Subject: [PATCH 00/33] exception cleanup, syscall in C and !COMPAT

Hello,

This is merge of https://patchwork.ozlabs.org/cover/1162376/ (except two
last experimental patches) and
https://patchwork.ozlabs.org/patch/1162079/ rebased on top of master.

There was minor conflict in Makefile in the latter series.

Thanks

Michal
