Subject: [PATCH v3 03/23] s390: Move sske_frame() to a header
Date: Thu, 6 Nov 2025 17:10:57 +0100 [thread overview]
Message-ID: <20251106161117.350395-4-imbrenda@linux.ibm.com> (raw)
In-Reply-To: <20251106161117.350395-1-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.
