Subject: [PATCH v2 00/35] exception cleanup, syscall in C and !COMPAT
Date:   Tue, 26 Nov 2019 21:13:14 +0100

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.

Refreshed the patchset to fix build error on ppc32 and ppc64e.

Thanks

Michal
