If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit be1439091957c02a3406df8d18ff2aae59d6d298 Author: Benjamin Gray <bgray@xxxxxxxxxxxxx> Date: Wed Apr 17 21:23:17 2024 +1000 selftests/powerpc/dexcr: Add -no-pie to hashchk tests [ Upstream commit d7228a58d9438d6f219dc7f33eab0d1980b3bd2f ] The hashchk tests want to verify that the hash key is changed over exec. It does so by calculating hashes at the same address across an exec. This is made simpler by disabling PIE functionality, so we can re-execute ourselves and be using the same addresses in the child. While -fno-pie is already added, -no-pie is also required.
