If you anticipate running this kernel on a computer with a MC68020
processor, say Y. Otherwise, say N. Note that the 68020 requires a
Upon second thought, this won't work for multi-CPU kernels, as there's
no runtime
check. The logic needs to be reverted, like:
config CPU_HAS_NO_BITFIELDS
bool
config M680000
bool "68000 support"
select CPU_HAS_NO_BITFIELDS
so a kernel built to run on both 68000 and 68020 will not use the
bitfield instructions.
Sorry I didn't realize that earlier.
