CONSOLE_LOGLEVEL_DEFAULT is nothing more than a shorthand of

When you change CONFIG_CONSOLE_LOGLEVEL_DEFAULT from Kconfig, almost
all objects are rebuilt because CONFIG_CONSOLE_LOGLEVEL_DEFAULT is
used in <linux/printk.h>, which is included from most of source files.
In fact, there are only 4 users of CONSOLE_LOGLEVEL_DEFAULT:
arch/x86/platform/uv/uv_nmi.c
drivers/firmware/efi/libstub/efi-stub-helper.c
drivers/tty/sysrq.c
kernel/printk/printk.c
So, when you change CONFIG_CONSOLE_LOGLEVEL_DEFAULT and rebuild the
kernel, it is enough to recompile those 4 files.
Do you change CONFIG_CONSOLE_LOGLEVEL_DEFAULT so often that it becomes a
problem?
