The spl() functions block interrupts of equal or lesser priority, not of

higher priority. This man page could use some more improvement, but this
paragraph was too misleading to be ignored.

 .Fn splx "int s"
 .Sh DESCRIPTION
 These functions raise and lower the system priority level.
-They are used by kernel code running at any given priority level to
-block higher-priority interrupts, so that it can safely access
-variables or data structures which are used by kernel code that runs
-at a higher priority level.
+They are used by kernel code to block interrupts with priority less
+than or equal to the named level (i.e.,
+.Fn spltty
+blocks interrupts of priority less than or equal to
+.Dv IPL_TTY ) .
+The code may then safely access variables and data structures which
+are used by kernel code that runs at an equal or lower priority level.
