LINUX KERNEL --
On top of many other changes with Linux 3.18 is also a common mailbox driver/framework for the kernel.

Going back many months months has been the effort to provide a generic mailbox framework for the Linux kernel. Jassi Brar who has been developing this code described it as a "common framework for client/protocol drivers and
controller drivers of Inter-Processor-Communication (IPC)."

In the 3.18 mailbox pull request Jassi Brar explains, "A framework for Mailbox controllers and clients have been cooking for more than a year now. Everybody in the CC list had been copied on patchset revisions and most of them have made sounds of approval, though just one concrete Reviewed-by. The patchset has also been in linux-next for a couple of weeks now and no conflict has been reported. The framework has the backing of at least 5 platforms, though I can't say if/when they upstream their drivers (some businesses have 'changed')."

As I'm not too familiar yet with this new code, for those wishing to learn more about this Linux kernel mailbox framework, read the kernel documentation for additional details.
