This applies on top of the previous exception series. Until now the focus was on making the code generation macros sane, ironing out irregularities and needless differences in handlers, and sharing code. Some change of generated code was required, but minimised as much as possible.
This series begins to change generated code in a bigger way. This is an assortment of changes, one of the big goals goals is really moving code and especially branches and logic and conditional compilation out of "unrelocated" interrupt entry points, with the hope of making KASLR more effective when it is implemented. After this is a more significant rework of the instruction sequences with the aim of improving performance, but I will stop here for the next merge window.
