+# 0 - ignore, the value will probably be rotated
+# 1 - warn, a log message will be output
+# 2 - fixup, the kernel will do an expensive aligned read
+# 3 - fixup+warn
+# 4 - signal, the process will get an illegal instruction fault
+# 5 - signal+warn
+# 6 - invalid (has no effect)
+# 7 - invalid (has no effect)

+# Set ALIGN in /etc/default/rcS to override (do not edit this
+# file!) Set ALIGN to empty to avoid changing the kernel
