- Get rid of expensive stck (store clock) usages where possible.
Utilize cpu alternatives to patch stckf when supported.
- Make tod_clock usage less error prone by converting it to a union and
rework code which is using it.
- Machine check handler fixes and cleanups.
- Drop couple of minor inline asm optimizations to fix clang build.
- Default configs changes notably to make libvirt happy.
- Various changes to rework and improve qdio code.
- Other small various fixes and improvements all over the code.
