gcc-plugin: create a ppc64le GCC plugin which inserts nops after local calls
This is in response to an upstream discussion for the following patch: https://lkml.kernel.org/r/1508217523-18885-1-git-send-email-kamalesh@linux.vnet.ibm.com This should hopefully make it a lot easier for the ppc64le kernel module code to support klp relocations. The gcc-common.h and gcc-generate-rtl-pass.h header files are copied from the upstream Linux source tree. Signed-off-by: Josh Poimboeuf <jpoimboe@redhat.com>
