68000 has different alignment needs to 68020+. memcpy() checks if the destination is aligned and does a smaller copy to fix the alignment and then critically for 68000 it checks if the source is still unaligned and if it is reverts to smaller copies. memmove() does not currently do the second part and malfunctions if one of the pointers is aligned and the other isn't. This is apparently getting triggered by printk. If I put breakpoints into the new checks added by this commit the first hit looks like this: memmove (n=205, src=0x2f3971 <printk_shared_pbufs+205>, dest=0x2f3980 <printk_shared_pbufs+220>) at arch/m68k/lib/memmove.c:82 Signed-off-by: Daniel Palmer <daniel@thingy.jp> Signed-off-by: Greg Ungerer <gerg@kernel.org> |
