamps in the log view for each, and
you can see how long it took to compile vs how long to test.  In the
templates in crossbuild-template.yml, however, we do both the build
and test in a single 'make' invocation, and so we don't get the
separate timing information.

Split the build and test, in the same way we do in the native build
template.

This will also give us a place to separate out how parallel we want
to do the build by default from how parallel we want to do the tests
by default, which might be helpful in future.

suspended state. Due to this, the virtio-mem driver in the Linux kernel
disallowed suspend-to-ram requests in the guest when the

when suspending is possible in QEMU (currently only x86).

interface uses ResetState, so ShutdownCause needs to be translated to
ResetType somewhere. Translating it qemu_devices_reset() makes adding
new reset types harder, as they cannot always be matched to a single
ShutdownCause here, and devices may need to check the ResetType to
determine what to reset and if to reset at all.

qemu_system_reset() and updates all MachineClass children to use the

Because of this they cannot be used (yet) with virtio-mmio or virtio-ccw.
In fact the code that is common to virtio-mem and virtio-pmem, which

Without this patch it is possible to create a configuration with
