+Subject: [PATCH] pe: Align section size up to page size for mem attrs
+
+Setting memory attributes is generally done at page granularity, and
+this is enforced by checks in `get_mem_attrs` and
+`update_mem_attrs`. But unlike the section address, the section size
+isn't necessarily aligned to 4KiB. Round up the section size to fix
+this.
