I agree a summary description that explains how to use these relocations with an example would be great. Key things that would be useful to point out: - The checking...

Using prel on an absolute address is weird and non-intuitive. It would be more reasonable to do it like: ``` adrp x0, :pg_hi21_nc: global movk x0, :abs_g3: global add x0,...

Yes both relocation examples behave identically. You're right, the abs_g3 relocation is not allowed in shared objects, so using prel_g3 is the only option there. If we change prel_g3, it...

How could the registers after a context switch be in unprotected memory unless the OS is completely broken by design? If an attacker can read/write the stored registers of all...

Can we progress this? It seems there is agreement on most of these, so just keep FEAT_BTI.
