Hi All,
Is there any reason that the m68k arch cannot use the generic
hardirq.h support?
It looks to be the same, unless I am missing something.
If it can then it is simple to merge the non-mmu and mmu
versions of hardirq.h.
Regards

m68k: switch to using asm-generic/hardirq.h
M68k arch can use generic hardirq.h. This also means that we can
simply switch to a single hardirq.h for both m68k and m68knommu.
