The patch is against drm-next, so git is probably easiest.

# Get Linux git tree (takes a while):
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

cd linux-2.6

# Add the drm-intel-next branch from drm-intel:
git remote add -t drm-intel-next drm-intel-next git://git.kernel.org/pub/scm/linux/kernel/git/anholt/drm-intel.git

# Change working dir to this new stuff:
git checkout drm-intel-next

# Apply patch:
patch --dry-run -p1 < ../fix-i855-cache-coherency-v9.patch

# If that succeeds redo without the --dry-run bit.

Good luck!
