lib/math: Add a `do_div' test module
Implement a module for correctness and performance evaluation for the `do_div' function, often handled in an optimised manner by platform code. Use a somewhat randomly generated set of inputs that is supposed to be representative, using the same set of divisors twice, expressed as a constant and as a variable each, so as to verify the implementation for both cases should they be handled by different code execution paths. Reference results were produced with GNU bc.
At the conclusion output the total execution time elapsed.

ccflags-remove-$(CONFIG_FUNCTION_TRACER) += $(CC_FLAGS_FTRACE)
exists here in sub-directories of lib/ to keep the behavior of commit 2464a609ded0 ("ftrace: do not trace library functions").
Since that commit, not only the objects in lib/ but also the ones in the sub-directories are excluded from ftrace (although the commit description did not explicitly mention this).
However, most of library functions in sub-directories are not so hot. Re-add them to ftrace.
Going forward, only the objects right under lib/ will be excluded.

kbuild: introduce ccflags-remove-y and asflags-remove-y
CFLAGS_REMOVE_<file>.o filters out flags when compiling a particular object, but there is no convenient way to do that for every object in a directory.
Add ccflags-remove-y and asflags-remove-y to make it easily.
Use ccflags-remove-y to clean up some Makefiles.
The add/remove order works as follows:
[1] KBUILD_CFLAGS specifies compiler flags used globally
[2] ccflags-y adds compiler flags for all objects in the current Makefile
[3] ccflags-remove-y removes compiler flags for all objects in the current Makefile (New feature)
[4] CFLAGS_<file> adds compiler flags per file.
[5] CFLAGS_REMOVE_<file> removes compiler flags per file.
Having [3] before [4] allows us to remove flags from most (but not all) objects in the current Makefile.
For example, kernel/trace/Makefile removes $(CC_FLAGS_FTRACE) from all objects in the directory, then adds it back to trace_selftest_dynamic.o and CFLAGS_trace_kprobe_selftest.o
The same applies to lib/livepatch/Makefile.
Please note ccflags-remove-y has no effect to the sub-directories. In contrast, the previous notation got rid of compiler flags also from all the sub-directories.
The following are not affected because they have no sub-directories:
arch/arm/boot/compressed/ arch/powerpc/xmon/ arch/sh/ kernel/trace/
However, lib/ has several sub-directories.
To keep the behavior, I added ccflags-remove-y to all Makefiles in subdirectories of lib/, except the following:
lib/vdso/Makefile - Kbuild does not descend into this Makefile lib/raid/test/Makefile - This is not used for the kernel build
I think commit 2464a609ded0 ("ftrace: do not trace library functions") excluded too much. In the next commit, I will remove ccflags-remove-y from the sub-directories of lib/.
