As both personally, and the policy of my employer we try and ensure we
can offer our customers at-least the previous 'stable' kernel release
and ensure that our development process tracks the kernel -rcX
candidates. We also run an autobuilder[1] which runs all -git releases
through an automated build (no auto-test yet) to ensure that we can
detect any build or configuration errors in the releases. 

ARM is a fast moving area due to the amount of sillicon vendors out
there who seem intent on doing their own thing, and often forking
hardware blocks they use during differing development branches. I
am currently looking at merging support for the S3C6400 (new) and
finishing S3C2443 (similar to 6400) and the S3C24A0... this means
that I have a lot of code to look through before each release and
having a stall will just keep the backlog building, making my job
a lot more difficult.
