[PATCH 0/2] Stackleak for arm64
Hi, This is the new version of stackleak for arm64 to go with v14 of the series for x86. I have a cover letter and few more cc's to go along with some of the prep work. I also apologize for terrible versioning on these series. Usually I try to just reply to the top level patch with this addition and not actually put a version on it. I negelcted to do that last time but as mentioned this is inteded to go with v14.

[PATCH 0/2] Stackleak for arm64
This is an extension of the arm64 stackleak plugin, based on top of the v11 version for x86. The biggest change from the previous version is the conversion from assembly to C. It's mostly taken straight from the x86 version modulo a few cleanups and seems to work just fine. If this gets Acks, I'd like Kees to start carrying in his tree for -next.

This passed both of the LKDTM tests. Hello, Laura, Thank you. I'll take some time to learn your patches and test them on my LeMaker HiKey board. I'll return with the feedback. Best regards, Alexander

This is the arm64 version of the STACKLEAK plugin originall from grsecurity. See https://marc.info/?l=kernel-hardening=151880470609808 for the full x86 version. This is based on top of Kees' branch for stackleak and has been cleaned up to use a few macros from that branch. Comments welcome, if there are no major objections Kees will queue this up to get some CI testing. This passed both of the LKDTM tests.
