While the kernel itself doesn't use DWARF unwinding, user code expects to be able to unwind the vDSO. The vsyscall (AT_SYSINFO) entry is manually CFI-annotated, and this tests that it unwinds correctly. I tested the test by incorrectly annotating __kernel_vsyscall, and the test indeed fails if I do that.
