It's the (ELF) section attributes for the section.  If this
is executable code, it should be "ax"; if it's writable, it
should be "wa"; if it's not initialised, it should be "".

If the section name followed the normal naming conventions,
(newer) GCC could figure out the section attributes itself;
but then, ".text.kprobes" would imply executable, maybe the
section is really misnamed?  Or maybe you need the "ax"
flags :-)
