The meson rules were excluding the pbkdf crypto test when gnutls was the
crypto backend. It was then excluded again in #if statements in the test
file.
Rather than update these conditions, remove them all, and use the result
of the qcrypto_pbkdf_supports() function to determine whether to skip
test registration.

Both gnutls and gcrypt can be configured to exclude support for certain
algorithms via a runtime check against system crypto policies. Thus it
is not sufficient to have a compile time test for hash support in their
pbkdf implementations.

CPU time accounting in the kernel has been demonstrated to have a
sawtooth pattern[1][2]. This can cause the getrusage system call to
not be as accurate as we are expecting, which can cause this calculation
to stall.
The kernel discussions shows that this inaccuracy happens when CPU time
gets big enough, so this patch changes qcrypto_pbkdf2_count_iters to run
in a fresh thread to avoid this inaccuracy. It also adds a sanity check
to fail the process if CPU time is not accounted.

The TYPE_NUBUS_DEVICE class lets the user specify the nubus slot
using an int32 "slot" QOM property. Its realize method doesn't do
any range checking on this value, which Coverity notices by way of
the possibility that 'nd->slot * NUBUS_SUPER_SLOT_SIZE' might
overflow the 32-bit arithmetic it is using.
Constrain the slot value to be less than NUBUS_SLOT_NB (16).

In m5208_sys_read(), we have a loop of n from 0 to 31, and we
calculate (2u << n). For the n == 31 iteration this will shift off
the top of the unsigned 32 bit integer.
This is harmless, because we're going to stop the loop with n == 31
anyway, but we can avoid the error by using 64-bit arithmetic here.
(The SDCS0 register is documented at
https://www.nxp.com/docs/en/reference-manual/MCF5208RM.pdf
section 18.4.5; we want the lower 5 bits to indicate the
RAM size, where 31 == 4GB, 30 == 2GB, and so on down.
As it happens, the layout of the mcf5208evb board memory map
means it doesn't make sense to have more than 1GB of RAM
in any case.)

In the dm163-test and stm32l4x5_usart-test, a couple of subtests are
missing the qtest_quit() call. The effect of this is that on hosts
other than Linux and FreeBSD the test will timeout after executing
all the tests:
242/845 qemu:qtest+qtest-arm / qtest-arm/dm163-test TIMEOUT 60.04s 3 subtests passed
100/845 qemu:qtest+qtest-arm / qtest-arm/stm32l4x5_usart-test TIMEOUT 600.02s 5 subtests passed
This happens because the qemu-system-arm binary which the test
starts does not exit, and because it shares the stdout with the
test binary, the overall meson test harness thinks the test is
still running. On Linux and FreeBSD we have an extra safety net
set up in qtest_spawn_qemu() which kills off any QEMU binary that
ends up without a parent. This is intended for the case where
QEMU crashed and didn't respond to a SIGTERM or polite request
to quit, but it also sidestepped the problem in this case.
However, OpenBSD doesn't have a PDEATHSIG equivalent, so we
see the timeouts when running a 'make vm-build-openbsd' run.
Add the missing qtest_quit() calls.

In vfp.decode we have the names of the VFNMA and VFNMS instructions
the wrong way around. The architecture says that bit 6 is the 'op'
bit, which is 1 for VFNMA and 0 for VFNMS, but we label these two
lines of decode the other way around. This doesn't cause any
user-visible problem because in the handling of these functions in
translate-vfp.c we give VFNMA the behaviour specified for VFNMS and
vice-versa, but it's confusing when reading the code.
Switch the names of the VFP VFNMA and VFNMS instructions in
the decode file and flip the behaviour also.
NB: the instructions VFMA and VFMS *are* decoded with op=0 for
VFMA and op=1 for VFMS; the confusion probably arose because
we assumed VFNMA and VFNMS to be the same way around.

Now that our SMMU model supports enabling both stages of translation
at once, we can enable this in the sbsa-ref board. Existing guest
code that only programs stage 1 and doesn't care about stage 2 should
continue to run with the same behaviour, but guests that do want to
do nested SMMU configurations can now do so.

Now that our SMMU model supports enabling both stages of translation
at once, we can enable this in the virt board. This is no change in
behaviour for guests, because if they simply ignore stage 2 and never
configure it then it has no effect. For the usual backwards
compatibility reasons we enable this only for machine types starting
with 9.2.
(Note that the SMMU is disabled by default on the virt board and is
only created if the user passes the 'iommu=smmuv3' machine option.)

The main loop in rr_cpu_thread_fn() can never terminate, so the
code at the end of the function to clean up the RCU subsystem is
dead code. Replace it with g_assert_not_reached().
(This is different from the other cpu_thread_fn for e.g. MTTCG or
for the KVM accelerator -- those can exit, if the vCPU they
are responsible for is unplugged. But the RR cpu thread fn
handles all CPUs in the system in a round-robin way, so even
if one is unplugged it keeps looping.)

Implement the FPCR.EBF=1 semantics for bfdotadd() operations:
* is_ebf() sets up fpst and fpst_odd
* bfdotadd_ebf() implements the fused paired-multiply-and-add
operation that we need
The paired-multiply-and-add is similar to f16_dotadd() and
we use the same trick here as in that function, but the inputs
here are bfloat16 rather than float16.

We use bfdotadd() in four callsites for various helper functions. Currently
this all assumes that we have the FPCR.EBF=0 semantics. For FPCR.EBF=1
we will need to:
* call a different routine to bfdotadd() because we need to do a
fused multiply-add rather than separate multiply and add steps
* use a different float_status that honours the FPCR rounding mode
and denormal-flushing fields
* pass in an extra float_status that has been set up to perform
round-to-odd rounding
To prepare for this, refactor all the callsites so that instead of
for (...) {
x = bfdotadd(...);
}
they are:
float_status fpst, fpst_odd;
if (is_ebf(env, &fpst, &fpst_odd)) {
for (...) {
x = bfdotadd_ebf(..., &fpst, &fpst_odd);
}
} else {
for (...) {
x = bfdotadd(..., &fpst);
}
}
For the moment the is_ebf() function always returns false, sets up
fpst for EBF=0 semantics and never sets up fpst_odd; bfdotadd_ebf()
will assert if called. We'll fill in the handling for EBF=1 in the
next commit.
This change should be a zero-behaviour-change refactor.

FEAT_EBF16 adds one new bit to the FPCR floating point control
register. Allow this bit to be read and written when the ID
registers indicate the presence of the feature.
Note that because this new bit is not in FPSCR_FPCR_MASK the bit is
not visible in the AArch32 FPSCR, and FPSCR writes do not affect it.

We've been creating the virtio-mmio devices in forwards order
but since the qbus lists prepend (rather than append) entries,
the virtio busses end up with decreasing base address order.
Xen enables virtio-mmio nodes in forwards order so there's been
a missmatch. So far, we've been working around this with an
out-of-tree patch to Xen.
This reverses the order making sure the virtio busses end up
ordered with increasing base addresses avoiding the need to
patch Xen.
