# kallsyms support
	# Generate section listing all symbols and add it into vmlinux
	# It's a four step process:
	# 0)  Generate a dummy __kallsyms with empty symbol list.
	# 1)  Link .tmp_vmlinux.kallsyms1 so it has all symbols and sections,
	#     with a dummy __kallsyms.
	#     Running kallsyms on that gives us .tmp_kallsyms1.o with
	#     the right size
	# 2)  Link .tmp_vmlinux.kallsyms2 so it now has a __kallsyms section of
	#     the right size, but due to the added section, some
	#     addresses have shifted.
	#     From here, we generate a correct .tmp_vmlinux.kallsyms2.o
	# 3)  That link may have expanded the kernel image enough that
	#     more linker branch stubs / trampolines had to be added, which
	#     introduces new names, which further expands kallsyms. Do another
	#     pass if that is the case. In theory it's possible this results
	#     in even more stubs, but unlikely.
	#     KALLSYMS_EXTRA_PASS=1 may also used to debug or work around
	#     other bugs.
	# 4)  The correct ${kallsymso} is linked into the final vmlinux.

	# a)  Verify that the System.map from vmlinux matches the map from
