Kernel 6.4-rc1 ARM boot fails

[Colin Foster]

Hi Ard,

I just wanted to give a heads up. I tested 6.4-rc1 on a Beaglebone Black
and kept getting boot hangs. A bisect led me to commit c76c6c4ecbec ("ARM:
9294/2: vfp: Fix broken softirq handling with instrumentation enabled").

The dying message is "Run /sbin/init as init process"

I'm not sure if this has already been reported. I was able to revert this
patch and confirm things work again.


My current kernel version with the revert is below. I can share my kconfig
if that's needed.

```
# uname -a
Linux buildroot 6.4.0-rc1-00022-g6ceb2f82fe40 #1313 SMP PREEMPT Tue May  9 23:02:58 PDT 2023 armv7l GNU/Linux
```


Thanks, and let me know if you need any more information from me.
