Merge tag 'm68knommu-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu
Pull m68knommu updates from Greg Ungerer:
"Only two changes.
One removes the now unused CONFIG_MCPU32 symbol. The other sets a
default for the CONFIG_MEMORY_RESERVE config symbol (this aids
scripting and other automation) so you don't interactively get asked
for a value at configure time.
Summary:
- remove unused CONFIG_MCPU32 symbol
- default CONFIG_MEMORY_RESERVE value (for scripting)"
