Yes, I'm still the maintainer of the Linux/m68k kernel. I wasn't aware there's an issue with gcc-4.2. Can you please post the problem on the Debian/m68k or Linux/m68k mailing list?
Okay, so I got a cross tool-chain set up on an x86_64 host. Trying to compile a stock 3.0.8 kernel for the m68k architecture gives me: [...] CC [M] lib/crc-ccitt.o CC [M] lib/crc-itu-t.o CC [M] lib/crc7.o CC [M] lib/libcrc32c.o CC [M] lib/bch.o CC [M] lib/ts_kmp.o CC [M] lib/ts_bm.o CC [M] lib/ts_fsm.o CC [M] lib/lru_cache.o LD arch/m68k/lib/built-in.o CC arch/m68k/lib/ashldi3.o CC arch/m68k/lib/ashrdi3.o CC arch/m68k/lib/checksum_mm.o CC arch/m68k/lib/lshrdi3.o CC arch/m68k/lib/memcpy.o CC arch/m68k/lib/memmove.o CC arch/m68k/lib/memset.o CC arch/m68k/lib/muldi3.o CC arch/m68k/lib/string.o CC arch/m68k/lib/uaccess.o AR arch/m68k/lib/lib.a LD vmlinux.o MODPOST vmlinux.o GEN .version CHK include/generated/compile.h UPD include/generated/compile.h CC init/version.o LD init/built-in.o LD .tmp_vmlinux1 init/built-in.o: In function `init_post': /home/ehaase/linux-3.0.8/init/main.c:746: undefined reference to `free_initmem' arch/m68k/kernel/built-in.o: In function `dma_sync_single_for_device': /home/ehaase/linux-3.0.8/arch/m68k/kernel/dma_mm.c:78: undefined reference to `cache_clear' /home/ehaase/linux-3.0.8/arch/m68k/kernel/dma_mm.c:75: undefined reference to `cache_push' arch/m68k/mm/built-in.o: In function `mem_init': /home/ehaase/linux-3.0.8/arch/m68k/mm/init_mm.c:116: undefined reference to `init_pointer_table' /home/ehaase/linux-3.0.8/arch/m68k/mm/init_mm.c:123: undefined reference to `zero_pgtable' /home/ehaase/linux-3.0.8/arch/m68k/mm/init_mm.c:116: undefined reference to `init_pointer_table' kernel/built-in.o: In function `pgd_alloc': /home/ehaase/linux-3.0.8/arch/m68k/include/asm/motorola_pgalloc.h:89: undefined reference to `get_pointer_table' kernel/built-in.o: In function `pmd_free': /home/ehaase/linux-3.0.8/arch/m68k/include/asm/motorola_pgalloc.h:72: undefined reference to `free_pointer_table' kernel/built-in.o: In function `relay_alloc_buf': /home/ehaase/linux-3.0.8/kernel/relay.c:144: undefined reference to `mm_cachebits' mm/built-in.o: In function `pmd_alloc_one': /home/ehaase/linux-3.0.8/arch/m68k/include/asm/motorola_pgalloc.h:67: undefined reference to `get_pointer_table' mm/built-in.o: In function `pmd_free': /home/ehaase/linux-3.0.8/arch/m68k/include/asm/motorola_pgalloc.h:72: undefined reference to `free_pointer_table' mm/built-in.o: In function `__pmd_free_tlb': /home/ehaase/linux-3.0.8/arch/m68k/include/asm/motorola_pgalloc.h:78: undefined reference to `free_pointer_table' /home/ehaase/linux-3.0.8/arch/m68k/include/asm/motorola_pgalloc.h:78: undefined reference to `free_pointer_table' mm/built-in.o: In function `__vmalloc_area_node': /home/ehaase/linux-3.0.8/mm/vmalloc.c:1549: undefined reference to `mm_cachebits' mm/built-in.o: In function `vmalloc_32_user': /home/ehaase/linux-3.0.8/mm/vmalloc.c:1820: undefined reference to `mm_cachebits' mm/built-in.o: In function `vmalloc_32': /home/ehaase/linux-3.0.8/mm/vmalloc.c:1803: undefined reference to `mm_cachebits' mm/built-in.o: In function `vmalloc_exec': /home/ehaase/linux-3.0.8/mm/vmalloc.c:1782: undefined reference to `mm_cachebits' mm/built-in.o: In function `vmalloc_node': /home/ehaase/linux-3.0.8/mm/vmalloc.c:1740: undefined reference to `mm_cachebits' mm/built-in.o:/home/ehaase/linux-3.0.8/mm/vmalloc.c:1716: more undefined references to `mm_cachebits' follow lib/built-in.o: In function `pci_iounmap': /home/ehaase/linux-3.0.8/lib/iomap.c:279: undefined reference to `iounmap' lib/built-in.o: In function `ioremap_nocache': /home/ehaase/linux-3.0.8/arch/m68k/include/asm/io_mm.h:289: undefined reference to `__ioremap' lib/built-in.o: In function `devm_ioremap_release': /home/ehaase/linux-3.0.8/lib/devres.c:8: undefined reference to `iounmap' lib/built-in.o: In function `devm_iounmap': /home/ehaase/linux-3.0.8/lib/devres.c:82: undefined reference to `iounmap' lib/built-in.o: In function `ioremap_nocache': /home/ehaase/linux-3.0.8/arch/m68k/include/asm/io_mm.h:289: undefined reference to `__ioremap' lib/built-in.o: In function `ioremap': /home/ehaase/linux-3.0.8/arch/m68k/include/asm/io_mm.h:285: undefined reference to `__ioremap' drivers/built-in.o: In function `ioremap_nocache': /home/ehaase/linux-3.0.8/arch/m68k/include/asm/io_mm.h:289: undefined reference to `__ioremap' drivers/built-in.o: In function `serial8250_release_std_resource': /home/ehaase/linux-3.0.8/drivers/tty/serial/8250.c:2617: undefined reference to `iounmap' drivers/built-in.o: In function `firmware_loading_store': /home/ehaase/linux-3.0.8/drivers/base/firmware_class.c:251: undefined reference to `mm_cachebits' drivers/built-in.o: In function `ioremap_nocache': /home/ehaase/linux-3.0.8/arch/m68k/include/asm/io_mm.h:289: undefined reference to `__ioremap' /home/ehaase/linux-3.0.8/arch/m68k/include/asm/io_mm.h:289: undefined reference to `__ioremap' make: *** [.tmp_vmlinux1] Error 1 ehaase@precious-lnx:~/linux-3.0.8$ m68k-unknown-linux-gnu-gcc --version m68k-unknown-linux-gnu-gcc (GCC) 4.2.4 Copyright (C) 2007 Free Software Foundation, Inc.
