If you are building only with either the new rx-softmmu or avr-softmmu
target, "make check-block" fails a couple of tests since there is no
default machine defined in these new targets. We have to select a machine
in the "check" script for these, just like we already do for the arm- and
tricore-softmmu targets.

We should check whether the user-specified node-name actually refers to
a node. The simplest way to do that is to use bdrv_lookup_bs() instead
of bdrv_find_node() (the former wraps the latter, and produces an error

Quoting ISO C99 6.7.8p4, "All the expressions in an initializer for an
object that has static storage duration shall be constant expressions or
string literals".
The compound literal produced by the make_floatx80() macro is not such a
constant expression, per 6.6p7-9. (An implementation may accept it,
according to 6.6p10, but is not required to.)
Therefore using "floatx80_zero" and make_floatx80() for initializing
"f2xm1_table" and "fpatan_table" is not portable. And gcc-4.8 in RHEL-7.6
actually chokes on them:
> target/i386/fpu_helper.c:871:5: error: initializer element is not constant
> { make_floatx80(0xbfff, 0x8000000000000000ULL),
> ^
We've had the make_floatx80_init() macro for this purpose since commit
3bf7e40ab9 ("softfloat: fix for C99", 2012-03-17), so let's use that
macro again.

QEMU issues the ioctl(KVM_CAP_PPC_FWNMI) on the first vCPU.
If the first vCPU is currently running, the vCPU mutex is held
and the ioctl() cannot be done and waits until the mutex is released.
This never happens and the VM is stuck.
To avoid this deadlock, issue the ioctl on the same vCPU doing the
RTAS call.
The problem can be reproduced by booting a guest with several vCPUs
(the probability to have the problem is (n - 1) / n, n = # of CPUs),
and then by triggering a kernel crash with "echo c >/proc/sysrq-trigger".
On the reboot, the kernel hangs after:

This is a regression caused by commit d10e05f15d "tpm: Clean up error
reporting in tpm_init_tpmdev()". It's incomplete: be->create(opts)
continues to use error_report(), and we don't set an error when it
fails.
I figure converting the create() methods to Error would make some
sense, but I'm not sure it's worth the effort right now. Revert the
broken commit instead, and add a comment to tpm_init_tpmdev().

The USB_DWC2 switch is currently "default y", so it is included in all
qemu-system-* builds, even if it is not needed. Even worse, it does a
"select USB", so USB devices are now showing up as available on targets
that do not support USB at all. This sysbus device should only be
included by the boards that need it, i.e. by the Raspi machines.

error_propagate_prepend() "behaves like error_prepend()", and
error_prepend() uses "formatting @fmt, ... like printf()".
error_prepend() checks its format string argument, but
error_propagate_prepend() does not. Fix by addint the format
attribute to error_propagate_prepend() and error_vprepend().
This would have caught the bug fixed in the previous commit.
Missed in commit 4b5766488f "error: Fix use of error_prepend() with
&error_fatal, &error_abort".

The function machine_get_loadparm() is supposed to produce a C-string,
that is a NUL-terminated one, but it does not. ElectricFence can detect
this problem if the loadparm machine property is used.
Let us make the returned string a NUL-terminated one.

Right now, -no-reboot prevents secure guests from running. This is
correct from an implementation point of view, as we have modeled the
transition from non-secure to secure as a program directed IPL. From
a user perspective, this is not the behavior of least surprise.
We should implement the IPL into protected mode similar to the
functions that we use for kdump/kexec. In other words, we do not stop
here when -no-reboot is specified on the command line. Like function 0
or function 1, function 10 is not a classic reboot. For example, it
can only be called once. Before calling it a second time, a real
reboot/reset must happen in-between. So function code 10 is more or
less a state transition reset, but not a "standard" reset or reboot.

HF2_GIF_MASK is set in env->hflags2 unconditionally on CPU reset
(see x86_cpu_reset()) but when calling KVM_SET_NESTED_STATE,
KVM_STATE_NESTED_GIF_SET is only valid for nSVM as e.g. nVMX code
looks like
if (kvm_state->hdr.vmx.vmxon_pa == -1ull) {
if (kvm_state->flags & ~KVM_STATE_NESTED_EVMCS)
return -EINVAL;
}
Also, when adjusting the environment after KVM_GET_NESTED_STATE we
need not reset HF2_GIF_MASK on VMX as e.g. x86_cpu_pending_interrupt()
expects it to be set.
Alternatively, we could've made env->hflags2 SVM-only.

The specification says:
0x00 TIME_LOW R: Get current time, then return low-order 32-bits.
0x04 TIME_HIGH R: Return high 32-bits from previous TIME_LOW read.
...
To read the value, the kernel must perform an IO_READ(TIME_LOW),
which returns an unsigned 32-bit value, before an IO_READ(TIME_HIGH),
which returns a signed 32-bit value, corresponding to the higher half
of the full value.
However, we were just returning the current time for both. If the guest
is unlucky enough to read TIME_LOW and TIME_HIGH either side of an
overflow of the lower half, it will see time be in the future, before
jumping backwards on the next read, and Linux currently relies on the
atomicity guaranteed by the spec so is affected by this. Fix this
violation of the spec by caching the correct value for TIME_HIGH
whenever TIME_LOW is read, and returning that value for any TIME_HIGH
read.
