I'm sorry, but ports can get broken for long periods and we don't go ooh it
broke lets revert the change. A few months back the riscpc kernel wouldn't
work because it lacked kvm space, did we back out the core kernel changes
that did that, no, we fixed the riscpc kernel.

Yep it's been a month or more, but I've not seen any complaints about it. As
for why it's not been sorted out yet, I believe it's just that no-one has had
the time to actually look into the issue till now.

I disagree, I don't want to spend half my life reverting changes that have
been made, to only put them back in at a later date.

I would have prefered more time to assess the scope of the build problems so
that we could say right, arm make build doesn't work because of x y and z.
Anyway my currently list of problems is:
gnu/lib/libstc++/config - needs makefile tweaking to install _G_config.h in
/usr/include/arm (I'm not to sure if that's the best place as currently arm26
is built with 2.95.x and arm32 with the intree egcs, so they may differ?)
need dummy (empty) machine/pmap.h to keep dependancies happy
(uvm/uvm_extern.h seems to include it, and then it feels like half the world
includes that ;)
we're missing a few bits from machine/param.h, currently I'm finding those
that are missing and adding them (so far they're the same on arm32 and arm26)
biggest pain with machine/param.h is that everything seems to have a
dependancy on it!
libkvm needs a few real kernel header files, not the dummy ones, eg pcb.h
vmparam.h pmap.h However I expect libkvm to be more closely tied to the
kernel than anything else and may require some sysctl's to make it shared
across arm26 and arm32.
I aim to get a full list together over this weekend so that a proper
assessment of the issues can be made.
PS please note that next week I've no time to deal with this as I'm out
every night doing a bit of acting :)
