Probably a dumb question :).
What prevents the kprobes from being built as a module? We want to use
the kprobes on our systems, but some guys worried about potential
security problems. So it'd be great if we can enable/load kprobes as
needed and then disable/unload after using it. Is it a possible senario?

Kconfig prevents that:

config KPROBES
bool "Kprobes"
depends on MODULES
depends on HAVE_KPROBES

so you can have either CONFIG_KPROBES=y or CONFIG_KPROBES=n, but not =m.
