From: Ard Biesheuvel <a...@kernel.org>
The .head.text section carries the startup code that runs with the MMU
off or with a translation of memory that deviates from the ordinary one.
So avoid instrumentation with the stackleak plugin, which already avoids
.init.text and .noinstr.text entirely.
Fixes: 48204aba801f1b51 ("x86/sme: Move early SME kernel encryption handling
into .head.text")
