I just had a closer look. Your patch order makes sense. It's less
noise that way due to the previous removal of the 3 users of the macro. 

I applied the series with the following changes:

- Moved 3/3 before 2/3 to make it clear that this is a consecutive cleanup
- Simplified 3/3 (patch below)
- fixed the commit log of 3/3 so it points out why the cleanup is done 

Btw, can you please add a "x86:" prefix to your subject lines ?

Thanks,

The early exception handlers are currently set up using a macro
recursion. There is only one user left. Replace the macro with a
standard loop in place.
