[PATCH v2 1/2] examples: systemtap: Warn users to properly update 'amd-sev-es-vmsa.stp'

[Peter Krempa]

The script references a very specific line in the kernel source code and
a very specific struct. Further changes to the kernel are likely going
to break it. Set the expectations by adding a warning to the reader.

 # A script that captures the VMSA blob for the boot vCPU and
 # first additional vCPU, when a KVM guest is booted with SEV-ES
 #
+# NOTE: This directly references specific structures and places in the
+#       kernel source code. It is expected that this example will need to be
+#       editted to match the kernel you intend to run it against.
+#
 # The captured VMSA will be printed to the console in hex format,
 # and can be converted to the required binary format by feeding
 # it through
