Hi Ingo,

On your request I'm resending the report here, with attached dmesg,
kconfig and reproduce script.

I'll go on to test your split up commits, too.

https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.x86/fpu

It looks 6fc19a42 ("x86/fpu: Use validate_xstate_header() to validate
the xstate_header in sanitize_restored_xstate()") is the first bad commit.

Attached are the dmesg files for 6fc19a42 and its parent commit.

The panic message is,
