arm64: Add support for PR_SPEC_DISABLE_NOEXEC prctl() option The PR_SPEC_DISABLE_NOEXEC option to the PR_SPEC_STORE_BYPASS prctl() allows the SSB mitigation to be enabled only until the next execve(), at which point the state will revert back to PR_SPEC_ENABLE and the mitigation will be disabled. Add support for PR_SPEC_DISABLE_NOEXEC on arm64. Reported-by: Anthony Steinhauser <asteinhauser@google.com> Signed-off-by: Will Deacon <will@kernel.org>
