proper makefile support - setup the makefiles to support "make" and "make install", which builds the kpatch-build tools and installs everything in /usr/local. - update kpatch-build to support new paths - add "kpatch build" wrapper around kpatch-build

include ../Makefile.inc
first pass at a decent user interface This makes it somewhat easy to use. From the root git dir, just: sudo scripts/kpatch-build ~/foo.patch and it'll take care of everything, eventually spitting out the base module (kpatch.ko) and the hotpatch module kpatch-foo.ko. This is still all very crude, but a better user interface is coming soon.

kpatch-build: allow external LDFLAGS When building binaries such as create-diff-object it would be useful to be able to pass LDFLAGS when running make from the command line.

create-kpatch-module: add new program that creates kpatch modules Add new program create-kpatch-module, that, given an intermediate object outputted by create-diff-object, outputs an object (.o) that contains the .kpatch.dynrelas section required by kpatch.

kpatch-elf: introduce a common kpatch-elf and logging interface Introduce a common kpatch elf api by moving all functions and struct declarations related to manipulating kpatch_elf objects from create-diff-object to kpatch-elf.{h,c}. Move logging macros to a separate file log.h, and have kpatch-elf.h include it. These changes will generalize the kpatch-elf and logging api and make it available to other kpatch-build tools.

improve kpatch-build Makefile Right now, the makefile has one target, create-diff-object, which contains all the source/headers as one long list and all the source files compiled in one command to make create-diff-object. This doesn't scale well and doesn't accurately portray the dependencies of each object that contribute to the final binary. This commit renames create-diff-object.c to main.c so that it can be compiled and linked seperately and cleanly in Make and autogenerates dependencies for each .o. This should make it easier to add additional object files, or refactor the very large main.o into seperate object file, later.

restructure building process Right now, we do three build passes: one to build the original tree (full) build, one to build the patch tree (diff build), then one to rebuild original objects that where changed by the patch (diff build). This is going to be a problem when we try to support (near) full tree rebuilds due to changes in commonly included header files. This commit changes the build process to intercept calls to gcc by make using the CROSS_COMPILE environment variable and, during the patched build phase, copies the original object for any object that is about to rebuilt due to a change. This reduces the number of build passes to the minimum possible (two). Signed-off-by: Seth Jennings <sjenning@redhat.com>

make kpatch-build a first class script kpatch-build is outgrowing the kpatch script and probably is a better fit as its own utility instead of being wrapped by kpatch. Install kpatch-build into /usr/local/bin, remove the kpatch wrapper around it, and update the README accordingly.
