Hello,

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?
