Subject: Revert "arm64: Mark __stack_chk_guard as __ro_after_init"
From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>
This reverts commit 69e450b170995e8a4e3eb94fb14c822553124870 which is
commit 9fcb2e93f41c07a400885325e7dbdfceba6efaec upstream.
Turns out to break the build when CONFIG_CC_STACKPROTECTOR=y.
