Oh, my bad.  "git clone" grabs the entire kernel history, so it has a
high (one-time) cost.

You can find instructions for testing a patch while using the usual
Debian source package here:

 http://kernel-handbook.alioth.debian.org/ch-common-tasks.html

The short version is that after extracting the kernel source by
whatever means is convenient to the current directory, one can run

	cp /boot/config-$(uname -r) .config; # current configuration
	make localmodconfig; # optional: minimal configuration
	make deb-pkg; # optionally with -j<num> for parallel build

to get a .deb for the unpatched kernel, and then

	patch -p1 <patch1
	patch -p1 <patch2
	make deb-pkg; # maybe with -j4

to get a .deb for the patched kernel.

The "ketchup" tool, which can download patches instead of full
tarballs from kernel.org to make downloads of successive kernel
releases a little smaller, might be helpful.

Sorry, no --- I do my development work on a laptop that is not able to
compile the kernel very quickly.

Hope that helps,
