for execvesh and portshellsh append "/bin/sh\x42" to the code.

if you want to execute something different than "/bin/sh", be sure to properly
set the first four bytes to a valid opcode ("/bin" is valid) or insert a nop
and adjust the self-relocation.

the codedump utility build extra cache control syscalls, so it flushes all
caches properly and you can run the code safily then from a flushed cache.

example:

scut@hyperion $ make >/dev/null
scut@hyperion $ ./execvesh
  <... dumps the hexcode ...>
scut@hyperion $ ./execvesh exec
len = 68
$
$ exit
scut@hyperion $
