[PATCH 0/4] Fix DP busy wait and defer disabling overlay plane

[Dan MacDonald]

Thanks Russell!

I think the patch has applied OK - I've just started the build so it
could be a while yet. 12 hours maybe? Its building support for every
arm7 thing under the sun because I'm too lazy (sensible?) to try
hacking it down to size.

Adding the patch to the Arch rc kernel PKGBUILD was as simple as
adding the name of the patch to the source() section, adding a
corresponding 'SKIP' to the end of the md5sums() section and then
adding:

 git apply ../sabre-lite.patch

to the prepare() section of the PKGBUILD. I copied the patch into the
same dir as the PKGBUILD and then ran:

$ makepkg

In the same dir as the kernel PKGBUILD and patches.

Results at last! :D
