lib: Add shared copies of some GCC library routines Many ports (m32r, microblaze, mips, parisc, score, and sparc) use functionally identical copies of various GCC library routine files, which came up as we were submitting the RISC-V port (which also uses some of these). This patch adds a new copy of these library routine files, which are functionally identical to the various other copies. These are availiable via Kconfig as CONFIG_GENERIC_$ROUTINE, which currently isn't used anywhere.

move libgcc.h to include/linux Introducing a new include/lib directory just for this file totally messes up tab completion for include/linux, which is highly annoying. Move it to include/linux where we have headers for all kinds of other lib/ code as well. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>

Add notrace to lib/ucmpdi2.c As part of the MIPS conversion to use the generic GCC library routines, Matt Redfearn discovered that I'd missed a notrace on __ucmpdi2(). This patch rectifies the problem.
