I was making my way through the evil tuning guide and noticed a couple
updates that seem appropriate.  I tried to create an account to be
able to add this into the "discussion" tab but account creation seems

- No need to convert to hex.  According to system(4):

     set [<module>:]<symbol> {=, |, &} [~][-]<value>

         . . .

         Operations that  are  supported  for  modifying  integer
         variables  are: simple assignment, inclusive bitwise OR,
         bitwise AND, one's complement, and  negation.  Variables
         in a specific loadable module can be targeted for modif-
         ication by specifying the variable  name  prefixed  with
         the kernel module name and a colon (:) separator. Values
         can be specified as hexadecimal (0x10), Octal (046),  or
         Decimal (5).
