The series is already upstream. You just need to add an arm version of that linked patch. But up to you.Your series modified the existing x86 custom arch_get_unmapped_area*() functions, arm64 uses the generic implementation of those so I'd have to either add custom implementations (which I can't imagine would be met with great enthusiasm) or update the generic ones. A generic implementation seems reasonable and it looks like RISC-V would also end up using it so while it's a bit invasive it does seem more sensible to do the change there.
Ah, I misunderstood. Makes sense.
