Subject: [RFC PATCH v3 11/12] powerpc: Remove unreachable() from WARN_ON()
Date:   Sat, 25 Jun 2022 00:02:37 +0530
Message-Id: <20220624183238.388144-12-sv@linux.ibm.com>

objtool is throwing *unannotated intra-function call*
warnings with a few instructions that are marked
unreachable. Remove unreachable() from WARN_ON()
to fix these warnings, as the codegen remains same
with and without unreachable() in WARN_ON().
