Bug Description

Testcase proc01 from ubuntu_ltp.fs fails on Hirsute s390x systems with:

12:48:34 DEBUG| [stdout] proc01 1 TFAIL : proc01.c:400: read failed: /proc/sys/kernel/spl/hostid: errno=EFAULT(14): Bad address

I was also able to reproduce this on a amd64 VM running 5.11.0-31-generic by loading the spl module and running:

$ sudo cat /proc/sys/kernel/spl/hostid
cat: /proc/sys/kernel/spl/hostid: Bad address

This is probably not a regression, affecting only s390x now likely because the spl module wasn't loaded on the previous runs. s390x systems are not re-deployed for the regression tests, so this could be a lingering module loaded for previous tests.
