Subject: [PATCH v7 04/29] s390: Move sske_frame() to a header
Date: Wed, 4 Feb 2026 16:02:33 +0100 [thread overview]
Message-ID: <20260204150259.60425-5-imbrenda@linux.ibm.com> (raw)
In-Reply-To: <20260204150259.60425-1-imbrenda@linux.ibm.com>
Move the sske_frame() function to asm/pgtable.h, so it can be used in
other modules too.
Opportunistically convert the .insn opcode specification to the
appropriate mnemonic.
