v5.15+ backport request

please backport

e7d24c0aa8e678f41 gcc-plugins/stackleak: Avoid .head.text section

to stable kernels v5.15 and newer. This addresses the regression reported here:

https://lkml.kernel.org/r/dc118105-b97c-4e51-9a42-a918fa875967%40hardfalcon....

On v5.15, there is a dependency that needs to be backported first:

ae978009fc013e3166c9f523f8b17e41a3c0286e gcc-plugins/stackleak: Ignore .noinstr.text and .entry.text

The particular issue that this patch fixes does not exist [yet] in v6.1 and v5.15, but I am working on backports that would introduce it. But even without those backports, this change is important as it prevents input sections from being instrumented by stackleak that may not tolerate this for other reasons too.

Thanks, Ard.
