Subject: [RFC] ARM Subarchitecture group maintainership

This is the draft plan for maintaining the ARM subarchitectures in a common
tree, as a way to help coordinate the upstream merging of the
arch/arm/{plat,mach}-* changes into Linus' tree.

This was discussed in great length at the Linaro Developer Summit in Budapest
last week where we worked out an initial plan. We are modeling the maintainance
after how the linux-tip tree is used for the x86 architecture, with a set
of developers that have commit access to one tree on kernel.org and
have mutual trust in one another. Nicolas Pitre and me are funded
by Linaro to do the bulk of the work, while Thomas Gleixner will help
us part-time with his long time architecture maintainance experience.
Despite the funding by Linaro, this is not a Linaro project and all
ARM subarchitectures are welcome to go through our tree.

Russell King's role as ARM maintainer is of course unchanged by this, but
he has the same commit access to the new tree as the other maintainers and
is welcome to work in the same tree. We are also open to nominations for
further people outside of Linaro to join us as committers. Marc Zyngier from
ARM ltd is one of the candidates that has been suggested and I would also
like to see someone from Google. We have to find the right balance with the
number of committers so we get all the work done without stepping on each
other's toes.

Our tree will be strictly organized in topic brances so we can feed them
upstream in the bitesized chunks that Linus likes. The master branch
is an integration branch that pulls all other branches that are scheduled
for the next merge window and itself gets integrated into linux-next.

We will probably not be fully functional during the 2.6.40 merge window,
but we are trying our best to be useful. For 2.6.41, my hope is that
we can merge the bulk of the ARM subarchitecture changes through this
tree. Once Linus is happy with the way that the process works, we can
mandate that all ARM subarchitecture changes go through our tree, until
then it stays voluntary.
