5dc8e4e892 hw/arm: make cpu targeted by arm_load_kernel the primary CPU.
Currently, arm booting processus assumes that the first_cpu is the CPU
that will boot: `arm_load_kernel` is powering off all but the `first_cpu`;
`do_cpu_reset` is setting the loader address only for this `first_cpu`.

For most of the boards, this isn't an issue as the kernel is loaded and
booted on the first CPU anyway. However, for zynqmp, the option
"boot-cpu" allows to choose any CPUs.

Create a new arm_boot_info entry `primary_cpu` recording which CPU will
be boot first. This one is set when `arm_boot_kernel` is called.

bedcc7465d target/arm: Define raw write for PMU CLR registers
Raw writes to PMCNTENCLR and PMCNTENCLR_EL0 incorrectly used their
default write function, which clears written bits instead of writes the
raw value.

PMINTENCLR and PMINTENCLR_EL1 are similar registers, but they instead
had ARM_CP_NO_RAW. Commit 7a0e58fa64 ("target-arm: Split NO_MIGRATE
into ALIAS and NO_RAW") sugguests ARM_CP_ALIAS should be used instead of
ARM_CP_NO_RAW in such a case:

> We currently mark ARM coprocessor/system register definitions with
> the flag ARM_CP_NO_MIGRATE for two different reasons:
> 1) register is an alias on to state that's also visible via
>    some other register, and that other register is the one
>    responsible for migrating the state
> 2) register is not actually state at all (for instance the TLB
>    or cache maintenance operation "registers") and it makes no
>    sense to attempt to migrate it or otherwise access the raw state
>
> This works fine for identifying which registers should be ignored
> when performing migration, but we also use the same functions for
> synchronizing system register state between QEMU and the kernel
> when using KVM. In this case we don't want to try to sync state
> into registers in category 2, but we do want to sync into registers
> in category 1, because the kernel might have picked a different
> one of the aliases as its choice for which one to expose for
> migration.

These registers fall in category 1 (ARM_CP_ALIAS), not category 2
(ARM_CP_NO_RAW).

ARM_CP_NO_RAW also has another undesired side effect that hides
registers from GDB.

Properly set raw write functions and drop the ARM_CP_NO_RAW flag from
PMINTENCLR and PMINTENCLR_EL1; this fixes GDB/KVM state synchronization
of PMCNTENCLR and PMCNTENCLR_EL0, and exposes all these four registers
to GDB.

It is not necessary to add ARM_CP_ALIAS to these registers because the
flag is already set.

e372214e66 qemu-options.hx: Fix reversed description of icount sleep behavior
The documentation for the -icount option incorrectly describes the behavior
of the sleep suboption. Based on the actual implementation and system
behavior, the effects of sleep=on and sleep=off were inadvertently reversed.
This commit updates the description to reflect their intended functionality.

eba1f657cb vfio/container: recover from unmap-all-vaddr failure
If there are multiple containers and unmap-all fails for some container, we
need to remap vaddr for the other containers for which unmap-all succeeded.
Recover by walking all address ranges of all containers to restore the vaddr
for each.  Do so by invoking the vfio listener callback, and passing a new
"remap" flag that tells it to restore a mapping without re-allocating new
userland data structures.

7e9f214113 vfio/container: restore DMA vaddr
In new QEMU, do not register the memory listener at device creation time.
Register it later, in the container post_load handler, after all vmstate
that may affect regions and mapping boundaries has been loaded.  The
post_load registration will cause the listener to invoke its callback on
each flat section, and the calls will match the mappings remembered by the
kernel.

The listener calls a special dma_map handler that passes the new VA of each
section to the kernel using VFIO_DMA_MAP_FLAG_VADDR.  Restore the normal
handler at the end.

c29a65ed68 vfio/container: preserve descriptors
At vfio creation time, save the value of vfio container, group, and device
descriptors in CPR state.  On qemu restart, vfio_realize() finds and uses
the saved descriptors.

During reuse, device and iommu state is already configured, so operations
in vfio_realize that would modify the configuration, such as vfio ioctl's,
are skipped.  The result is that vfio_realize constructs qemu data
structures that reflect the current state of the device.

My contract with Daynix Computing Ltd. will expire by the end of May,
2025. As I may contribute to QEMU for my research, use my email address
at the lab.

As I'm the only maintainer of igb and no longer financially supported to
maintain it, change its status to Odd Fixes until someone steps up.

ec3a7a7150 tests/functional: add memlock tests
Add new tests to check the correctness of the `-overcommit memlock`
option (possible values: off, on, on-fault) by using
`/proc/{qemu_pid}/status` file to check in VmSize, VmRSS and VmLck
values:

* if `memlock=off`, then VmLck = 0;
* if `memlock=on`, then VmLck > 0 and almost all memory is resident;
* if `memlock=on-fault`, then VmLck > 0 and only few memory is resident.

We can simply check for the expected pattern on the console,
no need to wait for two seconds here to search for the pattern
in the log at the end.

While we're at it, also remove the obsolete "timeout" variable
from this test.

b894cc23f8 tests/functional: Use the 'none' machine for the VNC test
The VNC test currently fails if the default machine ("pc" for x86)
has not been compiled into the binary. Since we also can test VNC
when QEMU just shows the default monitor, let's avoid this problem
by simply using the "none" machine (which is always available)
here instead.

 https://docs.travis-ci.com/user/billing-overview/#partner-queue-solution

only s390x and ppc64le are still part of the free OSS tier in Travis.
aarch64 has been removed sometime during the last year. Thus remove
the aarch64 job from our .travis.yml file now to avoid that someone
burns non-OSS CI credits with this job by accident now.
