>Description:
While discussing the fix on DEBUG build option for one of the kernel configs (https://github.com/NetBSD/src/commit/c1fbfb0504515c3716072ef8f01b77f9769f84d4),
Matthew proposed to file a PR to remove of all STATIC/INLINE macros in the codebase.

Currently they are defined and used in the files below (unless I missed something):
sys/dev/cardbus/cardbus.c, cardbus_map.c, cardslot.c, rbus.c
sys/dev/ic/wi.c
sys/dev/isa/gus.c
sys/dev/iscsi/iscsi_globals.h, iscsi_main.c, iscsi_rcv.c, iscsi_send.c, iscsi_text.c, iscsi_utils.c
sys/dev/kloader.c
sys/dev/marvell/gtmpsc.c, if_gfe.c, if_mvxpe.c, mvxpbm.c, mvxpsec.c
sys/dev/pci/pccbb.c
sys/dev/pcmcia/if_xi.c
sys/dev/spi/spiflash.c

As I understand the reasoning, while it still can be sometimes useful for debugging (as the intention was), incorrect static usage can be more "damaging".
>How-To-Repeat:
N/A
>Fix:
Replace STATIC/INLINE macro with static/inline keywords in files above and cleanup macro definition code.
