Subject: regression: massive trouble with fpu rework
Hi Ingo,
My i7-4790 box is having one hell of a time with this merge window, is
dead in the water. The netconsole log below is v4.1-7254-gc13c81006314,
but trouble begins at bisected point much earlier. If I turn off kvm,
such that I can kinda sorta boot, systemd says many services "enter
failed state", box is pretty much a doorstop. Though I can get to a
prompt, I can't login. If kvm is enabled, it explodes as soon as it
autoloads (wtf does it do that when it's not being used?)
Bisecting to the beginning of my woes takes me to the below. Before
that, it doesn't matter if kvm is enabled or not, all is well. Below
the current gripage with kvm disabled, find the kvm explosion, and
another explosion as I approach the beginning of my box's woes.
067051ccd209623cb56152cf4cb06616ee2bcc5c is the first bad commit
commit 067051ccd209623cb56152cf4cb06616ee2bcc5c

x86/fpu: Do system-wide setup from fpu__detect()
fpu__cpu_init() is called on every CPU, so it is the wrong place
to call fpu__init_system() from. Call it from fpu__detect():
this is early CPU init code, but we already have CPU features detected,
so we can call the system-wide FPU init code from here.
