The current API allows us to report a single status, which we've defined as:
Frozen: has a successor, treated as qmp_locked, may or may not be enabled.
Locked: no successor, qmp_locked. may or may not be enabled.
Disabled: Not frozen or locked, disabled.
Active: Not frozen, locked, or disabled.
"Frozen" was a good description a long time ago, but it isn't adequate now.
Rename the frozen predicate to has_successor to make the semantics of the
predicate more clear to outside callers.
In the process, remove some calls to frozen() that no longer semantically
make sense. For enabled and

These mean the same thing now. Unify them and rename the merged call

Currently, enabled means something like "the status of the bitmap

bitmap is recording guest writes, and is allowed to do so."
In many places, this is how this predicate was already used.
We'll allow users to call user_locked if

Guests started with NVDIMMs larger than the underlying host file produce
confusing errors inside the guest. This happens because the guest

Changes since v2:
* Fix botched subject line, include r-b tags.
Changes since v1:
* Move more of hw/s390x/tod.h to a new header.
* Use time2tod.

Richard Henderson (2):
target/s390x: Split out s390-tod.h
target/s390x: Implement STCK et al for CONFIG_USER_ONLY
This is a non-privileged instruction that was only implemented
for system mode. However, the stck instruction is used by glibc,
so this was causing SIGILL for programs run under debian stretch.

As far as I can see currently IOThread offloading is used only for

I expect that network devices can also benefit from processing in
separate thread but I couldn't find any recent work in this

HP-UX 10.20 uses busmaster writes to the CPU EIR to signal
interrupts from the SCSI constroller. (Similar to what is known
as MSI on x86)

When QEMU is compiled with -O0, these functions are inlined
which will cause a wrong restart address generated for the TB.
