Subjectboot failure: stack-protector: Kernel stack is corrupted in: start_secondary
Hi!
With kernels compiled with gcc-10, on two different machines (AMD Phenom2,
AMD 2990WX) I get the following panic during boot:

[ 1.155797] smp: Bringing up secondary CPUs ...
[ 1.159823] x86: Booting SMP configuration:

Not reproducible with gcc-9. Also, it's not a regression as 5.6 and patched
5.5 also fail. Technically, gcc-10 isn't released yet, but with Fedora
having released with gcc-10 as their default compiler, I find it implausible
that no one among big devs uses it yet, thus it's something specific to my
setups.

One of configs attached.


Meow!
