I'm assuming your CPU cannot do 64-bit mode?
Can you send .config, /proc/cpuinfo and full dmesg pls?
Privately is fine too.
Thx.

Ok, thanks for the info.
On your next reply, can you please hit the "reply-to-all" button so that
I can get your reply and not have to go fish it out of the lkml flood? I
would've easily missed it if tglx didn't point me to it.
In any case, your CPU is too old for me to even find such a box and your
.config boots fine in qemu so I guess we'll have to debug it.
Can you apply the diff below on your 5.14.9 kernel, boot with it and
send full dmesg again?
Thx.

I can confirm that with the patch installed, the system does indeed boot normally with nothing out of the ordinary in the dmesg log. Thanks.

On a 64 bit kernel even 32bit user space which supplies broken mxcsr
values has to be considered malicious.
The 32bit story on those stone age machines is different because the
hardware is simply buggy and we can't differentiate between broken
hardware and broken or malicious software.
Thanks,

so restore the original behavior only for 32-bit kernels where you have
ancient machines with buggy hardware. For 32-bit programs on 64-bit
kernels, user space which supplies wrong MXCSR values is considered
malicious so fail the sigframe restoration there.
