To pick up the changes in:
7f053812da ("random: vDSO: minimize and simplify header includes")
That required adding a copy of include/vdso/unaligned.h and its checking
in tools/perf/check-headers.h.
Addressing this perf tools build warning:
Warning: Kernel ABI header differences:
diff -u tools/include/linux/unaligned.h include/linux/unaligned.h
Please see tools/include/uapi/README for further details.
