klp-build fails when a later patch in the series depends on an earlier
one, because it fixes each patch against the original source on its
own. Patch 1 fixes this by combining the patches into a single patch
before adding the #line directives.
So far, testing this step has needed a full kernel build. Patch 2 adds
a --patch-only option, which validates and fixes the patches, prints
the result, and exits without building.
Patches 3-11 use it to add a kselftest target, livepatch/test_klp_build.
Each test builds a small source tree, runs "klp-build --patch-only" on
some patches, and checks the patch it prints. The tests compile
nothing, need no root, and take about a second. To run them:
make -C tools/testing/selftests/livepatch/test_klp_build tests
