Subject: [PATCH] SELinux: inline selinux_is_enabled in !CONFIG_SECURITY_SELINUX

Without this patch building a kernel emits millions of warning like:

include/linux/selinux.h:92: warning: ‘selinux_is_enabled’ defined but not used

When it is build without CONFIG_SECURITY_SELINUX. This is harmless, but
the function should be inlined, so it gets compiled out.

Linus, I'll assume you'll want to apply this directly.

What I want is to just get pull requests that were well tested in the
first place. When I see an error in a pull request, my reaction is to just
reset awat from it, and not wanting to have anything what-so-ever to do
with the git tree I pulled from.

Give me a few days to get over the disgust.

Sorry about this mess.

These fixes fix build problems, so here's the latest (also, I'll be
on a long haul flight in a few days). Boot tested with and without
SELinux enabled.
