Hi Richard and Linas,
It's good to finally see the source for this, and I have a good feeling
about the quality of the code, so it should not be a problem to resolve
the remaining issues in time to get it into the next merge window.
I have gone over all patches once now and commented about everything
that looked odd or wrong. Most of the issues are really just small
changes. Removing support for the legacy syscalls is an easy change
in the kernel but it might require significant changes in the libc
implementation. It's not a big problem if your libc still requires the
old interfaces at the time the architecture gets merged upstream,
that will just mean that you have to have a small kernel patch to add
them back in while transitioning to the new libc.
As I commented on patch 33, I think the platform specific patches should
not get merged before everything is converted to device tree based
probing. This should also not keep the rest from going in. I think it
would be good to do the conversion together with the ARM-MSM platform
that seems to share a lot of the device specific code, and it would
be bad to end up with duplicate work here or (worse) with incompatible
DT bindings.
