s390x/pci: Fix endianness for zPCI BAR values.
During zPCI scan, BAR configuration data retrieved via CLP Query was
misinterpreted due to an endianness mismatch between QEMU and the guest
kernel.
The guest kernel's clp_store_query_pci_fn() expects BAR values in
little-endian format and converts them with le32_to_cpu(). However, QEMU
was incorrectly sending them in big-endian format, not following the
architecture specification. This caused incorrect bit-swapping in the
kernel, leading zpci_setup_bus_resources() to perform registration checks
against invalid flags, making the process ineffective.
Observation values for zPCI device (NVMe passthrough):
LPAR from real CLP:
[ 0.865595] Resource: PCI Bus 0000:00 -> zdev->bar[0].val: 0x4

Revert "rcu: Unify force quiescent state"
This reverts commit 55d98e3edeeb17dd8445db27605d2b34f4c3ba85.
The commit introduced a regression in the replay functional test
on alpha (tests/functional/alpha/test_replay.py), that causes CI
failures regularly. Thus revert this change until someone has
figured out what is going wrong here.

Log Message:
-----------
fpu: Restrict parts_round_to_int_normal to target precision
Currently parts_round_to_int_normal() assumes that its input has just
been unpacked and therefore doesn't expect non-zero fraction bits past
target precision.
The upcoming DIVIDE TO INTEGER use cases needs it to support
calculations on intermediate values that utilize all fraction bits,
while at the same time restricting the result's precision to frac_size.
Delete the "All integral" check, because even though really large
values are always integer, their low fraction bits still need to be
truncated. For the same reason, make sure rnd_mask covers at least
fraction bits past target precision.

target/s390x: Implement DIVIDE TO INTEGER
DIVIDE TO INTEGER computes floating point remainder and is used by

Put the main logic into fpu/, because it is way more convenient to
operate on FloatParts than to convert floats back-and-forth.

tests/Makefile.include: add run-tcg-tests-TARGET to check-help
User can execute TCG tests for a specific TARGET using the command:
$ make run-tcg-tests-TARGET-softmmu
However, this command is not showing in 'make check-help'
documentation, making it hard for new contributors to
discover.
This commit help to resolve this by adding the description
for the command, to the "check-tcg" section, as suggested
by Thomas, in tests/Makefile.include.
Additionally, reformat the alignment to accommodate
the length of the new command, ensuring the
consistency of the output.

pkg_resources has been fully dropped from modern pip/setuptools

by itself, repair most GitLab CI tests upstream; with the exception of
tox tests which are still making use of avocado - which will be dropped
in a separate series to restore functionality there.
