linux/runtime.h: more CONFIG_USER_NS fallout
Partially unrolling commit 7d35a948401, because on modern kernels
(3.14+), the from_k?id_munged functions are defined as inlines, and
should be used regardless of CONFIG_USER_NS etc. The buildrun.cxx
exportedness test for from_kuid_munged would fail, triggering our
runtime to use a do-nothing macro instead.
Until a more programmatic way is found for those unidentified older
kernels that have CONFIG_USER_NS but no from_k?id_munged inlines,
for now a user will have to work around the build problem with
% stap -DSTAP_FAKE_KID_MUNGED
===================
I'm working on a fix.
