Like so?:
diff --git a/scripts/checkstack.pl b/scripts/checkstack.pl
index 122aef5e4e14..8502de57e2ef 100755
--- a/scripts/checkstack.pl
+++ b/scripts/checkstack.pl
@@ -41,6 +41,8 @@ my (@stack, $re, $dre, $x, $xs, $funcre);

$arch = `uname -m`;
chomp($arch);
+ } elsif ($arch eq 'arm64') {

}
$x = "[0-9a-f]"; # hex character
Thanks!
