+Subject: [PATCH] core, ldelf: link: add -z execstack
+
+When building for arm32 with GNU binutils 2.39, the linker outputs
+warnings when generating some TEE core binaries (all_obj.o, init.o,
+unpaged.o and tee.elf) as well as ldelf.elf:
+
+ arm-poky-linux-gnueabi-ld.bfd: warning: atomic_a32.o: missing .note.GNU-stack section implies executable stack
+ arm-poky-linux-gnueabi-ld.bfd: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
+
+The permissions used when mapping the TEE core stacks do not depend on
+any metadata found in the ELF file. Similarly when the TEE core loads
+ldelf it already creates a non-executable stack regardless of ELF
+information. Therefore we can safely ignore the warnings. This is done
+by adding the '-z execstack' option.
