samples/hid: add new hid BPF example Everything should be available in the selftest part of the tree, but providing an example without uhid and hidraw will be more easy to follow for users. This example will probably ever only work on the Etekcity Scroll 6E because we need to adapt the various raw values to the actual device. On that device, the X and Y axis will be swapped and inverted, and on any other device, chances are high that the device will not work until Ctrl-C is hit. The Makefiles are taken from samples/bpf to not reinvent the wheel and to force using in-kernel libbpf and bpftool.

kbuild: use $(src) instead of $(srctree)/$(src) for source directory Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for checked-in source files. It is merely a convention without any functional difference. In fact, $(obj) and $(src) are exactly the same, as defined in scripts/Makefile.build: src := $(obj) When the kernel is built in a separate output directory, $(src) does not accurately reflect the source directory location. While Kbuild resolves this discrepancy by specifying VPATH=$(srctree) to search for source files, it does not cover all cases. For example, when adding a header search path for local headers, -I$(srctree)/$(src) is typically passed to the compiler. This introduces inconsistency between upstream and downstream Makefiles because $(src) is used instead of $(srctree)/$(src) for the latter. To address this inconsistency, this commit changes the semantics of $(src) so that it always points to the directory in the source tree. Going forward, the variables used in Makefiles will have the following meanings: $(obj) - directory in the object tree $(src) - directory in the source tree (changed by this commit) $(objtree) - the top of the kernel object tree $(srctree) - the top of the kernel source tree Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced with $(src).

bpf: Replace deprecated -target with --target= for Clang The -target option has been deprecated since clang 3.4 in 2013. Therefore, use the preferred --target=bpf form instead.
