And ARM64 will be completely converted to generic > entry in the upcoming patch series. I was trying to implement syscall user dispatch support for ARM64, which is simply about converting arm64 to use the generic entry, and I stumbled upon your patchset on Google. So I decided to write the code for generic syscall entry on top of this patchset, and the code seems to be working. (It boots, and SUD works, but I didn't test ptrace etc.) Should I send the code here?
