The m68k build in 3.0 dies with this:
CC arch/m68k/kernel/dma.o In file included from arch/m68k/kernel/dma.c:4: arch/m68k/kernel/dma_no.c: In function 'dma_sync_single_for_cpu': arch/m68k/kernel/dma_no.c:44: error: implicit declaration of function 'flush_dcache_range' make[1]: *** [arch/m68k/kernel/dma.o] Error 1 make: *** [arch/m68k/kernel] Error 2
That file includes <asm/cacheflush.h>, which for m68k is:
#ifdef __uClinux__ #include "cacheflush_no.h" #else #include "cacheflush_mm.h" #endif
The nommu header (cacheflush_no.h) does #define flush_dcache_range(), but the clacheflush_mm.h version does not. I.E. you can only currently build m68k for Coldfire, you can no longer build it for an actual m68k.
(A git log of Linus' tree shows cacheflush_mm.h hasn't been touched since 2010, and I pulled earlier today.)
