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 2014-02-13 16:04:35 +00:00			`# make rules`
fix KPATCH_BUILD path use the build symlink in /lib/modules for a more portable path to the build env for the kernel. Signed-off-by: Seth Jennings <sjenning@redhat.com> 2014-03-05 17:31:15 +00:00			`KPATCH_BUILD ?= /lib/modules/$(shell uname -r)/build`
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. 2014-02-18 04:37:07 +00:00			`THISDIR := $(abspath $(dir $(lastword $(MAKEFILE_LIST))))`

kmod/core: remove assembler code Long ago, the kpatch_trampoline required being written in assembler, but that's no longer needed now that it integrates nicely with ftrace. Move it to a C function and rename it kpatch_ftrace_handler. 2014-03-13 18:02:28 +00:00			`kpatch.ko: core.c`
