[RFC PATCH v2 12/15] s390x/cpumodel: Add Sequential-Instruction-Fetching


From: Hendrik Brueckner
Subject: [RFC PATCH v2 12/15] s390x/cpumodel: Add Sequential-Instruction-Fetching facility
Date: Fri, 6 Dec 2024 13:27:48 +0100

The sequential instruction fetching facility provides few guarantees,
for example, to avoid stop machine calls on enabling/disabling kprobes.
