Subject: [PATCH 1/3] s390/mm: Drop all pxdp_get()
Date: Wed, 23 Sep 2026 10:02:20 +0530 [thread overview]
Message-ID: <20260923043226.331880-2-anshuman.khandual@arm.com> (raw)
In-Reply-To: <20260923043226.331880-1-anshuman.khandual@arm.com>
Current platform specific pxdp_get() helpers are exact same as the default
ones defined in the generic MM header (include/linux/pgtable.h) thus making
them redundant. Just add required forward declarations.
