From 331771e836e6a32c8632d8cf5e2cdd94471258ad Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Fri, 16 Sep 2022 14:40:57 +1000 Subject: [PATCH] powerpc/vmlinux.lds: Ensure STRICT_ALIGN_SIZE is at least page aligned Add a check that STRICT_ALIGN_SIZE is aligned to at least PAGE_SIZE. That then makes the alignment to PAGE_SIZE immediately after the alignment to STRICT_ALIGN_SIZE redundant, so remove it.
