  testing module.

- Fixes for CALL_ON_STACK helper used for stack switching.

- Fix unwinding from bpf code.

- Fix getcpu and remove compat support in vdso code.

- Fix address space control registers initialization.

- Save KASLR offset for early dumps.

- Handle new FILTERED_BY_HYPERVISOR reply code in crypto code.

- Minor perf code cleanup and potential memory leak fix.

- Add couple of error messages for corner cases during PCI device
  creation.
