Subject: [RFC 00/30] compat: deal with kernel backport namespace

From: "Luis R. Rodriguez" <mcgrof@...not-panic.com>

This patch series deals with the project that aims at
backporting the Linux kernel [0]. If you don't care
for that, at least read this and patch #1, the rest
you can nuke.

Ben reports compat_ namespace is already taken by the
kernel, and while this is slightly true, I rather just
deal with this now and avoid any future issues.

I've chosen backport_. Any nay's?

I've broken this set for easier review to one per kernel
backported. Each patch is test compiled with ckmake [1]
for kernels 2.6.24 - 3.9. I've then test compiled all this
against compat-drivers-2013-03-15, which sucks in Ethernet,
802.11 Bluetooth, and DRM video drivers against linux-next
tag next-20130315 and it all went fine for all kernels
2.6.24 - 3.9.

I suppose the next set here, if we really are adamant about
any possible namespace issues (is it necessary?) is to use
include/linux/backport/ instead of include/linux/compat/ and
likewise rename the compat module to backports as with
COMPAT_* macros.

I'm sending these as RFCs in hopes to get reviews / testing
prior to any radical change, but more importantly in hopes
anyone who cares for maintaining a Linux distribution will
review.
