While preparing the system emulation patches, these ones stuck out as

A hang was observed when running a small kernel that exercised VIRTIO

the RCU thread. The hang's cause was determined to be a busy main loop

This commit fixes an indefinite hang when using VIRTIO GPU blob objects
under TCG in certain conditions.

This allows the a plugin which has control of time to supply a callback
so it can control the reported virtual time instead of using the

Rather than allowing cpus_get_virtual_clock() to fall through to
cpu_get_clock() introduce a TCG handler so it can make a decision
about what time it is.
Initially this just calls cpu_get_clock() as before but this will
change in later commits.

No difference in generated code, but the XOR-based formula is
easily understood on its own. This will make more sense once
ADD/SUB stop using dst^src1^src2 to compute AF.

Use the carry-out vector as the basis to compute AF, CF and OF. The cost
is pretty much the same, because the carry-out is just four boolean
operations, and the code is much smaller because add/adc/sub/sbb now
share most of it.
A similar algorithm to what is used in target/i386/emulate can also b
This reduces by ~20% the size of helper_cc_compute_all, and also
