Hi,
we started observing boot panics with 5.7 on s390x yesterday:

I only released one of the reports to not spam too much but the panics are
still happening with the most recent code.
These panics are NOT present on the current mainline. All other arches are OK.
Given the call trace, I'm guessing it is something related to
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/commit/?h=linux-5.7.y&id=477d4930b0c7e70c1ac3e3c35e5ad15c5ebde8be
Indeed, looks like we were missing d6df52e9996d ("s390/maccess: add no
DAT mode to kernel_write").
I also took cb2cceaefb4c ("s390: Change s390_kernel_write() return type
to match memcpy()") as a dependency.
Thank you!
