096384c921 x86/apic: same calibration for single and multi kernel
Sample CPU timestamp counter for APIC calibration in both cases. This
has proven to be more reliable than waiting for and counting timer
interrupts.

8054c36f26 gdb-scripts: backtrace and context switching for tasks
These new commands allow to show backtraces of any HermitCore task as
well as completely switching the current context. This way, you can
inspect each task as if it were running, which hasn't been possible
until now, because neither GDB nor Qemu have knowledge about the task
structure of HermitCore.
