tools: separate out shared radix-tree components The core components contained within the radix-tree tests which provide shims for kernel headers and access to the maple tree are useful for testing other things, so separate them out and make the radix tree tests dependent on the shared components. This lays the groundwork for us to add VMA tests of the newly introduced vma.c file.

This requires $(SRCARCH), which is provided by Makefile.arch, so include that.. There still aren't that many headers so also just smush all of them into SHARED_DEPS instead of starting to do any header dependency hocus pocus.

tools: fix shared radix-tree build The shared radix-tree build is not correctly recompiling when lib/maple_tree.c and lib/test_maple_tree.c are modified - fix this by adding these core components to the SHARED_DEPS list. Additionally, add missing header guards to shared header files.

tools: testing: fix phys_addr_t size on 64-bit systems The phys_addr_t size is predicated on whether CONFIG_PHYS_ADDR_T_64BIT is set or not. In the VMA tests, virt_to_phys() from tools/include/linux casts a volatile void * pointer to phys_addr_t, if CONFIG_PHYS_ADDR_T_64BIT is not set, this will be 32-bit and trigger a warning. Obviously this might also lead to truncation, which we would rather avoid. Fix this by adjusting the generation of generated/bit-length.h to generate a CONFIG_PHYS_ADDR_T{bits}BIT define. This does result in the generation of the useless CONFIG_PHYS_ADDR_T_32BIT define for 32-bit systems, but this should have no effect, and makes implementation of this easier. This resolves the issue and the warning.
