Nothing includes these headers. And a few tests found no hits for the things they provide (which makes sense). MC68332.h, mac_mouse.h, and mcfmbus.h are all unused since at least v2.6.12-rc2 (I didn't bother looking further back than that). apollodma.h is unused since v2.6.19: commit 2ed0ce5b57950a620155433c62a5a02a067f1376 ("m68k/Apollo: Remove obsolete arch/m68k/apollo/dma.c") removed the last file interested in that header. And everything interested in was removed in the v2.6.28 release cycle. The last occurrence of "sbus.h" was deleted with commit 0c0db98b50ed1217c0dbf4051722034ba314d06e ("sparc: Remove Documentation/sparc/sbus_drivers.txt"). I'm not sure whether anything relevant for m68k was included in v2.6.27, but it doesn't really matter.

(It started as /include/asm-m68k/shm.h and moved to its current location a few years ago.) It seems it was never used: no file ever included it and nothing used the macros it defines. (Actually, from v2.5.46 until v2.6.29-rc3 it was included by m68knommu's asm/shm.h. But that header was just a very thin wrapper for this header and was itself unused too.) This header can safely be removed.
