This contains the previous 28 series in front, with one small fix
mentioned in the last thread, plus one extra patch to remove
unused BRANCH_TO_COMMON macro, so first 29 up to SPR RAW scoreboard
are all quite minimal generated code change.
The next patches start to get a bit more into code change, starting
to mainly attack the "odd" handlers which deviate significantly
from the norm (sreset, machine check, still have pending work to
do on hmi). The aim is to simplify them and make them more regular.
That makes maintaining easier, and also reduces the need to have
a lot of special cases and splits in macros, which helps further
cleanup in future.
After patch 19 I should add it's so much more pleasant to hack on
this code, you don't have to rebuild practically the whole kernel
whenever you change anything.
Oh I also got a KUAP fix in there we should backport.
Thanks,
Nick
