[WireGuard] Error building against grsec-enabled kernel

[Jason A. Donenfeld]

Hey Toke,

Good to see you in this neck of the woods!

Yes -- the __read_mostly annotation needs to go away for grsec. I had
this building and running a few months ago on there. I'll revive that
work. I'm at a conference right now (codeblue.jp) giving a talk on
WireGuard, but I'll dig up my grsec build system ASAP and get back to
you. In the mean time, if you can muster a backtrace, this of course
would be excellent.

Talk soon,
Jason
