Please let me know if there are any issue or questions.
Only that this has been the majority of the traffic on the linux-sh
mailing list for over a month and I'm still not sure why anyone
should care.

I have no idea what problem it solves, despite reading a couple dozen
messages in the thread, and the most recent two 0/x intro messages.
Its

purpose seems to be ensuring that lld.llvm.org has more work to do if
it

ever wants to build the kernel without binutils?

I also am not certain why every revision of it is cc'd to linux-sh.
Is
quoted
it generic linker infrastructure change, or is it something that
affects
quoted
this architecture specifically? As far as I can tell nothing in this
most recent 7-patch series touches arch/sh at all, you just cc'd our
list because you think the work you're doing is _important_, not that
it's specifically relevant to us.
Incidentally I'm happy to have been CC'd since this infrastructure is
_really_ nice for doing things generically with device tree. The
ability to add new linker-section-based tables without having to
manually hack up linker script templates will make it so we can do
things like adding tables for cache controllers or mmus (that are
needed quite early in init and can't go through the platform device
system).

BTW we kinda lucked out that there was already the linker table
infrastructure for cpu enable methods for smp; this patch series makes
it so future stuff doesn't have to rely on luck or invasive changes.

Incidentally, I want to use this for the RAID algorithms.
