You just have to convince James @)

That would mean dropping support for prev-gen es7000 which are not that
old actually (only a few years). But I think with a little effort the
old es7000 code could be fit into the generic architecture. It is not
that far away from a normal PC.

mach-numaq (not in arch, but spread out all over the port)
I hear there are only a one or two machines running left.
Unfortunately they are in test.kernel.org, but hopefully
they will die soon.
NUMAQ has quite a lot of ugly ifdefs and special cases that would be
great to eliminate

mach-bigsmp/mach-summit (also in asm only)
obsolete, should be deprecated for mach-generic
(just generic currently pulls in code from them)
A good first step would be to just disable the separate CONFIG
options and only allow using them through generic.
