Subject: [PATCH v4 03/11] s390/lowcore: Remove _AC() from LOWCORE_ALT_ADDRESS
Date: Mon, 21 Sep 2026 17:57:57 +0200 [thread overview]
Message-ID: <20260921155806.2447506-4-hca@linux.ibm.com> (raw)
In-Reply-To: <20260921155806.2447506-1-hca@linux.ibm.com>
Remove the _AC() conversion from LOWCORE_ALT_ADDRESS. This changes the
type of LOWCORE_ALT_ADDRESS from unsigned long to int in C code, however
looking at the current users this should not cause any changes.
This allows to use __stringify(LOWCORE_ALT_ADDRESS) for inline
assemblies, which otherwise wouldn't work because of the UL suffix.
