It seems like CONFIG_DEBUG_MACRO_DEFINITIONS can blow up the size of the
kernel image significantly. Perhaps it should be marked with a

    depends on !COMPILE_TEST

to avoid having all{mod,yes}config and randconfigs trip over it?

Cheers,
Nathan

Hi Nathan,

One of the issues this patch was supposed to address was to overcome
the behavior of the debug-split in new GCC/Clang compilers.

As was agreed with Nick
https://lore.kernel.org/all/CAKwvOdmq-6poADRajPi6CXuKsYYEPEe1tjXFuLEH6kHprerUdw@mail.gmail.com/
it was better to fix it up by simply assigning DEBUG_CFLAGS := -g at
the beginning of Makefile.debug without adding an additional
CONFIG_DEBUG_MACRO_DEFINITIONS Kconfig option.

Regards,
Dmitrii
