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

kmod: Fix install path When building against a different kernel from the one that is currently running, install the kernel module to a directory based on the version of the target kernel rather than the currently running kernel. Signed-off-by: Ross Lagerwall <ross.lagerwall@citrix.com>

always rebuild core module If the kernel updates, make won't detect that the core module needs rebuilding. So always rebuild it.

Makefile: add BUILDMOD parameter to select building kmod core In some cases when packaging it may not be useful to build kmod/core at package build time (for example if using DKMS). Add a parameter 'BUILDMOD' that when set to 'yes' will build kmod/core. Signed-off-by: Chris J Arges <chris.j.arges@canonical.com>

build and install core module with make Build and install the kpatch core module with make and make install, rather than building it every time with kpatch build. The only downside to this approach is that the user has to make and make install kpatch every time they get a new kernel. But this is only temporary, until the kpatch module is delivered in an RPM.

kpatch: change core module path again On RHEL I'm seeing issues with putting the core module in the "extra" path. On the next depmod run, it gets added to modules.dep, and on a subsequent kpatch install I see the following errors: /usr/lib/dracut/modules.d/50drm/module-setup.sh: line 26: /lib/modules/3.10.0-123.4.4.el7.x86_64//weak-updates/kpatch/kpatch.ko: No such file or directory /usr/lib/dracut/modules.d/90kernel-modules/module-setup.sh: line 14: /lib/modules/3.10.0-123.4.4.el7.x86_64//weak-updates/kpatch/kpatch.ko: No such file or directory modinfo: ERROR: Module /lib/modules/3.10.0-123.4.4.el7.x86_64/weak-updates/kpatch/kpatch.ko not found. Until the core module gets merged into Linux, I think we can put it in /usr/lib/kpatch, which is also where the patch modules are going to be delivered in the RHEL RPM. Making sure the other options still work with the kpatch utility for now, so as to keep backwards compatibility between a newer kpatch utility and older core modules. We can break this compatibility for kpatch 0.2.0.
